That's a sad loss; people - and the machine.

Interesting modifications to the basic Goose. See picture:

With that amount of engine overhang, it might be susceptible to engine induced aeroelastic effects like the early Electras were, but at this point sheer speculation.

Background

Found a couple of related links.
Aircraft owned by Triple S Aviation LLC
The reason it was in that part of the world:
Triple S Dubai Triple S Aviation, LLC

The conversion of this aircraft seems to be well known and is perhaps suspect.

More than likely just another engine failure on take off with a light twin. The plane was designed with a 8000 MTOW with 450HP a side. They increase the MTOW to 12,499 and put 680SHP aside. They move the engines forward for CG reasons. Takeoff and VMC in a piston Goose was around 70 mph. Probably the turbine takes off close to the same speed. But with the increase in MTOW, Engine HP, and the engine being placed around 4 feet further forward and no changes to the rudder I doubt VMC stayed at 70mph. Also seeing it is under 12,500 only one pilot required on N number. I cant speak for the Goose but on the HU-16 the PF is going to have both hands and one leg very busy with an engine out on takeoff, even with rudder boost. It is the PNF job to hit the feather button (hopefully the correct one) and adjust the working engine power as required. If directional control or roll is an issue it would be reducing power, if not, giving it as much as the PF could take and keep it flying. Off course with runway remaining or a water takeoff with no obstructions PNF just closes both.

I pretty much agree with what you have said except that these engines are much closer to the centerline compared with a more conventional Goose.See picture.

The modified aircraft with its more closely spaced engines doesn't generate such asymmetry despite its higher HP and there is probably substantial energizing of the rudder airflow from the new engine location. Also, there is a substantial dorsal fin.
To summarize, it looks like due consideration was made for the higher HP turbine engines and their effect on VMC.

I can't be sure , but the engines look like garrett's...and if that is so, there is a negative torque sensing system to immediately reduce drag if an engine fails...it is NOT the same as automatic feathering.

Do we recall the seaplane crash, CHALKS AIRWAYS, near Miami? Wing came off ...metal fatigue.

Hey man... This Goose was set to be ferried back to the States. 2 of the pilots on board were very close friends of mine and spoke with one of them yesterday. It's surreal.

Didn't Chalks in Miami lose a goose to wing failure, it was retro fitted engines as well I think??
