Date & Time: 02/17/2018, 1500 MST
Registration: N904DB
Aircraft: BLACK DONALD COZY III
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On February 17, 2018, mountain standard time, a Cozy III experimental homebuilt airplane, N904DB, registered to the pilot, sustained substantial damage during a forced landing after an in-flight propeller gearbox failure at the Mid Valley Airpark (E98), Los Lunas, New Mexico. The commercial pilot, who was the sole occupant, was not injured. Visual meteorological conditions prevailed and a flight plan was not filed. The local flight was being conducted under the provisions of Federal Code of regulations Part 91. The flight originated from E98 about 1400.

After flying uneventful for about 1 hour in the local area, the pilot set up for landing at E98. On downwind for runway 36, the propeller seized and the pilot executed a forced landing to runway 36. While turning on final approach, the pilot slightly overshot the runway and touched down hard on the right edge of the runway. The landing gear were sheared upon touchdown and the airplane sustained substantial damage to the right wing and center fuselage section.

Upon inspection of the airplane, it was discovered that the propeller gearbox was seized. Review of logbooks indicated that the airplane's total hours were about 13.4 since it's initial airworthiness certificate was issued on November 21, 2011.

Aircraft:  DONALD BLACK, COZY III
Aircraft Damage: Substantial
Defining Event: Fire/smoke (non-impact)

Analysis


While taxiing after landing, the engine lost power, and the pilot turned the airplane off the runway. The pilot exited the airplane and noticed smoke at the rear of the airplane near the engine. The pilot attempted to extinguish the fire; however, his efforts were unsuccessful, and the airplane was consumed by the fire. At the time of the accident, the airplane had accumulated 4.9 flight hours. Postaccident examination of the airplane found loose B-nuts on two fuel lines and one oil line. An oil streak was noted on the runway surface, and no oil was found in the engine. The pilot stated that the fire likely resulted from oil leaking onto the hot turbocharger.


Probable Cause and Findings


The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A loose oil line, which allowed oil to leak onto the hot engine turbocharger and resulted in a fire.
