ANNEX I - Continuing Airworthiness Requirements
of Annex Vb (Part-ML), as applicable.
(b) For every aircraft managed, the approved continuing airworthiness management
organisation shall:
1. ensure that an aircraft maintenance programme including any applicable reliability
programme, as required by point M.A.302 of this Annex (Part-M) or ML.A.302 of
Annex Vb (Part-ML), as applicable, is developed and controlled,
2. for aircraft not used by air carriers licensed in accordance with Regulation (EC) No
1008/2008, provide a copy of the aircraft maintenance programme to the owner or
operator responsible in accordance with point M.A.201 of this Annex (Part-M) or
ML.A.201 of Annex Vb (Part-ML), as applicable,
3. manage the approval of modification and repairs,
4. ensure that all maintenance is carried out in accordance with the approved
maintenance programme and released in accordance with Section A, Subpart H of
this Annex (Part-M) or Section A, Subpart H of Annex Vb (Part-ML), as applicable,
5. ensure that all applicable airworthiness directives and operational directives with a
continuing airworthiness impact, are applied,
6. ensure that all defects discovered during scheduled maintenance or reported are
corrected by an appropriately approved maintenance organisation,
7. ensure that the aircraft is taken to an appropriately approved maintenance
organisation whenever necessary,
8. coordinate scheduled maintenance, the application of airworthiness directives, the
replacement of service life limited parts, and component inspection to ensure the
work is carried out properly,
9. manage and archive all continuing airworthiness records and/or operator's technical
log.
10. ensure that the mass and balance statement reflects the current status of the
aircraft.
(c) In the case of complex motor-powered aircraft or aircraft used for CAT, or aircraft used for
commercial specialised operations or commercial ATO or commercial DTO operations,
when the CAMO is not appropriately approved in accordance with Annex II (Part-145) or
Subpart F of this Annex (Part-M) or Annex Vd (Part-CAO), the organisation shall, in
consultation with the operator, establish a written maintenance contract with an
organisation approved in accordance with Annex II (Part-145) or Subpart F of this Annex
(Part-M) or Annex Vd (Part-CAO) or with another operator, detailing the functions specified
under points M.A.301(b), M.A.301(c), M.A.301(f) and M.A.301(g) of this Annex (Part-M), or
points ML.A.301(b) to (e) of Annex Vb (Part-ML), ensuring that all maintenance is
ultimately carried out by a maintenance organisation approved in accordance with Annex II
(Part-145) or Subpart F of this Annex (Part-M) or Annex Vd (Part-CAO) and defining the
support of the quality functions referred to in point M.A.712(b) of this Annex (Part-M).
(d) Notwithstanding point (c), the contract may be in the form of individual work orders
addressed to the maintenance organisation approved in accordance with Annex II (Part-
145) or Subpart F of this Annex (Part-M) or Annex Vd (Part-CAO) in the case of:
1. an aircraft requiring unscheduled line maintenance;
2. component maintenance, including engine maintenance.
M.A.708 GM Continuing airworthiness management
The CAMO should have adequate knowledge of the design status (type specification, customer
options, airworthiness directives (ADs), airworthiness limitations contained in the aircraft instructions
for continuing airworthiness, modifications, major repairs, operational equipment) and of the required
and performed maintenance. The status of aircraft design and maintenance should be adequately
documented to support the performance of the quality system.
For CS-25 aeroplanes, adequate knowledge of the airworthiness limitations should cover those
contained in CS-25 Book 1, Appendix H, paragraph H25.4 and fuel tank system airworthiness
limitations including critical design configuration control limitations (CDCCL).
M.A.708(b)(3) AMC Continuing Airworthiness Management
When managing the approval of modifications or repairs the organisation should ensure that Critical
Design Configuration Control Limitations are taken into account.
M.A.708(b)(4) GM Continuing airworthiness management
This requirement means that the CAMO is responsible for determining what maintenance is required,
when it has to be performed, by whom and to what standard in order to ensure the continued
airworthiness of the aircraft.
M.A.708(c) AMC1 Continuing airworthiness management
1. In case of complex motor-powered aircraft, aircraft used for CAT operations, aircraft used
for commercial specialised operations and aircraft used by commercial ATO, the
provisions of M.A.201 establish that a CAMO is required. This CAMO is in charge of the
continuing airworthiness management and this includes the tasks specified in M.A.301
points (2), (3), (5) and (6). If the CAMO does not hold the appropriate maintenance
organisation approval, then the CAMO should conclude a contract with the appropriate
organisation(s).
2. The CAMO bears the responsibility for the airworthy condition of the aircraft for which it
performs the continuing airworthiness management. Thus, it should be satisfied before
the intended flight that all required maintenance has been properly carried out.
3. The CAMO should agree with the operator on the process to select a maintenance
organisation before concluding any contract with a maintenance organisation.
4. The fact that the CAMO has contracted a maintenance organisation approved under
