TIME LIMITS / MAINTENANCE CHECKS

1. General

This chapter has three sections:

• Time Limits 05-10-00

• Scheduled Maintenance Checks 05-20-00

• Unscheduled Maintenance Checks 05-50-00

2. Time Limits

The Time Limits section gives the life and / or the overhaul and replacement / inspection intervals related to the aircraft, its systems and the components / parts installed.

3. Scheduled Maintenance Checks

This section gives the instructions related to the maintenance checks and inspections that must be done on the aircraft at the scheduled / specified intervals.

4. Unscheduled Maintenance Checks

This section gives the instructions related to the maintenance checks and inspections that must be done on the aircraft after a special or unusual incident has occurred. These maintenance checks and inspections are necessary to find possible damage to the aircraft.

5. Permissible Tolerances

The following paragraphs give the permissible tolerances and extensions for flying hours, cycles (landings) and calendar based maintenance intervals.

It is the responsibility of the owner or operator to make sure that any maintenance interval extension is accepted by the Airworthiness Authority of the country of registration of the affected aircraft.

If you do the maintenance inside the permissible tolerance limits, the next planned maintenance times do not change, e.g:

• If the standard interval is 100 hrs, the permissible tolerance is ± 10 hrs. If the maintenance work is done inside the shaded tolerance band, the maintenance intervals do not change:

You can do the maintenance earlier than the permissible tolerance limit, but if you do this the next planned maintenance times do change, e.g:

• If the standard interval is 100 hrs, the permissible tolerance is ± 10 hrs. If the maintenance work is done earlier and outside the shaded tolerance band, the maintenance intervals do change:

These tolerances do not apply to the maintenance tasks in Chapter 04, Airworthiness Limitations.

A. Flying Hour Based Intervals

100 flying hours or less: ± 10 flying hours.

More than 100 flying hours: ± 10%, but not more than 500 flying hours.

B. Cycle Based Intervals

500 cycles or less: ± 10%, but not more than 25 cycles.

More than 500 cycles: ± 10%, but not more than 500 cycles.

C. Calendar Time Based Intervals

1 year or less: ± 10%, but not more than 1 month.

More than 1year: ± 10%, but not more than 6 months.

TIME LIMITS

1. General

This section has two subjects:

• Overhaul and Replacement Schedule 05-10-10

• Time Limited Maintenance Requirements 05-10-20

The time limits given in this section are based on average usage of the aircraft and average environmental conditions.

The time limits given are not a guarantee that the item will reach the time without malfunction as the base factors cannot be controlled by the manufacturer. This is specially applicable to aircraft that are operated in very hot and humid climates, or very cold and damp climates, or salt-laden atmospheres, etc.

The date of manufacture of the aircraft (given on the aircraft data plate) is used as the basis for all time limited items listed in this section.

The subsequent monitoring procedure for all the calendar time limited items after their initial replacement or inspection, will be in elapsed time or installed time. This is given with each component interval in sections 05-10-10 and 05-10-20.

Elapsed time is the time interval since manufacture of the component.

Installed time is the time interval since the installation of the component on the aircraft.

For the calendar based time limited items, the inspection requirement is to be done no later than the last day of the month of the calendar interval given. This is also applicable to all the subsequent calendar time limited inspection requirements.

It is the responsibility of the owner or operator to make sure that the times are monitored correctly.

2. Overhaul and Replacement Schedule

This subject gives a recommended list of all components which have an overhaul life or a maximum life limit. The time limits for the components are based on flying hours, calendar time or number of flights. The first overhaul or replacement of a component must be done not later than the stated time limit (the permissible tolerances given in 05-00-00 are applicable). The condition of the component can be used as a criterion (to calculate subsequent time limits applicable to the individual aircraft or fleet operation) if the operator has an approved condition-monitoring system.

The requirements of this subject can be accomplished by:

• Overhaul (disassembly, inspection, assembly and test) of the component in accordance with the applicable Component Maintenance Manual (CMM)

• Replacement with components purchased from Pilatus Aircraft Limited (items that can be overhauled can be returned to Pilatus for exchange).

Compliance with one of these two options is at the discretion of the maintenance center responsible for the work related to the time limit requirement.

EFFECTIVITY: All

05-10-00

Page 2Jul 30/17


Components not listed as lifed or to be overhauled do not have a specified life. These components need only be replaced when their condition shows that replacement is necessary.

3. Time Limited Maintenance Requirements

This subject gives a list of the items that must have an inspection and / or test at intervals that are based on flying hours, calendar time or the number of flights. To give the best utilization, each item listed in this subject is given an individual optimized periodicity. For this reason these items are listed separately from the scheduled Inspection Requirements given in section 05-20-00. When a scheduled inspection is due, check to see if there are Time Limited Maintenance Requirements due at the same time.

SCHEDULED MAINTENANCE CHECKS

1. Inspection Requirements

As required by FAR Part 91, the aircraft must have a complete Annual Inspection each 12 calendar months of operation.

An Annual Inspection includes all the 100 Hour Inspection items.

The inspection intervals are based on normal usage of the aircraft under average environmental conditions. Aircraft operated in very hot and humid climates, or very cold and damp climates, or salt-laden atmospheres, may need more frequent inspections for wear, corrosion and lubrication. Under these adverse conditions the 100 Hour Inspection should be done in compliance with the inspection sheets at a more frequent interval until the owner or operator can set his own inspection interval based on field experience.

For the permissible tolerances of maintenance intervals, refer to 05-00-00.

The owner or operator is primarily responsible for maintaining the aircraft in an airworthy condition. This includes compliance with Airworthiness Directives and any additional maintenance requirements from the Time Limits section of this chapter. It is further the responsibility of the owner or operator to make sure that the aircraft is inspected in accordance with the inspection sheets.

2. Recommended Scheduled Inspection Intervals

The aircraft maintenance cycle is completed each 7000 flying hours, or 14 years if this occurs first.

• 100 Hour Inspection

The 100 Hour Inspection must be done each 100 flying hours, or each year if this occurs first.

• Annual Inspection

Aircraft operated under civil regulations must have an Annual Inspection each 12 months.

• Partial Overhaul

A Partial Overhaul must be done when or before the aircraft completes 3500 flying hours, or at 7 years if this occurs first.

• Complete Overhaul

A Complete Overhaul must be done when or before the aircraft completes 7000 flying hours, or at 14 years if this occurs first.

When a Complete Overhaul is done the aircraft maintenance cycle starts again.

EFFECTIVITY: All

3. Scheduled Inspection Procedures

The sections used for Scheduled Inspection procedures are:

• Flight Maintenance 05-21-00

• 100 Hour / Annual Inspection 05-22-00

• Partial Overhaul 05-23-00

• Complete Overhaul 05-24-00

4. Inspection Sheets

The inspection sheets list the maintenance items for inspection and state the level of inspection required. The sheets have been prepared to assist the owner or operator in meeting the foregoing responsibilities. They include, together with the inspection requirements, cross references to the maintenance procedures which are necessary to do the inspections.

The inspection sheets are not intended to be all-inclusive, for no such sheets can replace the good judgement of a qualified mechanic in the performance of his duties. As the one primarily responsible for the airworthiness of the aircraft, the owner or operator should select only qualified personnel to maintain the aircraft.

5. Inspection Guidelines

The inspection sheets can be copied and should be used to do the inspections. Detailed information of systems and sub-systems on the aircraft can be found in the applicable chapters of this maintenance manual and the Engine Maintenance Manual (EMM). On the inspection sheets, reference is made to the applicable inspection, repair, removal and installation procedures in this manual, the EMM and Pilatus-issued Service Bulletins. It is the responsibility of the owner or operator to make sure that the mechanics who do the inspections have access to these documents as well as the inspection sheets.

6. Inspection Terms and Definitions

CHECK Compare a measurement of time, pressure, temperature, resistance, dimension or other quantity with a specific figure for that measurement.

COMPLETE OVERHAUL

1. General

This section gives details of the inspections necessary for a Complete Overhaul.

For Complete Overhaul the sections used are:


• Engine 05-24-02

• Electrics/Instruments 05-24-03


Inspection procedures have been prepared in the style of work sheets. Operators may copy pages for use as on the job work sheets.

CAUTION: IF REVISIONS ARE ISSUED FOR THIS SECTION, OPERATORS MUST MAKE SURE THAT OLD WORK SHEET COPIES ARE DESTROYED. NEW WORK SHEETS MUST TEN BE COPIED FROM THE REVISED PAGES.

In each section, work items are grouped into aircraft areas or systems. The maintenance manual chapters, listed with each group, must be referred to during the inspection.

A component found to be defective during inspection or overhaul must be replaced or overhauled.

During these inspections make sure that:



• Refer to 05-10-00 for component lives and components subject to overhaul

NOTE: For the engine and propeller component life limits refer to the Service Bulletin or Service Letter issued by the manufacturer.

2. Complete Overhaul

A Complete Overhaul must be done when or before the aircraft completes 7000 flying hours or at 14 years if this occurs first.

When a Complete Overhaul is done the aircraft maintenance cycle starts again.
