What happened
The pilot was operating the aircraft from the front seat despite the airplane being placarded by the Federal Aviation Administration for solo flight exclusively in the rear seat. The mission involved banner towing, and the pilot had just completed dropping off his banner in the sod area adjacent to the runway. After releasing the load, he side-stepped to the left to align with the runway centerline for landing.
Upon touchdown on the runway, the tail of the airplane lifted upward. The pilot applied throttle and pulled back on the control stick. During this maneuver, his body weight shifted forward, which caused him to inadvertently apply the brakes. This action resulted in an immediate loss of directional control. The aircraft subsequently nosed over.
The investigation
The investigation focused on the operational context of the flight and the mechanical state of the aircraft at the time of the accident. It was confirmed that the pilot was occupying the front seat, contrary to the FAA placard requirements for solo operation. The sequence of events leading to the nose-over was attributed to the pilot's physical movement and subsequent brake application during the critical phase of takeoff or landing rollout.
Findings
The primary factors contributing to the accident included the pilot's failure to adhere to the aircraft's operating limitations regarding seat occupancy. Additionally, the inadvertent application of brakes during a high-power maneuver led to the loss of control. The nose-over was a direct consequence of this loss of directional stability.
3 fatal injuries were reported among those involved in the accident. The aircraft sustained substantial damage to its structure.
