"The A119 Koala single-turbine light helicopter has the capacity to transport seven passengers plus the pilot."
The helicopter design work was carried out at Agusta's Cascina Costa di Samarate engineering centre. Agusta continues full-scale production, marketing and support of the Koala. Denel is marketing the helicopter in South Africa and has set up an assembly production line and a spares and components manufacturing facility to support the main production line in Cascina Costa. AgustaWestland has expanded the facility of its US subsidiary, Agusta Aerospace Corp in Philadelphia, for the manufacturing and assembly of the A119. The first US manufactured Koala made its maiden flight in June 2005. MULTI-ROLE HELICOPTER The A119 Koala single turbine light helicopter has the capacity to transport seven passengers plus the pilot or slung loads up to 1,000kg. The maximum cruise speed is over 260km/h (140kt) and the maximum range with seven passengers and their luggage is more than 650km (350nm). The helicopter can be equipped for search and rescue, medical evacuation, surveillance and passenger and light cargo transport roles. For firefighting, the Koala can be fitted with the Simplex 323 Fire Attack System, which has a 1,200l capacity. The Koala is in service in Australia, Austria, Brazil, Italy, Turkey, UK, USA and Venezuela. Over 130 orders have been received including: Tex-Air of Texas, USA (transport for the offshore oil and gas industry), Elieuro of Italy (firefighting), New York Police Department, Pennsylvania State Police, Mississipi air ambulance, LinFox of Australia, J.B.

The AW119 Ke has an increased maximum take-off weight of 2,850kg and new main rotor blades with a higher rotation rate for additional lift and temperature operating range. Fumigacion Aerea Andaluza (FAASA) of Spain is the launch customer for the new helicopter, with an order for six placed in March 2007, for firefighting. The AW119 Ke can be fitted with the Simplex Model 323 Fire Attack System, with a water capacity of 1,200l. The AW119 Ke received European certification in June 2007. US certification is expected in 2008. AW119 Ke production is being carried out in the USA, at AgustaWestland's Philadelphia plant. KOALA DESIGNThe fuselage is made of high-strength aluminium alloy structure. The composite main rotor has a titanium hub with composite grips and elastomeric bearings. The four blades, of diameter 10.83m, are fully articulated. The tail rotor is two-bladed. A119 COCKPIT FEATURESThe A119 features dual controls and a three-axis autopilot.
