On September 20, 1986, a DE Havilland DHC-3 (registration N83U) operated by Bering Air Service was involved in an aviation accident near American River, AK. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
After landing on a 1200 ft gravel bar, the pilot loaded the aircraft and attempted takeoff with less than takeoff flaps due to crosswind. Following lift-off, a downdraft was encountered, and the aircraft failed to clear a 20 ft dirt bank, resulting in impact and occupants exiting.
Landing and Loading
The pilot landed the aircraft on a 1200 ft gravel bar. After landing, he paced off the available area and estimated the load to be picked up. The aircraft was then loaded with the cargo.
Takeoff Attempt
Due to a crosswind, the pilot used less than takeoff flaps for departure. He began the takeoff roll. After the aircraft lifted off, it "seemed to hit a downdraft." The pilot then selected takeoff flaps and initiated a slight turn to gain more room to clear a 20 ft bank of dirt.
Collision with Terrain
The aircraft was unable to clear the dirt bank. It struck the bank and subsequently came to rest on the tundra. The occupants exited the plane after the aircraft came to a stop.
