Witness report lacklustre initial climb followed by a turn (stall spin) at low level before impact. Density altitude similar to the single engine service ceiling ie there would be no climb on one engine. Sadly another case where a single would have been safer. My opinion.

Pilot William Scott-Bloxam killed in Mareeba crash remembered as 'colourful character'

Police said they would investigate reports from witnesses who heard a strange sound from the engine, described by one person as "backfiring".

 

Mr Scott-Bloxam was still alive after the crash but he could not be saved by paramedics and died at the scene.

 

He came to national attention in 2008 as the pilot of a flight to the Papuan town of Merauke in which he and four others were detained by Indonesian authorities for entering without a visa.

 

They became known as the "Merauke Five" and were held for several months. They were eventually sentenced to between two and three years' jail each.  Following intervention from the Australian Government, their convictions were dismissed by Indonesia's Supreme Court and they returned home in June 2009.

single, twin, 3 or 4 engined aeroplanes are all equally as good as each other if flown within their respective performance envelopes.

 

In a single with an EFATO the choices are limited 10 deg either side of the nose and land ahead although there are those who think they can outsmart the laws of physics and turn back most of these are no longer around to tell the tale.

 

Twins give you more choices but you need to have done your homework before you shove the throttles forward, understand the single engine performance and be on top of your game, blueline is paramount if you don’t have it close the throttles and land straight ahead flirting with this will produce a departure from controlled flight very quickly and a very steep nose down attitude that will be unrecoverable from low level. If you have achieved blueline manage the engine failure as per your training and the POH most importantly fly the aeroplane.

 

3 & 4 engined aircraft are safer again performance still needs to be understood most have excess power available.

 

This accident I understand was a training flight it may very well be a mismanaged EFATO exercise these have killed more than enough instructors and students over the years, min alt is normally 300 feet or it may have been a real one from a lower altitude below blueline.

 

Sad for all concerned

Multi engined planes  more often than they should, have been pranged doing assy. Non centre aligned engines  (the most common kind) have  a yaw problem as well as a power loss problem when they lose an engine. You only have enough rudder to counter the Yaw  (keep it straight) above a certain speed Vmc (a) ,  If it yaws it also rolls and you go in as you can't control it. Engine power loss is normally  just a reduction of power to idle (with a jet) on one engine so as to produce a situation near to what it would be if the engine failed and should be able to be quickly restored to normal if something goes wrong. On a piston its set to a power which corresponds to having the engine feathered and cleaned up. Nev
