FOLLOWING THE PLANE'S DIVERGENCE FROM THE RUNWAY HEADING ON INITIAL ROLLOUT DURING GUSTY WIND CONDITIONS, THE LEFT MAIN LANDING GEAR COLLAPSED. FAA INSPECTION OF THE AIRCRAFT REVEALED THAT THE WELDS TO THE LANDING GEAR LONGERON FITTINGS DID NOT HAVE PROPER PENETRATION. THE PILOT REPORTED THAT THE FITTINGS WERE INSTALLED BY AN FAA REPAIR STATION WHEN THE AIRCRAFT WAS REPAIRED AFTER AN ACCIDENT APPROXIMATELY 300 FLIGHT HOURS PREVIOUS TO THIS OCCURRENCE.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE FAILURE OF THE LEFT MAIN LANDING GEAR ATTACHMENT FITTINGS AS A RESULT OF THE IMPROPER WELDS BY THE MAINTENANCE REPAIR FACILITY. FACTORS IN THE ACCIDENT THAT PRECIPITATED THE GEAR FAILURE WERE THE WIND GUSTS, AND THE PILOT NOT ADEQUATELY COMPENSATING FOR THE WIND CONDITIONS WHICH INDUCED HEAVY SIDE LOADS.
