I am not familiar with the “safety clip” referenced in the accident report. The latch on my bird is pretty much bomb proof. The only benefit I can see to locking it before flight is that it forces the pilot to make sure that the latch is closed. How much does your latch stick out? Mine probably isn't totally flat, it sticks up maybe 1/16th of an inch. Do.. I have.. a bad "safety clip", I worry? :-| Quote Link to comment Share on other sites More sharing options...

I have.. a bad "safety clip", I worry? :-| I can’t speak to the K models. The vintage bids have a thin steel lever that sits flush against the the door when closed. It has a slight curve at the tail of the lever so one can get a finger tip under it pry it open. This is an image of a salvage door, but it’s identical to mine. In the position depicted the latch is locked over center. If you pushed on either of the latch pins it would only push the internal mechanism further over center latched position. It requires a fair amount of effort to open. It’s not difficult but definitely potential for the fairer sex to brake a nail. Like any over-center link design, the initial pull through center requires more effort. It’s been absolutely bullet proof. Any baggage door mishaps have been pilot induced. Over the years Mooney spent a significant amount of energy refining components of the M20 airframe…not all of them were improved with refinement…indeed sometimes simplicity and reliability was sacrificed.

So this is how it ends I was thinking. I called my A&P and he just happened to be around the corner. I handed him the key through the tiny window and he unlocked the door. Apparently the lock cylinder had turned in flight and locked the door from the outside. I’m guessing it’s time to remove it and take it to a locksmith? Lol If you don't have one, it's not hard to add an inside release to the cargo hatch. There are a couple threads here on how to do it and a couple of very old magazine articles on it as well. It was one of the first things I did when I got my airframe mechanic rating. Quote Link to comment Share on other sites More sharing options...

201Mooniac Posted May 31 Report Share Posted May 31 23 hours ago, Shadrach said: The door window is secured with 18 machine screws and lock nuts that hold down 9 rectangular aluminum plates that sandwich the window against at least 1" of of overlapping door skin to which it is glued. I'm not saying you could not break it, but it is not going to be easy, mostly because it will flex, distributing and absorbing the energy from a kick I'm sorry I wasn't clear when I wrote that, I agree with you completely, when I said side window I was thinking pilot side, I wouldn't try to break out the window from the door. Thanks for making that clear. Quote Link to comment Share on other sites More sharing options...
Shadrach Posted May 31 Report Share Posted May 31 18 hours ago, natdm said: That's more flush than mine, by a hair. I was at the hangar this morning and did some experimenting with the latch. I previously thought that pushing on the latch pins would just push the mechanism further over center making it impossible to push them into the retracted position. I was wrong. The pins can be pushed back into the retracted position. However, it takes considerable effort...in excess of 10lbs of pressure at a precise vector to push them in with the door open. With it closed, you would also have the friction from the striker plate acting on the sides of the latch pins. It's just not going to happen in any conceivable scenario other than a very unlikely mechanical/maintenance failure. I will confidently continue to leave my baggage door unlocked in flight to ensure that it remains available as an emergency exit. 1 Quote Link to comment Share on other sites More sharing options...

Since then, I’ve wondered how hard it would be to kick the door open if necessary. Wouldn’t it be easier, and a whole lot less expensive, to go out through the baggage door?

Pinecone Posted May 31 Report Share Posted May 31 Could always get a canopy breaker tool. Not the little hammer thing for cars, but the one the USAF had to get through a fighter canopy Here is a civilian version https://flyboyaccessories.com/products/chisel-style-canopy-breaker Quote Link to comment Share on other sites More sharing options...

I do not wish to cast aspersions on emergency personnel. They have a job to do and mostly they do it very well, but in our fly-in community when 911 was called by an overzealous resident for minor incidents, the emergency personnel did a lot of damage to the aircraft. Unless it was a life threatening situation, I would not call 911. Quote Link to comment Share on other sites More sharing options...

If you had to, I think you could just kick the door midway between the rotating handle and where the locking pin goes through the door frame. The latch pin doesn't stick that far into the door frame and it's not that robust. Betcha everything would flex and the door would open fairly easily. Not gonna try it though. :> Quote Link to comment Share on other sites More sharing options...

I know people like to toss around high heat and humidity numbers to make a point, but 100° and 80% RH requires a dew point higher than any dew point ever recorded in the US.

Joe Larussa Posted June 2 Author Report Share Posted June 2 So problem solved. So when unlocking the door it doesn’t take much of a turn to unlock the door and remove the key. If you don’t turn it a full 180 degrees the cylinder can turn back and lock. Glad it was a cheap fix, and now I understand my plane on a whole new level.

Lol That’s real good to know as mine is just like yours (no baggage door release). Only I usually have 2 eight year olds and my wife in there with me, and even if we’re not in sweltering heat, that’s gonna be some serious torture!

I noticed you were in GA. Heck 100 degrees in dry AZ in the summer would get me out of the cabin quickly. Quote Link to comment Share on other sites More sharing options...
