Cessna 310R: The Sleek Twin That Took General Aviation Up a Notch
The Cessna 310R was the final and most refined version of Cessna’s first post-war twin-engine aircraft. Known for its sleek lines, distinctive tip tanks, and well-balanced performance, the 310R brought high-end capability and comfort to the personal and business aviation market.
From its initial introduction in 1954 to the end of production in 1980, the Cessna 310 line evolved into a fast, capable twin that found a following among private owners, charter operators, and law enforcement agencies.
From the 310 to the R: A Timeline of Refinement
Cessna debuted the original 310 in 1954 as a lightweight twin powered by Continental O-470 engines. Early models featured straight tails, "straight" tip tanks, and spartan interiors. Over the years, the aircraft underwent continual refinement in performance, capacity, and systems.
The 310R, introduced in 1975, brought the line to its peak:
-
Continental IO-520-M engines, producing 285 horsepower each
-
Longer nose for improved baggage space and CG balance
-
Redesigned canted tip tanks (“tuna tanks”) for increased fuel capacity and range
-
Optional known ice protection, radar pods, and weather systems
-
Max gross weight increased to 5,500 lbs
-
Top cruise speed of approximately 200–205 knots
-
Useful load: around 2,000 lbs, depending on configuration
By the time production ended in 1980, over 6,300 310s had been built, with the R-model becoming the most sought-after in the fleet.
A Pilot’s Twin
The 310R developed a reputation for being a “pilot’s airplane.” Fast, stable, and responsive, it was a step up from light singles or less aerodynamic twins. Handling was smooth and well-coordinated, with enough weight to give it a solid, stable ride — especially in IMC.
Pilots praised:
-
Trim authority and elevator response
-
Clean engine-out performance (for its class)
-
Excellent visibility from the cockpit
-
Strong climb rate when light
-
Confidence-inspiring approach stability
With proper training, the 310R offered private owners a solid IFR platform that could also serve for business trips or weekend flying with a full load of passengers and baggage.
Operational Roles and Real-World Use
Beyond private use, the Cessna 310R saw service in:
-
Law enforcement and surveillance
-
Air taxi and charter ops
-
USAF as the “Blue Canoe” (U-3A/B) for liaison and light transport duties
-
Aeromedical operations in remote areas
Its long range, fuel efficiency (for a twin), and press-optional upgrades made it attractive for missions that required speed and versatility without jumping into cabin-class aircraft.
The Twin That Still Turns Heads
Despite ending production in 1980, the Cessna 310R remains popular on the used market. A well-maintained model offers exceptional value for pilots looking for a fast, capable twin without stepping into turboprop territory. Many have been upgraded with glass cockpits, aftermarket STCs, or custom interiors — but the airframe’s DNA remains unmistakable.
