Cessna 337 Aircraft in South Africa

The Cessna 337 Skymaster is a six-seat, twin-engine, push-pull aircraft - two Continental IO-360 engines (about 210 hp each, one fore and one aft on the centerline), retractable gear, approximately 170 knots cruise, 900 nm range, and a ceiling near 19,500 feet. Its centerline-thrust configuration is its defining characteristic: with both engines on the fuselage centerline, neither produces asymmetric thrust on failure, eliminating the Vmc demands that make conventional-twin engine-failure management so critical.

The push-pull centerline-thrust concept. In a conventional light twin, failure of a wing-mounted engine generates strong yaw toward the dead engine and demands immediate, correct rudder input at a critical moment. The Skymaster places both engines on the centerline - losing either produces no yaw, and the aircraft remains easily controllable on one engine. This was the Skymaster's design rationale and remains its primary operational argument.

337 versus the pressurized P337 and military O-2. The civilian 337 family ran from the mid-1960s into the late 1970s across several letter variants. The pressurized, turbocharged P337 adds high-altitude capability; the O-2 is the militarized Forward Air Control variant. The base 337 is the normally aspirated, unpressurized entry to the Skymaster family.

Buy it if you want twin-engine centerline-thrust safety in a six-seat retractable piston twin at lower acquisition cost than pressurized alternatives - particularly for single-pilot IFR, where the Skymaster's benign engine-failure behavior is the key benefit.
