Agusta A109E, G-TYCN
At approximately 100 ft agl during an approach to land, the pilot noticed an increased rate of descent, which he tried to arrest by raising the collective control and the aircraft nose. This had little effect and the aircraft landed heavily despite the application of maximum torque just before touchdown. The aircraft bounced into the air and swung through approximately 250° before coming to rest. It is likely that the aircraft entered a votex ring state from which it was unable to recover in the height available.
