1995-06-23: Beech 58 (N4403Q) — Air Orlando Charter, Inc. — Orlando, FL

Orlando, FL, US

On June 23, 1995, a Beech 58 (registration N4403Q) operated by Air Orlando Charter, Inc. was involved in an aviation accident near Orlando, FL. Investigators recorded the probable cause as: The engine-driven fuel pump drive coupling was rounded off and not turning the pump; the drive coupling was too short for the model fuel pump drive shaft. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.

After takeoff from runway 7, the pilot reported an engine failure. The aircraft struck a tree and crashed. Examination revealed a fuel pump drive coupling issue and non-compliance with a 1993 FAA Airworthiness Directive.

Accident Details

Shortly after takeoff from Runway 7, the pilot informed FAA controllers of an engine failure. Controllers observed the landing gear retract and then immediately extend. Witnesses saw the aircraft at tree-top level executing a turn to the north with the landing gear extended, the left engine shut down, and its propeller feathered. The aircraft descended and struck the top of a tree while wings level. It then rolled 90 degrees to the right and impacted the ground. The aircraft subsequently cartwheeled and slid backward into a tree, where it came to rest.

Engine Examination

Examination of the left engine revealed that the engine-driven fuel pump drive coupling was rounded off and not turning the pump. The drive coupling was found to be too short for the model of the fuel pump drive shaft. A 1993 FAA Airworthiness Directive that mandates checking for the proper length drive coupling had not been complied with.

Flight Manual Procedures

The aircraft's flight manual specifies that the first action to be performed by the pilot after an engine failure is to raise the landing gear. The manual also states that single-engine performance is based on the landing gear being retracted.

Probable cause

The engine-driven fuel pump drive coupling was rounded off and not turning the pump; the drive coupling was too short for the model fuel pump drive shaft. A 1993 FAA Airworthiness Directive requiring checking for proper length drive coupling had not been complied with.
