Summary of Aviation maintenance management

Aviation maintenance management

- Maintenance facility “part 145” – such as KLM and JET SUPPORT
- Airline mx maintenance organization “part M” – such as Arke Fly and KLM
- Prod. & Design organization “part 21” – such as Boeing and Fokker




European Parlement responsible for

Aircraft airworthiness – an aircraft is required to be in an airworthy state in order to perform a
flight.

Certificate of airworthiness CofA - in respect of an aeronautical product, means in a fit and
safe state for flight and in conformity with its type design; Source: CAR 101.01, Subpart 1 -
Interpretation Content last revised: 2007/12/30

To remain in an airworthy state all requirements for maintenance, repair and alterations are
performed according to the regulations.

The owner of the aircraft is responsible for the continuing airworthiness and shall ensure that
no flight takes place unless:

1) The aircraft is maintained in an airworthy condition
2) Any operational and emergency equipment fitted is correctly installed and
serviceable or clearly identified as unserviceable
3) The airworthiness certificate remains valid
4) The maintenance of the aircraft is performed in accordance with the approved
maintenance programme as specified in M.A.302

,Part M maintenance
The owner is reponsible for the airworthiness of the aircraft.

- Operator maintenance program
- Planning of maintenance
- Aircraft technical log (AFL, HIL, ACL)
- Maintenance data (AMMM, WDM, IPC, SRM, Part-21 data)
- Maintenance records
- ARC inspections

Limited to pre-flight inspections
Activities who needs a “Release to Service” carried out by a part-145 AMO
Contracted maintenance data
Monitoring of contracted work.




CAMO organisation, MACRO perspective

, The CAME shows how the CAMO complies to Part M

➔ CAMO describes:

Part 0 – general description of company, incl. personnel & responsibilities.

Part 1 – airworthiness management procedures.

Part 2 – Quality system.

Part 3 – contracted maintenance.

Part 4 – Airworthiness review procedures.

Minimum tasks performed by the CAMO organisation


➔ Tracking of aircraft data

➔ Analysis of maintenance program (AMP) effectiveness

Such as: Reliability data, defects, Mx cost, change in operation, crew feedback and
GWK feedback

Action: Revised AMP

➔ Embodiment policy of non-mandatory modifications (SB’s)




➔ Reliability program (mandatory)

Such as: component removals, pilot reports, maintenance reports and incidents.

Action: AMP, instructions, one-time inspection, modifications.

➔ Management of maintenance program

➔ Control and accomplishment of airworthiness directives (AD’s)

➔ Major modification standards

➔ Defect reports / fault management (incl. incidents or occurrences)

➔ Engineering activities (design part 21)

➔ Reliability program (removals, defects, trends)

➔ Pre-flight check/ weighing / check flight procedures
