NTSB narrative
THE PILOT REPORTED THAT THE AIRCRAFT LANDED NORMALLY AND DURING THE LANDING ROLL A LOUD 'BANG' WAS HEARD AND THE RIGHT MAIN LANDING GEAR COLLAPSED. AN INVESTIGATION WAS CONDUCTED BY AN FAA AIRWORTHINESS INSPECTOR. DURING THIS INVESTIGATION, IT WAS NOTED THAT A WASHER IN THE RIGHT MAIN LANDING GEAR ASSEMBLY FAILED. SUBSEQUENT INVESTIGATION, INCLUDING A REVIEW OF THE AIRCRAFT MAINTENANCE RECORDS, REVEALED THAT CESSNA AIRCRAFT SERVICE INFORMATION LETTER NUMBER ME83-37, DATED NOVEMBER 23, 1983 HAD NOT BEEN COMPLIED WITH. THIS SERVICE LETTER RECOMMENDED REPLACEMENT OF THE ORIGINAL WASHERS WITH A NEW WASHER, CESSNA PART NUMBER S1450-5H12-063. (OLD PART NUMBER 5045018-2)
Probable cause
RIGHT MAIN GEAR SCISSORS ASSEMLBY BECOMING DISCONNECTED DURING LANDING ROLL, ALLOWING THE RIGHT RUN LANDING GEAR TO COLLAPSE; SCISSOR ASSEMBLY WASHERS NOT BEING REPLACED AS RECOMMENDED IN CESSNA AIRCRAFT SERVICE BULLETIN ME83-37..

- 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.
