MAINTENANCE PROCEDURES Flashcards
An aircraft maintenance program is essential to allow for safe and economic operations and it is necessary to obtain a type certificate. The entire program is written and known as the _______
Maintenance Planning Document (MPD)
The committee proposes changes to the manufacturer’s maintenance program and issues a report. The report, known as the _________, is review by regulatory authorities for implementation
Maintenance Review Board Report (MRBR)
An ______ chaired by a representative of the airlines and co-chaired by the aircraft manufacturer receives and reviews information pertaining to the maintenance of an aircraft.
Industry Steering Committee (ISC)
It is the _____ job to process any information from the field operators and design engineers for use by the ISC when considering changes to the manufacturer’s maintenance program
aircraft manufacturer’s
All modifications to a maintenance operator’s own maintenance program must be approved by _____
authorities (NAA and EASA)
A modification which has no impact on weight, center of gravity, structural strength, reliability, characteristics of usage, or any other characteristic which has an impact on the airworthiness of the systems is known as a _____.
minor modification
_____ are approved directly by the authorities.
Major modifications
______ may be either approved directly by the authorities (or by an organization entitled for approval), or, indirectly though an approved procedure of the authorities granted to an organization holding a design approval
Minor modifications
Tasks typically performed during evaluation of a modification are as follows:
- A review of the installation plan and wiring.
- Verification of the presence of labels.
- Evaluation of the structural installation.
- A safety analysis.
- Evaluation of the conditions equipment/aircraft environment.
- Structural justifications.
- A written evaluation of electrical aspects of repair.
- A statement/analysis of the effect of the modification on weight and balance
_______ may be needed to ensure the modification performs as designed. These are performed by the applicant with or without participation of the authorities. The modifications being discussed are primarily for use in the issuance of a manufacturer’s Service Bulletin (SB), an Airworthiness Directive (AD), an Engineering Order (EO) or a Modification
Ground tests and or flight tests
A ______ concerns minimum modifications which affect neither safety nor the operational status of the aircraft. Often it deals with the improvement of reliability. An Evaluation ____ is used for the evaluation of new materials. As with all ____, it must apply specifically to the aircraft in question and performed within the parameters stated in the _____.
Service Bulletin (SB)
______ are also issued by manufacturers. These are not subject to approval by the authorities. They pre-warn operators of possible problems and how to cure them or reference changes for spare parts.
Service Letters, Service Information Letters (SL/SIL)
An ______ is a notification to owners and operators of certified aircraft that a known safety deficiency with a particular model of aircraft, engine, avionics or other system exists and must be corrected. If a certified aircraft has outstanding
_______ that have not been complied with, the aircraft is not considered airworthy. Thus, it is mandatory for an aircraft operator to comply with an _____.
Airworthiness Directive (AD)
The purpose of an AD is to notify aircraft owners:
- That the aircraft may have an unsafe condition, or
- That the aircraft may not be in conformity with its basis of certification or of other conditions that affect the aircraft’s airworthiness, or
- That there are mandatory actions that must be carried out to ensure continued safe operation, or
- That, in some urgent cases, the aircraft must not be flown until a corrective action plan is designed and carried out
An ____ may be of an emergency nature and require immediate compliance or it may specified an amount of time within which the ____ must be performed in order to stay in compliance.
