The AgustaWestland AW109 is a light-weight, twin-engine, eight-seat multi-purpose helicopter built by the Anglo-Italian manufacturer AgustaWestland. Since entering service in 1976 as the Agusta A109, the craft has been used in light transport, medevac, search-and-rescue, and military roles. The AW109 has been in continuous production for 40 years. The AgustaWestland AW119 is a derivative of the AW109 powered only by a single engine instead.

Design and development[edit]

In the late 1960s, Agusta designed the A109 as a single-engine commercial helicopter. It was soon realised that a twin-engine design was needed and it was re-designed in 1969 with two Allison 250-C14 turboshaft engines. A projected military version (the A109B) was considered early on but Agusta initially chose not to pursue development, instead concentrating on the eight-seat A109C version.[1] The first of three prototypes made its maiden flight on 4 August 1971.[2] The flight testing phase of development was prolonged, leading to the first production aircraft being completed almost four years later in April 1975. The delivery of production A109s started in early 1976.

Once released, the aircraft shortly became a commercial success, being often used for roles other than as a light transport; these included the air ambulance and search-and-rescue roles. In 1975, Agusta returned again to the possibility of a military version, thus trials were carried out between 1976 and 1977 using a total of five A109As fitted with Hughes Aircraft TOW missiles. Two military versions emerged from this program, one was intended for light attack/close support missions and the other for shipboard operations.

The Agusta A109 was renamed the AW109 following the July 2000 merger of Finmeccanica S.p.A. and GKN plc's respective helicopter subsidiaries Agusta and Westland Helicopters to form AgustaWestland. For numerous years, fuselages for the AW109 have been manufactured by PZL-Świdnik, which later became a subsidiary company of AgustaWestland in 2010. In June 2006, the 500th fuselage was delivered by PZL-Świdnik, marking 10 years of co-operation on the AW109 between the two companies.[3]

Operational History[edit]

A sale of the Agusta A109 to the Belgian armed forces in 1988 later gave rise to a bribery scandal; it was alleged that Agusta had given the Belgian Socialist Party over 50 million Belgian francs to secure the sale. This scandal led to the resignation and later conviction of NATO Secretary General Willy Claes.

In August 2008, Scott Kasprowicz and Steve Sheik broke the round-the-world speed record using a factory-standard AgustaWestland Grand, with a time of 11 days, 7 hours and 2 minutes. The A109S Grand is also the fastest helicopter from New York to Los Angeles.[4][5]

In July 2013, the South African Air Force reported that 18 AW109s had effectively been grounded due to lack of funding, only occasionally being activated but not conducting flights. The SAAF cited a funding cutback for helicopter operations as the grounding's reason, in 2013, only 71 flight hours were allocated to the whole AW109 fleet. The type may be reduced to flying VIPs rather than being operationally capable; South Africa is also considering selling a number of AW109s, and may cease helicopter operations.[6]
