N8912Q has since been reassigned. It is now registered to a different aircraft (BOEING 737-8, built 2023), which was not involved in this event.
Aircraft involved
Probable cause & findings
The pilot's inadequate preflight inspection and failure to remove the gust lock, which resulted in his loss of airplane control.
Factual narrative
On July 10, 2003, about 0600 Pacific daylight time, an Aero Commander S2R, N8912Q, experienced a loss of control during the takeoff roll at the Tulelake Municipal Airport, Tulelake, California. The airplane veered off the left side of runway 11 and came to rest upon decelerating in a soft field about 200 yards from the runway's edge. The airplane was substantially damaged, and the commercial pilot received a minor injury. The airplane was owned and operated by Macy's Flying Service, Inc., Tulelake. The accident occurred during an attempted takeoff for an agricultural flight performed under the provisions of 14 CFR Part 137. Visual meteorological conditions prevailed, and the flight was originating at the time of the accident. In the pilot's completed "Aircraft Accident Report," he indicated that during the takeoff roll he had experienced a total loss of aileron control. He also indicated that the accident could have been prevented had he performed a better preflight inspection because he would not have left the gust lock on the right aileron. The Federal Aviation Administration (FAA) inspector opined that the pilot apparently forgot to remove the right aileron to flap gust lock. He further opined that about rotation speed, the pilot would have put down some amount of flaps to aid his takeoff, and the airplane veered off the runway. The airplane's left wing tip struck the ground, and the airplane slid across the ground until coming to a stop in the adjacent field. The pilot lost control of the airplane during the ground roll portion of takeoff. The airplane veered off the runway and decelerated in an adjacent soft field. The agricultural flight was originating at the time of the pilot's 0600 departure. The pilot acknowledged that had he performed a better preflight inspection, he would not have left the gust lock on the right aileron. During the takeoff roll, the airplane's wingtip contacted the runway. Thereafter, the airplane slid across the ground and came to a stop in an adjacent field.
