2 CAAP 42M-2(0): Reliability programs July 2001 1.1 The overall maintenance program development process has two distinct processes within it. The initial maintenance program development (baseline) is the actual preparation of the aircraft maintenance specifications, and the reliability analysis (living process) collects data associated with the aircraft operating on the maintenance program. This process then measures the effectiveness of those maintenance tasks by alerting to systems, components and structures whose performance digresses from their expected levels. 1.2 A reliability program has two basic functions. Firstly, by means of the statistical reliability element, to provide a summary of aircraft fleet reliability and thus reflect the effectiveness of the way in which maintenance is being done. Secondly, to provide significant and timely technical information by which improvement of reliability may be achieved through changes to the program or to the practices for implementing it. Actions resulting from a reliability program may be to escalate or de-escalate, delete or add maintenance tasks, as necessary. This amendment will involve the approval of the Authority unless the operator has been approved to amend the maintenance program without direct involvement of the Authority. In simpler words, a reliability program enhances safety of flight operation and optimises maintenance costs. 2.1
