ED Decision 2023/013/R
MAINTENANCE ACTIVITIES
Point 21L.A.124(e) requires the declared production organisation to have procedures that cover maintenance activities for new aircraft it has manufactured, as necessary to keep them in an airworthy condition. The declared production organisation shall not maintain newly manufactured aircraft beyond the point at which the applicable operational rules require maintenance to be performed by an approved maintenance organisation (point 21L.A.126(e)). If the declared production organisation intends to maintain aircraft beyond that point, it would have to apply for and obtain an appropriate maintenance approval (see Articles 3 and 4 of Regulation (EU) No 1321/2014).
MAINTENANCE OF AIRCRAFT
Examples of maintenance activities within the scope of work of a declared production organisation are:
— preservation, periodic inspection visits, etc.;
— embodiment of a service bulletin (SB);
— application of airworthiness directives;
— repairs;
— maintenance tasks resulting from special flights; and
— maintenance tasks to maintain airworthiness during flight training, demo flights and other non-revenue flights.
Any package of maintenance activities should be recorded in the aircraft logbook. It should be signed by certifying staff for attesting the conformity of the maintenance work with the applicable airworthiness data.
If the aircraft logbook is not available or if the production organisation prefers to use a separate form (for instance, for a large work package or for delivery of the aircraft to the customer), the production organisation should use EASA Form 53B which should subsequently become part of the aircraft maintenance records.
MAINTENANCE OF COMPONENTS OUTSIDE THE DPO CAPABILITY
Such a maintenance activity outside the capability of the aircraft declared production organisation may still be accomplished under the original release organisation. In such circumstances, the engine(s), propeller(s), parts and appliances will require re-release in accordance with point 21.A.163(c) or point 21L.A.126(c) (EASA Form 1).
Guidance on maintenance by declared production organisations: scope limits, logbook/EASA Form 53B recording, certifying staff signature, and re-release of components via EASA Form 1.
