The 421A type was approved 19 November 1968, powered by two Continental GTSIO-520-Ds of 375 hp (280 kW) each, maximum takeoff weight 6,840 lb (3,103 kg) 1984 models starting with constructor number 195 used lighter weight four-bladed McCauley propellers. Plastic interior pieces for Piper aircraft. Production was spotty thereafter Externa länkar. The empty weight is 5488 lb (2489 kg) and the gross weight is 10,165 lb (4611 kg). On February 22, 2018, at 1939 eastern standard time, A Cessna 441 Conquest II airplane, N771XW, impacted terrain following a loss of control in Rossville, Indiana. 177 Cardinal. MaintenanceThe Conquest, as one might expect from such a complex aircraft, has had its share of service problems. The Cessna 441 with Dash 10 engines is in a class by itself. Suddenly the Citation looked a lot less attractive than a (relatively) fuel-efficient turboprop. The company swallowed the entire cost, providing painted, balanced and ready-to-install tail assemblies to owners in the field, and picking up the cost of customer transportation while the airplanes were retrofitted. Manufacturing FAA-PMA approved interiors since 1949. 0295 since January, 1983. We received no owner reports about single-engine handling qualities. The Cessna 441 with Dash 10 engines is in a class by itself. The Conquest Aircraft Operators Group, ((912) 244-1568). Serial 173 and later (1981 models and up) were approved to fly up to 35,000 feet-5,000 feet above the original certificated max altitude. Cessna reengineered the entire tail, significantly beefing it up and retrofitting the fix to all existing airframes. This can happen during the approach (and has) or immediately after landing. Occasionally the heat distribution during high altitude operations gets a bit tricky, but overall very good. Some 203 are registered in the United States. The Citation could fly higher and somewhat faster than a turboprop, albeit at the cost of greater fuel burn and shorter range. Hover over image to zoom. Early Conquest buyers actually benefited from the whole unfortunate affair. 120, 140, 140A. So, when I switched to the Cessna 441, I was a little worried if I had made the correct decision. That same combination promises a continuing place for the trusted Conquest II … It literally has no bad habits. This fix was claimed to be fifty times stronger than it needed to be. The reason that Cessna was so quick to find the problem with the Conquests tail was that the company had already known about it: The elevator and trim tab had been giving trouble for years. PerformanceThere have been several turboprops introduced since the Conquest came out, notably aircraft like the Beech Starship and Piaggio Avanti. $317.35. Other changes included the usual evolutionary avionics upgrades. West Star can also install a custom interior to convert a 441 to an air ambulance. eleven-seat light turboprop corporate aircraft with retractable landing gear produced by the US-American manufacturer Cessna Aircraft Company. Cessna claims the new inspection and life-limit rules are necessary. I have flown all of the current turboprops and am typed in the Lear and Citation. There were also some reports that reflect poorly on Cessnas quality control, such as multiple rivet holes for the aft attachment of the horizontal stabilizer, oxygen regulators installed backwards and four-ply tires installed at the factory instead of the required six-ply. The Conquest has excellent speed, range and climb performance, and its fuel efficiency is better than any of its contemporaries. I do think the fire/firewall shutoff buttons should have been located outboard of their respective annunciator panels; might have reduced the risk of pressing the wrong one at a critical moment. The Piper Cheyenne III is fast but has poorer fuel efficiency and 250 nmi (460 km) less range. The autopilot pitch servos should be inside the heated pressure vessel. Unless otherwise noted, these reviews carry product pricing from the time of the original review. There are two shops that do mods on the Conquest II. The company changed course, and replaced the 431s enormous Continentals with a pair of Garrett TPE-331-8 turboshaft engines producing 636 HP apiece. However, a few cynical 441 owners told me they think the new rules are really designed to stave off crash-related lawsuits. Once again, we had expense and downtime fooling around with recompensation and Lebow tests. The airframe still has a few bugs, though. The material is very reflective, and tests show that the cabin interior temperature can be reduced to near-ambient temperature on the hottest of days. The panel layout was the best in the business in 1983 and very good even now. During the demonstration tour that followed certification, problems continued to occur. HistoryIn the aviation heyday of the 1970s, Cessna made a bold move by completely ignoring the fast-growing turboprop market (then populated by Beech, Mitsubishi and Rockwell, with Piper soon to arrive) by introducing the Citation fanjet. The last Cessna-specific AD was 92-16-18, which had to do with replacement of Cessnas pedestal commuter passenger seats. It even got to the point that the flight test department started asking management to redesign the tail. Runway performance is about average; accelerate-go distance is about 4,000 feet at gross weight and standard conditions. The trailing beam landing gear makes nice arrivals the rule rather than the exception. He also provided a 10-item list of tail components which had to be changed during the tour. Multiple redesigns and beefups didnt solve the problem. And were pleased to note that the Conquest flight manual drives home the fact that a slight bank into the good engine (which results in a skid) is necessary to achieve the listed single-engine performance. AD 93-2-1 calls for replacement of certain fuel manifold assemblies. The Cessna 441 went down around 7:30 p.m. in a field near Carroll County Roads 500 West and 600 South, just north of Rossville. Executive Wings does the engine conversion, prop conversion, plus soundproofing packages and winglets. Wheel-well modifications. Engineers said it shouldnt be placed low in the propwash where it would be buffeted, while management disagreed. CESSNA 441 “CONQUEST ... Cessna entered the propjet market in 1977 with deliveries of the Conquest. (The piston version of the airplane became the 404 Titan.). The plane took off from Eagle Creek Airport in Indianapolis at 7:21 p.m., according to flight records. General Exterior and Interior. The latest major catastrophe appears to be the engines. Cessna 441 Conquest Aircraft Information. Converting to Cleveland brakes is a virtual must for cold latitude operations. Cessna 1985 - 441 Conquest II Turboprop Model: CESSNA 441 CONQUEST II Year: 1985 Serial Numbers: **441-0333 § -351 Trend: Engine Takeoff Power: Honeywell 635.5shp • TPE331-8-403S Average Overhaul $ Installed: 250,000 Engine TBO Hours: 5000 Max Seats: 11 Appraisal Points: Prcd w/Collins per base avg • add for -10 eng conversion It also has a trailing-beam type main landing gear for soft touchdowns and a wide stance for good runway handling. At 750 hours we were getting 260 knots instead of the original 290. A 441 with Pratt & Whitney Canada PT6A-112 turboprops was flown in 1986 but did not enter production. The high aspect ratio wings use bonded construction techniques. Visit AvBuyer today/ 0006, the accident airplane, was squawked for a trim problem only a month before the accident. Almost as soon as the Conquest started flying, however, disaster struck. The original design from 1972 for this aircraft was known as the Model 435 and was to be powered by Continental GTSIO-520X engines with three bladed propellers. The Cessna 441 Conquest ll was the first turboprop powered by Cessna and filled the gap between their jets and piston engine aircraft. At the time, it seemed a reasonable idea. The first 62 airplanes had defective nose wheels, but even the improved model on later aircraft should be modified. The airplane is also very comfortable for up to eight people.-Charlie Hillard Fort Worth, Texas. 93-15-11 and 92-26-7 concern various gaskets. A Conquest encountered a severe tail vibration and pitch-up, but was able to land safely. Also With This ArticleClick here to view charts for Resale Values, Payload Compared and Prices Compared.Click here to view the Cessna 441 Conquest features guide. I operate at 29,000 to 33,000 feet and the fuel burn is the same as the 425s was at 24,000 feet and 250 knots. If you are a diehard Flight1 Cessna Conquset 441 fan, you have been flying your favorite bird for at least a year (or two) now, and you are close to TBO. Over 12,000 part numbers in stock, ... Used Cessna 441 Refreshment Center Seat_Pivot_Arm_LH. The Piper Cheyenne 400 is 45 kn (83 km/h) faster but burns fuel like a light jet.[2]. This ought to result in quicker, cooler starts, and therefore lower hot-section inspection and overhaul costs. $950.00. Very soon into the test flight program, there were problems with the trim tab actuator loosening. It should be noted that even without the DOA, the airplane would probably have been certificated. As we noted above, all aircraft below serial number 110 (78 and 79 models) are essentially identical, having been updated during the great tail retrofit. When the airplane was flying again with a new tail in December of 79 (and a number of other updates and improvements), I was a fairly disgruntled customer. From a 1978 FAA statement: In view of the very general language of the regulation…there is nothing in the record to indicate that Cessna did not fulfill its responsibilities under Parts 21 and 23. Seating arrangements range from eight to a rather crowded eleven. 175 Skylark. Well in addition to getting the engines rebuilt, the author decided to spring for a few virtual dollars (and real paint time) to finally get the repaint and cabin always wanted. Comfort The Conquest has a big cabin. To protect the reputation of the Conquest, Cessna went to great lengths to support the plane. The tail had been a point of contention during the design process. After the fleet was grounded and Cessna made its statement about the cause of the breakup, the company beefed up the actuator yet again. For more than five decades, active and dedicated aircraft owners and pilots have turned to AVIATION CONSUMER to answer their most important buying questions. The Mitsubishi MU-2B-60 has a similar fuel burn and speed but flies lower. But fuel consumption is far less than the MU-2s. What other prop jet can go to 35,000 feet, fly at 300-plus knots, burn 65 gallons per hour and fly 2,000 mile legs? 207. The new props reduce noise, improve acceleration and climb. Under pressure to bring the airplane to market, Cessna used its FAA-granted Delegated Option Authority and certified the airplane as it was. The Dash 10 conversion is the single best performance conversion I have ever put on an airplane. 1963 Cessna 182. Engineers decided that the tab actuator wasnt the problem, but a symptom of vibration. It is a pressurized, 8–9 passenger turbine development of the Cessna 404 Titan. Data from Jane's All The World's Aircraft 1982–83[7], Aircraft of comparable role, configuration, and era, Twin engine turboprop aircraft produced 1977-1986, "Cessna Conquest II: Undervalued, Speedy, Fuel Efficient Turboprop", "FAA Clarifies Cessna's Life Limit For The 441 Conquest II", https://en.wikipedia.org/w/index.php?title=Cessna_441_Conquest_II&oldid=921581449, 1970s United States civil utility aircraft, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, Cessna 1000A Integrated Flight Control System, This page was last edited on 16 October 2019, at 15:51. The company provided loaner airplanes to Conquest customers during the second grounding, and refurbished the airplanes to the latest configuration before returning them to service. I flew the Cessna 441 a little over a year and then at 3,000 hours did the Dash 10 [engine] conversion including four-blade McCauley props at West Star Aviation in Grand Junction, Colorado. The Conquests single-engine performance is about average for the turboprops. (Only the Champions leak: look for AC igniters.). The Conquest will reach 30,000 feet in about 22 minutes, and its 35,000-foot ceiling in just over 30 minutes. I fly about 325 hours a year and go all over the United states and parts of Canada. Thats pretty good. The Garrett engines make the Conquest a bit noisier than comparable PT-6-powered aircraft, particularly on the ground. The defrost blower is completely inadequate for the job. The range is sensational. The cabin auto-temperature control is virtually useless. Beech had the widest variety, with several models of the 90, 100 and 200 series King Airs, Piper had the Cheyenne I and II, Mitsubishi had the long-and short-bodied MU-2s, and Rockwell had the Turbine Commander 690. The 441 Conquest/Conquest II stacks up very well against the competition in an area of great interest to turboprop buyers: Performance. 0295 since January, 1983. The result was the 441 Conquest. It seems the airflow around the tail is still capable of causing problems. It came on the market late in 1977 as a 78 model, about ten years after turboprop business twins were first introduced. Texas Aeroplastics replacement parts are made from top grade ABS plastic with an average service life of 15-20 years when properly fitted and professionally painted. While much more expensive than some of these aircraft, the 441 boasted a more recent design and better performance. Its nearly 13 feet long, longer than any comparable turboprop except for the cavernous 100 and 200 series King Airs. However, the NTS (Negative Torque Sensor) system on the Garrett engines, a type of auto-feather device that quickly sets the propeller to a near-feather position in case of power loss, should help the pilot out in the critical task of quick identification and feathering of the failed engine. $450.00. Twin Cessna Articulating Crew Seat Pivot Arm Seat_Pivot_Arm_RH. [2], It cruises at 316 kn (585 km/h) TAS while burning 480 lb (220 kg) of fuel per hour at FL290, while maximum range is 2,000 nmi (3,700 km) at 260 kn (480 km/h) TAS and 310 lb (140 kg)/h at FL350. West Star Aviation also does engine and prop conversions, along with soundproofing. I got reasonable service from that time forward. Cessna 441 Conquest II är ett tvåmotorigt, lågvingat monoplan från Cessna i helmetallkonstruktion försett med ett infällbart landställ.Maskinen rymmer åtta till tio passagerare samt en eller två mans besättning. Climb gradient is also very good. It would be good if the empty weight CG could have been an inch or two farther forward. There have been many irritating problems; i.e., new paint job, new windows, five changes of the pilots HSI (and finally installing a Collins PD-108), dozens and dozens of minor changes, all paid for by Cessna, I might add, to their everlasting credit. In Summer 2007, Cessna limited the Conquest II to 22,500 hours of air time for US for air carriers, an advise only for private operators.
