Ensuring that landing gear systems are serviceable is absolutely essential but it's often a neglected part of many small airplanes. Incorrect wheels, tires, and brakes are items I find all too often and have the potential to really spoil your day. Retractable gear that is allowed to wear beyond serviceable limits and deteriorate due to corrosion and rust is a sure fire way of having a gear collapse! Make sure your landing gear gets the attention it deserves and is serviced by a knowledgeable and diligent mechanic.
This is a stunning video. Love it. As a new Mooney owner I feel actually educated after watching this. Please do lots more
Thank you for your comment. I am planning on doing more Mooney maintenance videos. Congratulations on getting your Mooney and I hope your enjoying it.
Very nice video! I wish my Mooney looked like yours under there! Well done!
Best Mooney video I've seen! It would have been good to see or hear how you apply enough force to compress the new rubber donuts during installation. Thanks for the excellent video and hope to see more.
Glad you found it helpful. I will see if I can sort out getting you a video of how I do the compression of the shock discs.
Thank you for this wonderful video, and I hope that you will share with us all kinds of maintenance that you do because it is useful and cultural for everyone as pilots and owners of this type of aircraft.
Thanks very much. I will certainly get some more maintenance videos done.
I have a Mooney 201, and think a video of you changing the pucks would be great for the Mooney community. Enjoyed this one as well.
I will take a look and see what I have in terms of footage for changing the pucks. This job was so involved I ended up with the gear completely removed from the aircraft so it is not a standard puck change.
We just had a nose steering torque tube fail. On a M20F . Repair made by Lasar Inc. very good video. Thanks.
I am very sorry to hear about the torque tube failure. I just finished an inspection on a Mooney that required alot of gear work. The number of worn componets gets really alarming. Rod ends, hinges and bolts with enough play to start causing issues. As the airplanes age and the hours build on them its going to be more and more imortant that correct inspections and replacment of worn componets occurs to prevent failures. I hope you have your airplane up and flying soon.
Nice 👍. Thanks for the video, very informative. I just bought a 1968 Mooney M20C, going to be a nice restoration project :)
Congratulations on your purchase. I look forward to hearing about your progress.
Great video, great to see the manual landing gear mechanism of the Mooney, keep em comin', much appreciated!
Thanks for your comment. I should have some more Mooney maintenance content coming soon.
@@fastbackflying853 looking forward to it, thanks for taking the time to make these videos..contemplating a Mooney M20C or K
@@noelmasc.4348 I hope your purchase goes well. I have a review video on the Mooney as well as a video on items to consider when purchasing an aircraft. Let me know if you have any questions.
Love these maintenance vids!
Glad your enjoying them.
I have maintained my 59 A model for near 15 yrs. My original manual (and the design has not fundamentally changed) discusses check ing the over center link actuating rod compresive Force with the palm of your hand. The later SB which you reference says to check the pre load at the moment the link begins to move. This is a subjective observation and many shops, a&p's overload the system so to prevent the over center link from actually "falling" into a locked position. Also the system is comprised of 4 compressive actuating rods. Adjust one and it effects the other 3. The fundamental talk misconception is that the actuating rods hold the gear down - not understanding the simple genius of the "over center link". Same device used in the door latch and the baggage door hold open device. Long live the wood wing! Al & Art's last original.
Those A models had the B & C models beat by 5 to 7 mph.
Thanks for the information.
You are very welcome
Great video! I have a J model.
A few extra gear doors on your model! Glad you liked it.
Can you do a video of the steering horn and what amount of slack in it is acceptable and for the shims that go on the nose gear for proper alignment to prevent castering.
I will keep this in mind. I do have some repairs being scheduled for the nose of a couple Mooneys but it might not be for a year.
Great video. Towards the end, in the main gear wheel wells, we see the retraction rods and the 'walking beam'. There is a fairing removed that would stop debris, dirty water spinning of the tyres etc from filling the wheel well. I take it that's aftermarket. Who sells them? Thanks.
Hi Denis, the fairing you are referring to is an OEM part and can be found in the IPC for the airplane. They were installed on this aircraft before it was released back to service.
what do you usually inspect in the hydraulic pipelines inside the wheel bay?
I'm trying to figure out this task for a m20c and I'm having a heck of a time. The manual said to disconnect the tubes at the bellcranks(for the mlg-the ones you pointed to) and I'm not so sure I needed to do that now
Sorry for the delay in responding to you. Remember that the maintenance manual rigging instructions have you set the gear up for a zero pre load condition prior to making an adjustment to the retraction tubes. The older B model manual provides separate instructions for inspecting the pre-load that exists in the system. Later models like the G & F do not give you an inspection procedure that does not include going through the entire rigging procedure. Do you have the maintenance manual for your C model?
@@fastbackflying853 we do not, we are currently using a m20j manual. It tested in the right range when using the torque tool, inspected and lubricated everything. We did not need to make any adjustments
I am glad to hear that they are all in the correct range. I would strongly suggest getting an appropriate manual for your model of aircraft. Manual gear models have different checks on the nose gear compared to the electric gear models. I hope your enjoying your Mooney?
If you read the manual in detail you will find you are not suppose to move the gear from underneath the aircraft. It can and will result in bending or damage to the linkage. 15 years of Mooney love. Owner operator of a J and maintain and fly a G with manual gear.
Yes that is correct but only when linkage is undone.
Where is a good mooney shop. I have a 67 E model and it's in good shape. The annuals have been done by three different shops but none were familiar with the Mooney. I need to find someone with real working knowledge.
You can have up to 0.60 inches of play at the top of the shock disks on the mains.
That sounds about right. I would have to double check the maintenance manual. That play is with the aircraft on the ground at gross weight. This aircraft had a massive amount of play in this location when the aircraft was jacked and no weight was sitting on the gear!
do you have a nose gear removal video
No I dont have one on Camera. I will likely be pulling a nose gear in the next year so I will make an effort to get some good video of that process.
Are you an A&P or something? I'm buying a Mooney and I really would like to find someone that can really go through whatever bird I get and get it to a top notch place
I am an aircraft mechanic in Canada. We are called AME (aircraft maintenance enginer) here. It's like an A&P with IA. What model are you looking at?
@@fastbackflying853 well I actually bought a M20J
@@joematties7557 congratulations thats very exciting. Have you managed to get some flying done?
@@fastbackflying853 not yet. Arrives Monday
The Aerospace Industry calls it a Bungee.
Yes they do but it really is a spring. The nose gears on Musketeers have bearing but what they actually have is bushings. I guess they like to play with words
I think you're confusing tension and compression.
Are you a Mooney service shop?
I am not and official Mooney Service shop but I currently look after three Mooney aircraft of different models and have done a fair bit of extensive repairs and rebuilding on them.
@@fastbackflying853 Do you take in other planes or full with the ones you have now. Can you refer a good Mooney shop?
@@claythomas9509 Yes I am able to take on some extra customers at this time. Please send me an e-mail if you would like to chat some more details and I can either get you fit in or recommend a few other shops depending on your location.
@@fastbackflying853 I can't find your email address. Where do I look for it?
@@claythomas9509 its james@fastbackaviation.ca
Nose wheel broke on one M20. Chromoly. Kaput. Beech Musketeer has a wonderful gear.
That Musketeer nose gear steering is a nightmare to repair when the bellcrank gets cracked or damage there's no access. Early ones has a castering nose gear.
