Hello all, the latest electric compressor is approved by an AMOC (Alternate Method Of Compliance) in the late 1990s to address the AD. These pumps were tested in a lab using many different failure modes and various environments to FAA standards and FAA witnessing.
Hundreds, if not thousands have been sold over the past 30+ years. Very, very few failures have occurred which have required replacement.
I'm an airplane owner as well and I get it. Cheap alternatives are enticing.
However, we have costs of doing business as it relates to FAA PMA, inspections, paperwork, liabilities, safety, insurance and etc. Any business owner understands that there is a cheap way and a right way especially when working in a highly regulated industry like aviation.
Many times, I see Bob Fields Inflatable Door Seal listed as an upgraded STC when selling an airplane. An unapproved modified door seal is not.
To each their own.
Wishing everyone blue skies and safe flying!
Tom
