Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped amphibious airplane reported that, during the landing roll, the airplane veered to the left. The pilot added full right rudder, but the airplane exited the left side of the runway and impacted a ditch. The right main landing gear sheared off and the right wing struck the ground. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located about 12 miles east of the airport reported that, about 34 minutes before the accident, the wind was from 090° at 11 knots, gusting 15 knots. The same automated station reported that, about 26 minutes after the accident, the wind was from 080° at 7 knots, gusting to 16 knots. The airplane landed on runway 18.
