Parts support, combined with the aging out of the ownership population, will be the death of this brand.

To close the loop on this, the one-piece seal the A&P installed seemed to solve the leak. I did notice that the oil return tube rubber couplings on the bottom of the engine were very loose and could be spun by hand. The hose clams holding those in were tightened and a noticeable decrease in belly/gear door blow-by was evident after a few hours.

Bumping this back from the dead. Where are people sending their D4LN-3000 magnetos for inspection/repair nowadays? Thanks in advance.

Yeah, I found that one here and have familiarized myself with it. It's a very well-written SI, considering that some I have read read like they're intended for engineers and not maintainers.

I'm going to live it, lube it, and love it before installation. And order a spare or two if it breaks it in two.

Thanks, guys. Parts on order.

I'm bringing this back from the dead. The seal on my M20J is starting to leak. About 5 years and ~500 hours after overhaul. Is the general consensus that the one-piece (LW-13792) or the Superior equivalent (SL13792) seal still the way to go?

Thanks again, Marc. I greatly appreciate and value your help! Have a safe evening!

Good morning guys, Is IAI still in business? I called this morning, both of their telephone numbers, and some Spanish-speaking lady answered and abruptly hung up. They haven't replied to my email from a few days ago either. Thanks in advance!

1981 and these were installed prior to my ownership sometime around the mid 1990s. I'd have to grab the manuals to be certain of the date.

At least 10 or 15 seconds, or at least the time it would take me to process the thought, 'I wonder if this is going to retract by itself or if I'm going to need to rock the wings a little bit' and 'I hope the rental car is at the FBO when I get there because it's a bitch to get these people on the phone.' If I didn't do something, who knows if it would have retracted on it's own. Excellent. I will look at that this weekend. Thank you!

Correct. SBS light is too dim to be meaningful. Even in the nighttime, it's of marginal utility. Yes, ADI. It seems to work as intended and no obvious issues. The left side retracting slowly happened during the runup and in-flight. I flew it for 6-00 earlier and that's the only squawk I have for it.

Good evening, I hope everyone had a safe and joyous Christmas and is thoroughly enjoying the holiday season. I think I have a vacuum leak and am wondering where I start troubleshooting or having the shop investigate. First, the SBS on the left side retracts significantly slower than the right side. Second, when pressing the extend/retract button, the pitch of the sidetone changes significantly through the headsets. I only have the idiot light on the panel so I can't say what the vacuum is actually pulling. The pump is about 5 years old and ~350 hours. Thanks in advance!

I did have some avionics work done on the airplane earlier this year and I want to rule that out, but I had so many issues with it, I'm having a hard time preventing that. They also allegedly gave me a IFR/VFR check out of it without any issues. This is mounted on a nearby bracket. I traced out all the lines and fittings that I could see and all the B-nuts were at least finger tight and nothing obviously loose. Is this diaphragm replaceable with a new celophane/rubber? It's surprisingly easy to access and it seems like the switches are still hard to come by.

Inches of water? I'm going to have to google that up. That's Greek to me.
