Good Maintenance and Keeping Owners Happy

The AOPA Maintenance Working Group (WG) first met in October 2010 with one of the main objectives being to provide a forum for discussion of maintenance issues to the mutual benefit of aircraft owners and maintainers following the initial experience of both parties of EASA Part M. General Aviation for April 2011 carried an article describing the working group’s establishment and rationale in some detail.

Its Terms of Reference appear can be read here.

The WG also provided a convenient forum to air maintenance problems encountered by a small number of aircraft owners. These problems were those sufficiently vexatious for the owner to contact AOPA to seek help and in 2009 were running at about 30 per year. These have dropped significantly to more like 10 per year, possibly as a result of fewer hours being flown and possibly because of Part M itself. Considering that the 2 – 3000 aircraft owned or partly owned by AOPA members visit a maintainer for an annual or periodic regular check at least twice a year, the number of problems arising amounts to no more than a fraction of one percent. This clearly indicates a very high degree of owner satisfaction with their maintainer generally.

Nevertheless, the WG members decided it would be a good idea to draft a Code of Practice for Maintenance and Repair that they themselves follow and could be recommended to other light aircraft maintainers, especially in cases where aircraft change hands and the new owner transfers to a new maintainer. These light aircraft maintainer members are listed on the AOPA website. Then, if the new owner has had no previous dealings with the maintainer, the Code of Practice can be used to establish a basis for the maintenance organisation commitment to their customer future business relationship. 

When EASA Part M made its appearance on the maintenance scene, introducing new terms such as ‘CAMO’, several owners contacted AOPA asking for reader friendly explanations of the essential details, including the differences in maintenance procedures between Annex I and Annex II aircraft. One of the owner members of the WG, Brian Chambers, addressed this problem by producing this flow chart, which summarises the essential details and it is hoped that many AOPA owner members will find it helpful.
