Plenty of Model 310 units in the market have undergone a much-needed avionics rework over the years, but it is still possible to run into original spec aircraft, which means a somewhat steep price to bring them to modern standards. The shortcomings of the Apache were partially addressed with the Aztec series, but in 1963 it passed the torch onto the more powerful and maneuverable Twin Comanche. This variant also swapped the engines family from the O-470 to the fuel injected version of the Continental O-520 line, producing 285 hp each. Another scenario goes like thisPilot: Top off the mains, please. . 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.

(Such nicknames come from the tank's fish-like profile.) During repair new nipples are installed and repaired tanks are guaranteed for two years. The 310 makes for a good, stable IFR platform, according to owners, with excellent cruise stability. 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. Might as well do both right away! Cessna part 1200065-5 $1,485.00 SKU: EA-1200065-5E Add Installation Kit For This Fuel Cell: The pilot can read the tanks not being used by toggling a switch. This is primarily because of the exhaust thrust augmenter tubes positioning. The fuel vent valve must be reinstalled with the hinge line up. Among the more noteworthy ones are the Riley Rocket 310 and Riley Turbostream 310, by aeronautical engineer Jack Riley. Much like the parts supply, finding technicians with experience in this aircraft is very common thanks to the sheer number of units delivered and still airworthy. Much of it consists of Cessna Dealer Sales Manual material originally penned by him, with some additional supporting articles. McCloskey said that some installers tape a pad onto the end of a broomstick or dowel and use it to push the bladder into position in the corners of the tank bay.

I knew that I would be replacing the engines, and decided that the spoilers would help assure making it to TBO. The aux tanks feed directly to the engines, so the only pump that serves these tanks is the engine-driven one. This coupled with the natural rolling tendencies caused by the tip-mounted fuel tanks, can make for a busy few moments immediately following engine failure. The fact that theres a lot of fuel hanging out on the wingtips tends to exacerbate the side loads on the gear, as well. Replaces Cessna 1200065-5 Home Cessna Models 182 Models Fuel Cells / Bladders S/N 18253599 & Up Fuel Cell. 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.

The 310 competed more directly against the Twin Commander 520 (discontinued that same year) and Beech Twin Bonanza, which was dropped a few years later in favor of the Travel Air and 55 Baron. Using a fuel level dipstick will lessen the possibility of ever hearing that silence. In the past three years I have focused on 310s and 340s, generally listing six to eight 310s and selling two or three a month. Still, the 310 is large and heavy enough that braking performance can be marginal. The next significant change was in 1962, with the 310G. Many were retrofitted with the later, and better, Clevelands. When we're not in the air, we're here helping others how to join us here at Aviator Insider.

C-310s with lots of avionics and other options compound the loading exercise. Seeing a gap in the market wide open, Cessna Aircraft Company, at the time led by Dwane L. Wallace, made its move with the Cessna 310. Later model 310s have heavier main gear torque tubes and side brace support brackets. I have been taught by 310 drivers with much more experience to set the nose down lightly and avoid high-speed turns that induce side loads on the gear components.

When vents are blocked its not unusual for the floor of the bladder to be pulled up. Most airplanes have just one of these, and its contents cannot be consumed directly by the engines. 91 or F.A.R 135. Robertson Performance Systems (800 430-1585) provides a vortex generator kit which not only decreases the Vmc by 10 knots but it also increases the zero-fuel weight by 385 pounds and the gross takeoff weight by 185 pounds. The optional auxiliary tanks are available in two sizes. This, of course, must be balanced against the extra hazard posed by single-engine operations when low and slow.

Climb, speed, and range performance on the 58 Baron was on par with the 310s. They use a cartridge design and can be easily serviced, unlike factory ports that must be completely removed. 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. 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. Construction - Extra grade fabric used most times best suited for Jet A.

A fuel flow gauge, fuel quantity gauge, and a fuel low level warning light are located in the cockpit. As for advice, I strongly recommend membership in the Twin Cessna Flyer organization. The Eagle website contains a long list of hints to make installation and removal easier, and I can tell you that making the bladder more flexible by heating it is a help. Flying an aircraft with a weakened bladder negates this safety feature. the amount of weight you can put in the cabin; it has nothing to do with total load.

A long-range airplane has six tanks and 10 fuel pumps. Though the PA-23 would later be a direct competitor to the 310, the original Apache was far down the scale on power. Pilots report that real-world operations arent as good as these numbers would have you believe. Their investigation suggest the seepage is from the top of the bladder.
