Acclaim down

[mooneygirl]

From another Mooney forum:

"Just heard over the wire that N411JL has crashed outside of Adiran Michigan.  It was at OSH.  Indications appear to be a loss of control and hypoxia suspected by ATC."

 

It looks like the pilot was not injured per a relayed transmission.

It was parked at Basler next to me and left a couple of hours before I did on Friday.

A very strange flight path on FlightAware.  I'm glad that everybody's OK!

[Skywarrior]

Hypoxia at altitude, then a hard landing? There's gotta be a lot more to this story...

Ill bet this fellow(and his family) is just happy to be on the ground in one piece.

[Cabanaboy]

Near the end with the slow speeds and high sink rate do you think he was in a spin? Thank goodness he is okay.

I noticed in the picture in the link that the oil door on the cowling is open.  Do you think that is normal procedure for the fire department after a crash, maybe after the FAA inspection since both the baggage compartment and cabin door are also open (as in open up everyting so we can take a look and make sure there is no fire/fluids) or, do you think this leads to a reason for the emergency landing?  I've never noticed the oil door open in other emergency landing/hard landing type situations before, but then again, I may have just missed it.

Thoughts?

Here's the link to the NTSB report.

I wouldn't think it would have been Hypoxia. He was only over 14000ft for around 30 minutes and not super high. Not saying there wouldn't be effects, but you're allowed to be at 14,000 without oxygen for 30 minutes and I can't imagine that 16,000 would cause you to completely "lose it" in such a short amount of time. Is it possible it could have been runaway trim, flap or gear failure?

That's what I was getting at. He was only at an "oxygen required" altitude for 30 minutes. I should've been more clear on my thoughts on that, but I assumed the the FARs operate on the conservative side of that sort of thing.

I can get pretty stupid pretty quick that high, and have caught myself making errors (and surely made some I didn't catch) even as low as 12,500.  Last time I was at 14,000 for 30 minutes, I was circling in mechanical updraft in a big bowl near Pagosa Springs to get high enough in my 170 to see over Wolf Creek Pass.  There was a Golden Eagle doing the same thing with me, and we sailed gloriously upward at about 200 fpm for quite some time.  My first clue was that I couldn't make sense of the altimeter, then checked fingernails.  They were blue, and that finally jogged me enough to break my camaraderie / hypnosis with the eagle.  Even a minor problem would not have been handled judiciously, and could have been compounded.  And its almost never just one thing that gets you in the deep stuff.

I think if you guys read the posted NTSB link above, you can stop talking about the regs and hypoxia. Here's what it says-

"On July 27, 2012, about 0846 eastern daylight time, a Mooney M20TN, N411JL, experienced a severe nose pitch-up while climbing through flight level (FL) 190 to FL230. The private pilot, the sole occupant, initiated an emergency descent and during the attempted landing to runway 23 at the Lenawee County Airport (ADG), Adrian, Michigan, the airplane landed about 300 feet short of the runway. The nose gear collapsed and the main landing gear separated from the airplane which resulted in substantial damage to the airplane. The pilot was not injured. The airplane was registered to and operated by 4thWave, Inc., under the provisions of the 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident. The flight departed from Oshkosh, Wisconsin, about 0732 on an instrument flight rules (IFR) flight plan."

It sounds a little like the plane that experienced the elevator hinge failure and started the AD. The plane is mostly intact and occupants survived, so it shouldn't be to hard to get to the bottom of it

[carqwik]

This plane was damaged in a landing accident in June 2009 at KSJC (actual damage occurred during a bounced landing at KPAO but plane diverted to KSJC due to possible damage and was further damaged in gear collapse at SJC).  See NTSB report: http://www.ntsb.gov/aviationquery/brief.aspx?ev_id=20090622X51947&key=1.  Whether or not the repairs had anything to do with the Michigan accident is unknown but it is worth noting that the plane was substantially damaged three years ago.

[DaV8or]

I'm thinking runaway trim motor, but it could be the hinge too I suppose. I hope not for his sake. I think the AD was pretty well known. Anyhow, Acclaim owners (and I suppose the owner of any M20) hold on to your wallet!!
