Cessna 172RG Cutlass

The Cessna 172RG Cutlass is the retractable-gear variant of the venerable Cessna 172, produced from 1980 to 1985. Cessna built approximately 1,191 Cutlass RGs during this period, introducing the model just as the general aviation market entered its steep 1980s decline. The 172RG was created primarily to serve as an affordable complex aircraft trainer — its retractable landing gear, constant-speed propeller, and 180 HP engine meet the FAA requirements for the complex aircraft endorsement needed for the Commercial Pilot certificate.

The Cutlass delivers roughly 15-18 knots of cruise speed improvement over a standard fixed-gear 172, thanks to the cleaner aerodynamics of retracted gear. It shares the same airframe DNA, docile handling, and high-wing visibility that made the 172 the most popular trainer in history, but adds meaningful systems complexity. Despite its training role, the 172RG is a capable cross-country machine with 62 gallons of fuel and over 700 nm of range. Its reputation, however, is complicated by a well-documented history of landing gear system failures.

All production years share the same engine, propeller, and gear system. Differences between years are limited to interior trim, avionics packages, and minor system refinements. The 172RG II designation reflects a marketing update, not an engineering change.

The 172RG cruises at 135-140 KTAS at 75% power, compared to 120-122 KTAS for a contemporary fixed-gear 172P. The 15-18 knot gain comes entirely from the retracted landing gear reducing parasite drag. Rate of climb at 800 fpm is modestly better than a fixed-gear 172 but nothing dramatic — the extra 20 HP is largely offset by the roughly 170 lbs of additional empty weight from the gear mechanism and hydraulic system.

Real-world pilots report that the book cruise numbers are achievable. Fuel burn runs 9.5-10.5 GPH at 75% power. Reducing to 65% power drops burn to about 8.5 GPH with cruise speeds around 128-130 KTAS, which represents the best efficiency point for cross-country work.

The 172RG handles almost identically to a standard 172, which is both its strength and its purpose. There are no surprises in the transition from fixed-gear to retractable except the gear and prop management procedures. Service ceiling of 16,800 feet is adequate for mountain crossing, though climb performance at altitude thins considerably at the 172RG's power loading.

The 172RG's 1,023-lb useful load is generous for a four-seat single, but full fuel (372 lbs) leaves only 651 lbs for occupants and baggage. With two 200-lb adults and 50 lbs of bags, full fuel works comfortably and delivers the airplane's full 714 nm range. Four adults requires a significant fuel reduction, cutting range to under 500 nm — still a very usable number for most missions. The 62-gallon fuel capacity is the 172RG's cross-country ace, providing nearly 6 hours of endurance at economy cruise.

• Flight Training (7): The primary purpose of the 172RG's existence. It is the most accessible complex endorsement trainer in general aviation. Familiar 172 handling minimizes transition risk while teaching gear and prop management. Scored 7 rather than higher because modern flight training increasingly uses glass-cockpit fixed-gear aircraft, and the 172RG's gear reliability issues make fleet operations expensive.
• Backcountry (2): Retractable gear is a liability on unimproved strips. Prop clearance is adequate but the gear doors and mechanism are vulnerable to FOD. Not suitable.
• Business Travel (5): Moderate speed (140 KTAS) and good range (714 nm) make it functional for regional trips, but the single-engine speed falls short of typical business travel expectations. The useful load of 1,023 lbs accommodates full fuel plus three adults.
• Aerobatics (1): Not certified for aerobatic flight.
• Cross-Country (7): A genuinely capable cross-country machine. The 62-gallon fuel capacity and 140-knot cruise provide a solid speed/range combination. IFR capable with standard avionics fit.
• Cargo Hauling (3): Useful load is decent at 1,023 lbs, but the cabin volume is standard 172 — acceptable for personal cargo, not suited for commercial hauling.
• Local Fun (5): Flies like a 172, which is pleasant but not exciting. The retractable gear adds workload that diminishes casual flying enjoyment without adding any thrill.
• Surveying (5): High wing provides good ground visibility, but the constant need to manage gear and prop systems distracts from observation tasks. A fixed-gear 172 or 182 is better suited.

Most surviving 172RGs were flight school aircraft and have been through multiple panel upgrades. Common configurations by price tier:

• Budget ($80K-$100K): Original steam gauges, King KX-170B or KX-155 radios, basic IFR with an older GPS (KLN-89B or GNS 430 non-WAAS). Functional but dated.
• Mid-range ($100K-$140K): Garmin GNS 430W or GTN 650, basic autopilot (KAP 140 or S-TEC 30), ADS-B compliant. Capable IFR platform.
• Premium ($140K-$195K): Garmin G500 TXi or Aspen PFD, GTN 750, GFC 500 autopilot, full ADS-B In/Out. These are typically low-time owner-flown aircraft rather than ex-trainers.

The 172RG shares panel dimensions with the standard 172 family, so all Cessna 172 avionics STCs and mounting solutions apply. See Avionics Pricing Reference for current equipment and installation costs.

The 172RG does not benefit from engine upgrade STCs to the same degree as fixed-gear 172s — the O-360-F1A6 at 180 HP is already the right engine for this airframe. Speed modification kits are the most popular upgrades, as even small cruise improvements are meaningful on an airplane purchased specifically for its retractable-gear speed advantage.

• Parts availability: Good. The 172RG shares most structural and engine parts with the broader 172 family and the O-360 engine line. Gear-specific parts (power pack, actuators, pivot assemblies, hydraulic lines) are available but can be expensive and occasionally on backorder.
• Mechanic familiarity: Common. Most A&Ps have worked on 172s, but the retractable gear system is a specialty item. Seek an A&P with specific 172RG experience for annual inspections and gear work.
• Annual inspection cost: $2,500-$4,500 depending on findings. The gear system inspection adds meaningful time and cost compared to a fixed-gear 172 annual.
• Gear overhaul: Budget $3,000-$8,000 for a comprehensive gear overhaul including actuators, seals, bushings, and rigging. This is a periodic expense unique to the retractable variant.
• Engine overhaul: $45,000-$35,000 for a field overhaul of the O-360-F1A6. Factory reman available from Lycoming at higher cost.

See Maintenance Ecosystem for general maintenance cost context.

The 172RG market has historically lagged behind the broader used aircraft market. Values have been suppressed by the airplane's reputation for gear problems, the large number of ex-flight-school airframes with high total time, and the niche appeal of a complex single that is slower than many fixed-gear alternatives (e.g., Mooney M20C).

Key price drivers:

• Gear-up history: An airplane with a well-documented gear-up repair is not necessarily worth less than one without, provided the repair was done properly. But poorly documented repairs or multiple gear-ups are significant discounts.
• Total time: Many 172RGs have 5,000+ hours from flight school use. High-time airframes with well-maintained engines are still serviceable but command less than low-time owner-flown examples.
• Engine time: Standard valuation applies — see Aircraft Valuation Methodology. Fresh overhauls add proportionally to value.
• Avionics: The spread between a steam-gauge 172RG and a glass-panel example can be $50K+. Avionics upgrades are the primary differentiator in the mid-to-upper price range.

Critical ADs

• AD 2001-06-06: Main landing gear pivot assembly inspection. Requires inspection for cracks in pivot assemblies and installation of new bushings. If cracks are found, pivot replacement costs $4,600-$7,600 depending on whether one or both sides need replacement. This is the most significant AD on the 172RG and represents roughly 10% of the airplane's value.
• AD 84-26-02: Nose gear actuator inspection for proper shimming. Incorrect shimming can prevent nose gear extension.
• AD 2012-18-10: Landing gear side brace bolt inspection and replacement.

Chronic Problems

The electro-hydraulic landing gear system is the 172RG's defining maintenance challenge. The system uses a hydraulic power pack that cycles periodically during flight to maintain pressure. Key failure modes include:

• Hydraulic line rupture: A leak anywhere in the system will cause the power pack to pump all fluid overboard before the pilot realizes the pump has been running too long. This failure mode results in a gear-up landing with no manual backup that can overcome a drained system.
• Power pack failures: The electric motor and hydraulic pump assembly is a common maintenance item. Expect rebuild or replacement at some point during ownership.
• Gear position indication: Micro-switch failures causing false unsafe-gear indications are routine nuisances.
• Gear door actuator rod ends: Wear and play in the linkages cause gear door fit issues and can prevent clean retraction or extension.

A very large percentage of 172RGs have experienced at least one gear-up landing during their service lives. Pre-buy inspections must include a thorough gear system examination by an A&P familiar with the type. Check gear pivot assemblies, hydraulic lines, power pack condition, actuator rod ends, and micro-switch rigging. A properly maintained gear system is reliable, but deferred maintenance compounds quickly.

The 172RG falls into the complex/retractable gear insurance category, which carries approximately 30% higher premiums than an equivalent fixed-gear 172. For a private pilot with 250+ hours and retractable time, expect annual hull and liability premiums of $1,800-$2,500 depending on hull value and experience. See GA Insurance Underwriting for category details.

New retractable-gear pilots should expect significantly higher premiums or open-pilot-warranty exclusions until they accumulate 25-50 hours of retractable time. Some underwriters require a checkout with a CFI before binding coverage.

The 172RG's gear-up landing history affects the insurance market broadly — underwriters price the fleet risk, not just individual airframes. This is one reason 172RG values have historically been suppressed relative to fixed-gear 172s that cost more to insure per dollar of hull value.

Flight schools operating 172RGs face particularly steep insurance costs due to the combination of retractable gear, student/low-time pilots, and high utilization. Many training operations have shifted to Piper Arrows or simply use simulators for complex endorsement training to avoid 172RG insurance premiums.
