Cessna R182RG

Turn a straight-legged Skylane into a retractable and youll gain speed yet lose none of the airplanes roominess, range and utility.

Whats the use of takng a Chevy Impala, throwing on some extras and pretending its a Jaguar?


Some pilots wondered the same thing when Cessna took that sedan of airplanes, the roomy, drafty but handy straight-legged 182 and gave it folding gear and the option of a turbo for that big Lycoming O-540.

Those who love the 182s all-around utility and mostly good manners had no problem understanding what Cessna had done. The airplanes decent but less-than-stellar cruise speed had been its big drawback but, in one bold stroke, Cessna had made the airplane go 15 knots faster at the same 12 to 14 GPH fuel burn.

No wonder the model sold well initially, until the industry hit a brick wall within a few years of the retractable Skylanes introduction.

Model history
Cessna introduced the R182 Skylane RG in 1978, making almost 600 of them that year. The total run, including the turbocharged version, would reach 2032 through 1986, when a mere nine were built before Cessna took a powder from the single-engine market. Thats not many airplanes compared to all the M20 Mooneys or Bonanzas out there.

To create the model, Cessna took the popular 182 and gave it a variation of the folding electro-hydraulic gear used on the 200-HP Cardinal RG, which had been introduced two years before. The R182 (thats the correct type designation, not 182RG) got a bigger Lycoming than the 182s 230-HP Continental O-470; the retractable came with the Lycoming O-540-J3C5D, which required adding four inches to the length of the cowling. The turbo option was offered on the 1979 model, when Cessna first began building the line with integral fuel tanks instead of those troublesome bladders, which leaked and trapped water in wrinkles. The integral tank never needs resealing or repair. Some 727 R182s and TR182s were built that year. Fewer than half that number were built during the 1980 model year and the total fell off each year thereafter.

Aside from the switch from bladders after 1978, Cessna made only minor changes in the airplane through its eight-year run. The alternator and over-voltage sensor were swapped for an alternator control unit and the high-voltage warning light was switched to a low-voltage light in 1979. The next year a new latch and pin system was introduced to reduce the notoriously drafty fit of the doors-there are two on the Skylane, which is as celebrated for its ease of entry and loading as it is reviled (or patiently accepted) for its so-called “gappy” Cessna construction and fit.

In 1980, an avionics cooling fan became standard and the oil cooler was relocated from the left forward baffle to the firewall. Also, the battery was moved from the firewall to the less hostile environment of the tail cone and for easier access. A new muffler for better cabin heating, especially in the rear seats, addressed another Skylane complaint.

In 1983, Cessna replaced the amber “gear up” light, which stayed on if the gear did not lock down, with a red “gear in transit” light, which stayed on whenever the gear motor was running.

With the gear tucked up, the Skylane will build up speed when the nose drops. It helps that the first 10 degrees of flaps can extend at 140 knots. In 1983, Cessna beefed up the flaps further so they can be lowered to 20 degrees at up to 120 knots.

The wing root ventilators were redesigned in 1980, but they are known for getting loose with age, spraying water into the cockpit in rain and popping open all by themselves. Duct tape over the wing inlets is the standard field solution. Skylane windshields also tend to leak and the R/TR182 is no exception. The only solution that works is removing the windshield and resealing it. Watch for shops that use silicone sealant instead of the proper felt stripping. Windshields expand and contract; hardened silicone does not.

The R/TR182 has no main gear doors. But it does have nosegear doors and early on they occasionally caught the cowling skin and got stuck. A 1983 redesign addressed the problem. In 1984, the airplane got new composite fuel caps and rear-seat shoulder harnesses as standard equipment. Dual controls became standard instead of optional that year, but whos seen any single-control Skylane RGs around?

The Skylane retractable is a solid cross-country airplane with a 150-knot cruise commonly reported at a fuel burn of 12 to 14 GPH. With its 88-gallon usable standard tanks (on 1979 and later models), it can go far. Its range and its 1200- to 1300-pound useful load give it lots of flexibility as a good hauler.

Those big tanks, which provide better range than early Mooneys and Bonanzas, leave less of a useful load than a 250-HP Piper Comanche with full tanks-but that comparison doesnt do justice to the airplanes flexibility.

With full fuel, four “standard” FAA grownups can go on a long trip-close to 1000 miles, depending -and share a single overnight bag. Fly with less fuel and you can carry just about anything you can fit into the airplane and still fly for hours. Weve said it before and cant resist saying it again: Your bladder cant last as long as the fuel supply when you cruise an R182 at lower power settings, say 55 to 60 percent.

Another big attraction is that the R182, with its big, fat wing, big flaps, high flap extension speeds and good prop clearance, is just as handy getting into and out of smaller airports and rougher fields as it is keeping up the speed on the ILS into a Class Bravo airport even as it drops full flaps at the last minute and gets out of the way at the first turnoff.

Try that in a Mooney. A few owners do complain, however, that because the tires on the RG are smaller and inflated to higher pressures than those on the fixed-gear Skylane, it can be a little squirrelly in crosswinds and harder to control on the runway.

Its 235 horses also take some pilots by surprise when they pour on the coal: A Mooney or Arrow pilot used to 200 HP might be surprised by the left-turning tendency of the Skylane RG at full power and high pitch. These traits, and the heaviness of the elevator, may explain a number of runway and go-around crack-ups over the years.

Comparisons are not made between the R182 and the Bonanza, which pilots do not consider a lower-priced choice in the used market. So Aviation Consumer a few years ago conducted a side-by-side flyoff between the R182 and a 201. It found the R182 had the better climb rate and more dexterity getting into and out of a variety of airports. The Cessna hauled more, both in weight and volume, and was a little faster than the sleek 201, but of course at 20 to 40 percent more gallons per hour.

The turbocharged version is significantly faster after its easy climb into the low teens, where it can achieve 165 knots TAS and more at higher altitudes. The normally aspirated R182 climbs well, too, with 1000 FPM typical at lower altitudes at gross weight and standard temperature. The turbo, its adoring pilots have told us, will lope up to FL 200 at 1000 FPM the whole way up.

Handling, Cabin
In the air, the 182RG is a gentle, forgiving bear with a solid ride and feel. An Avcon writer used it to practice airwork for his CFI certificate and found it gentler than a 172, unwilling to bite even in a fully cross-controlled stall. Still, it requires some skill to fly well. It is not a feet-on-the-floor airplane like the Cherokee and its derivatives.

Pilots who dont use as much rudder to help roll out of a turn as they used rolling in will wallow all over the sky. (They never seem to notice how far the ball slid outside the cage.) The RG likewise needs nimble and firm rudder work on and near the runway to keep the nose straight on takeoff and in crosswinds.

Most notorious is the heavy elevator feel, something youd expect pulling back on a DC-3 yoke. The heavy pitch and the Skylanes brick-like descent rate with full flaps and gear out-something youd expect of the Space Shuttle-have led to a fair number of hard landings and runway loss-of-control accidents. Dont try to land power-off with full flaps; the timing of the roundout and flare will be so critical as to invite a hit or a drop. Keep some power in. Watch out especially for forward-CG landings, with full fuel and only two aboard in the front seats. And before buying a used Skylane RG, check the logs, gear and the firewall carefully for evidence of damage.

The Skylane cabin is famously roomy and easy to access with a wide door on each side and windows that open on both, in most models. The baggage door is low to the ground and convenient. That big box of a cabin, however, flexes and the door and windshield fit can get sloppy over the years. That makes for drafts and water leaks. The original seats are okay except for their cheesy plastic and fabric. They are adjustable in height and seatback angle with lots of parts and pieces. Watch out for broken adjusters as well as worn seat tracks, the subject of a well-known AD affecting many Cessna singles.

A look at the past 10 years of Service Difficulty Reports (1996 to 2006) confirms that landing gear malfunctions and problems continue to top the list of R/RT182 maintenance woes. Out of 85 SDRs during that period, 17 or 20 percent had to do with sheared bolts, failed downlock pins, cracked pivot assemblies, stuck doors and the like.

Thats an improvement over the rate seen in earlier SDR reviews. Owners who wrote us recently had no complaints about the gear. One said its better for grass strips than the fixed-gear Skylane because its sturdy and there are no wheel pants. Pilots who know how to avoid hard landings, we suspect, probably have landing gear systems that work just fine (as long as a previous owners mistakes have been properly repaired).

The next most common issues found in the SDRs were internal engine problems, including worn or stuck valves (six out of 85); cracked spinner back plates, six cases; magneto woes, such as missing teeth on the distributor gear, six cases; and carburetor trouble, including a failed inlet nipple that allowed fuel to spray inside the cowling and ignite, burning a hole in the belly aft of the firewall.

Shimmy damper problems have plagued the RG but do not stand out in the most recent SDRs. A Cessna service bulletin (80-67) was aimed at correcting the problem with a mod kit and it appears to have been successful. Also in the past, service bulletins dealt with balky throttles. Any RG should have the recommended mods installed.

Other complaints over the years have included instrument lights that flicker out, leaks around the windshield and wing root, turbos leaking oil, shearing vacuum pump drive shafts, poorly aligned aileron hinge cotter key holes, failing Bendix starters, cracked exhaust stacks and worn alternator mount bolts.

Be aware that in the past, the R/RT182 had more than its share of bugaboos. Recent history and owner comments suggest, however, that at least some of the old RG problems have been ironed out. There have been no ADs specific to the RG series in recent years. Notable old ones involve leaky flush-type fuel caps and wrinkles in the 1978 fuel bladders that trapped water. More recently, AD 2000-06-01 requires inspection of the fuel strainer assembly and, of course, AD 2005-19-11 is the infamous Lycoming crankshaft replacement directive.

Mods, Owner Group
The Cessna Pilots Association is a great source of information for all Cessna owners. A membership is $45. Visit www.cessna.org/ to sign up. AOPAs member section (www.aopa.org/) has a great summary of the hundreds of mods available for the Skylane, some of which can be applied to the RG series, including kits for drag reduction, STOL performance, replacement tanks and caps for the 1978 bladders and caps and backup vacuum and electrical systems. Well respected speed mods come from Horton STOLcraft in Wellington, Kansas (620-326-2241) and Knots 2U, Ltd. of Burlington, Wisconsin (262-763-5100, www.knots2u.com/). If there are still RGs out there with the old bladders, Monarch Air and Development Inc. in Oakland, Oregon has the fix (541-459-2056, www.airsport.com/).

Owner Feedback
I bought N79MR, a 1979 TR182, in 1998 with 4500 hours. It now has 5300 hours and 450 SMOH, which included new Millennium cylinders and new three-blade prop. I owned an Archer for 10 years and was looking for speed.


Ive always favored high-wing aircraft. My choice was between a 210 and a 182 RG and I figured with the 210, I would be dragging a whole lot of expensive empty metal behind me most of the time. I would not get a normally-aspirated model in California due to the Sierras. I wanted an aircraft that would carry four adults, a full fuel load and some baggage at 150 knots-plus.

There was an elusive intermittent gear-down lock switch problem that took five annuals to correct and a sticky turbo oil check valve that spit a lot of oil on the left fuselage, wing strut and gear strut. We replaced it but I found that if the aircraft sits and is run up to only intermediate settings, the check valve will allow oil to leak back into the turbocharger and spit out the exhaust. Once you get a high-power cycle on the engine and turbo, it acts normally. The O-540 is prone to a greasy bottom but a properly installed Airwolf oil separator has helped tremendously.

I pay about $2500 for insurance. Annual this year was $6000 but $2200 was the HSI and I asked them to troubleshoot the gear-down lock light until they found the problem (a bad down-lock switch). Annuals average $2300 unless something significant has broken.

It is an ideal cross-country aircraft with a decent 1000-mile range VFR. I will cruise between 10,000 and 14,000 feet depending on terrain and winds. I plan for 150 knots at 12,500 with fuel flow of 12 GPH average. I get high oil temps at altitude despite a good baffle seal. The oil cooler is half out of the airflow in the left front cowl so it is probably not as efficient as it could be.

Ive flown it side by side with a straight-leg 182 and, at similar power settings, the RG literally walks away. The only drawback is the RG costs more for insurance and the smaller wheels give me pause for going into dirt strips. It excels at the things that are most important: safety, speed and reliability.

I own a 1978 182RG with a partner. Prior to that, I owned a 1979 Skyhawk. Our RG has turned out to be a terrific cross-country machine: stable, fast, economical and very comfortable, although the back seat can be a bit drafty in the winter.

Its a load hauler, 770 pounds usable with full fuel and a generous CG envelope. Fuel burn runs 10 to 11 GPH with a true airspeed of 150-plus knots. No surprises, maintenance-wise: Our RG actually spends less time in the shop than our friends Cirrus SR22. Our operating costs total $114.96 an hour (tach time). My Skyhawk was around $97.

We replaced the original fuel bladder, doing most of the work ourselves. Our only complaint is oil related. Its difficult to get an accurate reading from the dipstick. We can check the oil during pre-flight and it might read 6.5 quarts. After we land, it will read 7.5 quarts.

The airplane is a dream to fly. An STEC 55 autopilot coupled to a Garmin GNS430 GPS makes a nice IFR platform. Transitioning to the RG from the Skyhawk was straightforward, with more back pressure required on landing (lots of trim helps). Its easy to overshoot the airport on VFR descents with the gear and flaps up-it loves to stay airborne.

I have been the happy and proud owner of a 1979 Cessna 182 Turbo RG for two years. My wife and I chose it for the combination of cabin size, stability, comfort, ease of entry, speed, range and payload. The turbo is wonderful for IFR operations.

The turbo eliminates the carb icing issue because it keeps the induction air warm. An additional benefit is less noise. I have been told that the turbocharger acts as an additional muffler. An additional safety feature in winter operations is the power to climb on top to get out of icing.

Two doors and a wide cabin are important as we make many trips with our two golden retrievers. Many of our trips are of the 400- to 900-mile length so speed is important. Typically, we fly IFR at 8000 to 12,000 feet. TAS at 23 squared and about 13 to 13.5 GPH runs about 156 to 158 knots at 10,000 feet. At 12,000 feet at 25 inches and 2400 RPM, I see 164 knots TAS. Range is excellent, with 89 usable gallons. My TAS runs a bit higher than book, likely a reflection of the gap seals from Knots 2U.

The aircraft is extremely stable. Flying the ILS is a piece of cake. It maintains the trimmed airspeed solidly. It tracks the glideslope with 15 inches MP, 5 degrees of flaps and 105 to 110 knots IAS. The ability to drop the landing gear at 140 knots gives me greater flexibility in slowing down and getting lower if requested to do so by ATC. The first 10 degrees of flaps can go down at speeds up to 140 knots IAS.

Load-carrying capability is great with a useful load of 1170 pounds. Short field operation is easy. We routinely operate out of grass airstrips and, in a pinch, with 20 degrees of flaps, the aircraft will break ground at 45 knots. The landing gear is very durable and we dont have to worry about wheel pants getting damaged.

The Collins stack was costing a fortune to maintain and I felt it was too much of a liability for IFR so we installed a Garmin stack. The airplane came with a slaved Bendix/King HSI. I will not fly IFR without an HSI again.

One good feature is the reliability of the engine. I have spoken with many other TR182 owners whose engines have made and exceeded TBO without a top overhaul. That makes me feel better when I cross the Bay of Fundy at night. This was a major selling point when comparing to the 210, which has a lower TBO and often does not make it to TBO. Cost of operation has been reasonable and there have been no maintenance surprises and no ADs. Insurance in Canada is running about $4000 (Canadian) per year.

I recently bought into a three-person partnership in a 1978 R182. The aircraft has very few bad habits but must be carefully managed during final approach, touchdown and rollout.

Multiple gear-down checks are, of course, vital. Careful airspeed, pitch and power control on final approach are important to avoid prodigious rates of descent on the back side of the power curve or long airspeed-dissipation glides over the concrete. I try to peg 70 KIAS or slightly less over the numbers. Vigilance is required during touchdown and rollout. I think a lot of this has to do with the small high-pressure tires (50 PSI nose, 68 PSI main).

The gear adds a lot to the utility of the airplane, even in this low-speed category. We typically fly at 150 knots TAS on 12 GPH at 6000 to 8000 feet. With 75 gallons useable, range is not an issue. Load-carrying capacity is excellent.

A Garmin GPSmap 396 is a very useful augmentation to our early-1980s vintage radios (KX-155s, Loran, DME and ADF). The leaky cockpit can get pretty cold and uncomfortable at high altitude in the winter, even with the heater going full blast.

One quirk of the R182 that I think also applies to the 210 is that exhaust enters the cabin in flight unless the cabin is kept at positive pressure by opening either the heater or the outside air intake. Another contributor to this potential problem is that, with the mixture knob all the way in, the engine is running too rich. Total cost of operation should be about $120 per hour.

The Cessna Pilots Association forums have been excellent. One of the jewels I picked up is the fact that the aircraft (and other 182s also) makes a distinct howling sound flying through rain. Im glad I knew about that ahead of time!

Ive owned my normally aspirated R182 since August of 1980. It now has 3300 hours. I love this airplane! Its relatively fast (150 knots TAS), has a great useful load (about 1200 pounds) and has been cheap to keep. Annuals generally run around $1000 with insurance at $1800 annually. Fuel burn is around 11.8 GPH in cruise.

In 2001, I added 23 gallons to the existing long-range tanks with Flint Aero fuel tanks, bringing my total fuel onboard to 98 gallons. That gives me quite a range, about eight hours. I also added flap gap seals from Knots 2U, which gave me about three additional knots at cruise.

I had the airplane painted using a paint scheme from Scheme Designers and a new interior installed in 2002. The panel was upgraded in 2003 to include Garmin GNS530 and 430 GPSs, along with a Garmin GTX 330 Mode-S transponder, GMA 340 audio panel, Bendix/King KR-87 ADF, KCS-55A compass system including an HSI, KI-256 flight director system, KI-229 RMI and an STEC-55X autopilot.

I own a 1979 Cessna R182 with a partner. We are both A&P mechanics and have done all the airframe maintenance including most of the work on the annuals alongside the AI.


The engine was replaced with a factory overhauled engine in 1997. We have over 1000 hours on the engine and have had success with it except for a stuck valve at around 400 hours. It was after returning from Phoenix in 112-degree weather, so that may have been a factor.

We cruise at 2200 RPM and 22 inches or full throttle at higher altitudes for approximately 65-percent power and plan on 14 GPH for the first hour and 12.5 GPH at cruise altitude. An engine maintenance issue is the 500-hour AD on the magneto. Weve removed it and sent it to a local shop for a fresh overhaul for about $300. We also use fine wire plugs.

We have STCs for the air-oil separator and a cooling tube for the vacuum pump. We have not had a failure and the belly is always clean. We have to replace the battery about every two years. The 1980 and newer airplanes have the batteries in the tail cone, where I assume it lasts longer away from the heat of the engine.

The landing gear is easily maintained. We have replaced the hoses a couple of times. We have disassembled the powerpack a few times and have only replaced O-rings and fluids. The motor brushes have little wear. We have disassembled the main gear actuators and cleaned and inspected them. We found one of the sector gears had been installed backwards with only two gears holding the landing gear up. We replaced O-rings, reassembled and installed, per a service bulletin, safety wire to the mount bolts.

A nosegear issue is to check the lock pins for movement and replace the plastic spring with metal, per service bulletin. The early RGs had a problem with the shimmy damper mount. That should be changed to the newer configuration.

It rides much lighter on the gear than a fixed-gear 182 because of the nose-up attitude so crosswinds are trickier. It must be landed straight or it could get away from you. It climbs much faster than a fixed-gear 182. We have climbed at over 500 FPM at 10,000 feet with four people and usually at 120 knots.

The 182RG has been safe and 15 knots faster than my old fixed-gear 182 at 65-percent power.
