What happened
On 22 July 2016, a Zenair CH 601UL Zodiac, registration G-CBUR, was performing a private flight from Headon Microlight Strip near Gamston, Nottinghamshire. The pilot elected to use Runway 14 for the departure, intending to utilize the downslope to mitigate the effects of a potential 3 kt tailwind. At the time of the accident, the ambient temperature was 26ºC, and the aircraft was operating near its maximum takeoff weight.
The takeoff roll exceeded the pilot's expectations. As the aircraft approached a dip in the grass runway, the pilot initiated rotation, though later noted the airspeed was likely lower than usual. Shortly after lifting off, the controls became heavy and the left wing dropped. The aircraft subsequently veered into a hedge and spun on its left wingtip. There were no injuries to the pilot or the single passenger, though the aircraft sustained damage beyond economic repair.
The investigation
The investigation examined the takeoff performance and environmental conditions at the time of the incident. The AAIB established that the pilot did not perform a formal calculation of the required takeoff distance, relying instead on familiarity with the airstrip. The investigation also reviewed the aircraft's weight and balance, noting it was near its maximum allowable limit during the departure.
