Casualties: Fatalities: 0 / Occupants: 11
Component Affected: Aircraft landing gear (main and nose).Aircraft landing gear (main and nose).
Investigating Agency: NTSCNTSC
Category: Serious incident
A Cessna Grand Caravan operated a non-scheduled flight from Sentani Airport to Mulia Airport. Before the aircraft entered the final approach, the pilot received information indicating clear runway conditions ? specifically, the final and gap area was unobstructed, with a westerly wind of 8 knots. The Mulia Airport was located at approximately 5,500 feet elevation and 10% up slope runway, which was typically obscured by clouds during the afternoon hours. Upon touchdown, the aircraft bounced and floated, then veered to the left. The pilot recovered by applying reverse thrust and brakes, but the veering continued. The aircraft ultimately stopped on the left side of the runway with damaged main and nose landing gear. The engine was shut down, and passengers were disembarked normally. No injuries occurred.A Cessna Grand Caravan operated a non-scheduled flight from Sentani Airport to Mulia Airport.

Description

The Cessna Grand Caravan operated on a non-scheduled flight from Sentani Airport to Mulia Airport. Before the aircraft joined the initial approach pattern to Mulia the pilot was able to contact Mulia AFIS and received information which included that on the final and gap area which was about 2 nm of runway 08 were clear and the wind was westerly 8 knots. The Mulia Airport was located at approximately 5,500 feet of elevation and 10% up slope runway which normally covered by clouds during the afternoon hours. The aircraft touched down within the touchdown point of runway 08, then bounced and floated. After a second touchdown the aircraft started to veer to the left, the pilot recovered by applying reverse thrust and brakes, however the aircraft continued to veer to the left. The aircraft stopped on the left side of the runway with left main and nose landing gear damaged and sunken into soft soil. The engine was shut down and the passengers disembarked the aircraft normally. No persons were injured. The investigation concluded that the contributing factors of this serious incident were; – The illusion of the runway condition resulted to the pilot misinterpret the situation and late to flare on touchdown and bounced. – The recovery action performed by the pilot resulted to the force that moved the aircraft further to the left and difficult to recover back to the runway centerline.
