1-00-01-01 Policy
1. General
The Minimum Equipment List (MEL) for each aircraft type is prepared to comply with each respective FAA Approved Master MEL and FAA Approved Airplane Flight Manual (AFM). The authority to operate under the MEL is contained in KAL’s Operations Specifications D95
2. Regulatory Standards
A. Allowable Operation Standard: MEL
1) General
Modern transport aircraft is equipped with duplicated systems, components, instruments, electric communication facilities, structure, and important parts so that it may maintain its flight airworthiness and assure its reliability in spite of a malfunction of any parts. MEL is established for above reason. But MEL does not include items which are essentially required for the flight such as Wing, Rudder, Engine, Flap and Landing Gear and non-airworthiness related items like Cabin equipment, Cargo Loading Items, Minor airframe parts excluding major structure, etc.
2) Purpose
The purpose of the MEL is to dispatch the aircraft punctually within acceptable level of safety limit in operating the aircraft.
3) Creation and Revision
A) The MEL is created /revised in compliance with MMEL (Master MEL) which is approved by Airworthiness Authority of Manufacturer.
B) KAL MEL should be approved by the Korean Airworthiness Authority.
C) The MEL is complied with the KAL MEL of each aircraft type approved by the Korean Airworthiness Authority.
4) Application and Limitation
777 MEL Preamble Policy Section 1
1-00-01-01.2 27 JUN 2011
A) When an abnormal condition covered by MEL occurs, the aircraft is applied per MEL by means of “Defer” referred to section 2. B. Classification and Policy for Defer.
B) Items or components which are not installed on the aircraft are not applied.
C) Items and contents which are not prescribed in this MEL follow the AFM or information from manufacturer
D) Optional item for operator’s convenience, affected items can be removed or block/deactivation or can be converted to the alternative way which does not affect airworthiness and safety.
B. Classification and Policy for Defer
1) Defer
“Defer” is used as a special term in Korean Air, which means to carry over the corrective action due to lack of parts, manpower, scheduled commitments, etc. Defect on the aircraft found on the base or at the station should be cleared before the flight. But if the defect doesn’t affect the airworthiness or the flight, the correction can be deferred. The defect will be corrected as an unscheduled maintenance.
2) Defer conditions are as follows:
A) Malfunction included in MEL Items For inoperative items covered by Minimum Equipment List (MEL), Flight Requirements of this policy is applied.
B) Malfunction included NEF (Nonessential Equipment & Furnishings) Items For inoperative items covered by NEF Program, the defer method and procedure are described in KALMOI I31503 NEF List and the policies are in MPPM PF-01-04 NEF Program. • Defects of non-airworthy items like cargo loading/unloading,
passenger convenience items, or Flight Crew/Flight Attendant Rest Area Convenience Items etc.
C) Malfunction has the allowable limits in Maintenance Manual or Maintenance Program. • Defects like fuel or hydraulic leaking, tire worn, window crack,
etc, are within Maintenance Manual limits. • Defects in aircraft structure/sub-structure are within manual
(AMM, Structural Repair Manual, etc.) limits or necessary
777 MEL Preamble Policy Section 1

actions for the defects are performed according to the recommendation of manufacturer/vendor
3) Defer Procedure
A) Deferred defects should be recorded on the flight log at the airport where the defects occurred.
B) If correction is available, it should be done immediately.
C) Defects affected by MEL should be corrected within the time limit excluding the calendar day the malfunction was recorded in the aircraft maintenance log and/or record.
D) Deferred defects and corrective actions should be recorded on the proper form besides the logbook. And the condition of the defect should be watched till the defect is totally cleared.
E) Detail procedure are described in ‘MPPM PF-01-02 Defer’
4) Scope of Repair Interval
A) Corrective actions for defects should be accomplished as soon as personnel, facility, equipment, property and time is secured. If it is impossible to correct defects, it can be defer. And in that case, it should be corrected by the time when is referred in Repair Interval designated as category.(Refer to page 1-00-01-03.3, Definition No.22 Repair Interval)
B) The above limit days are regarded as the term from midnight of the deferred date to midnight of the expired date. (Refer to page 1-00-01-03.3, Definition No.22 Repair Interval)
C) If the expire date falls on any day during schedule maintenance, it can be extended until the schedule maintenance are completed.
D) The certificate holder is authorized to use a continuing authorization to approve extensions to the maximum repair interval for category B and C items as specified in the approved MEL, provided those extensions are reported to the Korean Airworthiness Authority as soon as all their terminating actions are fully completed.
E) Detail procedures are described in 'MPPM PF-01-02 Defer'.
5) Decision to Defer
777 MEL Preamble Policy Section 1
1-00-01-01.4 27 JUN 2011
A) Before door close: Captain, dispatcher, and the responsible maintenance personnel must exchange views with one and another regarding applicable defects. If the malfunction range may be satisfied in accordance with applicable standards, and acceptance level of safety is assured, the departure is released. The responsible maintenance personnel should provide information and explain about corrective action to captain or dispatcher if necessary.
B) After door close: The flight crew may defer as required by the designated MEL items. The aircraft may continue on a planned journey to a base where maintenance will repair or re-defer.
Crew Defer procedureThe procedure that the flight crew may apply when malfunction occurs between closing of the doors and increase of thrust for takeoff, and indicated by ‘Crew Defer’ in the ‘After Door Close’ column of the MEL.
Note) Flight crew must return to ramp when ‘Return To Gate’ is marked in the ‘After Door Close’ column of the MEL.
• If Crew Defer Procedure is applied by flight crew, accomplish the (O) procedure in the MEL before takeoff.
• The "INOPERATIVE" tabs located at the bottom of cockpit Aircraft Placard (KAL-MA-435A) must be torn off and placed on inoperative instruments, switches and lights.
• The flight crew notify the contents of Defer to MC with available communications (ACARS, SATCOM, etc.) after carrying out Crew Defer.
• If the flight is continued after applying the Crew Defer Procedure, the flight crew shall record the fact of carrying out the Crew Defer procedure based on MEL in the flight & maintenance log as the following before the flight duty ends.

Preamble Definition Section 1
1-00-01-03.1 23 OCT 2013
1-00-01-03 Definition 1. Accessible Lavatory Items. Accessible lavatory items include: ability to enter
lavatory and maneuver by means of on-board wheelchair. The lavatory shall provide accessible door locks, call buttons, grab bars, faucets, other controls, and dispensers. As an air carrier, you must maintain all aircraft accessibility features in proper working order.
2. Administrative Control Item (ACI). An ACI is listed by the aircraft operator in the MEL for tracking and informational purposes. As an example, ACI may be used to track ETOPS accomplishment of required APU cold-soak, or in-flight verification starts. An ACI may be added to an aircraft operator’s MEL by approval of the POI provided no relief is granted, or provided conditions and limitations are contained in an approved document (e.g., Structural Repair Manual (SRM) or Airworthiness Directive (AD)). If relief other than that granted by an approved document is sought for an ACI, a request must be submitted to the Administrator. If the request results in review and approval by the FOEB, the item becomes an MMEL item rather than an ACI
3. ATA System Page. The ATA system page is divided into four (4) columns and contains: item and repair category; number installed; number required for dispatch; and remarks or exceptions. Standard ATA categories are used. Items are numbered sequentially.
A. Item. This column depicts the equipment, system, component, or function listed in the “Item” column.
B. Repair Category. See definition #24. C. Number Installed. This column depicts the number (quantity) of
instrument and equipment items normally installed in the aircraft. This number represents the aircraft configuration considered in developing this MEL. Should the number be a variable (e.g., fleet configuration differences, cockpit lighting items, cabin lighting items, cargo restraint components) a number is not required and the “-” symbol is used.
D. Number Required for Dispatch. This column depicts the minimum number (quantity) of instrument and equipment items required for operation provided the conditions specified in the “Remarks or Exceptions” column are met. Where the MMEL shows a variable number required for dispatch, The MEL must reflect the actual number required for dispatch or an alternate means of configuration control approved by the Administrator.
E. Remarks or Exceptions. This column may include a statement(s) either prohibiting or permitting operation with a specific number of instrument and equipment items inoperative, provisos (conditions and limitations) for such operation, and appropriate notes.
F. Provisos. Provisos are indicated by a number or a lower case letter in
777 MEL
Preamble Definition Section 1
1-00-01-03.2 23 OCT 2013
“Remarks or Exceptions”. Provisos are conditions or limitations that must be complied with for operation with the listed instrument or equipment item inoperative.
G. Notes. Notes provide additional information for crewmember or maintenance consideration. Notes are used to identify applicable material, which is intended to assist with compliance, but do not relieve the aircraft operator of the responsibility for compliance with all applicable requirements. Additional notes may be amended, deleted, or added to the MEL by the aircraft operator, as appropriate. Notes are not a part of the provisos.
H. Vertical Bar (change bar). A vertical bar Indicates a change, addition, or deletion in the adjacent text for the current revision of that page only. All change bars applicable to the previous revision of the MMEL are removed prior to the release of the next revision.
4. The approved flight manual for the specific aircraft is listed on the applicable Type Certificate Data Sheet (TCDS). The approved flight manual is the source document for operational limitations and performance parameters for an aircraft. The term “approved flight manual” can apply to an AFM.
5. Reserved 6. Reserved 7. Considered Inoperative. The phrase, “Considered Inoperative”, as used in
the provisos, means that an instrument and equipment item must be treated for dispatch, taxi and flight purposes as though it were inoperative. The item will not be used or operated until the original deferred item is repaired. Additional actions include: documenting the item on the dispatch release (if applicable), placarding, and complying with all remarks, exceptions, and related MEL provisions, including any (M) and (O) procedures and observing the repair category.
8. Continuing Authorization – Single Extension. An aircraft operator who has the authorization to use an approved MEL may also have the authority to use a continuing authorization to approve a single (one-time) extension to the repair interval for category B or C items in accordance with Operations Specification D095. Continuing Authorization – Single Extension is not authorized for repair category A and D items.
9. Dash (-). Indicates a variable number (quantity) of the instrument and equipment items may be installed or required for dispatch. This is common when a fleet MEL is used since aircraft of the same make and model may have differing numbers of specific instrument and/or equipment items installed.
10. Day of Discovery. This is the calendar-day an equipment/instrument malfunction was recorded in the aircraft maintenance record/logbook. This day is excluded from the calendar-days or flight-days specified in the MEL for the repair interval of an inoperative instrument and/or equipment item. This provision is applicable to all MEL items; i.e., categories A, B, C, and D.
777 MEL
Preamble Definition Section 1
1-00-01-03.3 23 OCT 2013
11. Deactivated and/or Secured. When the MEL refers to an instrument and/or equipment item as deactivated and/or secured, the specified component must be put into an acceptable condition for safe flight. An acceptable method of deactivating and/or securing will be established by the aircraft operator.
12. Deleted. "Deleted” in the remarks column after a sequence item indicates that the item was previously listed but is now required to be operative if installed in the aircraft.
13. Extended Range Operations (ER). ER refers to extended range operations (ETOPS) of an airplane with operational approval to conduct ETOPS in accordance with the applicable regulations.
14. Excess Items. Excess items are those instrument and equipment items that have been installed that are redundant to the requirements.
15. Flight Day. A flight-day is a 24-hour period (from midnight to midnight) either universal coordinated time (UTC) or local time, as established by the aircraft operator, during which at least one flight is initiated for the affected aircraft.
16. Heavy Maintenance Visit (HMV). HMV is a scheduled C-check/D-check or airworthiness maintenance program inspection where the aircraft is scheduled to be out of service for 4 or more days.
17. Icing Conditions. An atmospheric environment that may cause ice to form on the aircraft (structural) or in the engine(s) (induction).
18. Inoperative. A system and/or component malfunction to the extent that it does not accomplish its intended purpose and/or is not consistently functioning normally within its approved operating limit(s) and/or tolerance(s).
19. Inoperative Components of an Inoperative System. Inoperative instrument and equipment items, which are components of a system that is inoperative, are usually considered components directly associated with and having no other function than to support that system (warning/caution systems associated with the inoperative system must be operative unless relief is specifically authorized per the MEL).
20. Is Not Used. The phrase “Is Not Used” in the provisos, remarks or exceptions for an MEL instrument or equipment item may specify that another item in the MEL “is not used”. In such cases, crewmembers must not activate, actuate, or otherwise utilize that item under normal operations. It is not necessary for aircraft operators to accomplish the (M) procedure(s) associated with the item. However, operational requirements must be complied with, and an additional placard must be affixed, to the extent practical, adjacent to the control or indicator for the item that is not used. This informs crewmembers that an instrument or equipment item is not to be used under normal operations.
21. Nonessential Equipment and Furnishings (NEF). NEFs are those items installed on the aircraft as part of the original type certification (TC), STC, or other form of alteration that have no effect on the safe operation of flight and
777 MEL
Preamble Definition Section 1
1-00-01-03.4 23 OCT 2013
would not be required by the applicable certification rules or operational rules. They are those items that, if inoperative, damaged, or missing, have no effect on the aircraft’s ability to be operated safely under all operational conditions. NEF items are not instrument and equipment items already identified in the MEL or CDL of the applicable aircraft. They do not include instrument and equipment items that are functionally required to meet the certification rule or for compliance with any operational rule.
22. Operative. An operative system and/or component will accomplish its intended purpose and is consistently functioning normally within its design operating limit(s) and tolerance(s). When an MEL item specifies that an item of equipment must be operative, it does not mean that it’s operational status must be verified; it’s to be considered operative unless reported or known to be malfunctioning. When an MEL item specifies that an item of equipment must be verified operative, it means that it must be checked and confirmed operative at the interval(s) specified for that MEL item. When an MEL item specifies that an item of equipment must be verified but no interval is specified, verification is required only at the time of deferral. Other terminology sometimes used interchangeably with “operative” within the MEL is “operates normally”, "fully operative", and "considered operative”.
23. Placarding. Each inoperative instrument or equipment item must be placarded to inform and remind the crewmembers and maintenance personnel of the item condition. To the extent practical, placards should be located adjacent to the control or indicator for the item affected; however, unless otherwise specified (i.e. AFM), placard wording and location will be determined by the aircraft operator.
24. "Day Operation" means an any flight conducted from the point of take off to that of landing between 30 minutes before sunrise and 30 minutes after sunset.
25. Extended Overwater Operation: Any flight conducted over 50 nautical mile distance from the nearest coast.
26. "Approach minimums" is the requirement for CAT-II/III operations. Required number of system(s) or equipment(s) for dispatch is listed in 0-4 CAT-II/III Operation Equipment List.
27. "Over-the-top" means above the layer of clouds or other obscuring phenomena forming the ceiling, under VFR when it is not being operated on an IFR flight plan.
28. Area Navigation (RNAV) is defined as a method of navigation which permits aircraft operation on desired flight path within the coverage of ground navigation facilities or within the capability of self-contained navigation aids, or a combination of these. a. B-RNAV Operation Procedures
Basic Area Navigation (B-RNAV) is a navigation performance which is a required track-keeping accuracy of ± 5NM for at least 95% of flight time in European airspace.
777 MEL
Preamble Definition Section 1
1-00-01-03.5 23 OCT 2013
b. P-RNAV Operation Procedures in Europe Precision Area Navigation (P-RNAV) is a navigation performance requirement for RNAV instrument flight procedure in designated European terminal airspace. It requires aircraft conformance to a track-keeping accuracy of ± 1NM for at least 95% of flight time.
29. RNP-X : It requires aircraft performance to a track-keeping accuracy of ± X NM (1 : terminal, 4 or 10 : oceanic) for at least 95% of flight time. On-board performance monitoring and alerting are required.
30. RNP AR approach is defined as an RNP approach procedure that requires a lateral TSE(Total System Error) as low as +/- 0.1 NM on any segment of the approach procedure and also require that a specific vertical accuracy be maintained.
31. North Polar Region: the area north of 78 degree north. 32. Cross Polar Routes general
The current cross polar routes established between North America and Asia consists of 4 routes that is polar 1,2,3,4. of above 4 KAL use Polar 3 and Polar 4.these two routes locates Canadian ACA and Russia Magadan OCA airspace. Polar 3 route pass up to 85N while polar 4 passes south of 80N.
33. "Once each flight day" means that these items are required to be checked at least once each flight day. This check need not be performed prior to the first flight of the day, but at least once each flight day.

1-00-02-01 EICAS Message - Introduction
Introduction - EICAS Messages Cross Reference List A Cross Reference List of Engine Indication and Crew Alerting System (EICAS) messages and corresponding MEL items is provided in this section. The Cross Reference List is intended to assist operators in quickly identifying the proper MEL item to consult for possible dispatch relief. All EICAS messages at Status level or higher are listed by message text in alphabetic order. A description of the information provided in each column of the Cross Reference List follows.
Message Text This column alphabetically lists each message exactly as they would appear on EICAS.
Level The appropriate EICAS message level is listed: Warning, Caution, Advisory, Memo, Comm, or Status.
MEL Item This column lists the appropriate MEL item(s) to consult for possible dispatch relief with the associated message displayed. EICAS messages that do not have a specific MEL item to allow dispatch are listed with one of the following cross references:
N/A Not Applicable: There is no MEL item listed because the message does not indicate a system failure.
None There is no MEL item for the failure condition indicated by this message. NO DISPATCH

EICAS Messages EICAS is the primary means of displaying airplane system information to the flight crew. EICAS consolidates engine and subsystem indications and provides a centrally located crew alerting function. EICAS displays System Alerts (Warning, Caution, and Advisory), Communication Alerts, Memo messages, and Status messages.
Warning A non-normal operational or system condition displayed in red text accompanied by annunciation of the master warning lights and an aural tone. Immediate crew awareness and corrective action is required.
Caution A non-normal operational or system condition displayed in amber text accompanied by annunciation of the master caution lights and an aural tone. Immediate crew awareness is required and corrective action may be required.
Advisory A non-normal operational or system condition displayed in amber text without other visual or aural annunciations. Routine crew awareness is required and corrective action may be required.
Comm A reminder of normal incoming flight crew communications displayed in white text.
Memo A reminder of a normal condition in white text that indicates the current state of certain manually and automatically configured airplane systems.
Status A system condition which affects airplane dispatch, displayed in white text on the MFD status page. Status messages are checked prior to engine start and the condition should be corrected or dispatched per the operator’s MEL. There are no inflight crew procedures associated with Status messages.

Maintenance Level Messages Maintenance level messages are not included in the Cross Reference List, since they do not affect the airworthiness release of the airplane. Maintenance level messages are provided by EICAS and the Central Maintenance Computing System (CMCS) as follows:
Scheduled Maintenance Task (SMT): These are a special category of EICAS messages that are uniquely associated with a Certification Maintenance Requirement (CMR) or a Scheduled Maintenance Task (SMT). They are displayed on a special MFD maintenance page. SMT messages are checked as a result of a specified maintenance task defined by the CMR or maintenance program requirement, which also defines a specific time interval when corrective maintenance action is required. There is no requirement to check SMT messages prior to each flight. SMT messages are not included in the Cross Reference List.
Central Maintenance Computing System (CMCS) Messages: The Central Maintenance Computing Function of the Onboard Maintenance System processes BITE fault reports into maintenance messages. These are nonessential messages that are displayed on the Maintenance Access Terminal (MAT). Maintenance messages are not displayed on EICAS and they are not used to determine the airworthiness of the airplane. They provide diagnostic information useful in troubleshooting or maintenance planning. There are two general types of CMCS maintenance messages: correlated and uncorrelated. Correlated messages are associated with a specific EICAS message or other flight deck effect. Each fault indicated by an EICAS message has at least one correlated maintenance message to assist the maintenance personnel in determining the root cause of the fault indicated on EICAS. Uncorrelated messages do not have a corresponding flight deck effect. Some uncorrelated messages, known as Maintenance Memos, provide information regarding the condition of a redundant component or system that is installed to enhance departure reliability, but is not required for certification. Maintenance Memos provide airline maintenance departments the ability to monitor system degradation and plan appropriate action before annunciation of an EICAS message which affects the airworthiness release of the airplane. CMCS maintenance messages are not included in the Cross Reference List.

Considerations for Dispatch with Displayed EICAS and CMCS MessagesAny monitored faults that affect airplane dispatchability will be displayed on EICAS as a Status or Alert level (Warning, Caution, Advisory) message, with a corresponding correlated maintenance message. System faults displayed at Status level or Alert level should be resolved by MEL compliance or maintenance action prior to engine start. After engine start, EICAS Alert messages are the primary means of alerting the crew to non-normal conditions or improper configuration. Display of any Alert message requires accomplishment of the appropriate non-normal procedure by the crew. Upon completion of the procedure and prior to takeoff, the operator’s MEL should be consulted to determine if relief is available for continued operation with system faults displayed at the Alert level (Warning, Caution, Advisory).
Any system faults that result only in a SMT message or a CMCS maintenance message do not require MEL consideration or maintenance action prior to dispatch. They are addressed within an operator’s standard maintenance program.
Considerations for Dispatch Using Synoptic Displays Airplane system faults and/or ARINC 629 communication faults may result in missing information on synoptic displays. Missing data may include any synoptic display element such as flow bars, pump or valve symbols, and digital indications. Display elements may be absent from one, two, or all three Multi-Function Displays. Missing information on a specific synoptic page caused by an ARINC 629 communication fault is not indicative of a fault in the system associated with that synoptic page. Decisions regarding dispatch should be based on EICAS Status or Alert level messages and/or other flight deck effects.

1-00-02-02 EICAS Message - Cross Reference List
- L (Message Level) : W (Warning), C (Caution), A (Advisory), M (Memo), S (Status), COM (Comm), N (Nuisance)
- A/D/C(After Door Close) : RTG(Return to gate), CD(Crew Defer) - During engine start and prior to take-off, it is not necessary to check status
messages as any message having an adverse effect on safe continuation of the flight, and requiring crew attention, will appear as an EICAS alert message (warning, caution, or advisory). But Particular MEL items can be only distinguishable by checking with the combination of EICAS alert and status messages. So the EICAS status message may be required to be checked when identifying which MEL item is applicable.
