cessna 310 fuel bladders

The aux tanks feed directly to the engines, so the only pump that serves these tanks is the engine-driven one. The fuel burn isn't much different than 470's to the 550's since whatever fuel gallons extra you burn, you usually are flying faster to make up the difference if we compared MPG. This is the perfect time to make up a fuel tank quantity dipstick (I know I sound like a dipstick salesman, but they work and they are a simple safety tool) and to make sure you know exactly how much fuel your new bladder holds. Early models had Goodyears, which caused some problems. Flap deployment speeds were gradually raised, starting at 140 knots until the Model 310K increased it to 155, while the 310R could drop them at 160 knots. In general terms, the 310's a sweetheart, a veritable immovable object on instruments and a good, if somewhat stiff, rider in turbulence. The airplane is powered by two horizontally opposed, six cylinder, direct drive, normally aspirated, air cooled, fuel injected engines. Depending on the option fitted, this could expand the aircraft's capacity from 102 gallons up to 207 in total. Still, for a twin-engine aircraft, the Cessna 310 performs reasonably with only one running. 1959 saw the first big change in the 310, with the switch to fuel-injected 260 HP Continental IO-470D engines and another rise in gross weight This airplane was dubbed the 310C. But there are things to be careful of when considering a 310. Much of it consists of Cessna Dealer Sales Manual material originally penned by him, with some additional supporting articles. Annuals have averaged $1500-2000, which may seem low-but not unrealistic if you look for an airplane that has been flown and maintained in a consistent manner. With the stretched cabin of the 1963 310H, more baggage space was opened up. Payload with full fuel varies depending upon the model, equipment and fuel tank arrangement. Payload in a lightly equipped 310C with auxiliary tanks might exceed 700 pounds, while it could be as low as 400 pounds in a 310R. Flaps were of the split type for aerodynamic efficiency (no external flap brackets), and the gear was of electromechanical design. Usable fuel capacity can be 100, 132, 142, 182 or 203 gallons-from 600 to 1218 pounds of fuel. Three-ten shoppers (and pilots) would do well to sit down with a jug of coffee and a good reading lamp and bone up on this airplane's fuel system. Overall, a good package of background information.]. A T310R, for example, has a zero fuel weight of 5015 pounds. Presumably, the canted tanks were to improve lateral stability by imparting additional wing dihedral. The speed vane housing the Hobbs meter on the bottom of the right wing is a small tab that is compressed by airflow, but due to its diminutive size and sleek profile, and many owners have accidentally snagged it into inoperability. You could say that it has substantial roll inertia. When the Cessna 310 was first introduced in 1954, the aviation industry was immersed in the aftermath of two major wars. In my opinion, the 310 is the ideal light twin, with reasonable single engine performance, safety, looks, comfort, and range. This, of course, must be balanced against the extra hazard posed by single-engine operations when low and slow. Cessna SKYMASTER 336 1964; Cessna SKYMASTER 337H; Cessna 310K; Cessna 337 Skymaster; Cessna 150 1968; Cessna 150 1969; Cessna 150 1974; Stalls on the Cessna 310 are not described as particularly nasty but are still not quite as gentle as on Cessnas high-wing singles. RAP is a proud certified repair center for the following: RAP supports all branches of the United States Military through the repair of aircraft fuel cells / fuel bladders. Greaser! Learn more about Mailchimp's privacy practices here. Engine-out performance is better than average, with normally aspirated single-engine rate of climb pegged at anywhere from 330 to 380 FPM, depending on model. I was pleased to observe about 8 to 10 knots increased speed at comparable power settings, a greater rate of climb, and stabilized oil consumption of about 1 quart per 20 hours. Alternator Failure (Dual) Flight Instruments. I find that burning about 20 gal. Ells is the owner of Ells Aviation and lives in Paso Robles, Calif. with his wife Audrey. The cabin on the Cessna 310 traditionally seats four passengers plus one pilot, however starting with the Model 310G, a factory option for six passengers was added. // ]]>, Twin Cessna Articulating Crew Seat Pivot Arm, Our inventory of almost 100,000 part numbers of new surplus Cessna parts includes. Answer: With a cruise speed of 183 knots at 7500 ft, the Cessna 310 burns around 25 gph. setTimeout(function(){document.getElementById("CountryId").dispatchEvent(new Event("change"));},50); A choice of IO-520 or Voyager IO-550s is offered. Copyright 2023 Aviator Insider | A Topsail Media Company | Powered by Astra WordPress Theme. Not only did the 310 start out a strapping young twin, but it lived a long and fruitful life, finally surrendering to old age and declining market share in 1981. All rights reserved. Removing and replacing a bladder is not a difficult process. That hot, dry climate went a long way in allaying my concerns about corrosion in the airframe. The registration records showed that 7LJ had been based in Albuquerque, N.M. for at least 20 years. The most recent type-specific AD, 90-02-13, covers the main landing gear barrel inner bearings. Micro Aerodynamics makes a kit, and also offers nacelle strakes that reportedly improve stall behavior. Out of 225 SDRs (for about 150 different airplanes), we counted more than 40 regarding the gear alone. The result is an Belvoir Media Group, LLC. Finally, the auxiliary tanks were enlarged once more, in 1973, to 63 gallons total. You can guess the rest. The attitude that its just another airplane can cost the buyer dearly. With so much to choose from, any serious buyer should be able to find an airplane that fits the bill. Whether these make it hard to deal with depends on your point of view. According to information on both Eagles and FFCs websites, only the US-943 is a candidate for repair. And although the system worked, exhaust gases, being quite corrosive, wreaked havoc on the wing structure. } Maladies include broken or cracked mounts, support structures, actuator rods, door hinges and actuators, shock struts, and bellcranks. Starting with pressure-carbureted 240-hp O-470 Continentals, the 310 gained real fuel injection and an additional 20 hp per side with the C model, in 1959. Also available are engine and prop upgrades from Colemill Enterprises for the 310F through Q, which carry with them gross weight increases. It can be a way to cut back on labor costs if an owner/pilot is comfortable in their technical abilities and savvy about working on one of the most important systems on their Cessna. A new bladder should provide good service for at least 20 years and much longer if you take steps to keep the top surface of the bladder cool. Other loading and operating considerations were introduced in the later models. With a little experience you learn to stay light on the ailerons and ride both rudder pedals in turbulence to smooth any untoward tendencies. Remember, also, that the cost of maintaining an airplane like the 310 is keyed more to its health and the price of parts than the purchase price. I strongly recommend the turbocharged models. The twin-engine aircraft was fitted with engine exhaust thrust augmenter tubes, and on top of using its now-characteristic tip tanks, the early models stored all fuel in them. Before choosing the option to send out for repair or install new, the leaking bladder must be inspected to determine the best course of action. Despite its recent appreciation, I believe the 310 remains one of the best values on the used aircraft market. Along with that, weight and balance has to be watched more closely. And the 310 needed help in this department, what with 300 pounds of avgas way out there on the wing. Flipping the bladder to expose the top and bottom surfaces while its spread out in sunlight on the top of the wing is an easy, safe, no-costand greenheating method. We stock parts for all Cessna Multi-engine airplanes: Copyright 2023 Preferred Airparts. I have avoided the two big 310 bugaboos: gear problems and exhaust-related corrosion. If time is critical, providers offer repaired bladders on an exchange basis. Among the more noteworthy ones are the Riley Rocket 310 and Riley Turbostream 310, by aeronautical engineer Jack Riley. The airplane can also be a handful to fly, though pilots note that with proper training and due diligence, it can make a good IFR platform. Unlike many airplanes with long production runs, the 310 went through steady refinement over the years, with a slew of designation letters following the model number. More weight in later models about makes up for the extra power: A 260-hp-a-side Q model turns in 186 knots (71 percent at 7,500 feet, on 26.5 gph) and climbs at 1,495 fpm; not bad considering the Q's 600-pound higher maximum gross weight. Baggage capacity grew according to the aircrafts capabilities, going from 200 lbs to 600 lbs. Cleveland offers brake sets that can be retrofitted in lieu of the original Goodyear ones, which are more expensive to maintain on the long run. At that point the mains may or may not be full, depending on whether the aux tanks have been used and whether the transfer was done with room to spare in the mains. In the single-engine category, the 310 also performs reasonably well, however few light twins are truly spectacular with one engine inoperative. Money talks, though, and the true cost of a twin is doubled engine maintenance and fuel bills. This section of the article is only available for our members. We noted several cases of full or partial gear collapse thanks to parts failures. I have an Insight Gemini 1200 Graphic Engine Monitor, and the cylinder head temperatures never exceed 350 degrees on the hottest day, leanest mixture, and highest settings used. For the baseline model, the aircraft has a length of 27 ft, with a wingspan of 35 ft and a height of 10 ft 6 in with the landing gear extended. Collapsed fuel bladders have caused many incidents and a few accidents due to restricted fuel flow or to fuel exhaustion because a partially collapsed tank appears from the filler opening and on the gauge to be full of fuel, but in reality contains much less. Certain traits on the Model 310 can catch an inexperienced pilot off-guard in case of single engine failure during take-off or landing. The gear has a number of critical components that must be attended to and properly rigged during annual inspections. Something went wrong. Other recent and notable ADs include: 98-1-8, replacement of two-piece carb venturis with one-piece units; 97-26-17, ultrasonic inspection of the crankshafts with possible replacement; 96-12-22, repetitive inspections of the engine oil filter adapters; and 96-20-7, repetitive inspection of the combustion tubes on the Janitrol cabin heater.

If an owner came to me asking me to help him repair a bladder tank or approve a field repair of a bladder tank Id say no because I dont believe the parts are available nor is the data sufficient to ensure a safe field repair. Because the gear makes the airplane sit up high, new pilots are cautioned to be careful of hard landings. The aircraft is certified in the normal category, which means intentional spins and aerobatics are not permitted. I flight plan for 175 knots and firmly believe in the highest recommended manifold pressure and lowest recommended RPM settings for the desired percentage of power. The single-engine ceiling, however, grew considerably in the turbocharged versions. An additional cabin window was introduced with the Model 310F. Unless otherwise noted, these reviews carry product pricing from the time of the original review. Then the rubber of each nipple can be softened by wrapping it in a towel or rag thats been dipped in hot water. By the 310I, cubic feet available certainly began to exceed the lifting and weight-and-balance capacity of the airplane. Most shops either stock or can order whatever you require to keep it running within short notice. While Cessna president Dwane Wallace built an aircraft for the business flier, the actual demographic taking the Model 310 to the skies today has changed a lot since then. item 1 Goodyear Beechcraft Baron 55 RH INBD Fuel Cell Bladder PN 002-920034-2RH, item 2 TWIN CESSNA 414 AIRCRAFT RIGHT INBOARD FUEL CELL BLADDER 2F1-6-33180-10RH, item 3 UniRoyal, Beechcraft King Air C90, C90A, C90GT, E90 RH Fuel Cell PN 100-381002-2, item 4 Beechcraft King Air, Uniroyal RH Fuel Cell Bladder PN 50-389034-8, 4.6 out of 5 stars based on 8 product ratings, 4.8 out of 5 stars based on 6 product ratings, 5.0 out of 5 stars based on 2 product ratings.

Last year my factory gold medallion remans were about 50 hours past TBO when the latest McCauley prop AD for this model left me with no realistic choice but to replace both props. Long Range. Might as well do both right away! The normally aspirated models are happiest in the low teens, while the turbos have service ceilings in the mid-20s. A proper check during the pre-buy is sufficient for prospective buyers to avoid surprises, while current owners should keep close attention during inspections and do preventive work whenever issues are found. The 310 is an all metal, four/six-place, low wing, twin engine airplane and is equipped with retractable tricycle landing gear. Many used parts are not listed on our web site partssearch, so please contact us to check stock. The Hartzell three-blade propellers have also been commonly installed in regular Cessna 310 units without further engine modifications. Paul pointed out a major advantage of Eagle's STC'd fuel drains/test ports. Jamie comes from a long line of military and civilian pilots! The airplane can cover roughly 500 NM in still air with max payload. The wing area is of 175 sq ft. For pilots who do not meet this experience threshold, the number goes up from $4980 to $7400. I knew that I would be replacing the engines, and decided that the spoilers would help assure making it to TBO. For those readers who are old enough to want to avoid thinking about it, the 310 should look familiar: it was the costar of televisions Sky King adventure series. Jamie's partner also works in aviation as a mechanical engineer. It starts with nomenclature. Cessna Models - 205 / 206 / 207 Models - Fuel Cell/Bladder - Knots 2U, Ltd.

The props are subject to a couple of ADs: these include the infamous McCauley prop inspection AD (95-24-05) and 94-17-3, repetitive inspection of the prop hub grease fittings. Combined with the relative fragility of the gear, these can be a real problem. After removing the screws holding the filler neck plate in place and setting it aside, I worked through the access hole to remove the fuel tank air vent valve. If you need to get above weather or take advantage of winds at altitude, this plane still climbs well at 18- to 20000 feet, while the normally aspirated 310 runs out of steam at about 10- to 12000. The engines on many 310s are Continental 520s, which have a well-known propensity for case cracking. The Apache was a commercial success as a trainer thanks to its docile handling and forgiving flight characteristics, but in the niche of business aviation, its engines stopped it from ever truly competing with only 150 hp per engine, the aircrafts top speed was a measly 157 knots, and its range was capped at 603 nautical miles. Steve Ells has been an A&P/IA for 39 years and is a commercial pilot with instrument and multi-engine ratings. All of the major bladder repair companies offer a test and advise option that clarifies the repair/new decision. 1976 Cessna 182P in very good condition located in Southern California presently at KAJO Corona, CA Airport. He ran the mains dry. Designed to shear off in the event of a crash, the tips were the only tanks until the 1958 B model. The two largest clubs that cater for just about all Cessna models are the Cessna Owner Association and the Cessna Flyer Association. Of course I dont push the engines to the maximum, and find that I can cruise at 25.5 to 26 inches, 2200 RPM, with a fuel flow at altitudes in the low teens of about 13.5 to 14 GPH and still keep the EGTs below 1520 degrees. These tanks are bladder-type cells which supplement the main tank fuel quantity. All parts are stored in modern warehousing, to preserve their quality. We're absolutely loaded! Distinguishing marks of these early models are multiple rear windows, a straight tail, and tuna tanks, so-called for their shape. Also the landing gear must be adjusted carefully and properly to insure smooth and dependable operation.The 310s fuel system has been unfairly criticized in the past. It is a challenge to grease the landings, but I make every effort to protect that long, spindly gear. At the other end of the airplane, the 310 nose grew, Pinocchio-like, through the decades, making a big leap with the 1975 R model. A Model 310B tops off at 7700 ft, whereas a Model T310R can reach a whopping 17200 ft with an engine feathered. Figuring a maximum ramp weight of 5534 pounds, 519 pounds of fuel can be put in the main tanks. Initially, the two major civilian twin-engine general aviation offers on the market were the Beechcraft Twin Bonanza and the Piper Apache. This has kept prices down over time. The airplane handles big and is a stable IFR platform. if(document.URL.indexOf("/register") > -1){ About every six hours I am on my back under the airplane cleaning the areas in the line of fire aft of the exhaust augmentors. Removal and replacement labor usually runs between 10 and 12 hours. The same caveat applies-there has to be room enough for the fuel, so the pilot waits until theres 180 pounds or less in the mains before transferring fuel from the locker tanks. The dawn of the jet age, fully realized during the Korean War, had signaled a major shift in the American militarys design requirements and procurement decisions. To improve low-speed handling and stall behavior, the company MicroAero offers vortex generators that are attached to the wings and vertical stabilizers. The Cessna 310 is an American four-to-six-seat, low-wing, twin-engine monoplane produced by Cessna between 1954 and 1980. . This means that using fuel from either the auxiliary tank on the same side, or the main tank on the opposite side, about half the fuel flow will be moving to the same-side main. Piper's Apache had come onto the scene about a year earlier, but with only 150 horsepower a side. At maximum gross weight, earlier variants could still climb at 415 fpm. That's actually a bit amazing, considering the overall age of the fleet and the complexity of the machines. The tip tanks became twin Cessna hallmark. UPJR740L). Cessna was moving aggressively into the business market, and the 310 was a key part, and first element, of that plan. The 310R was the final development of the airplane, and stayed in production until the line was closed down in 1981. A 310 might not be the most expensive (yet) or high-tech airplane you can own, but in my mind flying one is like cruising in one of Detroits vintage big-block V8s: Shes easy to repair, sounds mean, goes fast, and flat-out looks good. Produced until 1980 and still extremely popular today, the features that made it a great business aircraft in 1954 also upheld it in the leisure side of general aviation.

Another aspect of the gear that deserves mention is the brakes. I also had to remove the tank sump quick drain fittings and the fuel quantity transmitter and float. Also using spoilers to produce a drop in airspeed to permit landing gear operation is a nice option to have when too high or hot for normal gradual speed reductions or while descending. This combination permits me to leave the power at 55% (my typical cruise setting) and still descend at 700 to 1000 fpm without exceeding 155 knots. Fuel flows at the rate of eight gallons per hour. The reputation for Dutch roll and yaw problems is, in my opinion, undeserved. the amount of weight you can put in the cabin; it has nothing to do with total load. If this is done properly, trouble can be avoided, but failure to treat the gear right increases the odds of failure dramatically. Turbo single-engine performance is even more impressive: from 390 to 440 FPM-thats up in turboprop territory, and very impressive for a piston twin. Dont fly again until the blockage is opened. Aero Tech does custom work for ferry tanks, off-road vehicles and marine applications. This involved replacing the Continental IO-470 engines with the turbocharged intercooled Lycoming TIO-540, with an output of 350 hp.

Lineperson: Yes, sir, whereupon the auxiliaries get filled to the brim. A fuel flow gauge, fuel quantity gauge, and a fuel low level warning light are located in the cockpit. For some reason, Cessna decided to designate the tip tanks as the mains, and the wing tanks as the auxiliaries. The twin rearview windows were removed from the 1965 Cessna 310K onwards in favor of a large single one to improve visibility. An optional large baggage door was introduced on the 310P. In the event of a fuel pump or engine failure, the aux tank on that side becomes uselessno crossfeed from the aux tanks, and no transfer is possible. Using a fuel level dipstick will lessen the possibility of ever hearing that silence. General opinion of the IO-470 has always been good, and it seems the model has performed quite well in the 310. Its not unusual for the actual fuel capacity of a bladder and the capacity written in the owners manual or the aircraft flight manual (AFM) to differ. Compare this to the Beech light twins, which began with 180-hp Lycomings in the Travel Air and culminated (imploded, some say) with a pair of turbocharged 380-hp monsters in the 56TC.
