NTSB narrative
DURING AN ATTEMPT TO LAND WITH A 15-20 KNOT RIGHT CROSSWIND, THE PILOT 'PUSHED LEFT RUDDER JUST BEFORE TOUCHDOWN' BUT STATED THAT HE MUST HAVE PUSHED TOO HARD, BECAUSE THE AIRCRAFT TOUCHED DOWN 'AT A SLIGHT ANGLE TO THE LEFT.' THE PILOT ABORTED THE LANDING WHEN THE AIRCRAFT STARTED TO ANGLE OFF THE LEFT SIDE OF THE RUNWAY. SHORTLY AFTER THE AIRCRAFT BECAME AIRBORNE, AT AN ALTITUDE OF APPROXIMATELY 4 FEET AGL, THE LEFT WING STRUCK A WIND SOCK POLE AND SEPARATED FROM THE REST OF THE AIRCRAFT.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL WHILE ATTEMPTING TO LAND IN CROSSWIND CONDITIONS. DURING THE ENSUING ABORTED LANDING, THE PILOT FAILED TO ENSURE ADEQUATE OBSTACLE CLEARANCE AND THE AIRCRAFT'S LEFT WING STRUCK THE WIND SOCK POLE.

- 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.
