The early Cheyennes were later refined with some aerodynamic improvements, but the PT6-28s produced only 10 to 15 percent faster cruise speed than their piston siblings and at a much higher fuel consumption. This line of thinking has prompted another round of endless cerebration. 2023 Aircraft Owners and Pilots Association, Max Operating Speed see POH for speeds above listed altitudes. In ground handling and during cross-wind operations it is especially troublesome, since it fights the desired control inputs. 820 degrees C and it is necessary to have fingers poised over the fuel of the Cheyenne series, and Piper. The Cheyenne became the Cheyenne II. Our problem is that the right engine from day one has periodically and suddenly lost two or three quarts of oil. No surprises there. Wing-tip fuel tanks were standard with this airplane, and so were redesigned engine air intakes and elongated exhaust stacks. It is powered by PT6A-135s rated at the same 620 SHP as the Cheyenne II but features a stretched fuselage. The Navajo airframe was fitted out with 620-shaft-horsepower Pratt & Whitney PT6A-28 engines, given a pair of 30 gallon wing-tip fuel tanks, and certified in May 1972.

Remote mounted avionics were considered mandatory in turbine powered airplanes. For both individual and corporate owners, the early Cheyennes make sense as step-up purchases, as long as the combination of low price, low maintenance, and high-performance remains in vogue. This seems like a time for study, contemplation, analysis and thoughtful decision-making. It was completed in November. In ground handling and during cross-wind operations it is especially troublesome, since it fights the desired control inputs. A number of pilots have commented on the pitch sensitivity of the original Cheyenne during maximum power climb, with cg toward the aft limit and in approach mode. PIPER Cheyenne 400 | SKYbrary Aviation Safety Why is the hourly cost so high when only burning 60gph? Many of the systems are not as well designed and organized as in later airplanes and because of the affects of age (not to mention abuse and neglect). had the aircraft off the runway and heading up at an amazing rate of climb. Weight and balance takes some careful managing. On the whole, we are pleased with it. It sprouted the now-typical wing tip fuel tanks, PT6A-28 engines flat rated to 620 SHP and a redesigned flight control system that included a stability augmentation system (SAS) that became an item of major controversy and a blot on the reputation of the entire series. Price: USD $1,300,000. Then, in 1984, the Cheyenne 400LS was born the queen of the Piper Aircraft fleet. In Kellys words: None of these planes should be running around without this modification.). So I wrestle daily with these calculations and estimations. The aircraft Piper management was slow to accept the turboprop engine; some members of the Piper family were said to be set against it. Also With This Article Click here to view charts for Resale Values, Payload Compared and Prices Compared.

Pratt & Whitney of Canada PT6 engines power all but the 400LS, which uses Garrett (now Allied Signal Engines) TPE-331s. Careless operation has the obvious consequences. The confusion started when Piper introduced a lower powered, lower cost turboprop and called it the Cheyenne I (PA-31T1). more and further and does it all for about half the cost of a comparable The problem is this: At the top of a phugoid cycle, the angle of attack is high, and the SAS pulls forward on the yoke. The majority of the Cheyenne 400LS aircraft were fitted with nine seats, including a potty seat that can be completely enclosed by an accordion door neatly hidden in its furniture cabinet. 0000012075 00000 n Although becoming an Earth-rounder has been postponed by the COVID-19 crisis, we are looking forward to completing the mission in a post-pandemic world. turned on and the starter button is pressed. There is no SAS or other device required on the I/IA or IIXL. Engine gauges are monitored for safety. I remember reading a Richard Collins column years ago in which he described the number of yellow legal pads he used up while deciding on the Cessna P210 he ultimately bought and flew for 8,000 hours. This is because there are more systems, including the SAS. When you think about it, how can I justify taking the chance of just overhauling our own engines? Believe it or not, it felt good; I felt I was being a good steward of the airplane. For a pilot with no turbine experience, the I or IA would be the best choice because it is the least demanding to operate. For a large number of buyers, the early models of Pipers Cheyenne series fulfill these requirements. But take a high-performance turboprop twin at a bargain-basement price, add a macho pilot with limited experience and training, then toss in an engine failure, IFR weather, or any kind of distraction. Piper Cheyenne 400LS - Centurion Jets - Private Jet Company AM With its powerful Garrett TPE 331-14-801 turboprop powerplants and capable systems, Piper's Cheyenne 400LS operates quite comfortably at altitudes as high as 41,000 feet while achieving impressive speeds Written by Twin and Turbine Magazine [3], Flat rated to ISA+37, the turboprops maintain their power to almost 20,000ft (6,100m).

Full power is set for takeoff and can be maintained all the way up to altitude and cruise. Accidents The two most notorious Cheyenne accidents were original PA-31Ts involving longitudinal control-the much maligned SAS system. The first production Cheyenne III flew for the first time on May 18, 1979, and FAA certification was granted in early 1980. Aircraft Location: Stockton, California. executive turbine fraternity. Visibility from the cockpit is a real shortcoming until the 1980 model year. An angle of attack sensor on the right side of the nose measures and transmits angle of attack to a simple computer which commands a servo to vary downspring tension. The start sequence is fully automated. These are the PA-31T series, or Cheyenne/II, Cheyenne I/IA and Cheyenne IIXL (plus an unpressurized hybrid developed for the air taxi and commuter markets, the PA-31T3 or T-1040) and the PA-42 series, which consists of the T-tailed and longer-fuselage Cheyenne III/IIIA and Cheyenne IV/400LS.

Learn how your comment data is processed. 0000043652 00000 n There is one accident that occurred to a PA-31T under similar circumstances to the two that called the SAS into question: loss of control during an instrument departure in fog. Generally speaking, operators of the original version should make a dedicated commitment to good initial and recurrent training, rigorous pre-purchase inspection and evaluation and make sure they find a very qualified maintenance technician and shop. Structurally, they have weathered well over the years. [3], The aircraft's top speed is 351kn (650km/h; 404mph) and was faster than the Citation I on most trips while burning one-third less fuel. Torque limiters protect the engines from injudicious applications of power Some changes, such as a retrofit that reduces temperatures during engine start-named (surprise) the Cool Start Kit-and procedures such as regular compressor washes can have benefits beyond making it to recommended hot section inspection (HSI) and TBO (3,500 hours for all three models). Ultimately, the superior pressurization system in the 400LS (under 10,000 feet at flight level 410) was paramount in the decision-making process to safely conduct international and oceanic flights above most weather and busy traffic altitudes, along with 50 KTS faster speed available on demand.
