Urgent A&P Help Near KDVT

[JimC]

I had that happen to a twin turbo plane (both wastegates stuck open at the same time after an extended sit.)

I didn't get off the ground - it showed up on the takeoff roll.

Herb is about 100% righ,
t you need to get it coated with mouse milk lubricant so the gages work properly. I've seen this problem, and the plains been setting in a dry climat like Phoenix
Good luck but don't let them try to sell you a couple of new turbos, check the wastegates first.

Thanks guys,

Do y’all think if is rust forming while it’s sitting? I’ll try the mouse milk if I can find some. Plus I’ll head over to Falcon.

I didn’t come down with tools so about the only thing I can do is beat ‘em with a big rock 🤭😂

Well, I liberally applied the mouse milk I found to the butterfly shaft ends and got my Initial nstructor ready for another test flight.

Then Murphy decided to kill my Gill battery!

Now the mouse milk has had time to soak 🤬

This is what the Instructor wrote down on the last flight. I thought he wrote down more data???

[ Manifold Pressures with cowl flaps open;

RPM top of green:
11k 30 33,
13k 30 30,
14k 30 30,

RPM to 2450:
14k 25 25 ]

If we can fly again, is there anything we should record better or use different aircraft configurations (like crowl flaps open/closed; cabin pressure on/off; etc?

Hi everyone,
Still looking for an A&P. Called virtually every A&P in the Phoenix valley based upon mechanics lists from the FSDO, A&P friends of friends, spot sightings of mechanics working on planes and everything else I could think of.

Now I have to broaden my search to other states. I’m willing to get a ferry permit from the FAA if required but I don’t really want to fly across the middle of the country.

Does anybody have any recommendations for competent, not-insanely-busy-with-month-long-waiting-lists, maybe willing to travel, Super 337 pressurized A&Ps?

Thanks in advance!

Forgive me if I'm misinterpreting. But it seems like you just need a mechanic who is familiar with the engine (and turbo), not particularly a Skymaster mechanic. If I'm correct, finding someone to work on your engines shouldn't be too hard.

Those smarter than me might be able to speculate whether a problem with the pressurization system might cause the MP gauges to read wrong (though I don't think so).

Throttle cable slippage? Can you make full rated power on the ground?

Sorry I'm not able to be more helpful.

If you don't mind a flight to San Diego, Advanced Aircraft just did a very thorough annual (that acted as a pre-buy) of N70S, my new (to me) 1974 Pressurized Skymaster. They are at Montgomery Field (KMYF).

The previous owner paid for the work, but I was very happy with the quality of what has been done.
