Narrative:
The pilot was conducting touch-and-go landings and had landed uneventfully four times. The fifth touchdown was soft; however, the airplane suddenly turned about 90° to the left. The pilot applied right rudder and reduced the throttle to idle. The airplane departed the runway surface, during which the right horizontal stabilizer struck a light post and sustained substantial damage. The pilot reported that the left brake had locked while braking on rollout. A functional check of the braking system and flight controls did not reveal any mechanical malfunctions or failures that would have precluded normal operation; both left and right wheel brake mechanisms functioned properly. 
Reported wind conditions about the time of the accident were wind from 230° at 7 knots. However, the pilot indicated that he had checked the local weather about 20 minutes before landing, which reported wind from 100° at 3 knots. Therefore, the crosswind component would have been about 130° opposite, and 4 knots increased, from what the pilot had previously received. The pilot likely lost directional control of the airplane during the landing due to the unexpected wind shift.



Probable Cause: The pilot’s loss of directional control during the landing rollout due to the unexpected wind shift, which resulted in a runway excursion.
