1975 M20F CB solution rh fuel cap 431-21A
Sabremech replied to Jpravi8tor's topic in Vintage Mooneys (pre-J models)
Let’s see if the 337 will post here. Here’s what I did for my ( Hammdo’s now) Mooney. Scannable Document on May 2, 2022 at 6_56_13 PM.pdf -
1975 M20F CB solution rh fuel cap 431-21A

I have a mod I did to my C that put all new fuel caps and flanges in. I’ll post a copy of the 337 here tonight along with in the 337 archive thread. Might be an option for you. David -
I did exactly this when I sold my C model to Hammdo. I’m still heavily involved in aviation but now have little interest in flying anymore. I don’t have the mental want to anymore and the cost just reinforces it for me. Not looking back and enjoying other things in life. David

Hi Don, you might. If the square drive is turned and not in line with the tool mounting surface, I would. Let me look at what I may have. The right adapters are hard to find. Thanks, David
-
If it’s a click type ratcheting torque wrench, getting that exact happy spot is more difficult than a dial type with a second hand that stops when you do. I find I can focus on the movement then read what’s been recorded on the dial by the second needle. Mines not a ratcheting type so I need to have it positioned the way shown in the maintenance manual. Probably just a preference, but this is mine. Thanks, David
-
I have new tools available and am working provide the adapter for each of my tools until the next run and I rotate the square socket. Thanks, David
-
For the main gear, you can fill it up with fuel and / or have someone sit on the wing to compress them. Pretty easy that way. Nose takes the tool to get them compressed enough to re-install. I don’t think you can buy them directly from Lord, but doesn’t hurt to look and see if it’s an option now. David David

The cheek panels are mainly for inspection but I’ll also have the option for louvers in that panel for say the turbo charged airplanes for additional air flow. I hope that it’s an optical illusion! It’s also not sitting all the way together and not tight to to firewall flange. Thanks, David
-
Fitting continues. I feel as I have the front area solid now and am close to sending it back for the mold repair. Some final bodywork on my part and I’ll take it back for another set to be made. Baffling and induction systems to be worked on after I drop the cowling off. David
-
Hi Don, I’m not sure yet. I do have to make some of the baffling and can’t use all of the kit so I need to weigh out the cost versus me just making them all. Thanks, David
-
Engine mount and engine installed. Lower cowling clamped in place to study the fitting. David
-
I finished getting my new Mooney ( fuselage) up on its new gear today. Engine installation coming and then on to baffling and new cowling fitment for the mold repair. David
-
Good morning. I’ve been holding out on information so as to not seem to keep promising amid more delays. It’s looking up and I recently purchased a forward fuselage section so I can build up baffling sets along with fit cowlings as much as possible in my shop. Progress. Thanks, David

So you believe it’s ok to recommend deviating from maintenance manuals on a public forum? That’s the heart of the matter. Not a pissi*g contest at all.
-
Give it a rest. How long have you been an A&P? Afraid to put that out in public!
-
Nope, I understand quite well what you’re professing here and to the OP! How long have you been an A&P? Still waiting!
-
Yep, agreed. What I found most disturbing was the advice to an owner who’s not an A&P and didn’t know what travel boards are to deviate from the maintenance manual on a public forum. Thanks,
-
I’ll have to disagree once again. They are both quite useful. The travel boards reduce the risk for error. It’s interesting to note that travel boards are still widely used in the corporate aviation. I’ve had to rent them a few times over the years. Also quite nice to have them available for the Mooney as it made re-rigging stab trim a breeze.
-
Big point missed? Nope! Do post up how many years you’ve been an A&P!
-
Why do you advocate on a public forum for someone to not follow the maintenance manual procedures? You might use the PM feature for that kind of advice. The FAA along with Mooney monitor these boards and anything you post here may be used for an investigation. I do see from the FAA database you do hold that certificate. How long have you been an A&P? Good luck with pointing the FAA to your approved A&P school. I suspect with that attitude they’ll request you return for remedial training.
-
Who’s saying it’s an issue with the flaps? The OP doesn’t know what causing the problem. If there’s a fatal accident and it can be directly or indirectly attributed to improper rigging, you have no leg to stand on as the AP who did it without the correct tooling. Do it as you see fit, but it’s not IAW the maintenance manual procedure. I’ll stick with what I’ve learned and practiced as an AP/IA for the last 30+ years. It’s worked well for me and my customers and I don’t lose sleep as to whether I did my best.
-
For cowling repairs you have AC43-13 to reference. What will you tell the FAA inspector when rig boards are available and you deviated from the maintenance manual? You can talk all around how you can come up with other methods but it won’t get you very far with them.
-
Hate to disagree with you, but that method is unacceptable to the owner of the aircraft I just worked on. Yes, you might get close, but it is not IAW the maintenance manual. Try to explain that to the investigators after the smoking hole has been created. You have no leg to stand on.
-
For the stabilizer, you can’t use the top of the horizontal stab with a digital angle finder as it’s not zero. If you look at a rig board, the aluminum angle that is bolted to it is at an angle and not the same as the top of the stab. I’ve used digital angle finders on flaps, ailerons and elevators to check the throw of each, but the stabilizer is different to determine zero like M20Doc states. Since I have access to the rig board, it made sense along with made it easy setting the stab trim per the maintenance manual. David
-
I just fixed the stabilizer trim rigging on a J model that had a new autopilot and electric trim installed. Not sure how I would have done it and be assured it was right without the rig board. Not saying it couldn’t be done, just not sure how and how long to be assured it’s in book specs. David
