The AgustaWestland AW109, originally the Agusta A109, is a lightweight, twin-engine, eight-seat multi-purpose
Development of the A109 commenced during the late 1960s as an indigenous rotorcraft suited to commercial operations. A twin-engine arrangement was pursued in response to market interest, while work on the civil model was prioritised over the military-orientated A109B project. On 4 August 1971, the first of three prototypes made its
Following the merger of Agusta and the British company Westland Helicopters to form AgustaWestland, the A109 has been rebranded as the AW109. International involvement in the programme has also been pursued; the company has established final assembly lines at sites in both Italy and the US. Furthermore, hundreds of AW109 fuselages have been manufactured by the Polish aerospace company PZL-Świdnik since the mid-1990s. AgustaWestland formed a joint venture with the Changhe Aircraft Industries Corporation in 2004 that produces and supports the AW109, includes a final assembly line, in China. The AW109 has been in continuous production for 40 years. The AgustaWestland AW119 is a derivative of the AW109, the principal difference being that it is powered by a single engine and has a fixed undercarriage.
Development
Origins
Work on what would become the AW109 commenced during the late 1960s at the Italian helicopter manufacturer Agusta, which sought to design an indigenous rotorcraft suitable for commercial activities. Known as the A109, early designs were of a single-engine helicopter.[3] However, the design team came to recognise that the market found a twin-engine rotorcraft to be more attractive, thus the project was reoriented to fulfil this in 1969, opting to outfit it with a pair of Allison 250-C14 turboshaft engines. While early considerations had been made for a militarised model, which the company internally referred to as the A109B, Agusta intentionally placed a low priority on the work for this variant in favour of other market sectors. In particular, design efforts were concentrated on the eight-seat A109C model.[4]
On 4 August 1971, the first of three prototypes performed the type's maiden flight.[5] The A109 was subject to a protracted flight testing phase, which was largely attributable to the discovery of dynamic instability that took roughly one year to resolve via a modified transmission design.[6] Almost four years later, the first production helicopter was officially completed during April 1975. On 1 June 1975, the type received certification for visual flight rules (VFR) from the Federal Aviation Administration (FAA), permitting the A109 to be operated in North America.[3]
During 1976, deliveries of production A109s commenced to civil customers. The type offered several advantages over the then-
Further development
Shortly following after the launch of the initial production model, Agusta begun work on additional models, primarily for the civil sector. During 1981, an A109A Mk2, that featured a widened cabin, was made available to operators.[8] In 1993, the A109 K2 model was introduced, which was powered by alternative engine in the form of the Turbomeca Arriel 1K1. During 1996, the A109 Power was launched, which was broadly similar to the K2 except for the adoption of yet another powerplant, the Pratt & Whitney Canada PW206 engine.[3] By 2008, according to AgustaWestland, the A109 Power was being operated across 46 countries. In 2006, an enlarged variant, the A109S Grand, was introduced.[3]
The A109 was renamed the AW109 as a consequence of the July 2000 merger of
In February 2014, AgustaWestland announced the development of the AW109 Trekker, an updated model. It is equipped with skid landing gear (being the first twin-engine helicopter produced by the company to have this feature) and is powered by a pair of FADEC-equipped Pratt & Whitney Canada PW207C engines; its avionics are supplied by Genesys Aerospace, which have been designed for single-pilot operations.[11] The Trekker reportedly expands upon the utility capabilities of the standard AW109.[12] Akin to the prior models, the final assembly of the AW109 Trekker is undertaken at sites in both the US and Italy.[3][13]
Design
The AW109 is a lightweight twin-engine helicopter, known for its speed, elegant appearance and ease of control.
A range of
According to AgustaWestland, the AW109 Power features various advanced avionics systems, these include a three-axis autopilot, an auto-coupled Instrument Landing System, integrated
Some models of the AW109 feature the "quick convertible interior", a cabin configuration designed to be flexibly re-configured to allow the rotorcraft to be quickly adapted for different roles, such as the installation or removal of mission consoles or medical stretchers. Mission-specific equipment can also be installed in the externally accessible separate baggage compartment, which can be optionally expanded. Optional cabin equipment includes soundproofing, air conditioning, and bleed air heating.[19] Aftermarket cabin configurations are offered by third parties; Pininfarina and Versace have both offered designer interiors for the AW109, while Aerolite Max Bucher has developed a lightweight emergency medical service interior.[3] The majority of AW109s are fitted with a retractable wheeled tricycle undercarriage, providing greater comfort than skids and taxiing capability.[14][15] For shipboard operations, the wheeled landing gear is reinforced, deck mooring points are fixed across the lower fuselage, and extensive corrosion protection is typically applied.[20]
Optional mission equipment for the AW109 has included dual controls, a
Operational history
Various branches of the Italian military have operated variants of the AW109; the Guardia di Finanza has operated its own variant of the AW109 since the 1980s for border patrol and customs duties, by 2010, it was in the process of replacing its original AW109s with a new-generation of AW109s.[1]
During 1982, the

Between 2007 and 2012, three AW109E Power helicopters were operated under lease by the Royal Australian Navy (RAN) to train naval aircrew.[38]
In May 2008, the Royal New Zealand Air Force (RNZAF) placed an order for five AW109LUH rotorcraft to replace their aging Bell 47 Sioux in a training capacity; they are also used in the utility role to complement the larger NHIndustries NH90 and has seen limited use in VIP missions.[39]
During August 2008, Scott Kasprowicz and Steve Sheik broke the round-the-world speed record using a factory-standard AgustaWestland AW109S Grand, with a time of 11 days, 7 hours and 2 minutes. The AW109S Grand is also recorded as being the fastest helicopter from New York to Los Angeles.[40][41]
