Skymaster Down

[edasmus]

Yes Herb, I did notice that on the rear prop as well. I agree that he did a great job safely landing the airplane. Is anyone out there experienced in making a judgement as to whether the front engine was making power at touch down or simply windmilling based on the damage to the front prop? I always find it amazing as to the strength of the hub and blade shanks when I see curled prop blades. One would think that the blades would just get ripped out of the hub on initial impact or the blades would break. It is quite a testament to the design and engineering folks who built these machines.

It appears it was making power by the twisting of the blades.

A couple of weeks ago I was getting my BFR and the CFII pulled the rear engine, and nothing happened, except that we went a little slower. Of course the book says Full Power on the operating engine, which I did, but that seemed like a waste of fuel and just made a bunch of noise. We are both pretty big guys, and I had just topped off the plane.
Which brings me to the point of this thread : Why if this guy was by himself, with one engine operating, did he put his plane down in a field?

There is something about this accident that doesn't add up.

I agree, something doesn't add up. Sole occupant, so it's lightly loaded and should fly well on one engine. Front prop was turning, but might it have been windmilling because the pilot failed (or didn't have time) to feather it, given one eyewitness' statement "I heard no power"? I always think of running out of fuel, but Valdosta, GA, is real close to the accident site -- hard to believe the pilot didn't check fuel quantity before departure.

It's been many years since I went through the Crash Survival Investigators School and did aircraft crash investigations but as I remember, when the props are bent back like the front prop is, that says it was windmilling. When the blades are bent forward, that says that the prop was producing power. Could be wrong but if you play the odds, this fellow ran out of fuel. We'll see what NTSB come up with.

[WebMaster]

Either that, or he had a blockage that stopped both engines??

Nope, don't like that idea, either.

NTSB report should be interesting. I note that while the wing was ripped off, the wing attach point was still visible on the fuselage. Maybe Cessna will note that, as well.

I wonder how cold it was ? maybe it was like the one that went down over the frozen atlantic with "both engines" freezing at exactally the same time.
