Pilot Actions
Prior to departure, the pilot did not perform any preflight performance calculations. After a run-up check of the engine, he configured the airplane for a short field takeoff, accelerated in a turn onto the turf runway, and proceeded with the takeoff.
In-Flight Observations
Once the airplane left the ground, the pilot sensed a problem but was unsure if he could land with the remaining runway. He felt the engine "was not running at full power" but could not recall any abnormal engine instrument indications or hear unusual engine sounds.
Witness Account
A witness observed the takeoff and became concerned after seeing the runway distance covered compared to the altitude achieved. The witness noticed the airplane was taking off with a tailwind, as the windsock pointed "down the runway." The witness described the engine sound as "pulling pretty hard and doing what it was supposed to."
Post-Accident Examination
A post-accident examination of the airplane revealed no evidence of any pre-impact malfunction or failure.
Runway and Obstacle Information
The runway was 2,100 feet long. Departure-end obstacles included 60-foot trees located 450 feet from the departure end. A calculation showed that, given the conditions on the day of the accident, if the airplane were loaded to its maximum gross weight and departing from a paved runway, 2,700 feet was required to clear a 50-foot barrier.
