During an introductory flight, the engine lost partial power shortly after liftoff. The CFI executed an off-airport landing; after touchdown, the left wing struck a tree. Post-accident inspection found no engine anomalies.

Flight Description

The accident flight was an introductory flight conducted by a certificated flight instructor (CFI) and a student. After the preflight inspection, the CFI and student spent time taxiing the airplane and performing ground handling exercises. Prior to takeoff, two engine run-ups were performed, and nothing unusual was noted.

Incident Sequence

Shortly after liftoff, the engine experienced a partial loss of power. The CFI determined that a straight ahead landing was not possible due to the presence of trees and homes in the area. Consequently, a left turn was initiated. The CFI checked the magnetos, fuel, and applied carburetor heat, but the engine continued to lose power.

The CFI then executed an off-airport emergency landing. Shortly after touchdown, the airplane's left wing struck a tree, resulting in substantial damage.

Post-Accident Investigation

An on-scene investigation conducted by the Federal Aviation Administration (FAA) revealed that the airplane had been fueled and no engine anomalies were found. The CFI reported that the temperature at the time of the accident was 64 degrees Fahrenheit and the dew point was 63 degrees Fahrenheit.
