Aircraft Accident/Incident Report
Durango, Colorado 81301
Saturday, March 13, 1999 15:00 MST
NTSB Narrative Summary Released at Completion of Accident
The airplane was cruising at 41,000 feet msl when the crew noticed low fuel flow and low EGT readings on the left engine. They further noted that the oil temperature and fuel temperature gauges began to rise on the same engine. They requested clearance to descend, and as the captain reduced the throttle, the fire light on the left engine illuminated. He pulled the left fire T-handle and the fire light extinguished. The crew secured the engine, requested emergency equipment be standing by in Durango, and landed without further incidence. Postaccident examination revealed that the lower forward area of the left engine nacelle was damaged by fire. Further examination revealed that an electrical wire coming from an alternator in the engine had been chaffing against the number four fuel line.
NTSB Probable Cause Narrative
The failure of the number four fuel line. Factors were the chaffing of the alternator's electrical wires on the number four fuel line, and the subsequent fire in the number one engine nacelle.
