Description

// DISCIPLINED MX. LOWTIME FACTORY REBUILDS. EXCELLENT VALUE // Donny Gabriel of Mason Amelia proudly presents N45BB, a 1979 Cessna 421C with a strong maintenance history and an ideal foundation for tailoring the airplane to your mission and preferences. When it comes to the 421C, you buy the maintenance, not the airplane. Paint can be refreshed, interiors can be updated, and panels can be modernized, but the true value of these aircraft lies beneath the skin. Caliber maintenance is rarely the product of luck; it's the result of owners committed to preserving the airplane. N45BB is one of those airplanes. Supported by knowledgeable Twin Cessna specialists and respected maintenance facilities with deep experience on the type, it reflects the kind of ownership buyers should seek when evaluating a cabin-class piston twin. Power comes from a pair of Continental GTSIO engines, factory-rebuilt in 2017. The McCauley three-blade propellers were overhauled concurrently, and both engines and propellers have accumulated just 565 hours since. Oil analysis has accompanied every oil change, creating a comprehensive trend history that allows buyers to evaluate engine health over time rather than relying on a single snapshot. Behind the engines, a thoughtfully equipped panel brings modern capability with a pair of Garmin navigators, Shadin fuel flow management, Electronics International all-digital engine monitoring, and dual Garmin transponders with ADS-B In. STC'd wheel covers add a few welcome knots of cruise speed, while the VG kit increases maximum gross weight, improves low-speed handling, and lowers VMC. Finished in Matterhorn White with Gold, Steel Blue Metallic, and Medium Silver Metallic accent stripes, the exterior continues to present exceptionally well with excellent shine and depth. Inside, the 421C truly comes into its own. Even while cruising at flight levels, the pressurization system maintains a comfortable 10,000-foot cabin altitude, and the propellers turn at just 1,800 RPM for a remarkably quiet ride. Seating for up to eight, a refreshment center, and dual executive writing tables make long trips as comfortable as they are capable. To learn more about N45BB, call or text Donny Gabriel today!
