Overview

The Cessna 177RG Cardinal RG is the retractable-gear, 200 hp evolution of the Cardinal line, produced from 1971 to 1978. Cessna’s intent was to give the Cardinal airframe a cruise advantage commensurate with its visual sophistication and to position it against the Piper Arrow and Beechcraft Sierra in the complex four-seat retractable category. The 200 hp fuel-injected Lycoming IO-360 and tucked gear produce roughly 148 KTAS, around 24 knots faster than the fixed-gear 177B.

The cabin proposition is unchanged from the fixed-gear sibling: strutless cantilever wing, pilot forward of the wing’s leading edge, 90-degree doors, low flat cabin floor. Among production four-seat retractables in this performance class, the RG is the only high-wing option, which is the defining point of differentiation against the Arrow and Sierra. Insurance treats the RG as a complex high-performance single, and the type carries a complex endorsement requirement. Fleet age and the maintenance demands of the retractable gear system are dominant ownership-cost factors and meaningfully shape used-market pricing, so the buyer who wants this airplane is buying the visibility and the high-wing layout, and accepting the gear-system upkeep that comes with them.

Key Features for GA Buyers

• Cruise Speed. 148 KTAS from a 200 hp IO-360 represents a step-change improvement over the fixed-gear Cardinal and Skyhawk, useful for cross-country missions in a way the fixed-gear versions are not.
• High-Wing Visibility in the Retractable Class. No other production four-seat retractable offers the strutless high-wing visibility geometry. Against the Arrow and Sierra, this is the defining structural advantage.
• Cabin Access. The 90-degree doors and absence of a wing strut to step over carry over from the fixed-gear Cardinal: notably easier boarding than the low-wing retractable competition.
• Long-Range Fuel Capacity. 60 gallons usable (1973 and later) gives the RG a genuine cross-country range envelope at sensible payload, particularly relative to the smaller tanks the fixed-gear Cardinal often shipped with.

Trade-offs

• Gear System Complexity. The 1971 and 1972 hydraulic-electric gear systems are maintenance-intensive; later simplified hydraulic systems are preferred. Gear-related squawks dominate the type’s maintenance signature and shape both insurance and pre-purchase inspection scope.
• Useful Load Math. MTOW is 2,800 lb, but the retractable gear mechanism adds meaningful empty weight. Full long-range fuel typically constrains the cabin to two or three adults plus baggage rather than four.
• Wing Spar Inspection Burden. Like the fixed-gear Cardinal, the RG falls under AD 2023-02-17 for the carry-through spar eddy-current inspection, roughly $3,100 to $3,800 recurring, with a far higher on-condition replacement exposure. Budget for it in pre-purchase and ongoing.
• Fleet Age and Parts Availability. Production ended in 1978. Airframe parts share the fixed-gear support base, but gear-system parts specifically are a thinner sub-market and a real consideration in long-term ownership planning.
