Aérospatiale / Eurocopter AS332 SuperPuma

The Eurocopter AS332 Super Puma is a four-bladed, twin-engine, medium-size utility helicopter marketed for both civil and military use. Originally designed and built by Aérospatiale, it is an enlarged and re-engined version of the original Aérospatiale Puma. The Super Puma first flew on 13 September 1978.

Design and development

The type has proved immensely successful, chosen by 37 military forces around the world, and some 1,000 civil operators. The Super Puma has proved especially well-suited to the North Sea oil industry, where it is used to ferry personnel and equipment to and from oil platforms. In civilian configuration it can seat approximately 18 passengers and two crew, though since the early 2000s most oil companies have banned use of the middle-rear seat reducing effective capacity to 17+2. This down-rating is due to difficulties encountered in evacuating through the rear-most windows in crashes at sea.

A wide variety of specialised military variants are in use, including dedicated Search and rescue and ASW versions. Since 1990, military Super Pumas have been marketed as the AS532 Cougar.
