1.7.1.4 The maintenance programme is a document which describes the specific maintenance tasks and their frequency of completion, necessary for the continued safe operation of those aircraft to which it applies.
1.7.1.5 A maintenance programme for each aircraft as required by Annex 6, Part I, Section 8.3 and Part III, Section II, 6.3 shall contain the following information:
a) maintenance tasks and the intervals at which these are to be performed, taking into account the anticipated utilisation of the aeroplane;
b) when applicable, a continuing structural integrity programme;
c) procedures for changing or deviating from a) and b) above; and
d) when applicable, condition monitoring and reliability programme descriptions for aircraft systems, components and power plants.
Note. — In the context of this paragraph, “when applicable” means that the condition monitoring and reliability programmes are only applicable to aircraft types where the maintenance programme was derived using the maintenance review board process (see Section 1.7 of Part III of this manual)
1.7.2 Maintenance programme approval
In accordance with the basic aviation law of the State, the DCA should be given the authority and responsibility for the approval of each operator’s maintenance programme — that is, the approval of the programme in which an operator establishes the time limitations (or standards for determining time limitations) for scheduled maintenance tasks for the aircraft (overhauls, inspections and checks of aircraft, engines and appliances and their monitoring).
1.7.3 Maintenance programme development basis
1.7.3.1 Operator's maintenance programmes should normally be based upon the manufacturer recommended instructions for continued airworthiness such as, but not limited to, the maintenance review board report (see Section 1.7 of Part III of this manual), where available, and the Type Certificate holder's maintenance planning document or Chapter 5 of the maintenance manual (i.e. the manufacturer's recommended maintenance programme). The structure and format of these maintenance instructions may be rewritten by the operator to better suit his operation and control of the particular maintenance programme.
1.7.3.2 For a newly type-certificated aircraft, where no previously approved maintenance programme exists, it will be necessary for the operator to comprehensively appraise the manufacturer's recommendations (and the MRB Report where applicable), together with other airworthiness information, in order to produce a realistic programme for approval.
1.7.3.3 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 operator will automatically be approved for another operator. Evaluation is to be made of aircraft/fleet utilisation, landing rate, equipment fit and, in particular, the experience of the maintenance organization should be assessed. Where the CAA is not satisfied that the proposed maintenance programme can be used as is by the operator, the CAA should request the operator to introduce appropriate changes to it, such as additional maintenance tasks or de-escalation of check frequencies, or to develop the aircraft initial maintenance programme based upon the manufacturer’s recommendations.
1.7.4. Updating the maintenance programme
1.7.4.1 Revisions to the approved programme should be raised by the operator, to reflect changes in the Type Certificate holder’s recommendations, modifications, service experience, or as required by the CAA. Reliability programmes form one important method of updating approved programmes.
1.7.4.2 The operator may only vary the periods prescribed by the programme with the approval of its CAA. The CAA should not approve intervals escalations or tasks modifications related to airworthiness directives (AD), airworthiness limitation (ALI) and certification maintenance requirements (CMR) without an appropriate consultation with the State of Design (see Section 1.6 of Part III of this manual).
