0000068591 00000 n Its empennage was enlarged for stability at higher speeds and altitudes, and its fuselage was strengthened. HVMo0WfSd@ qaz{!m"[XO_ 'H'Si>'&YU,6{6e_6Wv?oXZEdMgKif40w_jI)B-a?ffd$d^SD'": In 1975, he acknowledged many shortcomings and promised major improvements would take place in quality control and customer support. after the King Air was launched. The Cheyenne II is a bit of a handful, and not one in which a low-time or untrained pilot moving up from piston engines should fool around without first-class training. Piper was never noted for sophisticated engineering. 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. The cabin is so well insulated, this Even if misuse or abuse of a system or poor procedures dont lead to an incident or accident, improper operation can easily lead to unserviceability and increased maintenance cost. The PA-31T requires more of pilots than the -31T1 or -31T2 in terms of systems knowledge, planning and in-flight management. One of the most annoying characteristics of the Cheyenne is caused by the aileron/rudder interconnect. 0000004648 00000 n Both the II and IIXL can carry eight. The longitudinal stability characteristics and the SAS were fully covered in the November 1, 1981 issue of The Aviation Consumer. Mu2 fits the bill. Corrosion of the airframe has been rare, thanks to Piper's use of extensive anti-corrosion treatments and epoxy primers. Passenger comfort is good in our aircraft. The two most important areas are avionics and autopilot/flight control systems. Other factors contributed to this, foremost among them a battle for control of the company that began in 1969 and that was not resolved until 1977 and the flood that devastated the Lock Haven plant. 0000094577 00000 n There is My most trusted advisor is Bill Turley, a friend for 25 years and owner of our maintenance base, Aircraft Engineering in Bartow, Florida. The 400LS was initially designated as IV before finally being called a "400 . compresses and clearance decreases. Aircraft Owners & Pilots Association Find it free on the store.

PDF Piper PA-42-1000 - McFarlane Aviation Only three ADs apply specifically to the I and none to the IIXL, although most apply to all three. When you think about it, how can I justify taking the chance of just overhauling our own engines? PAPI Price Estimate Model Year (as of June 1, 2022): $1,308,533 Performance specifications Horsepower: 2 x 1,000 HP Best Cruise Speed: 334 KIAS Best Range (i): 1,879 NM Fuel Burn: 99.7 GPH Rate of climb: 3,242 FPM Rate of climb (1 engine out): 997 FPM Ceiling: 41,000 FT 0000092936 00000 n If the design has died with the old Piper Aircraft Company, Long-legged pilots are a bit jammed into the cockpit, especially in models with gussied-up interiors such as cabin dividers and refreshment centers which tend to impose on cockpit chair movement range most. Your email address will not be published. Two feet were added forward of the wing leading edge. Piper management was slow to accept the turboprop engine; some members of the Piper family were said to be set against it. Gear and flap speeds are sufficiently high to fit in to a wide range of traffic situations. If you're stepping up from a Seneca, the 400LS is too far away, too dicey to handle (at least on the t/o-run), too expensive to operate and with parts difficult to locate (only 45 built - 2 known crashes). The difference between the left front seat and a cabin chair can be substantial, especially if propeller-induced vibration is being transmitted from the aft fuselage). As with the Cheyenne I, there is no stability augmentation system. There is PDF B/CA Analysis: Piper's Cheyenne 400LS This and other systems were rationalized with the 1978 model year. Quality and quality control were not characteristics widely associated with Piper products of the time. The PA-31T3 is a hybrid of the Navajo Chieftain (unpressurized) fuselage with the flying surfaces and engines of the Cheyenne I. little doubt that Piper's PA-42 Cheyenne 400LS is the hot rod of the Our problem is that the right engine from day one has periodically and suddenly lost two or three quarts of oil. Most can be laid to insufficient knowledge of systems, lack of proficiency, failure to use check lists and other human performance issues. For a large number of buyers, the early models of Pipers Cheyenne series fulfill these requirements. Designed to provide a lot of performance for a comparably low price, the much-maligned Cheyenne still is a relative bargain for the kerosene crowd. The majority of the flights were flown above most airliners in comfort, style and at a fuel cost less than economy class tickets for the same itinerary. Taxiing is straightforward and with the checks shows that this is clearly a problem. Visibility from the cockpit is a real shortcoming until the 1980 model year. A power-to-weight ratio of 6 pounds/horsepower speaks volumes about the performance capabilities of the 400LS. Even if your insurance company were willing to let you get away without top notch training, you should get it. 0000082556 00000 n The Piper Cheyenne 400LS, PA-42-1000 is the final development and improvement of the venerable Cheyenne line of twin turboprop business aircraft. 0000002637 00000 n The Cheyenne IIXL, manufactured from 1981 to 1984, is basically a Cheyenne II with a 2-foot stretch all of it forward of the main spar. Apparently, any 0000002116 00000 n There is no major pattern. They made 620 shp, and therein lay a problem. Guess what? 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. By early models, we mean the original Cheyenne (later renamed Cheyenne II), the Cheyenne IA, and the stretched Cheyenne IIXL. And I have invested a small fortune and an inconvenient amount of time to the replacement of all manner of gyros. One reason for these problems may be that a pair of hurricanes smacked Piper's Vero Beach, Fla. plant in 2004 and destroyed or severely damaged 300,000 square feet of it. Despite the very noisy reputation of TPE331 on the ramp, passengers can comfortably carry on conversations without headsets during cruise. There were some cabin changes but that was about it. The instructors will put the pilot through aft-loading drills in the simulator, as well as many other things that are life-savers. As per the fifth paragraph in this article, 351 KTS at 25,000 feet (or 290 KTS at 41,000 feet) on 60 gallons of Jet A/hour, and a range of 1,800-plus nm with IFR reserve. And yes, when Pratt & Whitney (now Pratt & Whitney Canada), manufacturer of the PT-6 went on strike during Beechcrafts production of the A-100 King Air, Beech made the necessary modifications to the airframe to accommodate the Garret Engine, calling it the B-100. Rotol propellers (whose diameter is the same as the chassis length of a PIPER 400LS. The lack of suitable piston engines, however, was a major factor in the failure of Pipers own Fat Albert, the Pocono. I do know that when Piper modified the Malibu to make the Meridian, there were substantial changes. general aviation may be immeasurably poorer. Although the undercarriage legs have been So the whole package can push $700,000. Back in the 1980s, Piper employed Gen. Chuck Yeager to set various time-to-climb records in the 400LS. It can operate out of 3,000ft (900m) runways with a 97kn (180km/h) minimum control speed, similar to a King Air 300; it can operate from much shorter hot and high runways than a Citation I and landing is shortened by the rotating speedbrake effect of the propellers in beta pitch. The Cheyenne has the capacity for 1-2 crew members and 6-9 passengers. In this condition, you could take off, climb to 29,000 ft, cruise at 250 KTAS or so, and have an IFR range of about 1,170 nautical miles and an endurance of 4 hours 30 minutes. It is powered by PT6A-11 engines rated at 500 SHP. 0000179961 00000 n I just saw a perfectly flyable Beechjet get parted out because the cost of the upcoming service interval essentially totaled the aircraft. It can hold 3,819lb (1,732kg) of fuel plus two passengers with baggage, while each extra passenger costs 100nmi (190km) of range. You've disabled JavaScript in your web browser.

The Piper Cheyenne 400LS, PA-42-1000, is the final development and improvement of the venerable Cheyenne line of twin turboprop business aircraft. Who knows what the relative retained value of these airplanes will be 10 years from now? The PA-42-1000 Cheyenne 400LS seats up to 10 passengers plus 1 pilot. Insulation and trim was changed to increase finished interior dimensions. 0000022418 00000 n Performance data for Merlin III series online is lacking. ]m3IfeRCo~*k#'1LT=LzV_eWs4zSbXA? be a direct competitor to the staid Beechcraft King Air 200. He writes that his facility currently supports about 20 Cheyennes along with a number of other turboprops. It is derived directly from the popular III series but utilizes powerful TPE331 engines with four blade propellers which produce faster airspeeds than its predecessors! Each inboard main cell has two submerged boost pumps to supply fuel to the engine. -n!Zf`Wb | 9jL+_.6b|*3CY>D{}cLtGc"N%%y,IgR?/Mp6e>oBN)RLsSp#fS-4[4TkH-%K]u*[44Y#n These trips can often be made nonstop in our Cheyenne, but a Meridian would require a stop for almost all of them. A bonus is the fact that it is a beautifully aggressive and unique airplane. The aircraft 181 89 Those in the market for a used, entry-level turboprop twin have a lot of choices these days. By the late 1970s, operators also turned to turboprops for even more efficient engines and better payload and range than most business jets, albeit a slower speed. One of the most annoying characteristics of the Cheyenne is caused by the aileron/rudder interconnect. For an aging airplane, the Cheyennes have remarkably few major maintenance problems or airworthiness directives. There is a lot to recommend the single turboprops. What's not to like? Talk about paying for the Piper. No airplane in this category should be considered a weekend toy. Compared to the I, these engine improvements gave the IA up to 12 more knots at the IAs service ceiling of 29,000 feet and about 6 knots at maximum cruise power and 12,000 feet. The 400LS has the Cheyenne III airframe but is powered by counter-rotating 1,000 shp Honeywell TPE331-14 engines with four-blade propellers.The cabin normally accommodates two crew plus six passengers with a rear restroom or seventh seat.
