About the Beechcraft Queen Air 70

Type certificated 1968 Source: FAA Type Certificate Data Sheet

Overview

The Beechcraft Queen Air 70 is the long-wing development of the Queen Air family, certified in 1968. It mates the 65’s fuselage and 340-horsepower Lycoming IGSO-480 engines to the longer, higher-lift wing of the B80, which raises gross weight to 8,200 pounds and gives the best climb in the line without the 380-horsepower engines’ fuel burn. Only about 35 were built, making it the rarest member of the family.

For a buyer, the 70 is the Queen Air for missions that are payload- and runway-limited rather than speed-limited: the long wing lifts more and climbs better than the Straight 65 on the same engines and fuel flow, and the cabin seats up to eleven. The trade is rarity. With so few built, model-specific airframe parts can be harder to source than for the common 65 or B80, while the geared, supercharged IGSO-480 engines carry the same operating discipline and overhaul cost as the rest of the family. It rewards an owner who wants the long-wing capability and will accept a thin parts and knowledge base for the airframe itself.

Key Features for GA Buyers

Long wing on the lighter engines. The B80’s high-lift wing with the 65’s 340 hp IGSO-480s gives the best climb in the family and a higher gross weight than the Straight 65, on the same fuel flow.
Eleven-seat cabin-class layout. The full Queen Air cabin: center aisle, airstair door, separate flight deck, up to eleven occupants.
Shared systems with the family. Engines, gear, and systems are common with the 65 and B80, which keeps the powertrain well supported even where the specific airframe is rare.

Trade-offs

Geared engines plus rarity. The IGSO-480 runs the same 1,400-hour TBO and overhaul cost as the Straight 65; on a 35-airframe type, finding a shop with model-specific experience adds a sourcing layer the common variants do not carry.
Demanding powerplant. The geared, supercharged engines require gentle power handling, and an overhaul costs well above a naturally aspirated twin’s.
Operating cost. Fuel burn and engine economics match the Straight 65 exactly: about 37 gallons per hour combined on a 1,400-hour TBO, among the costliest piston twins to run.
