Cessna 310Q Price & Cost

Cessna 310Q Price Guide

Key price factors: engine time to overhaul, year and airframe hours, avionics, damage history and logbook completeness — see the buying guide below for the full pre-purchase checklist.

Cessna 310Q Cost of Ownership estimate
Fuel (26.0 GPH × $6.20, 100 hrs)$16,120/yr
Annual Fixed (hangar, insurance, annual)$26,000/yr
Variable (per hour)$290/hr
Engine Overhaul (every 1,500 hrs)$38,000
Estimates at 100 flight hours/year. Actual costs vary by usage, location and insurance.

Two Continental IO-520 engines at around 26 gph combined make the 310Q one of the most expensive classic piston aircraft to fuel. Two full overhaul events, doubled magneto inspection, two prop governors, and retractable-gear hydraulics compose the maintenance budget. Insurance reflects both complexity and the multi-engine pilot-in-command requirement. The operating premium over a fast turbocharged single is real, offset by twin redundancy and useful-load advantage. Maintaining both engines on the same schedule matters - deferred work on either IO-520 creates asymmetric engine-condition risk.

Buying a Used Cessna 310Q

Buying a Cessna 310Q comes down to a focused pre-purchase checklist — here is what matters most on this model:

What to check before buying

The Cessna 310Q is a six-seat, retractable-gear twin powered by two Continental IO-520 engines (285 hp each) producing approximately 195 knots cruise, 900 nm range, and a 20,000-foot service ceiling. It is a conventional piston twin in the classic 310 line - one of the fastest and most capable non-pressurized piston twins of the classic era, used for personal transport, charter, and instrument training.

310Q performance position. At 195 knots cruise with around 1,800 lbs useful load, the 310Q matches turbocharged piston singles in speed while carrying more payload and adding twin-engine redundancy. Against the Cessna 337G Skymaster, the 310Q is roughly 20 knots faster with greater useful load - at the cost of asymmetric-thrust handling and conventional twin operating economics.

Twin-engine handling. Unlike the Skymaster's centerline-thrust layout, the 310Q is a conventional twin: an engine failure creates asymmetric thrust requiring immediate rudder input and specific Vmc awareness. Pilots transitioning from singles need multi-engine training that covers Vmc discipline - the 310Q is not forgiving without proper instruction, though it is capable and reliable with a well-trained crew.

Continental IO-520 engines. Two IO-520s at about 26 gph combined is the 310Q's primary operating cost. Both require synchronized maintenance intervals, overhaul planning, and separate ignition work. Engine condition is the critical pre-buy item - single-engine buyers examine one powerplant; 310Q buyers must evaluate two.

Buy it if you need six seats with near-200-knot cruise and twin-engine safety margins, hold a multi-engine rating with conventional-twin competency, and can sustain the economics of two IO-520s.

Frequently Asked Questions — Cessna 310Q

What is the Cessna 310Q?
The 310Q is an early-1970s member of the Cessna 310 family — a four-to-six-seat twin-engine piston aircraft with distinctive wing-tip fuel tanks and refinements over earlier 310s, Cessna's classic light twin.
How much does a Cessna 310Q cost?
Used 310Q prices vary with engine times, avionics and condition. See the live price range and median above.
What are the Cessna 310Q specifications?
The 310Q cruises around 190 to 220 knots with a typical range of roughly 900 to 1,200 nautical miles on two Continental engines, seating four to six. See the specifications for exact figures.
How many seats does a Cessna 310Q have?
Four to six, depending on the interior configuration.
What engines does the Cessna 310Q use?
Two Continental IO-470 or IO-520 engines. Engine time since overhaul is a key value factor.
What is the difference between the 310Q and 310R?
The 310R is the later, final version with a longer nose for more baggage and a higher useful load; the 310Q is the slightly earlier model. Both are classic Cessna light twins.
Is the Cessna 310Q still in production?
No — 310 production ended in 1980. The 310 is supported by a used fleet and parts network for owner-flown and utility use.
