10.7 (a): Applicable National and International Requirements Flashcards
How and where are non-EASA aircraft defined?
Annex 1 of the Regulation 2018/1139
Non EASA aircraft means aircraft that are not subject to EASA reg such as state aircraft Military,police etc
What log books must be kept to assist in the maintenance of light aircraft?
Aircraft, Engine and Propeller Log books
As light aircraft require 50 hour. 100 hour checks and some calendar checks (6month 12 month) - each part is put in the applicable logbook and used as a running check to see what and when is due
What derogation is allowed for annual checks?
10%
If not CMR task, recurring AD’s etc.
What is understood by the phrase ‘safety critical maintenance tasks’?
System to avoid simultaneous incorrect maintenance on two or more safety critical systems. Done by:
1. Staggered Maintenance - IDG service one night, following night, other engine IDG service - note events must be separated by atleast one flight cycle
2. Separate Work teams - Both IDG’s serviced in one night but 2 different engineers/teams to do
3. If both IDGs serviced by one person same night - Additional inspections and functional checks should be performed independently to ensure system serviceability.
How must companies service safety critical systems to avoid compromising the redundancy of an aircraft’s systems?
System to avoid simultaneous incorrect maintenance on two or more safety critical systems. Done by:
1. Staggered Maintenance - IDG service one night, following night, other engine IDG service - note events must be separated by atleast one flight cycle
2. Separate Work teams - Both IDG’s serviced in one night but 2 different engineers/teams to do
3. If both IDGs serviced by one person same night - Additional inspections and functional checks should be performed independently to ensure system serviceability.
Maintenance personnel’s initial and continuation training should highlight the critical nature of conducting maintenance tasks on essential or primary systems. The instruction given should provide personnel with the necessary information to identify and satisfactorily accomplish such tasks.
Why does the pre-flight differ from all other maintenance inspections?
Pre-flight inspections are regulated in Part-M as a Continued Airworthiness task. It is not released to service by a CRS under Part-145.
Part-M states that the pilot or flight crew or nominated person may carry out the pre-flight check.
Who can issue an Airworthiness Directive?
'’ADs consist of particular airworthiness requirements which are mandatory for specific aircraft, engines and components. The ADs may be issued either by the national aviation authority of the state of the Type Certificate Holder (French Compotent authority), or by the national authority of the registered aircraft (IAA)
EASA can also issue ADs (even EADS - Emergency Airworthiness Directives)
When will an Airworthiness Directive be issued?
An Airworthiness Directive will be issued by EASA, IAA or country of design authority (France Airbus, USA Boeing) for mandatory airworthiness requirements for specific aircraft, engines and components.
When must an AD be complied with?
All ADs must be complied if you have the applicable aircraft as they are mandatory Airworthiness requirements.
What responsibility has an operator or Part-M CAMO got with respect to Non Mandatory Service Bulletins?
'’If a service bulletin is not an alert service bulletin or a bulletin referenced in an AD, it becomes optional and may or may not be incorporated by the operator’’
Service Bulletins (SB) are notices to aircraft operators from a manufacturer notifying them of a product improvement.
Alert service bulletins are issued by the manufacturer when a condition exists that the manufacturer feels is a safety related item as opposed to just a product improvement.
Note: SBs come from the manufacturer
Give 6 examples of commonly used Maintenance documentation?
IPC, TSM, WDM, CMM, MEL, AMM, SRM …
