IntroductionIntroductionIntroductionIntroduction Chapter focuses on documentation that

identifies the aircraft, its systems, and the work to be done on them.

Controlled Documents Used for operation and/or maintenance of the

aircraft in accordance with FAA regulations Have limited distribution within airline and

require regular revisions and must include list of revisions, active and rescinded page numbers in document

Noncontrolled Documents Furnished by airline and manufacturer

Manufacturer’s Documentation: Airplane Maintenance Manual Component Maintenance Manuals Vendor Manuals Fault Isolation Manual Fault Reporting Manual Illustrated Parts Catalog Storage and Recovery Document Structural Repair Manual Maintenance Planning Data Document Schematic Diagram Manual Wiring Diagram Manual Master Minimum Equipment List (MMEL) Dispatch Deviation Guide Configuration Deviation List Task Cards Service Bulletins Service Letters Maintenance Tips

Manufacturer’s Documentation

Contains the basic information on the operation and maintenance of the aircraft and its on-board equipment

Explanation of how each system and subsystems work

Basic Maintenance and Servicing action such as R&R of LRUs

Functional Tests, Operational Tests, Adjustments, Replenishing of fluids and other servicing tasks

Airplane Maintenance Manual (AMM)

Component and vendor manuals are for components that are to be removed for maintenance in the shop

The manuals provide same type of information on components that the AMM provides for aircraft and its systems

Component and Vendor Manuals

Contains a set of isolation trees for the purpose of pinpointing and fixing numerous problems related to the various systems and components on the aircraft.

Fault Isolation Manuals

Used by Flight Crew to provide maintenance with advanced warning of malfunctions and an indication of where to begin looking for a solution prior to aircraft’s arrival.

Identifies their problem using a series of questions and diagrams of system operation and instrument indication

Leads to 8 digit code used by maintenance to determine solution

Fault Reporting Manual

Produced by the airframe manufacturer and includes lists and location diagram of all parts used on the aircraft model

Provides information on location, part numbers, vendors, interchangeability of parts

Illustrated Parts Catalog

Info on maintenance and servicing of aircraft that are to be out of service and stored for a long period of time

Procedures for draining fluids, moving aircraft so the tires will not go flat, and protecting components from the weather

Storage and Recovery Document

Contains information for certain repairs of the aircraft structure

These simple repairs are approved by FAA to be completed by the operator

Other repairs must be done by the airframe manufacturer or some other FAA designated repair facility

Structural Repair Manual

Provides the airline operator with a list of maintenance and servicing tasks to be performed on the aircraft

Tasks are divided into groupings Daily, Transit, Letter Checks, Hourly Limits,

Cycle Limits

Tasks are divided into Letter Checks Hours, cycles, and calendar time

Maintenance Planning Data Document

Contains diagrams of the electrical, electronic, and hydraulic systems

Can be block diagram and often contain detailed diagrams

Wiring harnesses, connectors, and interfacing equipment

Schematic Diagram Manual

Shows the complete run of wiring, including cable bundle numbers and routing, plug and connector numbers and locations, bulkheads, and other structural elements through which the wiring is routed.

Wiring Diagram Manual

Identifies the equipment which may be degraded or inoperative

Systems that the flight crew may agree to accept in a degraded or inoperative condition – as long as it is fixed in a prescribed time limit set by the MMEL

Contains information on all equipment available on the aircraft model to which it applies

Master Minimum Equipment List (MMEL)

MMEL items that require maintenance prior to deferral and dispatch

May need to pull and placard certain circuit breakers, disconnect power, tie up loose cables for removed equipment, and various other actions to secure aircraft and the systems against inadvertent operation

Dispatch Deviation Guide

Involves configuration of the aircraft rather than systems and equipment

Provides information on panels, fairings, and similar variations in configuration that be nonstandard at dispatch as long as it does not affect the safety of flight

Configuration Deviation List (CDL)

Certain tasks for removal/installation, testing, servicing, and similar maintenance items are produced on separate cards or sheets so that a mechanic can perform the action without taking the whole manual

Task Cards

SB is a modification of a system that will provide improved safety or operation of a system and includes detailed description of the work and parts required.

SL provides information to improve maintenance actions without equipment modification

Maintenance tip is suggestion to assist in their work or improve conditions

Service Bulletins, Service Letters, and Maintenance Tips

Federal Aviation Regulations (FARs)

Advisory Circulars

Airworthiness Directives

Notice of Proposed Rule Making (NPRM)

Regulatory Documentation

• Federal laws are collected in a document called the code of federal regulations (CFRs)

• Laws for commercial aviation are under title 14 of this code – aeronautics and space – parts 1 through 200

• Certification and operation of large, commercial aircraft are part 121

• Noted as 14 CFR 121

Federal Aviation Regulations (FARs)

• A document to provide the “means, but not the only means” of complying with a regulation

• Allows leeway in how regulations are to be met without micro managining the operator

Advisory Circulars (ACs)

• Substantial regulations issued by the FAA to correct unsafe conditions that exist in a product (aircraft, aircraft engine, propeller, or appliance)

• Aircraft owners / operators are required to maintain the aircraft in compliance with all ADs

• AD include:• Description of the condition; the product to which

the AD applies; corrective action required; date of compliance; where to get additional information; information on alternative methods of compliance if applicable

Airworthiness Directives (ADs)

• FAA issues in advance of FAR in advance in order for the industry to have ample time to study and comment on the proposed rule change.

Notice of Proposed Rule Making (NPRM)

• Operation Specifications• Technical Policies and Procedures

Manual• Inspection Manual• Reliability Program Manual• Minimum Equipment List• Task Cards• Engineering Orders

Airline Generated Documentation

• Required for each aircraft type flown

• Details the airline’s maintenance, inspection, and operations programs

Operations Specifications (Ops Specs)

• Usually written by engineering

• Defines how all Maintenance and Engineering functions should be carried out

Technical Policies and Procedures Manual (TPPM)

• Contents relate to all inspection activities within M&E

• Mechanic inspections• QC Inspection tasks• Special Inspections (hard landings, bird strikes, etc)• Airline’s required inspection item (RII) program• The paperwork, forms, and reports required to carry

out these functions

Inspection Manual

• Defines the duties and responsibilities of the QA department and defines the processes and procedures used in the annual quality assurance audits

• Forms used and reports are also covered along with the procedures for the follow-up and enforcement of QA write-ups

Quality Assurance Manual (QA)

• Defines the relaibility program in detail so that the FAA can evaluate and approve all its elements at one time.

Reliability Program Manual

• Is a customizable MMEL for the owner/operators particular airframe/engine configuration

• Must carry copies in each aircraft for flight crew reference

Minimum Equipment List (MEL)

• Produced by the manufacturer for usually one action

• Simplifies tasks

• Engineering section responsible for creating cards to ensure technical accuracy

Task Cards

• Maintenance work not covered in the standard maintenance plan developed by engineering

• The EO must be issued as a work order

Engineering Orders (EO)

• ATA Standard Chapter Numbers (pg 66)

• ATA Airplane Maintenance Manual Page Block Assignments (pg 68 – 70)

ATA Document Standards

• Purpose of the TPPM is to identify all aspects of the maintenance and engineering organization

• Identification of key personnel, descriptions of their job functions and their qualifications

• Definition of the operator’s philosophy and goals• Layout drawings and maps of the maintenance

facilities including shops, ramps, and other significant buildings and areas related to maintenance activities

• Specific items IAW FAA regulations,

• Controlled document – refer to pgs 71 - 73
