Event Details
A pilot reported an incident during the landing roll at an airport. The aircraft was landing on runway 16. According to the pilot, while rolling out after touchdown, the airplane passed over an uneven crest on the runway surface. This caused the airplane to become momentarily airborne.
Sequence of Events
While airborne, the pilot encountered a gust of crosswind. The gust caused the left wing to rise, and the airplane subsequently veered to the right. The aircraft then departed the runway and entered a ground loop. The pilot did not report any mechanical malfunctions or failures that would have prevented normal operation.
Aircraft Damage
The left wing rear spar sustained substantial damage as a result of the ground loop.
Weather Conditions
Around the time of the incident, an automated weather observing system reported wind from 120 degrees true at 7 knots, gusting to 16 knots. This wind condition was consistent with a crosswind for runway 16.
