The Gulfstream American GA-7 Cougar is an American all-metal, 4-seat, twin-engined light aircraft. The Cougar was a twin-engine development of the Gulfstream American AA-5B Tiger and traces its lineage to the AA-1 Yankee Clipper and the Bede BD-1.

Development

As a development of the company's single-engined designs, Grumman American developed a twin-engined version, designated the GA-7 which it named the Cougar, in keeping with the existing Lynx, Cheetah and Tiger names for aircraft in the company's line. The prototype Cougar with two {{convert|160|hp|kW|0|abbr=on}} Lycoming O-320 engines first flew on the 29 December 1974. The prototype had a sliding canopy but this was soon changed to a starboard side door on the production aircraft. With other rework required the production prototype did not fly until 14 January 1977.[2]

Before production started the company was taken over on 1 September 1978 by American Jet Industries, who changed the company name to Gulfstream American.[1] Production of the Cougar ran for only two model years, 1978 and 1979, before production was halted. Just 115 Cougars were delivered.[4][3]

In 1995 the type certificate for the GA-7 was sold to SOCATA of France who intended to produce the aircraft as the TB 320 Tangara for the training market.[4] It was also to develop a variant with two Lycoming O-360-A1G6 engines of {{convert|180|hp|kW|0|abbr=on}} each and a re-designed cockpit, it was designated the TB 360. The first Tangara was a modified Cougar, had {{convert|160|hp|kW|0|abbr=on}} engines and first flew in mid-1996. The complete Tangara prototype was also a converted Cougar and had the {{convert|180|hp|kW|0|abbr=on}} engines. It first flew in February 1997. After delays in getting the type certified SOCATA announced at the end of 1999 that it had delayed indefinitely plans to certify the type.[5]

Design

The Cougar is a twin-engined low-wing cantilever monoplane using a honeycomb and bonded metal construction that is the hallmark of the line since the BD-1. The prototype's single spar wing was upgraded to a double-spar configuration and this allowed a wet wing.

The Cougar is powered by a pair of wing-mounted Lycoming O-320-D1D engines of {{convert|160|hp|kW|0|abbr=on}}. It carries four people at maximum cruise speed of {{convert|160|kn|km/h|0|abbr=on}} and a typical cruise speed of {{convert|140|kn|km/h|0|abbr=on}}. It was certified under US FAR Part 23 on 22 September 1977.[6]

Variants
