Aviation Accident Summary ANC07LA079

Big Lake, AK, USA

Aircraft #1

N82192

Aeronca 7AC

Analysis

The student pilot said that while en route to his intended destination airport, he decided to look at some lake front property. He said that as he made a right downwind turn over the lake, about 500 feet agl, the right wing stalled, and the airplane descended vertically. During the student's effort to recover from the stall, the right wing struck a tree on the lake's shoreline, and the airplane came to rest about 30 feet from shore. The student pilot reported there were no preaccident mechanical problems with the airplane.

Factual Information

On August 10, 2007, about 1700 Alaska daylight time, a wheel-equipped Aeronca 7AC airplane, N82192, sustained substantial damage following a loss of control, and subsequent collision with trees, while maneuvering about 2 miles northeast of Big Lake, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight under Title 14, CFR Part 91 when the accident occurred. The solo student pilot sustained minor injuries. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed. The flight originated at the Palmer Airport, Palmer, Alaska about 1600, and was en route to the Willow Airport, Willow, Alaska. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on August 12, the student pilot reported that that while en route to his destination airport, he elected to fly over a lake to view some property. He said that as he made a right, downwind turn, the right wing stalled, and the airplane descended nose first. He reported that he was able to level the wings just before the airplane's right wing struck a large tree, which pivoted the airplane to the right. The airplane descended vertically and came to rest in the lake, about 30 feet from the shoreline. The student pilot reported that there were no preaccident mechanical anomalies with the airplane.

Probable Cause and Findings

The student pilot's failure to maintain adequate airspeed to avoid an inadvertent stall while maneuvering.
