Loss of engine power
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative

THE AIRPLANE HAD UNDER GONE ROUTINE MAINTENANCE FOR SLOW ACCELERATION ON THE RIGHT ENGINE. MAINTENANCE RECORDS REVEALED THE FUEL CONTROLS WERE CHANGED FROM THE RIGHT ENGINE TO THE LEFT ENGINE. THE AIRPLANE WAS RELEASED BACK TO THE PILOT FOR SERVICE, AND HE DEPARTED FOR HIS HOME STATION. SEVERAL WITNESSES SAW THE AIRPLANE AFTER TAKEOFF AT A LOW ALTITUDE, AND AT A SLOW SPEED. THE AIRPLANE TURNED LEFT, AND THE LEFT WING STRUCK THE GROUND. TWO WITNESSES SAW THE AIRPLANE PASS BY THEM AT A LOW ALTITUDE, AND WROTE, '...AT THIS POINT WE COULD SEE THE LEFT (PORT) ENGINE PROPELLER WAS TURNING VERY SLOWLY. YOU COULD ACTUALLY SEE THE INDIVIDUAL BLADES OF THE PROPELLER TURNING.' A COMPLETE DISASSEMBLY OF BOTH ENGINES, REVEALED NO DISCREPANCIES OTHER THAN IMPACT, AND POST IMPACT FIRE DAMAGE. DISASSEMBLY OF THE LEFT PROPELLER INDICATED THAT THE PROPELLER BLADES WERE AT OR NEAR FEATHER AT IMPACT. THE PILOT HAD A TOTAL OF 106 FLIGHT HOURS IN BEECH A100 AIRCRAFT, ALL IN THE 90 DAYS PRIOR TO THE ACCIDENT, AND 56 HOURS IN THE 30 DAYS PRIOR TO THE ACCIDENT.

Probable cause

the pilot's failure to maintain minimum control speed after an undetermined loss of engine power, which resulted in an inadvertent stall at too low of an altitude to allow recovery.

  • 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: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
