Over the last couple of years, I have inquired on this forum about upgrades which would require a "Field Approval" with an FAA Form 337. Explicitly, "has anyone done this and is there a copy of a F337 which could be used as 'appropriate data' for a current project by ABS memebers?"...
Well, the response has not been very good and when I inquired with our ABS tech guys, they said, "sorry, not many of our members submit F337s to us!". I realize that we all have our own lives and issues which preclude digging around for some obscure paperwork, BUT there is a solution.
Our nice FAA, will for a nominal fee, $5 +/-, create a CD of all the offical records for your aircraft... Financial transactions, registrations, F337s, everything in their files! If you got one, for $5, you would have the most up to date data for YOUR aircaft. Not only would you know the financial and registration history of YOUR aircraft, but you would also know the history of modifications and possible damage history... You would also have a copy of any F337 filed for your aircraft. Nice to know; Nice to share...
OK, so if you have made modifications to your aircraft over the years, which were NOT STC installations and required a "field approval" and the subsequient filing of an F337, then there is a wealth of information out there which is not currently avialable to ABS memebers... The point of this post is: "Your info can help me; my info can help you!"
I promise to submit my latest F337s (AeroFlash wingtip strobes, PMA but not STC, which piggyback on existing Grimes E position lights (NOT Whelen STC, NOT $700, only $300), additional MLG Safety Switch (per Lew Gage), and replacement of Grimes mechanical rotating beacon with Universal FS-4400 strobe beacon; all of which were completed recently during an annual.
OK, end of rant for now. Please consider checking your records and submiting anything you have.
