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 reported that during the landing roll he encountered a crosswind, the left wing lifted, and the airplane began to drift left of the centerline. He attempted to correct with the right rudder and brake but the airplane departed the runway to the left. During the runway excursion, the airplane impacted an airport sign and came to rest on an adjacent runway. The pilot stated that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. Substantial damage was found to the right elevator and firewall. The reported wind at the airport about the time of the accident were from 080 degrees at 11 knots, which created a crosswind component of 2 knots for landing on runway 7.
