Question 27

The term 'Maintenance Programme' is intended to include scheduled maintenance tasks, the associated procedures, and standard maintenance practices. The term 'Maintenance Schedule' is intended to embrace the scheduled maintenance tasks alone.

Question 27

Aircraft Maintenance Programme Maintenance of each aircraft shall be organised in accordance with an AMP. Every aircraft must be maintained in accordance with an AMP approved by the CAA. Where the airworthiness is managed by either a CAMO or CAO the organisation may approve the AMP and its amendments via an indirect approval procedure, which is an abbreviated process that requires less input from the CAA

Answer 27

The AMP must provide details of which maintenance activities must be carried out at what time. It must also demonstrate compliance with instructions issued by the CAA or type certificate holders, such as Airworthiness Directives (ADs) and Service Bulletins (SBs). For complex motor-powered aircraft, the AMP must include a reliability programme. The AMP is subject to periodic reviews which analyse data, such as faults found, to continually improve the AMP. This analysis could result in less frequent inspections if no faults are being found in a particular location

Question 27

The purpose of a reliability programme is to ensure that the aircraft maintenance programme tasks are effective and their periodicity is adequate. The reliability programme may result in the escalation or deletion of a maintenance task, as well as the de-escalation or addition of a maintenance task. A reliability programme provides an appropriate means of monitoring the effectiveness of the maintenance programme.

Question 27

Reliability programmes should be developed for aircraft maintenance programmes based upon maintenance steering group (MSG) logic or those that include condition monitored components or that do not contain overhaul time periods for all significant system components. Reliability programmes need not be developed for aircraft not considered complex motor- powered aircraft or that contain overhaul time periods for all significant aircraft system components.
