Does beg the question why de Havilland didn't take this problem and solution on board and pass the solution on to other Otter operators.....??
Particularly since DHC had known about it since the early 70s. A pilot of a Series 100, belonging to an oil company that I worked for, did the same thing on takeoff out of Edmonton Municipal Airport and made an immaculate forced landing into the only available open ground - a schoolyard. Luckily, it was early morning, before school time.
When I subsequently flew on this aircraft, the fuel levers were secured in the On position with bungee cords that hooked around the levers.
I am surprised the Air Maldive aircraft didn't have this mod, since they come from Ken Borek in Calgary and you would think the Canadian Twin Otter operators would be very aware of the previous incident.
