Aircraft involved

Probable cause & findings

MATERIAL FAILURE OF THE LANDING GEAR RETRACTION AND EXTENSION ASSEMBLY. INADEQUATE MAINTENANCE AND TROUBLESHOOTING PROCEDURES IN COMPANY DIRECTIVES WERE FACTORS IN THIS INCIDENT.

Factual narrative

THE AIRPLANE LANDED WITH THE RIGHT MAIN LANDING GEAR NOT FULLY DOWN AND LOCKED. WHEN THE AIRPLANE TOUCHED DOWN, THE LANDING GEAR WOULD NOT SUPPORT THE WEIGHT OF THE AIRPLANE AND IT COLLAPSED. THE AIRPLANE SUSTAINED MINOR DAMAGE AND NEITHER OF THE TWO CREWMEMBERS ABOARD THE AIRPLANE WERE INJURED. THE LANDING GEAR MALFUNCTION HAD BEEN DISCOVERED WHEN THE LANDING GEAR WOULD NOT CYCLE PROPERLY DURING A MAINTENANCE CHECK FLIGHT. WHEN THE FLIGHT CREW ATTEMPTED TO LOWER THE LANDING GEAR AFTER RETRACTION, THE RIGHT MAIN LANDING GEAR WOULD NOT FULLY EXTEND. ATTEMPTS TO EXTEND THE LANDING GEAR USING EMERGENCY PROCEDURES WERE NOT SUCCESSFUL. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
