Beschrijving:
The DHC-6-100 Twin Otter aircraft, VH-TGR, was scheduled to operated Flight 1369 from Mt. Hagen in the Western Highlands of Papua New Guinea at 06:30 hours.
The aircraft left Mt. Hagen at 06:39 hours and proceeded uneventfully through the scheduled airports as far as Goroka which was reached at 08:20 hours. The aircraft took off from Goroka at 08:52 hours with nine passengers, including four children, on board.
The flight plan for this sector indicated that the aircraft would take 15 minutes to fly the 25 miles from Goroka to Kainantu and the proposed cruising level was 7,500 feet above mean sea level or approximately 1,500 feet above the general level of the en-route terrain.
Witness evidence indicates that the aircraft encountered increasing cloud and a lowering cloud base as it approached Kainantu. It was seen flying at low altitude just below the cloud base.
It struck the tops of trees and fell into the lower area of a grassy hollow.
There was no outbreak of fire.

Probable Cause:

CAUSE: The probable cause of the accident was that the pilot persisted with such determination or confidence in his attempts to reach his destination in the face of deteriorating weather conditions, that he did not ensure he could safely discontinue the approach at any time and still maintain visual reference to the significant terrain.
