More Research on "The great center strap debate"

[Pushpull5785]

Actually been a member and lurked for years. I’m just curious about this as I’m doing my windows here shortly.

I did say that if you find an IA willing to sign it off without the STC then go for it.

I personally would rather pay the $600 (maybe because my IA will not install the windshield without either reinstalling the center post or obtaining the STC… in his words, if I take it off, it goes back on. If not there better be paperwork) that being said Im still not sure which way I’ll go as I do not necessarily mind the center post and it saves me from getting a new compass… which would cost me more money.

Also Id assume RTAerospace has an account on here don't they? Has anyone reached out to them?

Here is a photo of a 337B that was for sale jan/2021
Looks like he did without posts or plates.
Was it legal? idk.
I do remember reading somewhere the concern was that the windshield would/could pop out during flight.
but i think OEM wind shields were 1/8” thick at the time but now they are available in 1/4” and less likely to come out.

It sure does make the old girl look pretty good.

My center post was removed before I purchased the plane in 1995 (1977 337G). I know there is paperwork for the removal, I think a 337 form with some accompanying engineering data. I don’t think it was an STC.

I am not near the logbooks but will be so on Sunday.

I would be glad to either post them to the forum or email them to anyone who is interested.

No sense in going through the extra expense or re-inventing the wheel if it has been done previously and accepted by the FAA

I have located the paperwork for the windshield without stiffener. It is a 337 form, filed in 1991, which also contains FAA form 8110-3 approved by a Structural DER on 5/3/1991. I have copies of this 8110-3 form with an "Analysis of Removal of Windshield Frame Center Member" and some accompanying photographs (which didn't reproduce well).

If anyone wants a copy of this form I would be happy to email it to you. I am a little reluctant to just post it to the website.

Makes sense.

Could you send to me at email?

Bigcheese@potomac-airfield.com

I will be able to use w my next windshield replacement.

Why are you reluctant to post?
