NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airline transport certificated pilot was departing toward the north from a gravel area along a remote creek. The takeoff area was oriented north/south, and was about 800 feet long, and about 100 feet wide. The pilot indicated the wind was variable, about 7 knots. About 25 feet after liftoff, the right main landing gear tire struck about a 2 foot high embankment. The airplane settled onto the gravel bar and came to a stop. The pilot said that an observer on the ground reported to him that the wind appeared to switch to a tailwind during the takeoff run. The airplane was retrieved from the scene by helicopter. The pilot of the helicopter reported that when he arrived at the scene, he observed the right main landing gear strut and tire lying in a small creek, separated from the fuselage, between what appeared to be the takeoff point, and the airplane's point of rest.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's selection of unsuitable terrain for takeoff, and his inadequate evaluation of the wind conditions, which resulted in a collision with an embankment during takeoff-initial climb. Factors contributing to the accident was the presence of a sand embankment, and a tailwind.
