Cessna 177RG Cardinal RG

The Cessna 177RG Cardinal RG is the retractable-gear, 200 HP member of the Cardinal family — a meaningfully different airplane from the fixed-gear 177B, not a variant of it. Production ran from 1971 to 1978, totaling 1,543 airframes on this certificate (plus a French-built Reims F177RG on its own separate certificate, A26EU, not covered by this page).

The IO-360-A1B6 fuel-injected engine and retractable gear give the 177RG a cruise speed and useful load that put it ahead of the Cessna 172RG Cutlass and into the conversation with entry-level Cessna 182 retractables, at a lower typical purchase price. The hydraulic gear system is electrically backed up and, while more reliable than the 172RG's gear system, still demands diligent maintenance and a careful pre-buy gear swing.

No performance figures on this page are sourced to a handbook. The TCDS gives airspeed limits and weights only (above); cruise speed, range, fuel burn, climb rate, service ceiling and runway distances are all carried, unsourced, from the prior combined page's 177RG comparison row and should be treated as estimates pending a real handbook. A search was made this pass for a free 177RG POH or Owner's Manual (Cardinal Flyers Online's known mdata/poh/ paths for 177rg, several web searches by GAMA-era part number and by model/year, and an NTSB docket titled "Excerpts From Cessna 177RG POH" that could not be retrieved) and none produced a usable document.

Airspeed limits (sourced, TCDS, majority CAS-basis serial block): Vne 169 KIAS, Vno 139 KIAS, Va 113 KIAS, Vfe 96 KIAS. The majority here is thin (57.5/42.5), so rule 23's "take the lower figure" tie-breaker was checked against the majority pick — they agree, since the early block's limits are the lower set on every field.

Standard fuel is 60 gallons usable (61 total), not 50 — this is a genuine, sourced correction of the majority configuration; the 50-gallon tank covers only the first two model years (1971-1972, 21% of production).

*Range and endurance figures are the unsourced carryover discussed above, not a re-verified book number — treat this table as illustrative pending a real handbook. Fuel capacity (60 gal usable) and weights ARE certificate-sourced.

The 177RG's combination of useful load, fuel capacity and gross weight makes it one of the more load-flexible four-seat retractable singles in its class among airplanes of this era — a genuine advantage over the 172RG Cutlass it otherwise resembles in role.

• Flight Training (4): Not a trainer; the retractable gear and higher performance are more airplane than a student needs.
• Backcountry (2): Retractable gear rules out unimproved-strip work.
• Business Travel (7): Genuinely useful for regional business travel at this speed and range.
• Aerobatics (1): Not certified for aerobatic flight.
• Cross-Country (8): The core mission — strong cruise speed, good range, IFR capable.
• Cargo Hauling (5): Useful load of roughly 1,135 lbs and 60 gallons of fuel give real load-carrying flexibility, though the fixed-gear 177B's wide doors are a loading advantage this airplane shares.
• Local Fun (6): A fast, satisfying airplane to fly, though the retractable gear adds a procedural step fixed-gear Cardinal owners don't think about.
• Surveying (5): High wing with no struts, but not the mission this airplane is optimized for.

• Average ($100K-$140K): Mid-time engine, GNS 430W or equivalent, basic autopilot. Standard IFR-equipped retractable.
• Above Average ($140K-$175K): Lower time, GTN 650/750, modern autopilot, well-maintained.
• Premium ($175K-$200K+): Low time or fresh engine, full glass panel, pristine condition. These compete with entry-level Cessna 182 prices.

See Avionics Pricing Reference for current equipment and installation costs.

The Cardinal's cantilever wing limits STOL modifications (no strut to mount fences on); speed modifications are the more popular upgrades on this already-fast airplane.

• Parts availability: Good. Shares substantial parts commonality with the fixed-gear Cardinal; gear-specific parts add a layer of type-specific sourcing.
• Mechanic familiarity: Common, though the hydraulic gear system benefits from type-specific knowledge. Cardinal Flyers Online maintains a list of Cardinal-savvy mechanics.
• Annual inspection cost: $2,500-$4,500 — the gear inspection adds time compared to a fixed-gear annual.
• Engine overhaul: National specialty-shop pricing for the IO-360 family is $45,000 (see reference/engine-overhaul-pricing.md); a local shop reusing serviceable cylinders runs 30-50% under.
• Expensive maintenance items: Gear overhaul ($3,000-$6,000), fuel bladder replacement ($3,000-$5,000 per side), stabilator rebalancing after paint ($1,500-$2,500).

Cardinal Flyers Online (cardinalflyers.com) is an essential resource for both fixed-gear and RG owners. See Maintenance Ecosystem for general context.

The retractable Cardinal commands strong prices driven by its performance. It competes with the 172RG Cutlass (which it outperforms) and approaches Cessna 182 territory.

These bands are unsourced generated figures, not a Vref/Bluebook pull. A dedicated pricing pass (runbook rule 27) was not performed this session.

• Stabilator: Same Cardinal Rule considerations as the fixed-gear airplane apply to any pre-1971 carryover parts, though all 177RGs postdate the original fix.
• AD 77-13-22: Stabilator trim tab bolt inspection and replacement.
• Gear system: The hydraulic retractable gear is electrically backed up and more reliable than the 172RG's system, but still requires diligent maintenance. Gear rigging and hydraulic system condition are critical pre-buy inspection items.
• Fuel bladder leaks: Same wet-wing bladder consideration as the fixed-gear Cardinal.

Pre-Buy Priorities

1. Full gear swing, hydraulic system pressure check, actuator condition.
2. Stabilator balance and hinge bearing condition.
3. Wing spar carry-through corrosion inspection.
4. Fuel bladder condition.

Complex/retractable category, similar to the 172RG Cutlass and Piper Arrow. Expect $2,000-$2,800 annually. The 200 HP IO-360 may trigger high-performance endorsement requirements with some underwriters, though 200 HP is at the threshold rather than clearly above it. Transitioning pilots should expect higher premiums until they accumulate retractable and/or high-performance time. See GA Insurance Underwriting for category details.
