AgustaWestland AW189

The AgustaWestland AW189 is a twin-engined, super-medium-lift helicopter manufactured by Leonardo S.p.A. It is derived from the AW149, and shares similarities with the AW139 and AW169.

On 20 June 2011, development of the eight-tonne twin-engine AW189 was formally announced by AgustaWestland at the Paris International Air Show; at the time, the company planned to have the new rotorcraft certified by 2013 and in service in 2014. The AW189 is a civil-orientated version of the military AW149, which in turn is an enlarged development of the AW139; in 2011, AgustaWestland CEO Bruno Spagnolini stated that: "The AW139 and the AW189 are two very different aircraft but they both share the same general concept in architecture". AgustaWestland stated it aimed to sell the AW189 for offshore helicopter support, search and rescue (SAR), and passenger transport roles.

On 21 December 2011, the first AW189 conducted its maiden flight from AgustaWestland's facility in Cascina Costa, Italy. During the flight test program, six AW189s were used; these were four prototypes and a pair of pre-production aircraft. The pre-production aircraft were used to develop mission kits and configurations for offshore and SAR roles, enabling these to be immediately certified and available for customer selection. In August 2013, the fifth prototype was dispatched to the UK, so that AgustaWestland's UK branch could begin work on certifying the type for SAR operations. In June 2013, AgustaWestland announced that the AW189 had entered full-scale production.

In October 2013, the first production model performed its first flight; at the same time, work was proceeding on setting up a second production line for the type at AgustaWestland's center in Yeovil, United Kingdom. In February 2014, the AW189 received type certification from the European Aviation Safety Agency (EASA); the Federal Aviation Administration (FAA) issued its certification for the type in March 2015. In August 2015, civil certification for the AW189 was issued by the Interstate Aviation Committee (IAC).

In June 2015, it was reported that slow development of the ice-protection systems that to be offered upon the AW189 had delayed the introduction of Bristow Helicopters UK-based SAR operations using the type, at the time being in a state of "operational evaluation". In September 2015, AgustaWestland announced that EASA certification of the AW189's limited ice protection system had been granted, and stated that the rotorcraft was the first in its category to receive such certification. In autumn 2015, AgustaWestland conducted icing trials in Alaska to provide flight within full icing conditions certification as part of efforts to qualify the type for the SAR role; validation of the full-ice protection system was scheduled for mid-2016.

In October 2017, Leonardo announced the development of the AW189K variant, powered by two 2500 hp Aneto-1K turboshafts produced by Safran Helicopter Engines. EASA certification for the AW189K was initially expected in late 2018 this was eventually achieved in June 2020; hot and high operations would benefit from the additional 500shp (370 kW) per engine and the Aneto's specific fuel consumption was planned to be 10% lower than the replaced CT7s. Gulf Helicopters was the launch customer of the AW189K.

The AW189 is a medium-sized twin-engined helicopter with a five-bladed fully articulated main rotor, a four-bladed tail rotor and a retractable tricycle landing gear. It is powered by two General Electric CT7-2E1 turboshaft engines. AgustaWestland refer to the AW189 as being a "super-medium class" helicopter, emphasizing its suitability for long-range operations. During development, the AW189 was designed to comply with the latest international regulatory safety requirements EASA/FAA Part 29, JAR OPS 3/EU-OPS. Of particular importance to the type's use for offshore operations, such as search and rescue and services to the oil and gas industries, the main gearbox has been designed to provide for a 50-minute run-dry capacity, in excess of requirements and a unique feature to the AW189. Aspects of the AW189 are deliberately similar to the AW139 and AW169; these helicopters share similar flight performance characteristics, safety features, and design philosophies. Areas of the aircraft's operation, such as maintenance and the layout of the cockpit, also continue this concept, which reportedly makes operations more cost effective.

The cockpit features high levels of external visibility and advanced situational awareness technologies, and is designed to reduce crew workload and enhance safety. Avionics on the AW189 are fully integrated and include four color LCD panels, a four-axis dual-duplex digital automatic flight control system, autopilot, search/weather radar, cockpit voice recorder, flight data recorder, night vision goggle-compatibility, health and usage monitoring system, moving map system, SATCOM, synthetic vision system, emergency locator system, helicopter terrain avoidance system (HTAWS), traffic collision avoidance system II (TCAS II), direction finder, forward looking infrared (FLIR) camera, and VHF/UHF radio. The avionics were designed to use an open architecture, making customer-specified upgrades and additions easier and enabling additional options.
