PT20J

There is no structure in the wing behind the leading edge to the spar outboard of the fuel tanks except the for the ribs. For comparison, the previous owner of my airplane bashed the right wing in 2017. It was fixed by Maxwell. They replaced two ribs, a skin, a wingtip lens and a few other minor parts for $1327 in parts and $4085 (43 hrs) labor. They primed the repair and scuffed the top of both wings and painted them for $2168. Total cost with tax and shipping was $7803.40. Keep in mind this was six years ago. Still, it's a lot less than $15K and you don't have to paint the top of the wings which adds cost if you don't care about a slight paint mismatch. You might call Don and send pictures for a second opinion. He was crazy busy when I was there in April with planes backed up all over the ramp and in hangars, so he might not be your quickest option. But, I'd give it a shot. I might also call the Mooney service department and see what they say. I believe they are actively seeking work to generate revenue and the parts department is close by .

Well, obviously if it shimmies, or directional control is compromised, it should be fixed. But that is something that will be obvious and doesn't come on suddenly. The OP wasn't complaining about steering issues but asking what to do about a notation that a maintainer made that the steering has "excessive" play. The truth is that they all have some play in them even when new because of the design and there is no spec on it and so how much is too much is determined by the owner and the maintainer.

The “eight second ride” is about a nose wheel caster adjustment on pre-1977 airplanes that may not have been set up correctly at the factory. It is covered by SBM20-202.

The G3X likes to be the center of its universe. The only advantage to having FS 510 is being able to upload databases wirelessly (which some report doesn’t always work well). Bluetooth doesn’t have enough bandwidth for a speedy database update. FS 510 has a WiFi interface for that but the G3X does not. Whenever Garmin gets around to refreshing the G3X hardware, it’s a good bet they will include WiFi. But, that’s just a guess.

The nose wheel steering is not one of the strong points of the Mooney design. There is no spec on the play that I’m aware of. Blocking the pedals is part if the rigging procedure and not normally done during inspections. If you are happy with it and your IA considers it airworthy then leave it alone. The worse that happens is that you have to do a lot of footwork to taxi straight. if you want to fix it, it’s fairly simple to put it on jacks and replace the parts with the most slop. In my case, I greatly improved it by taking it to an experienced MSC. They shimmed the steering horn and replaced a couple of rod ends. Didn’t cost much and it taxis much better now. Skip

Garmin doesn't make it simple to figure this stuff out. Probably the best place to understand Connext (Garmin's marketing term for wireless data sharing) to tablets is the Garmin Pilot User's Guide because this app connects to all the products. Still, some of the descriptions there seem to have been plagiarized from other manuals and contain no new information. Keep in mind that Garmin products overlap in their capabilities and so it is possible to connect to more devices than you actually need to. G3X Bluetooth: Flight plan transfer to and from G3X; GPS data from G3X; AHRS data from G3X. These all work with ForeFlight. I believe that Garmin Pilot will also link EIS data from the G3X and download csv files of flight log data, but I don't use Garmin Pilot and haven't tried this. GTX 345(R) Bluetooth: ADS-B In weather and traffic to the iPad. Note that in a G3X panel, the GTX 345 internal AHRS is disabled. The FS 210 is, in my opinion, redundant. The AHRS in it is not going to be the same quality as the G3X and G5. For me, as a third, I wanted a completely separate instrument and installed an AV-20-S. So, with two connections, you get everything. I also Bluetooth pair my phone with my audio panel (PMA 450B in my case) to allow using the phone with my headset and playing music stored on my phone.

External IFR GPS mode indicator. Probably an older GPS that required this (it used to be common on IFR GPS STCs) was removed and this was left behind.

Master cylinders? Under left exhaust cavity behind cowl flap.

Can you install standard standard AGC type fuse holders somewhere around the dimmer controls and wire in place of the expensive fuses?

Threads are galled. I would replace the hose and firewall fitting.

I recently rebuilt my Cleveland master cylinders. I ordered the O-rings from Spruce using Parker documentation, but when I was looking at the M20J IPC, I noted that it included an exploded view of the cylinders including Paramount and appears to show the internal O-ring part numbers. You might check your IPC and see if it has similar info and cross check the part numbers with the LASAR kit. EDIT: Here’s the M20J IPC pages if it helps

Maybe the rings lost their seal due to the cylinder being worn out and the blowby is what overheated them causing them to lose their temper.

Mooney only sells parts through the MSCs. There are 39 MSCs in the US. Each maintains its own parts inventory primarily to support its maintenance business. They also set their own markups, so parts prices vary between MSCs. I don't know how many have computerized their inventory. Of them, only LASAR seems to have actively gone after parts sales as part of its business model. The new owners are not maintaining the same level of stock (it may not be available from Mooney) and have recently increased markups on parts they order from Mooney. I talked to two well respected MSCs (Maxwell and Advanced) and neither owner was crazy about the parts business. Of course they will sell you something if they have it, or order it for you from Mooney. But, there isn't enough money in it to make up for the time it takes and dealing with customers that don't know which part to order or order the wrong part and complain about Mooney's restocking fee, or gripe about the price and shipping cost, etc.

It’s probably not at the right wing station for the factory light which also wouldn’t cover the upper portion of the damaged skin. Probably quite a bit more expensive than fixing the damage.

That’s the fitting for the fuel pressure line. It replaces the pipe plug in this diagram. It’s the wrong fitting. The filter has multiple layers and actually filters 74 microns according to the RSA manual.

Depending on if there is any hidden damage, it is probably easy to fix it up enough to get a ferry permit. I helped do that on a twin Beech that hit a sign when it ran off the runway after a brake failed. We got some sheet aluminum and pop riveted it over the leading edge to reform the airfoil shape.

Really nice work!

The price sounds reasonable. You can call any MSC and get the price on the skin, but they are pretty inexpensive as airplane parts go and certainly not worth buying a wing. Mostly it's just a lot of labor removing the old skin, installing the new skin and prep and paint. If any ribs were damaged that will increase the amount of work and the cost.

LASAR's parts markup seems to have increased lately. The PMA version comes from GLAP (which I believe is also the OEM supplier to Mooney). GLAP shows a M20J lens for $99.40. I know for the wing lenses GLAP will trim to size if you send them the old one, so they might do that for the cowl lens. I'd call them and ask. http://www.glapinc.com/Mooney/m20j.htm Skip

I’m not clear about the terminology “high-angle fitting” and “screen holder”. The screen fits into a barrel bored in the servo body that is threaded at both ends. One end accepts the inlet fitting and the other end accepts a plug.

Mooney used AN380-53 cotter pins for all four seat stops at least through the M20J. I substituted a 6-32 screw, two threaded spacers (one on each side of the rail) and a stop nut at each location. This provides a more positive stop, and is more easily removed and replaced. Skip

As @N201MKTurbo said, there is no such thing as a patch. There is such a thing as a repair, and as @Shadrach said, if the sealant is not deteriorating and has good adhesion except for the location of the leak, there is no reason that a properly done repair will not work. My 1994 J was repaired twice by Mooney under warranty and once by a previous owner many years ago, and it doesn't leak. In 1987, I purchased a 1978 J and one tank was repaired by the previous owner and it never leaked in the seven years I owned it. Repairs are expected -- that's why there is a procedure in the service manual. But, it has to be done right. Find a shop like Maxwell that has done a bunch of them.

New, rebuilt and overhauled non-turbo engines shipped from Lycoming have had roller lifters for nearly 20 years, so there is a lot of positive history with rollers. The DLC lifters have less history, but are a much less expensive alternative for a field overhaul.

I would. It’s hard to tell from your description what’s loose, but if the B-nut is snugged down, the hose should not be loose.

Is the B-nut on the end of the hose at the firewall end tight?
