What happened
The pilot was preparing to perform a crosswind takeoff on runway 22, which measures 5,502 feet by 75 feet and is surfaced with asphalt. The intended flight plan included practicing stop-and-go landings on runway 11. During the takeoff roll, the Cessna 180H veered to the left. In an attempt to maintain directional control, the pilot reduced power and applied right rudder; however, the aircraft departed the left side of the runway and nosed over. The pilot estimated the winds during departure were a direct left crosswind of approximately 10 knots.
The investigation
An examination of the aircraft revealed that the left wing spar was broken, the vertical stabilizer had been crushed downward, and the firewall was wrinkled. No other anomalies were identified during the inspection of the airplane.
