Cessna 310 Buyer’s Guide — Classic Twin Performance
The Cessna 310 offers twin-engine performance and style. Here’s what ownership of this classic light twin really looks like.
Why the 310
The Cessna 310 is one of the most iconic light twins ever built. With 195+ knot cruise speeds, distinctive tip tanks, and the solid build quality Cessna is known for, the 310 turns heads on every ramp. Powered by twin 285 hp Continental IO-520 engines, it delivers genuine twin-engine performance and redundancy. Production ran from 1954 to 1981, and the 310 remains one of the most recognizable silhouettes in general aviation. It is a serious cross-country machine that makes long trips comfortable and fast.

What to Know
Production spanned nearly three decades, so model selection matters. Later models — the 310R and 310R II — are the most desirable, with canted tip tanks, improved systems, and turbocharged options. The T310R turbo models can reach FL250 for weather avoidance and tailwind hunting. Avoid very early straight-tail models from the 1950s — parts are increasingly scarce and the systems are outdated. Mid-production models (1970s) offer a good balance of modern systems and reasonable prices. Any 310 you consider should have complete logbooks and a well-documented maintenance history.
Known Issues
The tip tank fuel system adds complexity — fuel management requires attention and the interconnect plumbing can develop leaks. Exhaust system cracks are expensive to repair on six-cylinder engines, especially when both sides need attention simultaneously. Continental IO-520 overhauls run $35,000–$45,000 per engine. Landing gear actuators require periodic overhaul. Corrosion on the belly and wing attach points is common on aircraft that lived outside. The spar carry-through structure inspection is critically important on the prebuy — this is a load-bearing structure that is expensive to repair if compromised.
Ownership Costs
Purchase prices range from $60,000–$140,000 depending on model year and condition. Insurance runs $5,000–$12,000/yr — twin-engine insurance is expensive, and multi-engine time requirements are strict. Fuel burn is 24–28 gph total at cruise, costing $160–$200/hr in fuel alone. Annual inspections run $6,000–$14,000, and two engine overhauls will cost $70,000–$90,000 combined when the time comes. Budget $40,000–$55,000/yr at 100 hours of flying. Twin ownership is not for the faint of wallet.
Our Verdict
The Cessna 310 is a gorgeous airplane that turns heads on every ramp and delivers serious cross-country performance. But twin-engine ownership costs are brutal — you are essentially maintaining two airplanes worth of engines, props, and systems in one airframe. Make sure you have the budget to do it right and fly enough hours to stay proficient on single-engine procedures. If the finances work, the 310 rewards you with speed, style, and a flying experience that single-engine airplanes simply cannot match.
