Continuing Airworthiness management

European Union Regulation n° 2042/2003

The European Union regulation n° 2042/2003, dealing with continuing airworthiness of aircrafts, was published on November 20th, 2003.

It establishes technical requirements and administrative procedures for aircrafts registered in the EU, or used by an operator for which a EU state oversees operations. Owners or operators must apply the regulation on September 28th, 2009 at the latest.

Continuing airworthiness tasks can be done in house or subcontracted to an approved Continuing Airworthiness Management Organisation (CAMO). CAMO approval is defined in a subpart of the regulation: CAMO are also known as “Part M subpart G” organisations.

Continuing airworthiness

Subpart C of the regulation establishes the requirements for continuing airworthiness. It describes the mandatory tasks, the usage of an approved maintenance programme, the application of Airworthiness Directives (AD), and the management of modification and repairs.

The continuing airworthiness record system is described in great detail. The records must include:

  1. The status of Airworthiness Directives;
  2. The status of modifications and repairs;
  3. The status of compliance with the Maintenance Programme;
  4. The status of service life limited components;
  5. The mass and balance report;
  6. The list of deferred maintenance.

Responsibilities and time constraints are specified. For example, total time and flight cycles of the aircraft and life limited components must be kept at least 12 months after the aircraft or component has been withdrawn from service.

Contracting continuing airworthiness

Owners or operators can contract with an approved CAMO in writing. The arrangement identifies the parties and the aircraft.
