NTSB narrative
THE AIRPLANE ENTERED THE TRAFFIC PATTERN FOR A LANDING ON RUNWAY 29, BUT THE PILOT WAS THEN ASKED BY THE TOWER CONTROLLER TO LAND ON RUNWAY 16. THE PILOT STATED THAT THE 'APPROACH AND LANDING WERE NORMAL' BUT 'THE WIND GUSTED AND BALLOONED US A FEW FEET.' AFTER TOUCHING DOWN ON THE RUNWAY AGAIN, THE LEFT MAIN LANDING GEAR COLLAPSED AND THE AIRPLANE VEERED OFF TO THE RIGHT SIDE OF THE RUNWAY. A WITNESS REPORTED THE LANDING GEAR WAS DOWN PRIOR TO THE BOUNCE, BUT THEN OBSERVED THE LEFT GEAR 'IN TRAIL' AFTER THE BOUNCE. THE LANDING GEAR WAS FUNCTIONALLY TESTED AND NO MECHANICAL MALFUNCTIONS WERE FOUND.
Probable cause
THE COLLAPSE OF THE LEFT MAIN LANDING GEAR FOR AN UNDETERMINED REASON.

Source notes (4)
- 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.
