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. The flight originated at the Lake Hood Seaplane base, Anchorage, about 1045, and was bound for the Rainbow Point Lodge on Lake Iliamna, about 225 miles southwest of Anchorage.
The commercial pilot of the float-equipped airplane was transporting passengers to a lodge at a remote lake. When the airplane did not arrive at the lake, a search was initiated, and two days later the wreckage of the airplane was located on the side of a box canyon about the 2,400 foot elevation level. The canyon is oriented approximately east-west, and the wreckage was distributed along a 100 foot debris field on the north flank of the canyon. Ground scars and wreckage distribution were consistent with the airplane impacting terrain in a steep left bank while executing a turn to reverse direction. No evidence of any preimpact mechanical anomalies was discovered.
Probable Cause: The pilot's failure to maintain clearance from terrain while maneuvering inside a box/blind canyon, resulting in an in-flight collision with terrain. A factor contributing to the accident was the box/blind canyon.
