On the landing roll out following an emergency landing, the nose landing gear dug into the soft dirt and the airplane nosed over. During cruise, the CFI asked the student if he heard knocking. The student replied that he did hear the knocking. Both pilots saw the oil pressure gage reading zero, simultaneously the knocking increased, and then the engine quit. The external examination of the engine revealed that the bottom of the fuselage, firewall, and the rear of the engine were coated with oil. The inspection further revealed that the oil filter had not been tightened or safety wired to the engine. Review of the engine logbook disclosed that an oil change was completed the day prior to the accident.
Probable Cause: Failure of company maintenance personnel to properly install and safety wire the oil filter, which subsequently lead to a loss of engine power.
