Indonesian investigators have detailed an extraordinary accident in which a Merpati Nusantara de Havilland Canada Twin Otter bounced on touchdown, veered off the runway struck trees and spun while landing at Dabra in Papua.

The twin-engined aircraft had been arriving as flight MZ9782D from Jayapura on 17 October, with 13 passengers and three crew members on board.

It touched down on Runway 24 - which requires a visual approach - and "experienced bouncing" for 175m (570ft), said the Indonesian National Transportation Safety Committee.

The Twin Otter (PK-NUH) then veered off the right side for 120m, and its right wing struck banana trees.

Some 18m from the end of the runway, investigators found a "scoured mark" on the asphalt indicating that the aircraft had conducted a "quick and deep" turn - a ground loop - on its right main wheel.

This caused the right tyre to burst, damage to the left main gear, and twisting in the lower forward fuselage, and resulted in the aircraft coming to rest having spun more than 180°, 36m from the runway end.

None of the 16 occupants on board was injured. The NTSC, which has yet to reach conclusions on the accident, added: "There was some banana tree damage, mostly due to [being] hit by [the] aircraft's right wing."
