Cessna 337 Skymaster

Cessna · United States · first flew 1961 · light aircraft

The Cessna 337 Skymaster is a twin-engine light aircraft with a unique push-pull centreline-thrust configuration, with one engine in the nose and one in the rear fuselage. This eliminates the asymmetric thrust problems of conventional twin-engine aircraft during single-engine failures.

Unique centreline-thrust layout, twin-boom tail with twin vertical fins, and high wing make the Skymaster instantly recognisable. Nothing else in its class has this configuration.

History

Cessna developed the Skymaster in the late 1950s to offer twin-engine safety without the handling complexity of asymmetric thrust. The Model 336 fixed-gear prototype flew in 1961; the retractable-gear 337 followed in 1964. A military observation version, the O-2 Skymaster, served extensively in Vietnam for forward air control. Over 2,900 examples of all variants were built.

Variants

Model 336 (fixed gear), 337 (retractable), 337 Pressurised Skymaster, and the military O-2A/B. Reims Aviation produced the FTB-337 in France for European markets.

Where you'll see it

Popular with private owners, air taxi operators, and in missionary aviation. The O-2 served USAF and South Vietnamese forces in Vietnam and is still used by some air forces.
