Accident & incident history

2023-12-08 Accident · McGregor, TX Damage: Substantial NTSB · CEN24LA061
Reported aircraft: Cessna 421C
Probable cause: The failure of the spring pin in the right propeller governor, which precluded the pilot from controlling the propeller pitch to maintain engine rpm, resulting in a loss of engine thrust, excessive drag, and the subsequent forced landing to a field.
