Accident Summary
During the takeoff ground roll, the student pilot was unable to raise the elevators. The pilot aborted the takeoff, but the remaining runway length was insufficient to bring the airplane to a stop on the runway. The airplane overran the runway, and upon entering rough and uneven terrain, the nose gear collapsed.
Postaccident Examination
A postaccident examination revealed that the horizontal 'T' bar had jammed against the attitude indicator hoses. This jamming inhibited rearward movement of the flight control wheel. The vacuum hoses and the avionics installation box brackets exhibited numerous rubbing and chafing signatures, indicating contact between components.
Maintenance History
A 100-hour or annual inspection had been accomplished two months before the accident. The airplane accrued 99 flight hours since that inspection.
