A pilot departing Albuquerque en route to Redlands via Prescott experienced tachometer fluctuations and RPM decay after adjusting propeller control. Forced landing resulted in nose-over; loose oil filter found postaccident.

Accident Overview

A pilot departed Albuquerque, New Mexico, on a flight to Redlands, California, with a planned stop in Prescott, Arizona. During the initial climb, as the airplane reached 350 feet above ground level, the pilot reduced the propeller control to a climb power setting. Shortly thereafter, the tachometer needle began fluctuating. The pilot responded by returning the propeller control to the takeoff power setting.

Engine Failure and Forced Landing

Despite the adjustment, engine RPM began to decay, making sustained flight impossible. The pilot executed a forced landing onto a rough field. During the landing roll, the airplane nosed over.

Postaccident Findings

A postaccident inspection revealed oil streaking along the entire length of the airplane. The source of the oil leak was identified as a loose oil filter. According to the engine logbook, the owner-pilot had changed the engine oil and filter two days prior to the accident.

Probable Cause
