NTSB summary

HISTORY OF FLIGHT On July 12, 2002, about 1145 Alaska daylight time, a float-equipped de Havilland DHC-2 airplane, N3129F, was destroyed during an in-flight collision with terrain, about 6 miles east of Port Alsworth, Alaska. The airplane was being operated by Bigfoot Air, Anchorage, Alaska, as a visual flight rules (VFR) charter flight under Title 14, CFR Part 135, at the time of the accident. The commercial pilot and the three passengers were fatally injured. Visual meteorological conditions prevailed, and a VFR flight plan was filed.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (I

Probable cause
