What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was landed 1/3 to 1/2 way down the runway by the second pilot receiving instruction in the aircraft. After landing, the aircraft began skidding in an attempt to stop on the remaining runway. The instructor/pic intervened, and in the process of stopping the aircraft, the propeller struck the runway surface due to a ditch/depression in the runway near the end.
