The airplane veered left until impacting nearby trees seconds after taking off from an airstrip. The pilot had previously departed from the 1,800-foot-long private airstrip, but this was his first departure from the airstrip in the Cessna A185F, which has a 300-horsepower engine. No anomalies were detected with the airplane during the pilot's preflight inspection. The pilot indicated that during the initial climb in the calm wind, he had inadequately applied corrective rudder to compensate for the airplane's left turning tendency (also known as torque/P-factor).
