I think the real concern is " (you or) Your mechanic can determine it is a suitable part" as John said.
I have seen automotive oil pressure gauges with plastic NPT inlet fittings. You break a fitting over uninviting terrain and dump all your oil, was the $25 difference in price worth it? Then there is the hassel of getting a new IA to sign the next annual. Or selling to a new owner. FAA-PMA saves a lot of hassel, but as the gascolator story mentioned earlier, it is still no foolproof guarantee.

Like I am really worried if my non TSO or PMA gauge goes tits up and I have to replace it. There are many parts of my plane that I would only put on "approved" parts, and the best ones I can find (my constant orders to Skyport prove this). Sometimes it gets into making me feel like the FAA thinks I have no common sense. --- In [email protected], John Cooper <j...@...> wrote: > > On 6/8/2010 6:41 PM, heave...@... wrote: > > Meaning we can replace a faulty one with another SW gage.
