Each aircraft has to be maintained in accordance with a maintenance programme. With the maintenance programme, the continuous airworthiness of an aircraft is ensured. The responsibility for the airworthiness of the aircraft lays with the aircraft owner. Depending on the approval, we separate the maintenance programs for ML aircraft and non-ML aircraft. The definition of ML aircraft is set out in point ML.1 (a) of Annex VI to Commission Regulation (EU) No 1321/2014.
The CAA must approve the initial release of the maintenance programme and any subsequent amendments to it. If the continuing airworthiness of the aircraft is managed by CAMO or CAO, the maintenance program and its amendments may be approved indirectly by CAMO or CAO if this organization is granted the indirect approval privilege.
Documents Required for CAA's Maintenance Programme approval:
Application for Maintenance programme approval
Maintenance programme subjected to the application (one copy)
Maintenance programme checklist
The ML aircraft maintenance program shall be approved by the CAMO or CAO continuing airworthiness organization or declared by the owner if the continuing airworthiness is not managed by the CAMO or CAO. The ML aircraft maintenance program may be designed on the basis of the template EASA Form AMP (VZO-31) [ref .: AMC2 ML.A.302)]. CAA does not approve maintenance programs for ML aircrafts.
For ML aircraft maintenance programs, minimum inspection programs may be used:
Minimum Inspection Programme task/inspection checklist/worksheet (aeroplanes of 2730 kg MTOM and below)
Minimum Inspection Programme task/inspection checklist/worksheet (ELA2 sailplanes and ELA2 powered sailplanes)
Minimum Inspection Programme task/inspection checklist/worksheet (ELA2 hot-air balloons)
For rotorplanes and airships, minimum inspection is not possible.
Lycoming and Continental piston engines life-time extension
Life-time of Lycoming and Continental piston engines could be extended in accordance with Operational-Technical requirement for Lycoming and Continental piston engines recommended life-time extension.
In accordance with Article 3 of this Operational-Technical requirement, the CAA publishes (2 appendices):
Annex I: List of parameters for engine condition monitoring
Annex II: Engine parameters record form
