Incident Overview
The pilot of a single-engine airplane conducted a short-field takeoff from a 2,350-foot runway bordered by trees at the departure end. Before departure, an engine run-up showed no anomalies, and the pilot set the wing flaps to 10 degrees for takeoff.
Sequence of Events
Immediately after becoming airborne, the pilot retracted the flaps. The pilot reported feeling as though the airplane's nose was "pushed down." The airplane subsequently contacted trees at the end of the runway and then impacted the ground.
Damage
The accident resulted in substantial damage to the fuselage, both wings, and the engine firewall.
Postaccident Examination
A Federal Aviation Administration inspector examined the airplane and engine after the accident. No anomalies were found that would have precluded normal operation.
Relevant Handbook Guidance
According to the airplane owner's handbook, when operating from short runways, takeoff distances can be reduced appreciably by lowering flaps to 25 degrees. The Airplane Flying Handbook (FAA-H-8083-3A) states that on short-field takeoffs, the landing gear and flaps should remain in the takeoff position until clear of obstacles and best rate of climb has been established. It further advises raising the flaps in increments to avoid a sudden loss of lift.
