Circumstances:
On 11 August 2009, a de Havilland Canada DHC-6 Twin Otter aircraft, registered P2-MCB, with two pilots and 11 passengers, was being operated on a scheduled regular public transport service from Port Moresby to Kokoda Airstrip, Papua New Guinea (PNG). At about 1113, the aircraft impacted terrain on the eastern slope of the Kokoda Gap at about 5,780 ft above mean sea level in heavily-timbered jungle about 11 km south-east of Kokoda Airstrip. The aircraft was destroyed by impact forces. There were no survivors. Prior to the accident the crew were manoeuvring the aircraft within the Kokoda Gap, probably in an attempt to maintain visual flight in reported cloudy conditions. The investigation concluded that the accident was probably the result of controlled flight into terrain: that is, an otherwise airworthy aircraft was unintentionally flown into terrain, with little or no awareness by the crew of the impending collision.
Probable cause:
• Visual flight in the Kokoda Gap was made difficult by the extensive cloud coverage in the area.
• The crew attempted to continue the descent visually within the Kokoda Gap despite the weather conditions not being conducive to visual flight.
• It was probable that while manoeuvring at low level near the junction of the Kokoda Gap and Kokoda Valley, the aircraft entered instrument meteorological conditions.
• The aircraft collided with terrain in controlled flight.
