Merpati Nusantara Airlines Flight 9760D

Merpati Nusantara Airlines Flight 9760D was a domestic commercial passenger 50-minutes flight, flying from Sentani Airport in Papua's Province Jayapura to Oksibil Airport in Oksibil, Indonesia operated by a de Havilland Canada DHC-6 Twin Otter 300.

On Sunday, August 2, 2009, while carrying fifteen people over Papua, the aircraft went missing en route.

Indonesian Investigation Agency, NTSC released the final report and concluded that the cause of the crash was controlled flight into terrain (CFIT).

The pilots did not maintain visual flight rules while flying below lowest safe altitude, thus impacting terrain.

Another aircraft in the vicinity informed Flight 9760D that the weather around Oksibil Airport was partly cloudy.

The aircraft involved in the accident was a de Havilland Canada DHC-6 registered as PK-NVC with serial number 626.

In the report, Merpati Nusantara Airlines were stated not to have fully co-operated with the NTSC as they had not provided the investigators full details of the crew's line checks and training undertaken.

The weather in the area of the flight was reported by local villagers to have been mostly clear in the valleys, with clouds on the mountains and slopes.

Indonesian Civil Aviation regulations required that a serviceable CVR was to be fitted to the Twin Otter aircraft.

About 20 minutes before the impact, the pilots were discussing the area they were flying over, and made comments about the local inhabitants.

However, ten minutes before impact the pilot in command mentioned climbing to 10,000 feet (3,000 m), and stated "if we cannot go visual I will turn left".

The cockpit conversations did not exhibit any signs of stress or concern until 2 minutes before the impact, when the copilot mentioned haze and asked the pilot in command if he could see.

From the pilots' comments and the wreckage trail, the investigation determined that the aircraft was banking left at the time of impact.
