The pilot took off with the intention of doing a local flight. However, he could not locate any lift so he returned for a circuit. While on very short finals the aircraft encountered undershoot windshear. The right wing struck a small bush some 5 to 10 metres short of the threshold. The wing was further damaged in the subsequent contact with the ground. The particular bush has since been removed.
