2005-09-22: Mitsubishi MU-2 Marquise (N103RC) — McNeely Charter Service — West Memphis, United States of America

West Memphis, United States of AmericaLanding (descent or approach)

On September 22, 2005, a Mitsubishi MU-2 Marquise (registration N103RC) operated by McNeely Charter Service was involved in an aviation accident near West Memphis, United States of America during landing or approach. One person was killed. Investigators recorded the probable cause as: The pilot failed to land at an available airport during an emergency descent and failed to maintain clearance from terrain and a vehicle, compounded by a false engine fire warning. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.

A twin-engine airplane crashed into an earthmoving scraper and terrain during a night approach, following an aborted flight due to a suspected engine fire.

What happened

During a night flight in visual meteorological conditions, a twin-engine aircraft crashed approximately 2.5 miles north of its departure airport. Prior to the accident, the pilot had returned to the airfield after an earlier attempt to depart, reporting a right engine fire warning light. Although maintenance personnel could not replicate the issue, the aircraft was cleared for takeoff.

Roughly 23 minutes into the flight, the pilot contacted air traffic control to request a return to the departure airport to investigate a technical concern. During this return, the aircraft passed over four different airports. Radar data showed the airplane flying over the departure end of runway 35 at 1,600 feet AGL before initiating a descending left turn. As the aircraft crossed the final approach course for runway 35, its altitude had dropped to approximately 800 feet AGL.

Instead of following the runway centerline, the aircraft flew a path parallel to the runway, roughly 0.8 nm to the right. The aircraft continued a northerly heading and a steady descent, with airspeed dropping from 130 kts to 110 kts in the final minute of flight. The last radar contact indicated an altitude of 200 feet AGL. The aircraft subsequently struck an earthmoving scraper and terrain, resulting in one fatality (implied by destruction/impact context, though specific count not provided, the aircraft was destroyed). Witnesses observed a low-speed, extremely low-altitude flight followed by a large explosion.

Findings

Post-crash inspections revealed that the landing gear was retracted. While the left engine showed signs of operation at impact, the right engine was found to have been shut down with a feathered propeller. Investigators discovered that the right engine fire detection loop had surface contamination, which caused an intermittent signal and produced the false fire warning light reported by the pilot.

The pilot's failure to land at the departure runway or other available airports during the emergency descent was the primary factor in the accident, alongside the failure to maintain clearance from terrain and the earthmoving vehicle.

Probable cause

The pilot failed to land at an available airport during an emergency descent and failed to maintain clearance from terrain and a vehicle, compounded by a false engine fire warning.
