Another Inner Gear door thread (M20K/231)

[Austintatious]

OK, I am on a mission...  The reason is of little consequence, but lets just say that I want every bit of speed and efficiency the airplanes can get and AFAIK, you cant just go removing parts off an airplane without a CDL... So I want the parts that are supposed to be on my airplane to be on my airplane.

Both our M20K rockets at one point, FOR SURE had the plastic fairings behind the main gear wells.  I know this two ways... On one of them, I WATCHED as the mechanic removed the broken and shattered ones AND the rivet holes are still there .  On the other, The holes for the rivets are present in the shape of the fairing flange.

Now, As I understand it, there would be no reason for these fairings to be installed if there were no smaller inner gear doors installed, as it is the small inner gear doors that actually fair up against the aft fairing.  So, that brings me to those inner gear doors.

I can find NO reference to an M20K of the 231 variety having those smaller inner gear doors. The ones that attach just outboard of the tire... I cannot find part numbers for these doors. I cannot find diagrams for the MOUNTING hardware for these doors.

So, Before I go bugging people that are trying to work for a living and pay their bills, can anyone send me in the right direction to get my hands on these doors AND the mounting hardware for them?

This is for an M20K (NOT J) a 231.... the 252 is completely different.

Manual #235?

And that's essentially the same as the J model door, so that's a potential reference as well.

I've had them replaced on my K.  Here are the part numbers:

LHS: 550060-001
RHS: 550060-002

Lasar has (had) them, but I got them from wentworth for $500 a pop.

Wow, I have a pair of new ones. A friend just gave them to me. I used one of them when I had a bird strike on one of them. The bird was inside it. For $500, I would have just made a new one. I still have the busted one with the bird hole in it.

Lasar was charging more than double that at the time, $1200 I believe. I can make spaghetti and mow a lawn, but I definitely don't have the skills or equipment to make a gear door (or any door for that matter) :-), so $500 seemed reasonable.

Very reasonable, indeed. I managed to mangle one inner gear door on my Bravo and repacement is $1,800 from Mooney. At least it is available.

Was that for the gear doors? I should have looked up the numbers. I have the fiberglass fairings that go behind the gear doors.

I actually have a set of spare lower gear doors too, that someone gave me for free. They are in worse shape then the ones on the plane. I'm keeping them for patterns, if I decide to make new ones.

An A&P I used to work with retired and gave me his stash of Mooney parts. He also sold me all the gear puck tools for cheap.

If you need a set of inner doors, I can put you in touch with a shop here that’s got a few sets. They’re from J models, but should be the same.

That's good to know.
