## Other investigations on N9307P (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: THE PILOT'S INADEQUATE COMPENSATION FOR WIND CONDITION AND FAILURE TO MAINTAIN RUNWAY ALIGNMENT DURING THE LANDING ROLL. A CONTRIBUTING FACTOR WAS A SHIFTING CROSSWIND.
