Nellis Field Airport
Aircraft Accident/Incident Report

Minden, New York 13339
Sunday, May 24, 1998 17:20 EDT

NTSB Narrative Summary Released at Completion of Accident

The flight instructor was demonstrating a soft field takeoff to the student pilot. During the takeoff, the airplane hit a dip about 100 feet down the runway, and, according to the flight instructor, it 'catapulted them into the air in an extremely nose high attitude.' The instructor thought the student pilot was frozen on the controls when the airplane did not respond to his control inputs, so he yelled, 'I've got the airplane.' The student pilot reported that the instructor pulled the nose of the airplane up, the airplane started to shake and the instructor commented on being 'behind the power curve.' The airplane went off the left side of the runway through 24 inch tall grass and struck trees before it came to rest. The flight instructor reported he did not retard the throttle during the takeoff and did not experience any mechanical problems with the airplane.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed which resulted in an inadvertent stall/mush. A related factor was the rough/uneven runway.
