NTSB narrative
DRG A RTRN FLT AT NGT TO DECATUR, AL, THE PLT NOTED HIS WX RADAR WAS INOP. HE VISUALLY AVOIDED THUNDERSTORMS (TSTMS), WHICH HAD BEEN FORECASTED. WHILE AVOIDING TSTMS, HE NOTED A REDUCTION IN ENG POWER, A SLIGHT YAW, INDCNS OF FUEL FLOW IRREGULARITY & THAT THE LEFT & RGT BOOST PUMPS WERE INOP. THESE OCCURRED AT ABOUT THE TIME, HE SAW A WHITE ARC WHICH HE SAID HAD JUMPED FROM THE PROP, SPINNER OR NACELLE AREA TO THE ACFT'S NOSE. DUE TO THE WX, HE ELECTED TO DIVERT TO PADUCAH. AFTER THE ARPT WAS IN SIGHT, HE NEEDED TO LOSE ALT BEFORE LANDING & WAS CLEARED TO MAKE A 360 DEG TURN. WHILE TURNING, HE LOST SIGHT OF THE ARPT, THEN ROLLED OUT ON THE WRONG HEADING & STARTED FLYING TOWARD A STROBE LIGHT AT AN INDUSTRIAL COMPLEX. WHEN HE REALIZED HIS ERROR & SAW THE ARPT, HE TURNED TOWARD THE RWY; BUT AS HE WAS MANEUVERING, THE ACFT LOST ALT, HIT TREES & CRASHED. AN EXAM OF THE ENGS & FUEL PUMPS REVEALED NO INDCN OF A PREIMPACT FAILURE. NO PHYSICAL EVIDENCE OF A LIGHTNING STRIKE WAS FOUND, BUT THE NOSE & ENGS WERE BADLY DAMAGED FROM 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.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1989-01-08.
