Narrative:
The de Havilland DHC-1 Chipmunk 22 G-BBNA was substantially damaged when it ran off the runway after landing at Husbands Bosworth Airfield, Leicestershire after a glider towing sortie.

The aircraft had completed its 6th aerotow of the day and was recovering to land on the former taxiway parallel to grass runway 09. The surface wind was estimated to be 040/5-10 kts. All the previous 5 landings had been unremarkable, and the aircraft had remained straight on the asphalt surface and slowed normally. Shortly after a normal 3 point landing the aircraft veered to the left and departed from the former taxiway. The pilot initially applied rudder to correct the swing and when he felt that this has insufficient effect applied a large amount of power. This action reduced the angle of departure from the landing strip but sensing that he was close to a substantial hedge the pilot returned the throttle to idle. Shortly afterwards the left wingtip contacted the hedge violently turning the aircraft into the hedge and stopping it against a large tree embedded therein. The pilot was able to exit the wreckage unassisted and received minor injuries namely a small cut and bruising to his left hand. The aircraft was damaged beyond economic repair in the accident.
