What happened
During the initial phase of takeoff, the airplane achieved lift-off at a speed estimated between 60 and 65 miles per hour. Once airborne, the aircraft was unable to establish a positive rate of climb. Instead of ascending, it descended immediately and impacted trees located just beyond the departure end of the runway.
The investigation noted that the aircraft's best angle of climb speed is 70 mph, while its best rate of climb speed is 84 mph. The impact suggests the pilot may have been operating below these optimal performance envelopes during the critical takeoff phase.
The investigation
Review of the pilot's qualifications revealed a total flight time of 111 hours. Of this total, only 47 hours were logged specifically in this make and model of aircraft. This limited experience in the specific type may have contributed to the inability to maintain adequate climb performance during departure.
