More Research on "The great center strap debate"
Comrades!
Never knowing when to leave anything alone, I felt need to 'drill down' on this topic a bit more. Yes, that IS a pun and I want full credit! Not sure if PDF got to forum, so here is link to it posted on my airfield website http://potomac-airfield.com/newslett...ldresearch.pdf Please eyeball the attached PDF and throw rocks at it if you feel the need. --- If you look back at decisions and actions made years ago, it seems 'THE STRAP' today really just boils down to a matter of personal preference. ....As long as you are NOT in a pressurized 337. Which is fine. I like freedom, don't you? Years ago, before cancer got him, a good personal friend and Potomac-based pilot Alfonso Diaz DC dug deeply on this 'behind the green (gov) door' (within FAA and NTSB). You may not have known this, but he had been an FAA flight safety inspector, as well as air traffic controller, lots of clearances, etc etc etc. He found ...no issues. Zip. Null. Zippo. Big goose egg. While there IS always the possibility 337 windows have been popping out all over the world, left and right, chances are at least one would have been reported somewhere. Zip. Null. Zippo. Big goose egg. He put a new windshield in his 336 ...and then hit a bird. He sent me photos. Yikes. To get the perspective of a well-known and widely trusted IA/ A&P, very familiar with these airframes, I got into this discussion with Mike Busch of Savvy Aviation. His reply in my report. As with most everything, today's practices are often just vague repetitions of the past, having entirely forgotten the rhyme or reason for those past decisions. Which may or may no longer apply at all... Enjoy

Thanks for the information. Was this a field approval by a DER, or DER generated tech data? If it’s tech data anyone can use it. If field approval than it only applies to that specific tail number. I know, some FAA rules are dumb.

Owning a P337H, going "strapless" is not an option for me.
However, in my previous life as a Beechcraft owner, every model I owned from Bonanzas, Travel Airs, Twin Bonanzas, and Barons ALL had their factory center strap removed and replaced with D'Shannon one-piece windshields. The only question was what thickness and tint color I desired. There was never an issue of airworthiness. I once had a birdstrike on the Baron one-piece windshield whilst on approach to FXE (Fort Lauderdale Executive) by a very large seagull. It cracked the windshield, but did not penetrate. My two cents.  Last edited by mshac : 07-18-22 at 01:16 PM.

Check out AC 43-210A.
The logic of a minor alteration is good…but since an STC exists for this alteration, it is considered a Major alteration by definition. It’s a kind of catch 22. This would make for a great legal challenge. Did the FAA erroneously issue an STC? An STC can not be granted for a minor alteration. But I like the statement (paraphrased) “…if you ask the FAA it’s out of your hands.”

STC RT Aero
I have seen pictures of that in the past.
What I recall was basically an excuse to charge someone $600? A little metal plate at the bottom of the windshield that is already solidly held in by the fairing. Really?
