Narrative:
A 7,378-hour Airline Transport Pilot (ATP) reported that they had just departed the airport and established a cruise-climb, with a 752-hour private pilot at the controls, and one passenger in the rear of the airplane. During the cruise-climb the engine went to full rpm, and then the ATP noticed that the engine oil pressure indicated zero. During the attempted return to the airport, the engine seized and the private pilot turned the controls over to the ATP. The ATP executed a forced landing in a field 4-miles east of the departure airport. Examination of the engine by an NTSB investigator revealed that the oil filter was improperly installed, and the O-ring at the base of the filter was broken. Additionally, the oil filter's adapter plate was found cracked, which allowed the engine oil to be pumped overboard while in flight.

Probable Cause: A loss of engine power due to the improper installation of the oil filter resulting in oil starvation and eventual seizure of the engine. A contributing factor was the lack of suitable terrain for the forced landing.
