Application for document approval (air operations)

Operators that hold an Air Operator Certificate (AOC) must submit their operating manual (OM) to the competent authority for prior approval. This approval is required when amendments to the manual in question apply to procedures pertaining to the list of items that require prior approval (see requirement ORO.GEN.130 of Annex III of Regulation (EU) No 965/2012).

The Minimum Equipment Lists (MEL) in Part B of the operating manual require prior approval for every amendment, as stipulated in paragraph ORO.MLR.105 of Annex III of Regulation (EU) No 965/2012.

In addition, the key management system processes must be described and documented in accordance with requirement ORO.GEN.200 of Annex III of Regulation (EU) No 965/2012. This description may appear:

  • either in the operating manual (OMA);
  • or in a specific manual:
    • Organisation Management Manual (OMM);
    • Management System Manual (MSM);
    • Safety Management Manual (SMM);
    • Compliance Monitoring Manual (CMM).

When amendments to the manual in question apply to procedures pertaining to the list of items that require prior approval (see requirement ORO.GEN.130 of Annex III of Regulation (EU) No 965/2012), they must be submitted for approval in accordance with this procedure.
