Frequently asked questions

In respect of M.A.201(f) and (g): Can an operator, even with CAMO approval, contract a third CAMO to carry out airworthiness management tasks?

Yes, regardless of owner/operator approvals and scope, you have the option to sign a contract with a CAMO. The important thing is that continued airworthiness is managed by an appropriate CAMO.

What is meant by “Detailed maintenance records”?

“Details of maintenance work performed” according to GM M.A.305(g) are the records that must be maintained by the person or organisation responsible for the continuing airworthiness of the aircraft in accordance with M.A.201 in order to be able to fulfil its obligations under Part M. They are only part of the records referred to in points CAO.A.090(a) or 145.A.55(a).
Maintenance organizations must keep all detailed records to demonstrate that they have worked in accordance with their respective requirements and procedures.
It is not necessary to transfer all records from the maintenance organisation to the person or organisation responsible for the continuing airworthiness of the aircraft in accordance with M.A.201, unless they specifically contain information relevant to the configuration of the aircraft and its future maintenance. Therefore, it is not necessary for the person or organisation responsible in accordance with M.A.201 to keep the certificates of conformity, the references to the batch numbers of the material used or the individual work cards verified and/or generated by the maintenance organisation. However, the owner/CAMO may request such information from the maintenance organisation to verify and demonstrate the effectiveness of the aircraft maintenance programme.
Information relevant to future maintenance may be contained in specific documents related to:

  • amendments;
  • airworthiness directives;
  • repaired and unrepaired damage;
  • components mentioned in M.A.305(d); and
  • measures relating to defects.
What is meant by “Subcontractor” from the point of view of checking the reliability and checking the health of the engine (reliability monitoring & engine health monitoring)?

As provided in point CAMO.A.125(d)(3), a CAMO may organise the performance of limited continuing airworthiness tasks with any subcontracted undertaking, working under its Management System, which shall be included in its certificate of approval (AC-CAMO-P01-F14).
Tasks that can be outsourced include reliability control and engine health control (reliability monitoring & engine health monitoring). 
However, when these tasks are entrusted to the manufacturers or owners of the aircraft or engine designs and their feedback is limited to reporting to CAMO the reading of the data provided, it will be considered as non-subcontracting and, therefore, will not be included in the CAMO approval certificate.
