What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was operated in slush during high altitude, off airport landing training. It is believed that the brakes accumulated water during taxi and froze during the return flight to 4SD. The temperature at Reno/Stead Airport at the time of the incident was 37 degrees. Upon landing, the frozen brakes impeded wheel rotation and the aircraft nosed over. Note: the aircraft was below gross weight and within center of gravity limits at the time of the incident.
