Incident Overview
During a takeoff sequence, the pilot of another aircraft waiting for departure notified the pilot of the accident airplane that a fire was visible on the right engine. The accident pilot acknowledged the fire and proceeded to shut down the right engine. Airport personnel then used multiple hand-held fire extinguishers to successfully extinguish the engine fire.
Examination Findings
An internal inspection of the engine compartment revealed fire damage concentrated in the area surrounding the engine-driven fuel pump. Adjacent to this fuel pump assembly was a hydraulic supply line. Further examination disclosed that both the hydraulic supply line and the engine-driven fuel pump were found to be loose within the engine compartment.
Maintenance Records Review
A review of the airframe and engine maintenance log books indicated that Airworthiness Directive (AD) 98-18-12 was applicable to the aircraft. This AD mandates that the engine-driven pump assembly be re-torqued to specified standards, with the stated purpose of preventing leaks that could potentially lead to engine failure or an engine fire. The log book review revealed that compliance with this airworthiness directive had not been documented.
