FAQ n.19042

What does the term “detailed maintenance records” mean?


“Detailed maintenance records” are those records required to be kept by the owner/operator to be able to determine the continuing airworthiness and configuration of the aircraft in accordance with part-M relevant for future maintenance. These are different from the detailed maintenance records required to be kept by a maintenance organisation as per M.A.614 or 145.A.55(c). Whereas maintenance organisations are required to retain all detailed records to demonstrate that they worked in compliance with their respective requirements, aircraft owners/operators need to retain those records required for assessing the aircraft configuration and the airworthiness of the aircraft and all components installed. ‘Dirty finger prints’ may not need to be transferred from the maintenance organisation to the aircraft owner/operator.

Where the maintenance organisation retains the detailed maintenance records in accordance with 145.A.55(c) and M.A.614, the owner/operator should receive the aircraft release to service of the maintenance performed  and all information necessary to determine the aircraft continuing airworthiness and its configuration, which includes references to all:

  • References to taskcards,
  • Information and substantiating data on modifications,
  • Airworthiness directives,
  • Information and substantiating data on repaired and non-repaired damage, and measurements relating to defects.
