GA-7 Cougar
The twin-engine Grumman — two O-320-D1D engines, constant-speed props. Built by Gulfstream American 1978–1979. ~115 built.
The GA-7 Cougar was Grumman's only twin-engine entry, powered by two Lycoming O-320-D1D engines with constant-speed propellers. It shared the bonded honeycomb construction and sliding canopy of the single-engine line but was a fundamentally different aircraft in complexity and mission. Only about 115 were built before Gulfstream American ended production. Parts availability for the Cougar is limited compared to the single-engine models.
