Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering over wildlife, which resulted in an uncontrolled descent and subsequent collision with trees. A factor contributing to the accident was an inadvertent stall.

Analysis

The private certificated pilot was maneuvering the airplane in the vicinity of a moose with an airspeed of about 50 to 60 knots on a CFR Part 91 personal flight, when he inadvertently stalled the airplane. The pilot said that there were no mechanical problems with the airplane. The airplane received structural damage to wings and fuselage when it collided with trees.

Factual narrative

On September 21, 2005, about 1910 Alaska daylight time, a tundra tire-equipped Champion 7EC airplane, N4384C, sustained substantial damage when it collided with trees during an uncontrolled descent while maneuvering in a remote area, about 12 miles north-northwest of Wasilla, Alaska. The airplane was being operated as a visual flight rules (VFR) local area personal flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by the pilot. The private certificated pilot, and the sole passenger, received serious injuries. Visual meteorological conditions prevailed. The flight originated at the Wasilla Airport, Alaska, and no flight plan was filed.

During a telephone conversation with a National Transportation Safety Board (NTSB) air safety investigator (ASI), on September 26, the pilot reported that he was maneuvering the airplane in the vicinity of a moose with an airspeed of about 50 to 60 knots. The pilot indicated that the left wing stalled, and the airplane then descended into the trees. The passenger notified search and rescue personnel. The pilot said that there were no mechanical problems with the airplane. The airplane received structural damage to wings and fuselage.
