NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot of the unregistered homebuilt aircraft was departing in strong, gusty winds that were reported to be constantly changing direction. After lifting off about halfway down the 3,800 feet runway, the aircraft appeared to remain less than 20 feet above the ground as it continued to accelerate toward the departure end. As it neared the trees off the departure end of the runway, it appeared that the aircraft started to climb. But, its right wing clipped a tree as the pilot attempted to maneuver into an open corridor formed by a nearby railroad track. At the time of the accident, the density altitude was about 5,300 feet, and a pilot that had just departed said that the air was very bumpy just above treetop level. No evidence of anomalies or malfunction were found in the airframe or engine.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to maintain clearance from trees located off the departure end of the runway. Factors include strong, variable, gusty winds, terrain-induced turbulence, a high density altitude, and trees off the departure end of the runway. Full narrative available
