On January 7, 1989, a Beechcraft 90 King Air (registration N784K) operated by Malcolm Jacobs Aviation was involved in an aviation accident near Paducah, United States of America during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: Pilot failed to maintain proper altitude while maneuvering to land. Probable contributing factors were inoperative weather radar, thunderstorms, lightning, an undetermined electrical problem, dark night, the pilot's improperly planned approach and visual… This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A pilot diverting due to thunderstorms experienced engine anomalies, saw a white arc, then lost sight of the airport during a 360° turn and crashed into trees after misidentifying a strobe light.

Flight Encounter

During a nighttime return flight to Decatur, Alabama, the pilot noted that the weather radar was inoperative. Despite forecasted thunderstorms, the pilot visually avoided them. While maneuvering around the storms, the pilot observed a reduction in engine power, a slight yaw, indications of fuel flow irregularity, and that both left and right boost pumps were inoperative. Around the same time, the pilot reported seeing a white arc that appeared to jump from the prop, spinner, or nacelle area to the aircraft's nose.

Diversion and Approach

Due to the weather conditions, the pilot elected to divert to Paducah. After the airport was in sight, the pilot needed to lose altitude before landing and was cleared to make a 360° turn. During the turn, the pilot lost sight of the airport, then rolled out on the wrong heading and began flying toward a strobe light at an industrial complex. When the pilot realized the error and saw the airport, he turned toward the runway. While maneuvering, the aircraft lost altitude, struck trees, and crashed.

Examination

An examination of the engines and fuel pumps revealed no indication of a preimpact failure. No physical evidence of a lightning strike was found, but the nose and engines were badly damaged from the impact.

Probable cause

Pilot failed to maintain proper altitude while maneuvering to land. Probable contributing factors were inoperative weather radar, thunderstorms, lightning, an undetermined electrical problem, dark night, the pilot's improperly planned approach and visual perception, and the trees.
