Pressurization can be problematic, as well. The updated Chancellor abolished the original tip tanks in favor of a longer wet wing, benefitted from a lengthened fuselage, mounted an improved 5.0 psi pressurization system, and enjoyed a 400-pound heavier gross weight. The 414 first flew in 1968 and was certified in 1969. In 1981, the price difference between the two models was significant, though performance didn’t seem so dramatically divergent. At reduced fuel levels, I’ve transported six in comfort in a 414. The cabin pressurization controller enters high altitude mode when the airplane is landing into or departing from airports with an elevation between 8000 feet and 14,000 feet MSL. The prototype, registered N7170C, first flew on 1 November 1968 and production aircraft were available in a number of optional seating arrangements and avionics packages. In the early ‘80s, Piper, Cessna, Beech Commander, and Aerostar were producing a dozen different models of dedicated executive transports. Built by Cessna, the Cessna 414 is an American light, pressurized, twin-engine transport aircraft. The pressurized 414 was developed to appeal to owners of un-pressurized twin-engined aircraft and was based on the fuselage of the Cessna 421 and used the wing design of the Cessna 401. Additionally, the airplane takes turbulence well, with a high wing loading of nearly 30 pounds/square foot. “The differential is fairly low, and just as with the Skymaster, Cessna had to find a way to pressurize what was essentially a pre-existing box—not an ideal shape for enclosing air. If you do it right, you won’t even know it’s there. Learn About Bill's Book Here, Designed by Elegant Themes | Powered by WordPress. In other systems, the WOW switch may directly control the safety valve or a pneumatic source valve that causes the safety valve to be held open until the source is cut at takeoff when the WOW switch opens. heating. He has authored more than 2,200 magazine articles and was the on-camera host of the 1980s TV series “ ABC’s Wide World of Flying.” Bill is currently rated Commercial/Multi/Instrument/Seaplane/Glider/Helicopter. The Cabin pressure control system regulates the escape of air though the use of two pneumatically driven outflow valves; the primary outflow valve and secondary outflow valve’s are similar except for a pair of electric solenoids (climb, dive) and an ejector package which is included only on the primary outflow valve, in addition the primary outflow valve is larger in diameter. The system may begin to leak after a few years, partially nullifying the whole reason for buying an inflatable airplane in the first place. The 414A is equipped with two Continental TSIO-520-N engines producing 310 hp per side, burning about 17 gph each at 75% power. Common are engine and aerodynamic modifications, including winglets. Most of the time, you simply set it and forget it. Pressurization is a totally transparent system when it’s working properly. The 414 may be a tad slower than the 421, but it’s also less expensive to buy and operate, easier to fly, and it’s one of those airplanes that hardly anyone dislikes. Buy Cessna 414A servicing tools and accessories today from Tronair. It is powered by two wing-mounted 310 hp (231 kW) Continental TSIO-520-J horizontally-opposed six cylinder engines. With the strong pressurization system cranked up to max, there’s not much reason to level lower than about 16,500/17,500 if you prefer VFR or FL180/FL200 if you’re filed IFR. Cabin Pressurization Venturi - Right. Like most other Cessna piston products, the 414 Chancellor was discontinued in the mid-‘80s after some 1100 had been sold, and many of those are still active. Yes, I know – if you have to ask how much…? Just as the aircraft's Of course, that’s just the price of admission, and any intelligent twin buyer should be careful to consider upkeep and normal operating costs. The pressurized 414 was developed to appeal to owners of un-pressurized twin-engined aircraft and was based on the fuselage of the Cessna 421 and used the wing design of the Cessna 401. T: +421 910 33 33 11. [1], In 1974, American Jet Industries built a turboprop-powered conversion of the Cessna 414, named the Turbo Star Pressurized 414, using Allison 250-B17B engines. It’s also 51 inches high—not nearly tall enough for stand-up headroom, but big enough to allow easy walk-around space inside the cabin. Place an order for ground support equipment from Tronair now. The door seal needs to be replaced about every 10 years or 2000 hours. When there is a problem, it can usually be found in a sticky outlet valve or cabin leaks. Cessna 414 Series Aircraft Information. Pressurization Dump Valve. Chancellors can be made timeless, however, with indefinite lives extended by new engines, improved avionics, and modernized components. Exhaust systems are always a concern on the older TSIO-520 Continentals, and turbochargers can also demand major attention (read EXPENSIVE). Engineers responded with a proposal for the Model 414, an airplane that could be built from proven, virtually off-the-shelf assemblies. The 414 has the capacity for 1-2 crew members and up to 8 passengers. In the early ‘80s, Piper, Cessna, Beech Commander, and Aerostar were producing a dozen different models of dedicated executive transports.
