Analysis

After completing a successful landing, the pilot of the tailwheel-equipped airplane applied engine power to begin the takeoff. During the takeoff roll, the airplane began to veer right. The pilot applied left rudder to correct; however, the airplane veered left and exited the left side of the runway. The airplane impacted the precision approach path indicators light system resulting in substantial damage to the left wing and left horizontal stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
