Aviat A-1B Husky, G-GGZZ was substantially damaged on June 6th 2018 in a forced landing, due loss of power on final approach, at Sherlowe Airstrip, Lower Grounds Farm, High Ercall, Shropshire. The official AAIB report into the accident was published on November 8th 2018, and the following is an extract from it...
"The pilot was flying a circuit using short takeoff and landing techniques, with the aircraft’s owner observing from the rear tandem seat. The circuit was flown below 500 ft aal, because of an adjacent military airfield, and on the base leg the pilot selected full flap, before slowing to an indicated speed of 45 mph. He then turned onto the final approach, aiming to touchdown approximately 50 m beyond the downwind end of the runway but, at less than 100 ft aal, the aircraft descended below the desired approach angle.
With the engine running slightly above idle, the pilot advanced the throttle steadily but the engine failed to respond, so the pilot was forced to try and land the aircraft in a field of rapeseed adjacent to the airstrip. The right main landing gear collapsed on ground contact and the aircraft abruptly decelerated to a halt, some 30 m short of the runway, with its right wingtip resting on the ground. The occupants vacated the aircraft without assistance.
Following the accident, the owner reported that he had practised numerous landings over a period of several weeks, because he was preparing to take part in a competition. On a couple of occasions the engine had not responded when, to cushion his touchdown, he rapidly advanced the throttle from idle.
After discussing this with engineers, he concluded that his rapid advancement of the throttle had caused a rich cu and, although the issue did not recur in the three weeks prior to the accident flight, he did brief the pilot about this before they flew. The pilot had, therefore, been careful to avoid a rich cut, by keeping the engine running above idle and by avoiding rapid movement of the throttle.
No evidence of a technical malfunction was found during the post-accident inspection, and the engine was due to be stripped-down and rebuilt during the aircraft’s repair."
Damage sustained to airframe: Per the above AAIB accident report "Damage to right wing, struts, main landing gear, propeller and engine
