## Analysis

The pilot reported that during the landing roll, the airplane “pulled hard right.” He added engine power “to try to get some rudder control” and the airplane veered across the runway to the left. The airplane exited the left side of the runway and impacted airport equipment, which resulted in substantial damage to both wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing runway 29, with wind from 310° at 14 knots, gusting to 21 knots.

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.
