Deathtrap MU-2 BANNED

[Say Again Over]

It's the governor driving the prop to coarse to apply positive torque, or a load, to the driveshaft.

Yes and when the FI fuel flow is bumped up it can't happen, have helped rig and set up many TPE applications.

If the fuel flow is bumped up enough to apply positive torque, you're right, the negative torque sensing system will not activate to increase pitch and load the shaft. However, any time the engine experiences negative torque, the NTS functions to load the shaft.

When you've rigged your TPE's, have you ever made a high angle flight idle descent at high speed to see what happens?

 

[Say Again Over]

Yes, that was my main purpose, very experienced crews liked the maximum performance, i.e. the low FI setting along with the NTS pulsing, not recommended for an inexperienced pilot, the other part of it was to make sure the prop didn't rotate too fast when feathered.

MU-2 show on CNBC

Hey Friday when I came in CNBC was doing a story on the MU-2. The pretty much put the head of the FAA Airworthiness division on the spot about the MU-2 as to why the FAA is having another special review after they did one back in 94 saying the MU-2 is safe with a competant trained pilot flying it. Apparently a former counsel for Mitsubishi is heading an organization to ground the MU-2 until the FAA fully investigates what has called the abnormal amount of accidents in the last 30 years. It was interesting they interviewed a test pilot for Mitsubishi to pilot's families that had accidents in MU-2s to get all views. Here is the link to cnbc http://search.cnbc.com//main.do?target=newsanalysis&page=1&keywords=MU-2, I wasnt able to find the video on the site. It maybe shown again also.
