Taylorcraft BC12 D accident near Santa Teresa, New Mexico, June 10, 2018

The NTSB's narrative final · quoted from the NTSB record

The pilot reported that, during a touch-and-go landing in the tailwheel-equipped airplane, he felt an "unusual mechanical sensation," but was able to maintain directional control and continued the takeoff. During his second landing approach, the airplane “aggressively weathercocked” into the wind on short final approach and the airplane touched down tailwheel first. During the landing roll, the airplane started to veer left, and the pilot was unable to correct with rudder input. The airplane continued off the left side of the runway and nosed over, resulting in substantial damage. After the accident, the pilot noted that the left rudder spring had disconnected from the arm of the steerable tailwheel and the safety wire was missing. The pilot reconnected the spring before the airplane could be examined; whether the tailwheel spring contributed to the loss of control could not be determined. The recorded weather conditions about the time of the accident included a left quartering tailwind at 6 knots with gusts to 13 knots for the landing runway.
