Probable cause & findings
A FAILURE OF THE RIGHT ENGINE PROPELLER GOVERNOR OIL LINE WHICH WAS THE INCORRECT LINE AND IMPROPERLY INSTALLED BY MAINTENANCE PERSONNEL.
Factual narrative
On April 17, 1994, at 2130 mountain daylight time, a Beech 95, N3051, sustained substantial damage from an engine fire which occurred during landing roll at Greeley-Weld County Airport. The pilot and passenger were not injured. Visual meteorological conditions prevailed and no flight plan was filed. The flight originated from Broomfield, Colorado, approximately 1 hour prior to the accident. Examination by an FAA inspector revealed that the propeller oil governor line had separated on the right engine. Further investigation provided information that the line and routing were not in compliance with Airworthiness Directive AD 90-04-06. A copy is attached. DURING LANDING ROLL, THE RIGHT ENGINE CAUGHT FIRE. EXAMINATION PROVIDED EVIDENCE THAT THE PROPELLER GOVERNOR OIL LINE WAS IMPROPER AND HAD BEEN ROUTED IMPROPERLY. THE OIL LINE SEPARATED AND OIL FROM THE LINE CAUGHT FIRE. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
