Hi. I think I do have a couple pics of the doors. I am new to the site. I will round them up and post them tomorrow. Am now proud owner of 1.5 ea. M20A Mooney. I owned this one back in the 80's, begrudgingly sold it in 1990, I loved the way it flew, it had no trouble getting me away from a Cessna I owned. Now, I just found it again and bought it back. It has gone through a couple changes. One of which is the gear doors. Just prior to selling it in 1990, I had to remove damaged fiberglass "scoop" doors and install the "overlappers" I got from LASAR, because at the time that is what I could obtain. The interim owners then had an incident in a small central Utah town and the mechanics had found some original 'glass scoop" doors=, but installed them backward so the scoops faced rearward (because they looked "better" or more proper that way?). they had guessed on the bridge attach points. Of course, "wrong way" there is an interference with the wheel suspension when retracted, so they cut out a small section and glassed in a bulge there. I can't stand it, I turned them back around and they fit just fine now. Adjusted, swung the gear, all good. But I just gotta know---what is up with that effective scoop they create when retracted? It has to have a purpose. I have an idea it scavenges out any vapors under the floor and maybe slightly pressurizes the cabin, but I think that would have the negative of keeping the floor pretty cold at altitude as well.
Any Ideas or input from Mooney Engineering historians? PLease, I am all ears.
