Probable cause & findings

PILOT'S IMPROPER USE OF THE LANDING GEAR MECHANISM DURING THE LANDING ROLL, WHICH RESULTED IN THE PARTIAL COLLAPSE OF THE LANDING GEAR.

Factual narrative

THE PILOT STATED THAT HE HAD EXTENDED THE LANDING GEAR AND FLAPS DURING THE DOWNWIND LEG OF THE TRAFFIC PATTERN; HIS PASSENGER AND A GROUND WITNESS CONFIRMED THAT THE GEAR WAS EXTENDED DURING THE FINAL APPROACH AND TOUCHDOWN PHASE OF FLIGHT. THE PILOT REPORTED THAT HE VISUALLY VERIFIED THAT THE GEAR WAS DOWN AND LOCKED PRIOR TO TOUCHDOWN, BUT SHORTLY AFTER TOUCHDOWN THE LEFT WING STARTED LOWERING AS THE LEFT MAIN AND NOSE GEAR COLLAPSED. POST-ACCIDENT EXAMINATION OF THE LANDING GEAR SYSTEM REVEALED NO EVIDENCE OF PRE-IMPACT MALFUNCTION; THE FAA INSPECTOR REPORTED THAT THE 'ENTIRE LANDING GEAR SYSTEM WAS IN A TRANSIT MODE....DURING THE LANDING ROLL....' THE PILOT STATED THAT HE MIGHT HAVE INADVERTENTLY RETRACTED THE LANDING GEAR, BUT HE DID NOT REMEMBER. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
