Airplane too old and death toll too few and too far away to garner media attention- Sad truth.

Let us know when the final report is issued- there are probably some swiss cheese layer aspects to this- or poorly-trained pilots + poorly-maintained aeroplanie in a poorly-regulated environment.

"engine failure, propeller could not be feathered" (AVHerald).

From the avherald summary of the preliminary report today, it kinda sounds like they shut down the wrong engine :cry:

It sounded to me that they could not feather the failed engine and hence they didn't have performance to maintain level flight and were forced to descend.

It also sounds like instead of performing an emergency landing under control they finally lost control of the plane. The DC-3 has a quite low stall speed and I would expect a crash landing under control to be more survivable and to leave a longer track on the ground. It almost looks like the plane was dropped from a crane.

Doesn't the graphic on AvHerald (overimposed on a picture of the crash) show a flat spin? There's also mention of high rate of descent, but low speed (honest parlour talking asshat question).

The picture says impact path so I supposed is what the plane did after contacting the ground, not before. Like it hit with the left wing and sort of cartwheeled.

That would be sufficient, yes, but note (a) the reports that it was the left engine failed, and (b) that the a/c was found with the right engine shut down. Could be that reports (a) were wrong, though. Simon commented on it later on Sunday. (in the comments, not the main article)

If that's what happened it wouldn't be the first time...

I haven't seen the reports regarding the left engine being the one that failed. But anyway, even if they shut down the wrong engine, even if both engines failed, whatever... My point was that they did not crash under control. In any of these cases a crash landing under control should have been possible and a much better outcome than what happened.
