Narrative:A Douglas C-47B, XV-NIE, operated on a passenger flight from Saigon-Tan Son Nhat Airport to Quang Ngai Airport, Vietnam.
The flight took off at 00:35 with an ETA at Quang Ngai of 02:50 hours. While en route, the Quang Ngai was flooded. Attempts by Saigon ACC to contact the aircraft after 02:00 hours all failed.
The aircraft was found to have struck the nearly vertical wall of a mountain, at an elevation of about 400 m, 20 km NNW of Quang-Ngai. The location of the wreckage suggested that the flight crew got lost and flew too low in a mountainous area while attempting to reach the nearby airport of Chu Lai, 8 km ENE of the wreckage site.
Probable Cause:Probable Causes:
Pilot factor - the pilot-in-command flew VFR in IMC in an attempt to divert to an alternative airport.
Contributing factor - Adverse weather conditions.
VFR flight in IMC
Controlled Flight Into Terrain (CFIT) - Mountain
