Essay: technical reliability program for aircraft maintenance

advice for all.

Technical Reliability (as opposed to dispatch reliability) of an airline is managed by the CAMO (Part 42)or maintenance controller as part of the “approved system of Maintenance” (or approved maintenance program), as indicated in the question.

In the hypothetical situation of you heading up the CAMO, reliability becomes your responsibility and you need to convince CASA (and me) that your system meets the requirements. So tell me how it works to deliver “good” technical reliability.

I would have expected you to find the “written” requirements in CASA, however, for your information Part 42 Manual of Standards and Advisory Circular 42-3 can be accessed for this purpose.

“Aspects” of Reliability have appeared in many of the module/lectures so reliability touches much of HES2935 subject material. It is covered to some depth in the above-referenced documents.

  • You will identify the objectives and required outcomes of your “Technical” Reliability Program.
  • You will identify just how you will structure and manage the program to deliver the required reliability of the fleet. (A description of the plan may help here)
  • You will comment on what level of reliability you want to achieve and the reasons / considerations for your choice in terms of

(a) The commercial requirements of an airline and

(b) The regulatory requirements of CASA, FAA etc.
