It seems from todays news, that "catastrophic engine failure" might be the cause of this accident. Plumes of smoke were seen pouring from the engine as the plane was climbing off the runway - witnesses said they heard loud "pop pop popping" sounds as the aircraft tried to climb, but did not achieve. It clipped the top of some trees and ploughed into a farmers irrigation dam right of centre, about 1/2 a klm from the end of the runway.
Apparently the engine was modified some years ago achieve more power, and since that thime there have been numerous problems - all repaired mind you. There was mention of crankshaft trouble as well. Doesn't sound as though this particular aircraft was totally fault free during its life.
Also, there has been media mention of another Cessna 206 that crashed here in Australia a number of years back in almost the same fashion.
Sorry its more bad news - but this sort of thing is not a regular occurrance in Aussie.
