Thanks for the clarification. That one had me scratching my head.

The heater AD is in compliance - just not by virtue of the pressure decay test being done!!

The pressurization system on the 340 is similar to the Aerostar (with a recent mod kit done) where you can bypass the intercoolers for incoming cabin air.

That provides quite a bit of heat to the cabin.

A number of Aerostar owners that have that mod don't use their heaters much if at all.

What's the status of the exhaust AD's? (Every 12 years, correct?)

I sat in a 340 today, and boy does it fit. I'm in the market for a twin and having a hard time justifying buying something else.

Part (G) of the AD is every 12 years / 2500 hours. That is: remove exhaust, send out to certified exhaust facility for inspection / repair / replacement. If you buy new exhausts, it would probably be $16-$20k. Inspect and replace as required was maybe $7k for me a few years ago. (Price covered both sides.)

The other parts of the AD are every 50 hours (visual inspection), every year (remove tailpipe, inspect / pressurize system and leak check), and every 500 hours (engine beam inspection). If you are on top of all those, there shouldn't be big surprises every 12 years.

The exhaust AD is due 10/2024.

Which part?

There must be something in the logs that keeps dropping the price?

Lots of plane for the money

The correct thing to do is repair inoperative items, especially if you are trying to sell. Now, I'm wondering what other items are inoperative/not repaired.

It makes it seem as if the owner didn't perform necessary maintenance. That would scare me away from buying.

The big part of the ad which I believe is part (g) is due 10/24.

Simply, No.

What is the process then if the plane fails the AD inspection? Does the entire exhaust system need to be replaced or other repairs?

We picked up a 421 a few years ago where the exhaust was just beyond the 12 yr AD limit. Elected to just replace the entire exhaust. Right around $7k in parts. Prices may have gone up since then. I figure the exhaust AD as a fixed expense on the order of $1k/year.
