2 December 1978, when the pilot of XW614, 659 Sqn, became disorientated during a sortie and crashed into Lough Ross, killing the two crew. XW614 was the last of five Scouts written off during operations in the province. Exports Unlike its naval counterpart, the Scout did not achieve the same export success as the Wasp, with the Royal Jordanian Air Force acquiring three helicopters, two were operated in Uganda, and Bahrain had two helicopters, which were operated by the Bahrain Public Security Force in police service roles. The Scout never received civilian airworthiness certification, which prevented it from being sold to civilian operators, and meant that the design was used exclusively by the army from the outset. All current operators require an 'Experimental' certificate to fly them. Two Scout helicopters were acquired by the Royal Australian Navy (RAN) in April 1963 and were operated by 723 Naval Air Squadron, with the aircraft being rotated aboard the hydrographic survey ship HMAS Moresby. The RAN Scouts proved the practicalities of operating helicopters from small ships for the RAN, and the RAN operated these helicopters up until 1973, when they were replaced by Bell 206B-1 Kiowas. The RAN experience with the Scouts aboard HMAS Moresby illustrated the need for a higher-level maintenance regime as a result of operating the helicopters in areas with high concentrations of abrasive coral sand encountered around the Australian coastline and the detrimental effect that it had on the rotor blades, airframe and engine components. Despite the additional effort to maintain the helicopters, the Scouts were considered to be superior to the seaplanes and flying boats that had previously been used in this role. One of the Scouts ditched in Wewak Harbour while taking off from HMAS Moresby in April 1967; it was subsequently recovered but the aircraft was deemed to be written off. Survivors Although none are operational in military roles, there are still Scouts in the air; mainly in the UK; as of 2014 there were 10 Scouts remaining on the UK civil register, including the Army Air Corp's Historic Flight's aircraft. Outside the UK, the last of six Scouts that were exported to New Zealand have been withdrawn from use, leaving only ZS-HAS flying in South Africa operating.
