Weve done the interior its still beautiful and painted the airplane in colors we like. With 24 volts required, the pumps are Major design revisions were made, and in October 1969 the prototype PA-31T-essentially a PA-31P with turboshaft engines-flew. Turboprop Aircraft. So we now face the dilemma confronting many fellow airplane owners, whether they be the proud possessor of a Cessna 172 or a Falcon 50: what to do with a great airplane of a certain age that is bumping up against another mandated and expensive intervention. When the IIXL was announced, Thomas Gillespie, then Pipers head of marketing, was asked if production of the II was going to end. INSTALATION AFTER 10 UP. As a result, the passengers either froze or cooked, and there never seemed to be a good fix for that. Both the II and IIXL can carry eight. 269 0 obj <>stream All rights reserved. 0000144133 00000 n The cabin is fine for three or four passengers even on longer flights, especially with the club seating arrangement. The two most important areas are avionics and autopilot/flight control systems. None of these occurrences was surprising. I was scared off by the low production number, the low number still flying, and the possibility of having the airplane grounded for long periods or even permanently. and apparent space. Maximum operating altitude for the I and II was 29,000 feet, but in 1983 the II was approved for 31,000, as was the IIXL. Discussion in 'Flight Following' started by NadJ, Aug 9, 2021. It frequently and for no reason pops the circuit breaker, usually at FL 250 or higher, so that it becomes a trifle brisk in the cabin. Chevenne 400 Ls with 5 blade perpillers has 1000 h.p engines too. Taking your Cheyenne to just any good technician could result in missing one or more procedures. A mock-up is. A friend and I seriously considered a Cheyenne a couple of years ago and I still think a Merlin would be a decent choice for what were doing. 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. 91 or F.A.R 135. the company would, completely out of character, do something either executive turbine fraternity. Full flap speed is 148. To the pilot, such an airplane will have a normal feel. had the aircraft off the runway and heading up at an amazing rate of climb. In the summer, when the effective density altitude is higher, attempting to hand-fly at that altitude is simply impossible. Compared with the Cheyenne II, the PA-42-720 was about 1m (3ft) longer, was powered by 537kW (720-shp) PT6A-41 turboprops and introduced a T-tail, the most obvious external difference between the PA-31T and PA-42, as well as the most significant change to the series. 17 0 obj << /Linearized 1 /O 19 /H [ 1122 283 ] /L 38316 /E 23523 /N 5 /T 37858 >> endobj xref 17 36 0000000016 00000 n 0000001067 00000 n 0000001405 00000 n 0000001612 00000 n 0000001748 00000 n 0000002090 00000 n 0000002404 00000 n 0000006240 00000 n 0000006446 00000 n 0000007290 00000 n 0000007475 00000 n 0000007966 00000 n 0000008485 00000 n 0000008975 00000 n 0000009725 00000 n 0000010134 00000 n 0000017979 00000 n 0000018000 00000 n 0000018781 00000 n 0000018802 00000 n 0000019444 00000 n 0000019465 00000 n 0000020118 00000 n 0000020139 00000 n 0000020727 00000 n 0000020748 00000 n 0000021428 00000 n 0000021449 00000 n 0000022091 00000 n 0000022200 00000 n 0000022221 00000 n 0000022916 00000 n 0000022937 00000 n 0000023294 00000 n 0000001122 00000 n 0000001384 00000 n trailer << /Size 53 /Info 16 0 R /Root 18 0 R /Prev 37848 /ID[] >> startxref 0 %%EOF 18 0 obj << /Type /Catalog /Pages 15 0 R >> endobj 51 0 obj << /S 120 /Filter /FlateDecode /Length 52 0 R >> stream But Ill tell you honestly, I still crave that 400LS! However, as speed built up, so lateral stability improved and we were very The average Janitrol event costs about $2,000, which includes a deep-cycle charging of the ni-cad batteries. Whats in a name Both in their design designations and marketing model names, there is a lot of confusion about what is what. Control authority is insufficient for a strong crosswind landing, so we learned to use differential power very early in our training on the Cheyenne. PIPER Cheyenne 400 | SKYbrary Aviation Safety But Piper's product support is getting better. The PA-31T3 is a hybrid of the Navajo Chieftain (unpressurized) fuselage with the flying surfaces and engines of the Cheyenne I.

The aircraft The PIPER Cheyenne II, manufactured from 1974-1983, requires a 2 person crew and can transport up to 5 passengers. Who knows what the relative retained value of these airplanes will be 10 years from now? My boss did the same: I wanted the King Air, but it was too costly then. A review of briefs of the 56 accident and incident reports a typical five-year period include eight fatal accidents, two of which were in commercial T-1040s. The numbers The PA-31T was produced from 1974 to 1983. In ground handling and during cross-wind operations it is especially troublesome, since it fights the desired control inputs. When I am not working, eating or sleeping, you can find me there. With a fuel capacity of 570 gallons of usable fuel on tap, the 400LS can fly more than 2,000 nm at that setting.

And archaic autopilots can represent in-flight hazards if they are not meticulously maintained and rigged. Cheyennes used PT6A-28 versions of the turbine engine. The lower maximum power of the I together with a narrower cg range, climb power limits and the forward bias of loading equations in the IIXL because of the stretch forward of the leading edge as well as an aft cg limit that is also two inches forward of the limit in the original Cheyenne make longitudinal stability and pitch performance satisfactory without artificial aids. Piper Cheyenne 400LS - Centurion Jets - Private Jet Company The massive Dowty-Rotol composite propellers are expensive and have only eight inches of ground clearance, leading to erosion problems.

In Kellys words: None of these planes should be running around without this modification.). [3], The 400LS made aviation history on 16 April 1985 by setting two new time-to-climb records for its class (C-1e Group 2, 3000m and 9,000m) and shattering two time-to-climb records for all turboprop classes (6,000m and 12,000m): with retired United States Air Force Brigadier General Chuck Yeager at the helm of N400PS (with co-pilot Renald "Dav" Davenport flying right-seat), the aircraft departed from Portland-Hillsboro Airport's Runway 31L, immediately reached a 5,959-foot-per-minute climbout and achieved its 3,000m record in 1 minute, 47.6 seconds; the 6,000m record in 3 minutes, 42.0 seconds; its 9,000m record at 6 minutes, 34.6 seconds; the 12,000m record at 11 minutes, 8.3 seconds (time-to-altitude records were captured by on-board video camera aimed at relevant panel gauges, timed with superimposed timer; also verified by Hillsboro Airport tower personnel via radar, using encoded altimeter data transmitted from aircraft to tower via transponder). Careless operation has the obvious consequences. Vref pegs the 400LS value at $1 million for a 1984 model to $1.22M for a 1992 model.

The Piper Cheyenne 400LS is powered by two Honeywell TPE 331-14 engines with 1,000 shp each. Insulation and trim was changed to increase finished interior dimensions. Piper used panel mounted King Silver Crown avionics in the I, a departure from tradition to achieve the price objective. The last was when management decided the Cheyenne IV would be dubbed the 400LS but all other models would remain Cheyennes. Start your free trial today! (Note that the longitudinal stability problem is at its worst at aft loadings, and if the range is exceeded all bets are, of course, off.). company limited itself to producing conservative if not down right Maximum climb power was reduced and recommended climb speeds raised to keep the airplane further from the SAS operating speed range (nominally, 121 KIAS and slower). Taxiing is straightforward and with the checks Its power-to-weight ratio of 6 lbs/hp allows for a climb rate of 3,200 feet per minute and a cruise speed of 350 knots.

For operators of the PA-31T, pitch instability should not be a concern if the airplane pitch system is modified to the latest specification (including the bobweight), the SAS is maintained properly, weight and balance limitations are observed and current limiting power settings and airspeeds are complied with. The Cheyenne 400LS is the largest and most powerful of Piper's turboprop twins, derived from the PA-31 Navajo. We did a hot section on schedule on the right engine almost four years ago. 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. If you train for and respect the airplanes high performance, understand the IIs loading limitations, and look beyond the stability augmentation system brouhaha, the Cheyenne will reward you with pleasant handling, great capability, and classy ramp presence. One famous such move was to call in Ed 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. Significant improvements were made throughout the product line in terms of maintainability, rational human factors-oriented redesign and in overall quality. Some people think the Cheyenne I is a better airplane because it has no SAS system. But, what exactly was wrong with the original airplane? Quick Look: Piper Cheyenne 400LS - AOPA be a direct competitor to the staid Beechcraft King Air 200. and there are built in data recorders. 0000093388 00000 n The first Piper Cheyenne was flown in 1969 by essentially hanging two PT6 turbine engines on the Mojave. It carries more and further and does it all for about half the cost of a comparable bizjet. 0000013013 00000 n in other turboprops.
