The optional wing locker fuel tanks are located in the forward portion of each wing locker baggage area. The mains have to be run for 60 minutes if the airplane has 20-gallon aux tanks (or 90 minutes for 30-gallon aux tanks) because excess fuel is pumped back to the mains, and if there isnt room for it, it goes overboard. Used parts- We've parted out over 350 Cessna twins, from 303 thru 441. The wing locker fuel tanks now have tear-resistant bladders and a new metal containment canister. We used a Hartwick bladder, but the customer service was somewhat lacking. Ironically, the aircrafts success in the business niche was rather short: around a decade after its introduction, the shadow of the jet age came after the Cessna 310 in its own home, in the shape of the iconic Learjet and Cessnas own Citation series. Answer: Today, a Cessna 310 typically costs anywhere between $30000 and $150000 depending on the aircrafts age, state, and fit. LH Main Tank. Classified Ad with Best Offer. In the pattern, landing flaps deployment leads to a noticeable pitch-up moment, but this can be offset by commanding gear extension at the same time as the pitch changes will cancel themselves out. Prior to installing the new tank I spent quite a bit of time cleaning the bay to remove any fuel stains and dirt. Local Pickup. Long Range. Power is provided by the Continental O-470 family of engines for most models, though not exclusively. Single-engine service ceiling went up with the turbo models, to 17,200 feet in the T310R; a 310B could hold 7,700 feet on one engine. Cessna didn't stop there. So, Cessna provided continuous-duty fuel pumps that move fuel from the front to the back of the tank. Reliance AeroProducts International is a FAA Certified Repair Station and provider of fuel cell repairs and re-certifications. Whether the difference is worth it depends on the desired operational profile, which stands true today where the difference in used prices has kept the same proportions. According to owners and mechanics, the 470s live a long and happy life under 310 cowls, and the number of service difficulty reports slated for the 470-powered airplanes is proportionally lower than for the IO-520 and TSIO-520 versions. Whether these make it hard to deal with depends on your point of view. The first step is to know which bladder your aircraft uses.

Next time, Ill polish the outside surface of each tube with a scouring pad and lube the tube with a little light oil to lessen friction. Due to a spate of less-than-stellar logbook maintenance records that referred to the shop work order numbers in lieu of actually describing the work done, I wasnt able to accurately determine the age or type of the installed bladders. In the meantime, Jamie passes all of his knowledge about flying, planes, and flight simulators on to the readers at Aviator Insider. The 310 offers more payload and cabin room than its competitors, and is more stable in turbulence, but at the cost of a heavier control feel than a baron. The keys to getting great bladder service life start with the installation. 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. Average normally aspirated 310s run from $40000 for the earliest models up to $191000 for the newest 310R. Put your ear down by the filler cap and open it. Since I was installing a new bladder I cut one side of each nipple on the old bladder and shot a little bit of LPS-1 into the cut; that helped release the tubing. Flaps were of the split type for aerodynamic efficiency (no external flap brackets), and the gear was of electromechanical design. Yes, we're talking tuna tanks, those slightly clunky vessels at the ends of the wings, slated to hold 50 gallons of fuel each. 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. Most shops either stock or can order whatever you require to keep it running within short notice. However, the turbos are relatively small, and power is down to 55 percent by 25,000 feet at the maximum recommended cruise rpm of 2,350. The most recent type-specific AD, 90-02-13, covers the main landing gear barrel inner bearings. Finally, the auxiliary tanks were enlarged once more, in 1973, to 63 gallons total. Still, the 310 is large and heavy enough that braking performance can be marginal. When we're not in the air, we're here helping others how to join us here at Aviator Insider. Owner CommentsI have owned three turbocharged Cessna 310s. It starts with nomenclature. Baggage capacity grew according to the aircrafts capabilities, going from 200 lbs to 600 lbs. The optional auxiliary tanks are available in two sizes. Even without radar, some 310s with full fuel push the forward CG limit with just a pilot in front, so there are times when seating has to be assigned. 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. Pitch response is heaviest, roll the lightest, with generally good stick force per G and longitudinal stability. The excess is pumped back to the mains and overboard if there isnt room. To support buyers I offer a 310 information package [Ed. At the time of our last look at the 310 in 1996, the FAA was considering a stiff update to the AD that thankfully did not come to pass.

He ran the mains dry. At maximum gross weight, earlier variants could still climb at 415 fpm. 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. Use a very sharp pick to scratch the debris out of the screw head. 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.

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. If I had the $$, I'd convert mine to a Colemill. The IO-470s used on earlier airplanes are much less likely to develop cracks. Removing and replacing a bladder is not a difficult process. Parts availability has never been a problem. Installation of the tank was pretty easy. An AOPA analysis of 225 service difficulty reports (SDRs) from a sample of 150 units from different Model 310 families showed that 40 of these were related to the landing gear. When fuel starvation shuts down an engine, the silence is mighty loud. Maximum boost for a sea-level takeoff is a moderate 32 inches.

Costs have been going up, but that speaks more of trends in general aviation economics. Theoretically, its physically and materially possible to field repair a bladder given enough time, diligence and discipline. To improve low-speed handling and stall behavior, the company MicroAero offers vortex generators that are attached to the wings and vertical stabilizers. The aircraft was framed as a purpose-built tool for businessmen to grow and as a long-term alternative to the surplus conversions that had flooded the niche until then. On approach, some power has to be carried. Each of the latter can accommodate two sets of golf clubs. So if you have a right-side locker, you will have to draw down the right main by at least 20 gallons to make room for the locker fuel and then crossfeed the left engine to minimize lateral imbalance from those extra 120 pounds now out on the right wing tip. This 310, with canted tanks, swept fin and short nose, is one of the most attractive light twins ever built. I did have some difficulty loosening the nipples connecting the tank to the fuel outlet and the fuel cell vent. AOPAs Air Safety Foundation further subdivides accidents and incidents into pilot-caused and machine-caused accidents. Cessna didnt stop there. The pilot must remember to fly about 1 hour of fuel out of the mains before switching to aux.
