Aircraft involved
Factual narrative
ON A FLT AFTER AN ANNUAL INSPN, THE PLT COULD NOT RETRACT THE GEAR, USING THE NORMAL ELECTRICAL SYS. IT REMAINED EXTENDED WITH THE GREEN SAFE LIGHT ON & THE GEAR POINTER INDICATING DOWN. HE TRIED TO ASSIST THE NORMAL SYS WITH THE MANUAL HANDCRANK, ALTHOUGH THE PLT HANDBOOK DID NOT ALLOW THIS PRACTICE, BUT TO NO AVAIL. HE THEN USED THE HANDCRANK TO MOVE THE GEAR TO THE EXTENDED POSITION, BUT THE GREEN LIGHT WOULD NOT REILLUMINATE. THE PLT ELECTED TO LAND ON THE DIRT OVERRUN AREA, BUT DID NOT SEE A GRADED DIRT BANK, SHORT OF THE OVERRUN. THE GEAR HIT THE BANK & COLLAPSED DURING THE LANDING. THE LANDING GEAR CIRCUIT BREAKER WAS FOUND IN THE 'POPPED' POSITION. THE NORMAL & EMERGENCY GEAR SYS HAD BEEN CHECKED DURING THE ANNUAL INSPECTION. THE MECHANIC SAID THAT ALL BREAKERS WERE IN ON THE DAY BEFORE THE FLT. REPORTEDLY, THE PLT WAS UNAWARE OF A CHECKLIST ITEM TO ASSURE ALL BREAKERS WERE IN BEFORE STARTING THE ENG. THE INVESTIGATION DID NOT REVEAL WHEN OR WHY THE LANDING GEAR CIRCUIT BREAKER GOT INTO THE POPPED POSITION. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
