I know that a few of us have been looking for information on this accident.

From the outset it looks like both the pilot and my mate Adam did the best that they could in a truly ****ty situation.



Eternity.

From the report:
At Kamusi, the aircraft was refuelled from drums. Smoking gun ?

Hell of an assumption ReverseFlight and based upon what? They were a reasonable length into the flight and the couple of incidents I could find in Caravans caused by fuel contamination showed up pretty quickly after takeoff, not after leveling off at 9000ft and then a few minutes into the cruise...

You'd think contaminated fuel would lead to rough running and possibly surging, rather than a sudden "pop".

Until I saw the report I didn't realise the plane became airborne again and then bounced across to the other side of the river. I originally thought that it simple ran off the end of the runway into the river.

After seeing that report a month or so ago, a few of us have been talking about it at length.
The Caravan is a totally different machine with a feathered prop. It will keep gliding and not wash off its speed very easily. To get into a strip like that you would almost need to get behind the drag curve really early, come in with a sharp angle, and then flare.
A flat approach just will not work.

Had he even managed to dump the flaps and get it on the ground... wheel braking alone probably would not have stopped that aircraft.
On a good day with all ops normal on a grass runway with no slope at MAUW, it takes a good 400m to stop one. Take away the option of reverse, or even beta, its a pretty safe bet that it will be at least 600m on a dry runway.

Most caravan guys have barely seen how this machine glides with the prop in feather. A flight safety course in the states with the simulator is worth its weight in gold.

As for the cause of the engine failure, wasn't there a rumour floating around somewhere that there was a rather large hole in the side of the engine?

The Caravan flight manual does not explain how to do a correct forced landing with the prop feathered. most operators and Pilots I have flown with over the years do not either. If you do it like the book says you will finish up off the end of the place where you want to land. This is normally what happens in most cases when one lands with the prop feathered. Always a good lesson to pilots when training.
I spend allot of time teaching guys how to land on the spot when in feather and with practice they can get it right every time. Hopefully if they ever do have to do it for real they might have a chance of pulling it off .
By the way I only use zero thrust below 2000 feet, too many prangs if its left in feather!!
We use an approach that comes in on an angle to the touch down point, slide slip if needed and dumping of flap.
Easy to get down if you know how but if you are low and falling short not much you can do about that.
I know you Aussies love the "Book" and it covers your arse but not much good if it kills you.

How much control would the pilot have had over prop pitch once the engine died?

I hate it when I my PT6 has "rough running" A320 sim....
