The Cessna 400, now marketed as the TTx, is a single-engine, fixed-gear, low-wing general aviation aircraft built from composite materials by Cessna Aircraft. The Cessna 400 was originally built by Columbia Aircraft as the Columbia 400. From 2013 the aircraft was built as the Cessna TTx Model T240.

The Cessna 400 is the fastest FAA-certified fixed-gear, single-engined piston aircraft in production today, reaching a speed of 235 knots (435 km/h) true air speed at 25,000 feet (7,600 m).

The Cessna 400 was derived from the normally aspirated Columbia 300, which in turn was derived from the Lancair ES kit aircraft.

The 400 is powered by a turbocharged Continental TSIO-550-C engine producing 310 horsepower (230 kW) at 2600 rpm. The 400 features a Garmin G1000 glass cockpit that was later incorporated into the 300 to create the Cessna 350.

The 400's Continental TSIO-550-C engine is capable of being operated lean of peak. Measured in flight at 11,000 feet (3355 m), 50 F° (28 C°) rich of peak turbine inlet temperature, maximum cruise yielded 199 knots (369 km/h) true air speed and 24.7 US gallons (93 L) per hour fuel flow. At the same operating parameters and 50-75 °F lean of peak the 400 was measured at 189 knots (350 km/h) TAS and 17.8 US gal (67 L)/hr (106.8 lb/hr, 67.6 l/hr).

In one review, Richard L. Collins of Flying magazine said of the 400:

The Columbia 400 was marketed with an optional ice protection system, known as E-Vade that was not certified for flight into known icing. The system consists of heat-conducting graphite foil panels on the wing and tail leading edges. These panel areas are heated by 70 volt 100 amp electrical power delivered from a dedicated alternator. The system is controlled by a single switch.
