One Piece windshield
There was an STC by Aircraft Windshield Company. They will still sell you one after they make it special order. The guy who owned it with them (maybe he owned the company? I can’t remember) died and they no longer support it. So it’s back to a field approval only. Looks like from others experience over on the ISC forum, it’ll be twice as expensive to buy the one piece than to buy both halves…. At least that was all the case in 2016.
Aircraft Windshield Company is where I got mine but the paperwork I got still required a field approval. It only took about 15 min. The GADO at YIP is on the field so it was easily done. My IA does a lot of field approvals so the FAA was used to working with him. The approval was done in 1992 so an STC could have been created after that.
Jason Tadpole Tepool I bought one in 2016 new. It took a lot of persuasion to do so. My plane has had a one piece for a couple decades, back when Aircraft Windshield made, marketed and sold them regularly. So in my rebuild I wanted to get a new one…and fix the crack in the old one and sell it used. I called them and they said they won’t make them since there is no STC and they don’t want to get caught in the middle of any issues with the FAA. I told them I already have one approved by the FAA and installed, but I wanted to replace the part….no issues or risk. I provided them all my paperwork and logbook entries, and photos, and they finally agreed to make one for me. I got the impression they really didn’t want me to tell anyone about it either, but honestly, for my plane with it already approved, it’s no issue. I paid $798 in March of 2016.
