1969 Cessna 337D
- January 26, 2023
The Cessna 337 Skymaster is one of the most innovative approaches to twin-engine aircraft design in general aviation history — a push-pull configuration that places both engines on the aircraft's centerline, completely eliminating the asymmetric thrust problem that makes conventional twin-engine aircraft training so challenging and single-engine flight so demanding. In a conventional twin, engine failure requires immediate, forceful rudder application to counteract the yawing moment from the operating engine. In the 337, because both engines are on the centerline, an engine failure produces no directional tendency whatsoever — the pilot simply deals with reduced power, not a handling emergency. This characteristic makes the 337 one of the safest multi-engine aircraft ever certified, and one of the most genuinely accessible for pilots transitioning from single-engine backgrounds.
The US Air Force operated the O-2A and O-2B Skymaster in the forward air control (FAC) role during the Vietnam War — flying low and slow over contested territory to direct ground-attack aircraft onto targets. The O-2's push-pull configuration, ability to fly on one engine without directional challenge, and excellent low-speed visibility made it well-suited for this demanding mission. Military surplus O-2s that transitioned to civilian operation are occasionally available on the pre-owned market as collector aircraft.
