What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On final approach to 16, the touch down was normal and on the runway centerline. As the pilot started to apply the brakes, the seat slipped rearward, causing the pilot to apply more pressure to the left brake. This caused the aircraft to veer off onto the edge of the runway and strike a runway light fixture with the propeller blade tips. There was no other damage to the aircraft. The seat tracks had been recently replaced. Both the student pilot and instructor were counseled.
