What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was on approach to the airport. It had just reduced power for descent when the pilot heard a loud bang and observed oil, from the engine, had begun to cover the windscreen. He notified the tower of a loss of oil pressure and then maneuvered for landing on 17R. The aircraft had an uneventful landing and was shut down immediately on the runway. Upon further investigation it was found that the number 6 piston rod had failed and exited the crankcase at the top side between the 3rd and 6th split line bolts. The pilot's statement says that he declared an emergency during this emergency evaluation.
