What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The instructor and student were on a training flight working on an additional airplane asel rating. The student is a helicopter pilot and was working on transitioning to airplane. The student was flying the aircraft and was approaching at a faster than normal approach speed and touched down approximately half way down the runway. The instructor took over the controls and maintained heavy braking action after touchdown until running off the runway and contacting the fence with the nose cone of the airplane.
