Deathtrap MU-2 BANNED

[avbug]

And let's see, here, the Piaggio was built in the 60s?

How can you even compare these two? They are designs from different eras, hence the difference in technology.

I'm not criticizing either, but a Piaggio also blows away a Citation I.

I was responding to a post above which stipulated that the MU-2 wing is too small for ailerons. It's not. I cited the Piaggio because it's wing is smaller. The poster stated "the sacrifices we make for speed," which doesn't hold water in any part of the arguement because considering a small wing as part of the factor ignores the fact that comparable aircraft (size, weight, power) have very different histories. The small wing gets blamed as part of the "dangerous airplane" condemnation...along with the spoilers. It gets blamed in ignorance, because that isn't the cause for the MU-2's history. Pilots are the cause.

Avbug,

agreed.

I just received this from Aviation International News...

"On Thursday, the FAA plans to release a proposed special FAR (SFAR) mandating recurrent training for all Mitsubishi MU-2 pilots. The notice of proposed rulemaking (NPRM) will have a short 30-day comment window. After a two-year period (2004 to 2005) in which 14 people died in 12 MU-2 accidents, an FAA evaluation determined that the MU-2B is a “complex airplane requiring operational techniques not typically used in other light turboprop airplanes,” according to the NPRM. While Mitsubishi Heavy Industries America has long pleaded with the FAA to require a type rating for the MU-2, the agency said this would not help because type ratings do not include mandatory recurrent training. Pilots will have to be in compliance with the SFAR 180 days after the rule becomes final. The FAA did not say whether it would apply the same training requirement for airplanes that have a higher accident rate than the MU-2, including the Piper Meridian, de Havilland -6/7/8 series and Merlin/Metro."

Finally, something constructive.

This thing has been in the making for over a year now. Finally they get it together.
This could have been done six months ago.

Pilots are the cause.

So we should remove the pilot and make the MU-2 a UAV.

(couldn't resist)

 

[avbug]

The way some pilots let the airplane fly them, it already is unmanned...

 

[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.

 

[avbug]

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.
