A pilot who was seriously injured after a terrifying crash into a hangar was unable to control the aircraft's direction, a report has found.

The accident happened at Stoke Airfield in Rochester on July 27 when a Pegasus Quik was destroyed in the crash soon after taking off.

The report published by the Air Accidents Investigation Branch, a department responsible for looking into civil aircraft accidents, found the pilot and his passenger planned to set off for a private, local flight as the weather conditions were good.

But, the report published on Thursday found: "During the takeoff roll, the aircraft accelerated to about 55 mph, at which point the pilot pushed the basebar to rotate the aircraft.

"The aircraft lifted slightly before the left wing dropped and the aircraft rapidly veered left.

"The pilot was unable to control the aircraft’s direction, and it struck one of several hangars that were located along the left edge of the airstrip."

The accident happened at around 9.30am.

The 58-year-old pilot, who has National Private Pilot's Licence and 546 hours of flying experience, sustained serious injuries and was rushed to hospital by ambulance while miraculously, his passenger escaped unharmed.

In the report, it says the pilot believed the accident was "a combination of a reduction in the headwind and a possible early rotation".

In the last 90 days the pilot had undergone 16 hours of flying, while in the last 28 days, he had undergone five.

A Pegasus Quik is a British-designed ultralight trike with just two seats.
