The commercial pilot was accompanied by another crew member on an aerial surveying flight from Wonderboom to the Ulundi area in Kwa Zulu Natal. After completing the survey flight, the aircraft landed at Richards Bay in order to re-fuel for the return flight to Wonderboom. Cockpit indications were normal and the gear indication lights showed a positive gear down indication on all three gears. On touch down, however, the left wing started to drop and the gear warning horn sounded as the left-hand main gear collapsed. The pilot immediately initiated a go-around and retracted the gear. After the gear was retracted, the 'gear in-transit'? warning light extinguished but the left-hand main gear indication remained down and locked. The pilot stated that the airspeed indication and absence of asymmetric drag suggested, however, that the left-hand gear had indeed retracted. He declared an emergency and flew back to Wonderboom instead of landing at Richards Bay as was initially planned. On arrival at Wonderboom, the pilot again selected the gear down, whereupon he obtained three greens although the 'gear in-transit'? warning light remained illuminated throughout. Prior to landing on Runway 29, Wonderboom, he shut down and feathered both engines in anticipation of another left-hand gear collapse. On touch down the left-hand main gear again collapsed as anticipated causing the aircraft to veer to the left off the runway. Damage was limited to the left-hand wing and propeller. No injuries were sustained. PROBABLE CAUSE: All indications are that the left-hand main gear collapsed on landing as a result of the side braces not being driven into the fully extended over centre position prior to landing. Metallurgical analysis of the failed landing gear components revealed no pre- existing failures or prior defects that could have contributed to the accident and it was concluded that all failures occurred as a result of an overload condition.
