About the Cessna 340
Type certificated 1975
Overview
The Cessna 340 is a pressurised, six-seat cabin-class piston twin, the entry rung into pressurised twin-engine flying between lighter twins like the Cessna 310 and the larger Cessna 414 Chancellor and 421 Golden Eagle. The common 340A, introduced in 1976, carries two turbocharged Continental TSIO-520-NB engines of 310 horsepower each and a 4.2 psi pressurisation differential that holds a roughly 10,000-foot cabin in the high teens. A center-aisle, club-seated cabin is entered through an airstair door, and the airplane cruises near 229 knots on about 38 gallons per hour combined.
For the buyer, the 340 is the entry rung into pressurised cabin-class flying: a sea-level-feeling cabin in the high teens at piston acquisition and avgas running cost. The trade is payload. With the tanks full the 340 carries three to four adults, so it works best as a four-place airplane on its longest legs. Many airframes carry aftermarket RAM Series IV through VII conversions that raise horsepower, useful load, and climb, and a sorted, RAM-converted example with a working yaw damper is the one to want.
Key Features for GA Buyers
- Pressurised comfort. The 4.2 psi differential holds the cabin near 10,000 feet into the low flight levels, cutting pilot and passenger fatigue on long flights up high.
- Cabin-class cabin. An airstair door, center aisle, and club seating give the 340 a cabin-class layout that the unpressurised, lighter 310 does not offer.
- Turbocharged altitude performance. Twin TSIO-520-NB engines sustain a roughly 229-knot cruise into the flight levels, above much of the weather.
- RAM conversions. Many airframes carry RAM Series IV through VII upgrades that improve power, useful load, and climb over the stock airplane.
Trade-offs
- Fill the seats or fill the tanks. Six seats and large tip-tank fuel capacity rarely combine; full fuel typically leaves payload for three to four adults.
- Systems complexity. Pressurisation, turbochargers, and a multi-tank fuel system raise maintenance and recurrent-training demands well above an unpressurised light twin.
- Yaw damper effectively mandatory. Like other Cessna twins of the era, the 340 is prone to yaw oscillation in turbulence, and most owners treat a working yaw damper as required equipment.
