Bantam B22 microlight aircraft ZK-JAS underwent an uncontrolled descent and collision with the ground near the Rotorua Microlight Club airstrip at Mead Road, near Rotorua, on 12 December 1993. Safety issues included the hazard of reduced performance due to excess load, high density altitude, and sink encountered after take-off, and potential for stall onset during a turn at low airspeed.
