Okeechobee, United States of AmericaLanding (descent or approach)

On January 5, 1994, a Beechcraft 90 King Air (registration N230TW) operated by Kimura International was involved in an aviation accident near Okeechobee, United States of America during landing or approach. 10 people were killed. Investigators recorded the probable cause as: The pilot's improper remedial action concerning a right engine power anomaly, and his failure to maintain adequate airspeed during go-around from an aborted precautionary landing, which resulted in a loss of aircraft control and an uncontrolled descent. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 1 related events involving the same aircraft type or operator are linked below.

A multi-engine aircraft crashed while attempting a precautionary landing on a road after engine trouble, following a failed search for an airport. The pilot reported indication and engine problems. Examination revealed a right engine fuel control bearing failure and maintenance discrepancies.

Incident Overview

A pilot, who may have been a pilot-rated passenger, reported an indication problem with the aircraft and stated an intention to land at Okeechobee. However, the pilot could not locate the airport. Subsequently, engine trouble was reported, and the pilot indicated an attempt to land on a road. The aircraft circled the area and approached a dirt road with its landing lights illuminated. A car was traveling on the road in the opposite direction. The airplane began to climb and initiated a left turn. It then rolled into a steep right bank, descended nose-down, crashed, and was consumed by fire.

Examination Findings

Examination of the wreckage revealed indications that both engines were operating at high rpm. A teardown of the engines found that a right engine fuel control bearing had failed. This failure would have allowed improper movement of the fuel control drive shaft. The aircraft's last inspection occurred on November 25, 1992, and at the time of the accident, the aircraft was 13 hours overdue for a required 150-hour inspection. Additionally, a service bulletin addressing maintenance of the fuel control bearings had not been complied with. The owner/pilot had not completed formal ground school instruction regarding the airplane's systems and operation.

Occupants and Configuration

The aircraft had nine seats, but ten occupants were aboard at the time of the accident.

Probable cause

The pilot's improper remedial action concerning a right engine power anomaly, and his failure to maintain adequate airspeed during go-around from an aborted precautionary landing, which resulted in a loss of aircraft control and an uncontrolled descent. Factors related to the accident were: failure of the owner/operator/pilot to assure proper maintenance inspection of the aircraft, failure to comply with a service bulletin concerning the engine fuel controls, subsequent bearing failure in the right engine fuel control, and the pilot's lack of familiarity with this make and model of aircraft.
