Dinjan

While overflying the north of Burma, while on a cargo flight from Kunming to Dinjan, the was able to send a brief mayday message informing they were attacked by the pilot of a Japanese fighter. The aircraft crashed in flames near Sumprabum, some 120 km north of Myitkyina. All three occupants were killed.

While cruising in the Fort Hertz Valley, the aircraft was hit by enemy fire. The left engine caught fire, exploded and detached, shearing off a part of the wing. Out of control, the aircraft dove into the ground and crashed in flames. All three crew members were killed.

One hour into the flight, the crew encountered bad weather and severe icing conditions. While the aircraft continued to lose altitude, pilots realized they were facing a mountain. The captain made a sharp turn to the right when the left wing hit a rocky peak. The aircraft stalled and crashed at an altitude of more than 4,000 metres above MSL. Despite their injuries, both pilots managed to escape and to find help. However, the aircraft was destroyed and the radio navigator was killed.

En route from Kunming to Dinjan, while carrying a load of tin bars, the crew encountered poor weather conditions with low visibility due to heavy snow falls and turbulence. The airplane failed to arrive at destination and may have crashed somewhere in the region of Fort Hertz. Lost without trace.

The airplane was performing a cargo flight from Kunming to Dinjan, carrying a load of tungsten and three crew members. Due to the presence of Japanese forces along the normal route, the crew decided to follow another route passing over the Pianma Pass. In low visibility due to snow falls, the captain reduced his altitude to maintain a visual contact with the ground when the airplane contacted trees and crashed in a wooded area located near the Pianma Pass, at the border between China and Burma. All three crew members were killed. In October 1996, the wreckage was found by hikers.
Crew:
Jim Fox, pilot,
L. Thom, copilot,
K. Wong, radio operator.

The airplane departed Dinjan Airport at 1330LT on a routine flight to Fort Hertz, Burma. About 30 minutes later, it was spotted by the pilot of a Hudson flying at an altitude of 7,000 feet near the city of Kanku, Arunachal Pradesh. As the aircraft failed to arrive at destination, SAR operations were initiated but eventually suspended as no trace of the airplane nor the crew was found. The wreckage was found on 25 December 2017 at an altitude of 10,412 feet some 5 days walk northeast of the locality of Roing.

A load consisting of ammunition and fuel drums was dropped over Kunming. The airplane failed to return to base in Dinjan, Assam, and was missing. SAR operations failed to find any trace of the aircraft nor the crew. The wreckage was eventually found in 2011 on the slope of a 4,084 metres high mountain located 15 km northwest of Dali.

The airplane crashed on landing at Dinjan Airport and was damaged beyond repair. There were no casualties.

The crew was performing a local training flight at Dinjan Airport after the airplane was recently delivered to the CNAC. During the takeoff run on a 600 metres long gravel runway, the captain realized he was unable to take off within the remaining distance available. He increased engine power but at liftoff, the airplane impacted trees, stalled and crashed, bursting into flames. Both pilots were injured while the aircraft was destroyed by a post crash fire.
