What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On may 19, 2004, while enroute from buffalo airport (1E7) to plainview (pvw), Texas, on a VFR cross country instructional flight cruising at 5500 feet MSL, Beech musketeer N6943Q lost power at approximately 1920 CDT, due to separation of the propeller from the aircraft. Aircraft was approximately one mile south and less than one mile west of vaughn airport (29F) and 13.95 miles north of pvw. The flight instructor stated that oil was observed on the windshield just prior to separation of the propeller from the aircraft. The departure of the propeller was observed by the flight instructor, stating that it departed to the right of the aircraft. The engine then oversped to approximately 3500 RPM and just as the instructor was reaching for the throttle to idle back, the engine quit. At approximately 5000 feet MSL, the flight instructor initiated a dead stick landing into 29F. The instructor turned the aircraft east and then entered a downwind leg for runway 17. The aircraft landed without incident with no damage other than the broken crankshaft. There were no injuries to the flight instructor or the student pilot. Examination of the crankshaft revealed failure aft of the propellerflange. The propeller was not found.
