Jan-05-94 Okeechobee, FL. A beech b90 aircraft, crashes killing 10. The pilot (or pilot-rated passenger) reported an "indication" problem & said they intended to land at Okeechobee, but couldn't find the Airport. They then reported engine trouble & said that they would try to land on a road. They circled the area & approached a dirt road with landing lights on.
A car was proceeding on the road in the opposite direction. The plane began to climb, & it entered a left turn. It then rolled into a steep right bank, descended nose down, crashed & was consumed by fire. An exam revealed indications that both engines were operating at high rpm. A teardown revealed a right engine fuel control bearing had failed, which would have allowed improper movement of the fuel control drive shaft.
The plane was last inspected on 11/25/92 & was 13 hrs over a required 150 hr inspection. A service bulletin for maintenance of the fuel Control bearings had not been complied with. The owner/pilot had not completed formal ground school instruction on the airplane systems & operation. The plane had 9 seats; 10 occupants were aboard. 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.
