1997-03-20: Cessna 421 (N4050L) — League City, TX

League City, TX, US

On March 20, 1997, a Cessna 421 (registration N4050L) was involved in an aviation accident near League City, TX. Investigators recorded the probable cause as: The pilot's failure to refuel the airplane which resulted in the loss of power to the right engine due to fuel exhaustion, and the pilot's failure to maintain airspeed during the single engine landing approach which resulted in a stall/spin. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A twin-engine airplane lost its right engine during a night instrument approach to Galveston, Texas. The pilot had reported low fuel; 7 hours 32 minutes elapsed since departure versus 7h30m endurance. The airplane entered a spin and impacted a lake. Examination found no pre-impact mechanical issues, with gear down and flaps at 15°.

Accident Sequence

The twin-engine airplane was conducting a night instrument approach to Galveston, Texas, after a non-stop flight from San Diego, California. The pilot had been cleared for the approach when he reported losing the right engine and stated that little fuel remained. Air traffic control then vectored the aircraft toward the closest airport. Radar contact was lost when the airplane was approximately one mile northeast of that airport.

A witness on the ground observed the airplane enter a spin, descend in a nose-down attitude, and strike the water near the center of a lake.

Fuel Considerations

The pilot's flight plan for the cross-country flight indicated that the airplane carried enough fuel for 7 hours and 30 minutes of flight. At the time radar contact ceased, 7 hours and 32 minutes had elapsed since departure from San Diego.

Post-Accident Examination

Examination of the wreckage revealed no evidence of any pre-impact mechanical discrepancies. The landing gear was found in the down position, the flaps were extended to approximately 15 degrees, and neither propeller was feathered.

Manual Procedure

The airplane owner's manual specified that, during a single-engine approach, the landing gear should be extended only when within gliding distance of the airfield and that flaps should be placed down only after a safe landing is assured.
