Aircraft Accident/Incident Report
Gaithersburg, Maryland 20879
Monday, June 28, 1999 10:05 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot flew a 30-minute flight, landed, and taxied back for another takeoff. The airplane began the takeoff roll at the maximum allowable gross weight. The pilot rotated at 50 knots, 5 knots below the manufacturer's recommended rotation speed. The airplane pitched up and rotated to the left. The pilot said he maintained full power and attempted to regain directional control. He said, 'I did not want to change the throttle; I wanted to fly the airplane out of trouble.' The airplane departed the left side of the runway and collided with trees. Examination of the airplane revealed the elevator trim was set in the full nose-up position. The pilot reported there were no mechanical deficiencies with the airplane.
NTSB Probable Cause Narrative
was the pilot's failure to obtain the proper rotation speed and his subsequent loss of directional control. A factor in the accident was the improper setting of the elevator trim.
