Part-M Appendix I to AMC M.A.302 and AMC M.B.301 (b)
1.1.14 If applicable, details of Critical Design Configuration Control Limitations
together with appropriate procedures.
1.1.15 If applicable a statement of the limit of validity in terms of total flight cycles/calendar date/flight hours for the structural programme in 1.1.13.
1.1.16 The periods at which overhauls and/or replacements by new or over-hauled components should be made.
1.1.17 A cross-reference to other documents approved by the Agency which con-tain the details of maintenance tasks related to mandatory life limitations, Certification Maintenance Requirements (CMR’s) and ADs.
Note: To prevent inadvertent variations to such tasks or intervals these items should not be included in the main portion of the maintenance programme document, or any planning control system, without specific identification of their mandatory status.
1.1.18 Details of, or cross-reference to, any required reliability programme or statistical methods of continuous Surveillance.
1.1.19 A statement that practices and procedures to satisfy the programme should be to the standards specified in the TC holder’s Maintenance Instructions. In the case of approved practices and procedures that differ, the statement should refer to them.
1.1.20 Each maintenance task quoted should be defined in a definition section of the programme.
Programme basis
2.1 An owner or an M.A Subpart G approved organisation’s aircraft maintenance programme should normally be based upon the MRB report, where applicable, and the TC holder’s maintenance planning document or Chapter 5 of the mainte-nance manual, (i.e. the manufacturer’s recommended maintenance programme).
The structure and format of these maintenance recommendations may be re-written by the owner or the M.A Subpart G approved organisation to better suit the operation and control of the particular maintenance programme.
2.2 For a newly type-certificated aircraft where no previously approved maintenance programme exists, it will be necessary for the owner or the M.A Subpart G approved organisation to comprehensively appraise the manufacturer’s recom-mendations (and the MRB report where applicable), together with other airwor-thiness information, in order to produce a realistic programme for approval.
2.3 For existing aircraft types it is permissible for the operator to make comparisons with maintenance programmes previously approved. It should not be assumed that a programme approved for one owner or the M.A Subpart G approved organisation would automatically be approved for another.
Evaluation should be made of the aircraft/fleet utilisation, landing rate, equip-ment fit and, in particular, the experience of the owner or the M.A Subpart G approved organisation when assessing an existing programme.
Where the competent authority is not satisfied that the proposed maintenance programme can be used as is, the competent authority should request appro-priate changes such as additional maintenance tasks or de-escalation of check frequencies as necessary.

2.4 Critical Design Configuration Control Limitations (CDCCL)
If CDCCL have been identified for the aircraft type by the TC/STC holder, mainte-nance instructions should be developed. CDCCL’s are characterised by features in an aircraft installation or component that should be retained during modifi-cation, change, repair, or scheduled maintenance for the operational life of the aircraft or applicable component or part
