47U

Heather is still taking orders… I signed up for one. Even if my current one is still airworthy in 10 or 12 years when I decide to hang it up and put 47U on the market, having a spare intake duct should be a huge selling point.

Oscar… LASAR website says the STC is limited to open baffles (no doghouse), 1967 and later E / F models. https://lasar.com/stc-kits/laskit126

Check with LASAR. Gather up the part numbers and give Heather a call. You might check their website to see if they are in stock. They won’t be cheap, however. About 15 years ago I replaced a handful of gear bushings and they were .3 amu. But, it fixed the main gear from fully retracting and hanging an inch below the wheel well opening. If you call around other MSCs might have better prices. And, you can type the part number into the search window on controller.com and one of the parts warehouses might have bushings in surplus stock.

I would think a loooong time, if kept in an air tight bag with desiccant in a dark closet in your house, not the hangar. That would be my plan. Then, after I’ve passed on, my heirs will find it, wonder what it is, not realize its value, and toss it in the bin. And declare me a hoarder. I replaced my intake duct in 2010. LASAR had it in stock for just over .3 amu. I’m contemplating ordering one for the future, but mine is in such good shape I’m debating on maybe waiting for the next round. I had to do one small repair where I had allowed the carb air duct to touch the intake duct. It had a pea sized chafe mark on top of one of the reinforcing wires. I repaired it with some fiberglass cloth and high-temp black RTV. That was several years ago and the repair is stable. If I had an E or F, I think I’d order one, regardless. They appear to be subject to more wear than the B/C/D/G models.

Part of the problem here is that Mooney used Stratoflex 193 hose, which isn’t rated for fluid. It rated for low pressure air/vacuum. My friends G model had a puddle of 5606 on the floor of his hangar one day last summer when this hose failed at an adel clamp. I was surprised it was a 193 hose because when I installed new hoses in my ‘63C, this hose was Stratoflex 111, rated for hydraulic fluid. Someone before me had upgraded the hose from 193 to 111. I initially thought someone had installed the wrong hose in my friends G model, until I looked up the part number. Surprise, surprise. I had some -6 193 hose in work order residue so that’s was we replaced his failed hose with. As for me, I’m sticking with my 111 hose.

That’s not right for you to be picking on poor Mooney like that. April fools day, or not. I’ll bet AI wrote it.

I had one of those. There’s a wire ‘bale’ welded inside the end of the exhaust pipe that goes into the muffler. Photo credit to Wag-Aero.

I’m NOT an expert. But I think it might be better to sell it for the core value. I don’t know what the shelf life is on a pump sitting in box. Five years? Ten years? In a hot hangar in Fort Worth (or Sacramento)? I think I’d rather install a pump either new manufacture, or with a short time elapsed on the shelf since overhaul. My opinion might be biased, though. The last airframe I worked on in the Air Force, it wasn’t uncommon to go into phase inspection with over a hundred time changes scheduled. And yes, sometimes we had mx induced failures.

I have this part, if it helps. PN 600028-505.

Your IA might have incorrect information. I called Knisley a few weeks ago to inquire about a modification to my muffler shroud. A person who works for AWI in Minneapolis answered the phone. He was attentive to my questions. If you call the old Knisley phone number, your call should be forwarded to AWI. I can PM you an email address to the AWI rep I talked to, if you wish. Knisley - (800) 522-6990 AWI - (800) 597-4315 Edit: Sooooooo… AWI is a subsidiary of Hartzell. Learn something new everyday (I hope). Thanks Rich!

If you’re looking for approved methods and practices, the military tech orders can be a good source. The 01-1A-8 is particularly useful for guidance on structures and hardware. https://vdocuments.site/navair-01-1a-8-structural-hardware.html?page=1

I’m guessing the engine driven fuel pump. How old is it? I read on the RV forum that Lycoming recommends a time-change at the 10 year mark. I’m not sure if any of us CBs are actually doing that. I replaced my (‘63C) engine driven fuel pump three years ago when I was experiencing some fuel pressure/flow fluctuations. That turned out to be a cracked flare on the hardline between the gascolator and the elbow in the pilot’s footwell. The pump is sitting on the shelf in the hangar… I could send it to you for troubleshooting purposes. IF you wanted to go through that much pain to install it, then replace it with a new/overhauled pump if the problem is with your existing pump. It’s really not a fun job. Might be prudent to check how old your hoses are, too, just because you’re in there. If you’re paying shop-rate to do this work, you might be money ahead to just install a new/overhauled pump to begin with. Hopefully someone with more experience than me will chime in with a better idea.

There was as Piper Pacer with a glider hook two hangar rows over from me… looks pretty simple.

A valid consideration… I certainly discussed this mod with my IA before I went forward. When working with my IA, it’s better to ask for permission rather than forgiveness.

I didn’t have room for the rocker switch ignition panel, so I installed two DPDT mil-spec toggle switches. I put them on top of the radio stack, where nothing else fits. I moved the ship’s Master switch and the ELT panel there, too. I adopted a mag switch schematic I found on a RV’r website. Both mag switches in the ‘up’ position grounds the right mag and energizes the starter solenoid. The left mag (SureFly) is hot. When the engine starts release the switches, they’re spring loaded back to ‘center’ and both mags are hot. Inflight mag checks are a piece of cake. No more after-fire from not moving the key quickly enough with SureFly latency on the left mag. Shut down is normal… pull the mixture, when the engine stops both switches in the ‘down’ position grounds both mags. After shutdown, I do have to double/triple check that the mags are cold, both switches down. But, there’s virtually no chance of inadvertent starter actuation because both toggle switches have to be ‘up’ to complete the starter circuit.

No disagreement. Part of the issue with rebuilding the steering horn in the field (in my opinion) is the lack of the blue-line drawing listing the individual joints, bearings, shims, bushings, etc. that makes the rebuild both functional and compliant. As the resources to keep our airplanes airworthy dwindle, those resources that remain available will likely command a premium price. I can’t refute your pessimism, it’s just the way it is. If an owner/pilot is experiencing the 7-second ride, 1.25 amu in parts to get it fixed might be economical compared to the costs associated with repairs due to a runway excursion, or the increase in insurance premiums. I wish I had a better solution, but I guess I’ll support the resources that are currently available and hope the resources are still there when I need their support in the future.

I think you mean 1/8” baffle seal? And a high-temp RTV to secure it, (unless there’s a rivet or screw… I have no knowledge).

I talked to LASAR about 10 days ago (I’m told Dan is retired, but Heather was knowledgable to my questions). LASAR doesn’t have any rebuilt steering horns in stock, but will evaluate yours (for .15 amu) and, if it qualifies, overhaul it (another 1.1 amu). Mooney will make you a new one for north of 2 amu… other MSCs may have different pricing on new manufacture. The LASAR website shows this as a 1968 and earlier steering horn (what I have on my ‘63C). LASAR shows this as the ‘69 and later… my understanding is that the older and newer versions are not interchangeable. So, I sent LASAR my steering horn and am waiting to hear what they say. I wasn’t on the 7-second ride yet, but there it was pretty sloppy when up on jacks. I didn’t see any reference in the logbooks where the steering horn had ever been worked on.

The same is on my ‘63C. If I ever replace them, I’ll go with a cushion clamp.

The Mooney Chronology website shows sn 2208 as smack in the middle of the 1962 production year, which produced sn 1940-2276. The FAA says that 2208 was exported to Canada? Take as good a care as you can with the carb intake boot. They are becoming almost impossible to find. Many manifold pressure lines from the firewall forward have been converted to a -2 hose. Mine hose connects to a reducer on the hardline at #3 cylinder, the MP pickup is off #1 cylinder. As far as other suggestions… if the interior is in good condition after sitting, it sounds like it was hangared. That’s a positive. Still, SBM20-208B should probably be done if it was kept on the ramp for any length of time to check for corrosion of the fuselage tubes (if the windows leaked) and SBM20-217, inspection of the stub spar for cracks where the flap actuator connects to the flap torque tube. Small cracks can be invisible. It helps to pump the flaps all the way down which puts stress on the stub spar and opens up the crack. There’s quite a lot written on rigging here on this board… some say you don’t need the travel boards. But, they sure make it a lot easier, I’m sure.

Welcome, Brian… The 8 pages of M20-139A are fairly self-explanatory, but I can see where it would help if the person doing this has previously replaced shock discs. https://www.mooney.com/wp-content/uploads/2020/12/SBM20-139A.pdf There are parts specified to be replaced, both on the nose and main gear. If your local MSC can’t source them you’re probably relying on sourcing salvage parts. Which will need close inspection to determine airworthiness. Keep us updated on your progress.

The ‘end repair’ method of compliance (and retire the AD) is applicable only to F models sn 690001 and on. The Mooney replacement shaft’s part numbers spec’d in the SB will use the original yokes, but I do think they are 2” longer. A couple years ago, an acquaintance with a ‘65 (66?) E model ordered them and Mooney manufactured them. They weren’t cheap, though. I’m thinking it was two or three amu’s.

That’s positive. Surely it has a metal empennage… ?

I have an automotive brake bleeding pot I got from the auto parts store. Some have used a cheap garden sprayer. It doesn’t need to be very big. To bleed the flaps, the connection is made at the T on the flap actuator. It’s a male -4 AN flared fitting. Appropriate fittings to connect the hose off the pot to the T can be sourced about anywhere, including Aircraft Spruce and your local auto parts or hardware store. I found that it works better to loosen the flap retract rate screw (with the big jam-nut) on the flap pump in order to flow more hydraulic which helps push the air out of the system. Of course then, you’ll be adjusting and readjusting the rate screw forever, until you get it ‘just right.’
