Understanding the unique push-pull Skymaster design and why it remains a compelling choice for serious pilots.
The Cessna 337 Skymaster represents a unique solution to the challenges of light twin-engine aircraft. By placing one engine in the nose and another in the rear fuselage, both mounted on the aircraft's centerline, Cessna eliminated the critical engine problem that complicates conventional twin operations.
In a conventional twin, losing one engine creates asymmetric thrust that can lead to loss of control if not managed properly. The Skymaster's centerline thrust configuration means that losing either engine results in straightforward, predictable handling with no asymmetric thrust to manage.
This design philosophy earned the Skymaster the nickname "the twin-engine aircraft that flies like a single" - combining the safety and redundancy of twin engines with handling characteristics closer to a high-performance single.
Cessna began development of the Model 336 in the early 1960s, seeking to create a twin-engine aircraft that would be easier and safer to fly than conventional twins. The original 336 featured fixed landing gear and was introduced in 1963.
The Model 337 introduced retractable landing gear in 1965, improving performance and giving the aircraft its distinctive profile. The 337C variant, produced from 1968-1970, featured refinements including improved engine cooling and updated systems. Production continued through various models until 1980, with over 2,900 aircraft built.
The U.S. Air Force operated the O-2 Skymaster (military designation for the 337) extensively during the Vietnam War for forward air control missions. The aircraft's reliability, visibility, and ability to operate from short fields made it ideal for this role. Military Skymasters accumulated millions of flight hours, proving the design's durability.

The Skymaster's proven design is well-supported by experienced mechanics nationwide. N2645S benefits from expert care by an A&P/IA with over 3,000 hours of Skymaster experience, ensuring proper maintenance of this reliable twin. The type's straightforward systems and robust construction make it an excellent long-term ownership proposition.
The Skymaster delivers twin-engine safety at remarkably efficient operating costs. Fuel consumption of 20-25 GPH combined is significantly lower than conventional twins like the Baron or Seneca. Insurance costs are typically 20-30% less than standard twins thanks to the forgiving centerline thrust configuration. You get true multi-engine redundancy and safety without the premium operating costs of conventional twins.
The Skymaster is renowned as the easiest twin to fly, making it perfect for pilots transitioning from singles. The centerline thrust eliminates critical engine concerns and VMC rollover risks that plague conventional twins. Most pilots complete transition training in just 5-10 hours. The forgiving handling characteristics and no asymmetric thrust issues mean you focus on enjoying twin-engine safety and capability, not wrestling with complex emergency procedures.
The Cessna Skymaster enjoys strong community support through active type clubs and owner groups. The Cessna Pilots Association and dedicated Skymaster forums provide valuable resources for maintenance, modifications, and operational advice.
Parts availability remains good for most components, with both OEM and aftermarket suppliers supporting the fleet. The aircraft's long production run and military service history ensure continued support for the foreseeable future.
This particular 337C represents an exceptional example of the type, combining low total time, modern avionics, mid-time engines, and expert type-specific maintenance. The substantial investment in glass cockpit technology and careful restoration make it a turnkey aircraft ready for serious cross-country IFR operations.
