What happened
The accident occurred during the initial phase of a takeoff operation. As the aircraft began its takeoff roll on the runway, the pilot experienced a sudden loss of directional control. The airplane subsequently departed the paved surface, running off the side of the runway and coming to rest in a nose-over attitude.
The investigation
Post-accident analysis was severely limited by the circumstances surrounding the event. The accident was not reported until October 1982, nearly a year after the incident occurred. By the time investigators could examine the aircraft, it had already undergone repairs. Consequently, the specific component responsible for the loss of control—the tailwheel steering spring—was no longer available for forensic examination or failure analysis.
Findings
Based on the pilot's statement, the tailwheel steering spring had failed prior to or during the takeoff roll. This mechanical failure prevented proper steering authority, leading directly to the runway excursion. The lack of physical evidence meant that the exact nature of the spring's failure could not be confirmed mechanically.
Safety message
This incident highlights the critical importance of timely accident reporting and preserving the aircraft in its post-accident state for investigation. Delayed reporting can result in the loss of vital evidence, such as failed components, which hinders the ability to determine root causes and prevent similar occurrences.
