It states that it is "PMA approved" - what does this mean and what is
required to get such an approval? It means that a federal bureaucrat has decided that the design and manufacturing system meet FAA standards, and thus the part can be sold as an aircraft component. Since the FAA standards are a bad joke, it doesn't mean the design and manufacturing system are actually adequate. The best (but not legal) solution would be to save the box, and to have someone with a clue build you a real inverter (it's not hard) and then seal the box up again. Michael |
