Investigator assessment
Analysis narrative
The pilot reported that the airplane’s cockpit temperature was extremely hot during the taxi to the runway. During the takeoff roll, the pilot applied full engine power and the airplane drifted left of the runway centerline. The pilot attempted to correct with a right rudder input, but the airplane continued to go to the left. The airplane struck a runway sign and lights on the left side of the runway, which resulted in substantial damage to the right wing. Postaccident examination of the airplane revealed no preaccident mechanical malfunctions or failures that would have precluded normal operation.
