Incident Overview
A certified flight instructor (CFI) was instructing his recently soloed primary student in crosswind takeoff and landing techniques. To expose the student to crosswind conditions, the CFI selected a runway that provided a near 90-degree left crosswind of 8 knots.
Sequence of Events
The aircraft touched down on the runway centerline. Immediately thereafter, it began to drift to the right. The CFI took control from the student and applied left aileron and left rudder inputs to return to the centerline. Despite using full flight control inputs, the aircraft continued skidding to the right. Seconds later, directional control was lost, and the aircraft initiated a rapid left turn toward the left side of the runway. The CFI attempted to redirect the aircraft back to the right but described the effort as "too little, too late." Consequently, the aircraft collided with a sign.
Aftermath
Following the collision, the CFI continued the touch-and-go landing and took off. While airborne, he evaluated the damage to the aircraft. He then landed into the wind using runway 12. As the aircraft decelerated, it veered off the runway and impacted another sign.
