Circumstances
During the takeoff roll, the pilot discovered that the control wheel would not move aft. Consequently, the pilot decided to abort the takeoff. In the process of aborting, the pilot reduced engine power and extended the flaps to the full position. This action caused the airplane to porpoise and veer off the runway. The nose gear subsequently collapsed.
Post-Incident Examination
An examination of the wreckage was conducted to determine the cause of the control wheel restriction and any other contributing factors. The inspection did not disclose any evidence of mechanical malfunctions in the aircraft's flight control systems or other components.
Handbook Guidance
The Pilot's Operating Handbook (POH) for the airplane specifies that during an aborted takeoff, the flaps should be retracted. The pilot's action of extending full flaps was contrary to the published procedure.
Conclusion
The incident involved a takeoff abort due to an inability to move the control wheel aft. The subsequent flap extension led to porpoising and a runway excursion resulting in the collapse of the nose gear. No mechanical issues were identified during the post-incident examination.
