Development

Following American Aviation's success with the AA-1 Yankee Clipper two-seat light aircraft in 1969, the company decided to produce a four-seat aircraft. They started with a new "clean-sheet" design that was designated the American Aviation AA-2 Patriot. The AA-2 design did not meet its performance goals during test-flying and only one was ever built. Still needing a four-seat aircraft to fill its product line, the company simply enlarged the external and cabin dimensions of the AA-1 Yankee to create the four-seater. This decision capitalized on the marketplace identification of the Yankee and its derivative the AA-1A Trainer and also resulted in 2/3 parts commonality between the designs, saving development time and production costs.


AA-5 Traveler

The new four-place aircraft, named the American Aviation AA-5 Traveler, was powered by a Lycoming O-320-E2G

and became the Grumman American division. Grumman continued production of the Traveler. 834 Travelers had been produced when production of this model ceased in 1975. A redesign of the AA-5 was undertaken in 1974, with the resulting 1975 model Traveler featuring an aerodynamic cleanup of the engine

and main landing gear fairings. The tail section remained unchanged. As a result of these changes the 1975 Traveler had a cruise speed of . The Traveler was superseded in production the following year by the further refined AA-5A Cheetah.


AA-5A Cheetah

Grumman's engineers felt that the AA-5 design had more speed potential than the original Traveler, even with its 1975 improvements, and so embarked on an aerodynamic cleanup and redesign. Changes were made to the engine cowling and baffling to reduce cooling drag, the exhaust system was redesigned, the main landing gear fairings were further improved, the ventral

range. Fuel capacity was increased from the Traveler's 37 US gallons to 52 gallons, with optional long range tanks, thus increasing its range. The new variant was named the AA-5A Cheetah and was introduced as a 1976 model in late 1975. In keeping with its namesake it was six knots (seven mph) faster than the Traveler with the same Lycoming O-320-E2G powerplant. Because the Cheetah looked very much like the Traveler externally, Grumman's marketing department created a "leaping cheetah" emblem to differentiate it from the earlier AA-5.

in 1978 and the division was renamed Gulfstream American. Gulfstream continued production of the AA-5A until 1979. A total of 900 Cheetahs were produced.


AA-5B Tiger

The final variant of the AA-5 line was the AA-5B Tiger. The Tiger was designed by Grumman engineers and was first produced in late 1974 as the 1975 model. The Tiger was the outcome of the same redesign work on the AA-5 Traveler that resulted in the Cheetah and it was originally little more than the same aircraft with a Lycoming O-360-A4K engine, resulting in a cruise speed. Gross weight was increased from the AA-5/AA-5A's to on the Tiger. Externally the Tiger looked much like the AA-5 Traveler and AA-5A Cheetah so once again Grumman's marketing department came up with a distinctive decal package to differentiate the design – this time a "galloping tiger". While the earlier AA-1s and AA-5s did not change much from year to year the AA-5B Tiger underwent almost continual improvement. As with the AA-5A, the AA-5B was continued in production by Gulfstream when they purchased Grumman's American division. Gulfstream ceased production of all piston-engined aircraft in 1979 and the highly successful Tiger design went out of production after 1323 aircraft had been delivered.


AG-5B Tiger

For eleven years the design was not produced and then in the late 1980s a new company was formed to produce the Tiger. American General Aviation Corporation carried out further design improvements including introducing a new split nose cowling (engine cover) that could be removed without removing the propeller, a new instrument panel, improved exterior lighting, a new fuel quantity indication system, a 28 volt electrical system replacing the older 14 volt system, a new-style throttle quadrant, and improvements to the heat and ventilation systems. Aerodynamic improvements raised the optimal altitude cruise speed from true airspeed to TAS. The redesigned aircraft was put into production under an amended type certificate as the American General AG-5B Tiger. The new company had considered producing AA-1s and AA-5A Cheetahs, but those plans were never fulfilled before it closed its doors in 1993. American General produced Tigers for model years 1990–93 and delivered 181 aircraft in that time. The design has a strong following among pilots and aircraft owners and so, in 1999, a new company was formed to put the Tiger back into production.
