Description
This 1977 Cessna 421C Golden Eagle stands out as a well-cared-for example of a proven twin platform, with a long history of consistent ownership and professional maintenance. Maintained by Air Impressions and kept by the same owner for two decades, it reflects a level of continuity and attention to detail that’s increasingly hard to find in aircraft of this class. Powered by a pair of Continental GTSIO-520-L engines rated at 375 horsepower each, both engines feature aftermarket STCs and are paired with a synchronized propeller system for smoother operation in cruise. This Golden Eagle is configured and equipped for serious IFR flying. The panel centers around a Garmin GNS 530W WAAS-enabled GPS, providing precision approach capability. It’s further supported by a Garmin transponder with ADS-B compliance, active traffic awareness, and a Cessna Nav-O-Matic 800 autopilot with yaw damper. An Insight engine analyzer adds an extra layer of engine monitoring, giving real-time performance data. Inside, the cabin has been completely renovated in 2025. The addition of USB charging ports and audio connectivity, along with a Kenwood AM/FM/CD/Bluetooth entertainment system and cabin speakers, enhances the in-flight experience. The exterior, which was repainted in 2014, received a recent refresh in 2025, complementing the updated interior. This Golden Eagle has a total fuel capacity of 262 gallons and a useful load of 2,350 lbs. It also recently received a new set of tires. With a fresh annual inspection completed in October 2025 and logs available upon request, this aircraft is positioned as a well-maintained, thoughtfully upgraded example of the 421C. Its combination of avionics, capability, and recent interior work makes it particularly appealing for buyers seeking a ready-to-fly aircraft. Will consider trades for aircraft of similar value.
