Private Single Engine
Cessna 350 Corvalis
ICAO: COL3
Overview
The Cessna TTx was a high-performance, fixed-gear piston aircraft designed for owner-pilots seeking speed and modern avionics. Derived from the Columbia 400, it combined composite construction with advanced Garmin systems. The aircraft entered service in the early 2010s before production ended later in the decade.

Operational Context
Cessna TTx — high-performance composite piston aircraft
The TTx traces its origins to the Columbia 300 and 400 series developed in the early 2000s. After Cessna acquired the program, it refined the aircraft and reintroduced it as the Corvalis TTx, later shortened to TTx. The airplane featured a low-wing composite airframe with fixed tricycle landing gear and a modern glass cockpit. It entered service under Cessna branding in 2011.
Powered by a Continental TSIO-550-C turbocharged piston engine producing approximately 310 horsepower, the TTx cruises at around 235 knots (435 km/h). Maximum takeoff weight is roughly 3,600 pounds (1,633 kg). The aircraft seats four occupants and is equipped with a Garmin G2000 integrated avionics suite, including envelope protection features and digital autopilot systems.
The TTx targeted pilots seeking near-turbine cruise speeds in a piston platform. Its performance made it one of the fastest fixed-gear single-engine aircraft in production at the time. Production ended in 2018 as Cessna refocused on other segments, but the aircraft remains respected for its speed and advanced cockpit integration.
