The AgustaWestland AW139 is a 15-seat medium sized twin-engined helicopter manufactured by AgustaWestland. Originally designed and developed jointly by Agusta and Bell Helicopters and marketed as the Agusta-Bell AB139, it was redesignated the AW139 when Bell withdrew from the project.
The AW139 has become one of AgustaWestland's most influential products; it has been subsequently developed into two enlarged medium-lift helicopters, the military-orientated AW149 and the AW189 for the civil market.
In 1997, the Italian helicopter manufacturer Agusta launched a programme to develop a replacement for the Bell Huey family of helicopters (which had been built in very large numbers by Bell Helicopter and under license by Agusta) with a potential market of 900 aircraft being predicted. In 1998, Bell and Agusta entered into an agreement, setting up a joint venture, Bell/Agusta Aerospace Company (BAAC) to develop two aircraft: a conventional helicopter and a tiltrotor aircraft. These became the Bell/Agusta AB139 and Bell/Agusta BA609 respectively; Bell was to be the leading partner for the development of the BA609 while Agusta would be the lead partner in AB139; it was intended for production, sales, and support to be shared.
On 26 September 2000, the first order for the type was placed by Bristow Helicopters. The first AW139 flew on 3 February 2001 at Vergiate in Italy; the first production aircraft made its first flight on 24 June 2002. European JAA certification was received in June 2003, and its FAA type certificate followed in December 2004. By May 2005, the AW139 had received in excess of 100 orders worldwide.
The AW139 was evaluated as a contender in the U.S. Army's Light Utility Helicopter Program, the rival Eurocopter EC145 was selected instead. At the Farnborough Air Show in 2006, AgustaWestland announced the AW149 as a multi-role battlefield helicopter variant of the AW139. Around 720 AW139s have been sold in almost 60 countries to over 200 customers so far for many roles including VIP/corporate transport, passenger transport, law enforcement, fire fighting, offshore transport, search and rescue, emergency medical service, disaster relief and maritime patrol.
In late 2006, it was announced that the Japan Coast Guard had selected the AW139 as the replacement for its fleet of Bell 212 helicopters; 24 AW139s are expected to be delivered, beginning in 2008. The Irish Air Corps began taking delivery of its first AW139s in 2006. The replaced the Aerospatiale Alouette III in the army support and basic transport roles. In 2007, a second production line at the AgustaWestland Aerospace plant in Philadelphia, United States was established. By 2011, AgustaWestland was producing 90 AW139s a year, the helicopter had also directly produced 9.5% of the company's overall revenue in 2010.
The AW139 is a conventional twin-engine multi-role helicopter. It has a five-bladed fully articulated main rotor with a titanium hub and composite blades and a four-bladed articulated tail rotor. It is fitted with a retractable tricycle landing gear, the two aft wheels retract into external sponsons, which are also used to house emergency equipment. It is flown by a crew of two pilots, with up to 15 passengers accommodated in three rows of five. The AW139 had been aimed at a vacant niche in the market, sitting below larger types such as the Eurocopter AS332 Super Puma and Sikorsky S-92 and above smaller ones like the Bell 412 and Eurocopter EC155. It is powered by two FADEC-controlled Pratt & Whitney Canada PT6C turboshaft engines; the FADEC system seamlessly adjusts the engines for pilot continence and passenger comfort, and can automatically handle events such as a single-engine failure without noticeable deviation.
The AW139 has a modular glass cockpit, which has been designed for single-pilot flight operations while under instrument flight rules conditions; it has also been designed for compatibility with night vision goggles. The AW139 can also have a four-axis autopilot installed, which allows for functions such as an auto-hover capability. A range of specialist equipment can be configured per customer demand, these options include an auxiliary fuel tank, rescue hoists, cargo hooks, search and weather radar, ice protection systems, external cameras and search lights, and specified seating arrangements. Rotor & Wing has described the AW139's flying attitude as 'docile and predictable'.
