7.20 Flashcards
What is the AMP ( approved maintenance program approved by ?
National authority ( EASA, FAA ) etc
What is the AMP ( aircraft maintenance program ) required to obtain ?
TC ( type certificate )
Can an operator customise the AMP ?
Yes and has o be approved by national authority
Who prepares and issues work cards ?
Planning department of the operator.
Who is the maintenance steering group formed from ?
Members of the ISC
What is the certification maintenance requirement ( CMR ) ?
It’s a Scheduled maintenance task made during the design certification of aircraft systems.
How is a CMR identified ?
Hashtag sign placed on task.
What’s the two types of CMR tasks and how are they different ?
One star CMR, cannot be changed and are mandatory
Two star CMR, can be changed.
What are airworthiness limitations ( AWL )?
Items that are classed as critical from fatigue or damage tolerance.
( inspection should be treated the same as a CMR one star task )
What’s a check cycle ?
Schedule of maintenance checks designed to ensure the continuing airworthiness of the aircraft.
( short haul fights have many check cycles a day as they complete several flights a day, however a long haul aircraft only has a few cycles due to only flying once or twice a day. )
Describe an aircraft’s A check ?
Performed every 500-800 flight hours and consists of a thorough visual inspection
Describe an aircraft’s C check ?
- Performed every 15 - 24 months
- detailed inspection of majority of the aircraft
( airframe, engines etc ) - calibration of flight controls
Describe an aircraft’s D check ?
- happened every 5-6 years ( which can be reduced )
- everything in aircraft is dismantled.
Where does the modification come from ?
- TC ( Type certificate ) holder.
- organisation.
( must take place under part 21 )
What will happen if the aircraft’s modification request is denied ?
Certificate of Airworthiness becomes invalid
What’s the two types of modification ?
Minor - doesn’t effect the aircraft’s mass or structural strength etc
Major - opposite to minor
What does the civil modification record hold ?
Record of modifications carried out by the organisation.
What’s a airworthiness directive ( AD ) ?
Released by EASA when it’s decided that a particular maintenance action is required to ensure the continued airworthiness of a specific aircraft.
What’s an emergency airworthiness directive ( EAD ) ?
Same as AD but the message to the operators with the infected aircraft has to get the message urgent.
What’s a service bulletin (SB) ?
Sent to operators informing them of concerns relating to a system affecting the aircraft safety which requires an immediate modification.
( often accompanied by a AD )
Who is responsible for making sure that all stores procedures are adequate ?
Quality assurance.
What’s the 2 store systems
Quarantine store
Bonded store
Explain bonded store ?
Comes after quarantine store,
Holds the items until they’re required for use.
Who attaches the Stores release notes ( SRN ) and goods release notes ( GRN ) ?
Quarantine stores.
Who retains the unacceptable certificates of an item ?
Co-signer
What must happen to the certificate on an item once it enters stores ?
Must be duplicated.
( every certificate must show printed serial number and be issued consecutively. )
What must happen to the certificate on an item once it enters stores ?
Must be duplicated.
What’s a EASA form-1 used to release ?
Parts and materials
( NOT AIRCRAFT )
Whats block 13a - 13e used for ?
Manufacture
Whats block 14a - 14e used for ?
Maintenance organisation.
Whats block 12 used for ?
Describes work identified
Who’s responsible to ensure all the relevant info is correctly recorded in the aircraft documents when the item is taken from stores ?
Engineer
Explain quarantine store ?
Holds items which aren’t yet approved with a form 1.
Who can issue / sign the CRS ?
LAE
( regulations governing an aircraft’s release to service a found in implementing rules (IR)
Whats the minimum age of a LAE with CRS capability’s ?
21 yrs
( must be able to produce their certificat of authorisation within 24 hours of it being requested by an authorised person )
If your aircraft is stranded in an area with no part-145 maintenance organisation, who has the authorisation to perform maintenance ?
Any person holding correct licenses with more than 3 Years maintenance experience.
Can the CRS summarise the maintenance performed when large amounts of maintenance has been carried out ?
Yes but has to have a cross reference to the work pack containing full details of the work carried out.
What regulation describes the legal requirements for crew licensing, mass and balance and data ?
Commission regulation
Who approves an aircraft’s tech log ?
National authority.
( technical logbook includes complete maintenance history of the aircraft. )
How long is the maintenance history kept in an aircraft’s technical logbook ?
Forever.
Who prepares the MMEL ?
Manufacture.
Whats information does the MMEL list ?
Lists equipment that can be temporary inoperative whilst maintaining an acceptable level of safety and airworthiness.
Who prepares the MEL ?
Operator
Who prepares the MEL ?
Operator
Which list is more restrictive MMEL or MEL ?
MEL
How many categories are there in the MMEL and MEL ?
4
What two lists does the dispatch deviation guide ( DDG ) contain ?
MEL and CDL
What does a DDG identify ?
External components which may be missing for a flight.
Whats the three areas quality management responsibility’s can be divided into ?
Quality assurance
Quality control
Quality improvement
What the two parts to a quality system ?
Independent audits
Quality feedback reporting system.
How long should records of an aircraft’s maintenance/inspection be kept for ?
3 years
Which maintenance staff carry out the maintenance on the defects logged on the technical logbook ?
Line maintenance
What are components which are not damage tolerant called ?
Life limited parts.
( means an inspection wouldn’t detect the impending failure. )
( fatigue life is less than than others on the aircraft )
What section in continued airworthiness is the the life limited parts document found in ?
Airworthiness limitations
Who approves the safe life airworthiness limitation items ?
EASA
