NTSB narrative
THE PLT REPORTED THAT HE NOTED A FAIRLY LOUD SOUND AS THE LANDING GEAR LOCKED IN THE UP POSITION. LATER, HE WAS UNABLE TO EXTEND THE GEAR WITH EITHER THE NORMAL OR EMERGENCY SYSTEMS. THE CIRCUIT BREAKER WOULD POP EACH TIME HE TRIED THE NORMAL SYSTEM. THE EMERGENCY GEAR HANDCRANK WOULD NOT ENGAGE TO EXTEND THE GEAR MANUALLY. THE ACFT WAS LANDED WITH THE GEAR RETRACTED. AN INVESTIGATION REVEALED THAT A BUSHING, PN 35-810077-3, IN THE LANDING GEAR ACTUATOR HAD FAILED. THIS ALLOWED A WORM GEAR IN THE ACTUATOR TO MOVE AND JAM THE REDUCTION GEAR. THIS ALSO PREVENTED THE HANDCRANK FROM ENGAGING.

- 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 1983-03-16.
