The Piper Malibu-Mirage is a head turner. During flights tests of simulated nose-up pitch trim runaways, it was determined that "manually stopping the trim wheel rotation could only be accomplished momentarily as the overpower force to counteract the electric trim was too high." It's 3 inches thick and has about a thousand pages. She knows how I drive. Bendix/King was more reserved. Instead, it identified various problems and made recommendations — 60 of them, in this case — for improving the airplane and its autopilot. The following month, after howls of protest, it rescinded the AD, then published another. In the Mirage, the pilot couldn't easily pull the pitch trim circuit breaker. The autopilot supplements in the Piper manual still contain this preflight check. In a press release, Piper's then-owner, M. Stuart Millar, added a line that all could agree upon: "...but a focus is needed on pilot training and systems familiarity.". To document test results, pressure-sensitive "Strip-a-tube" was applied the length of the horizontal tail's chord; this recorded pressure distribution over the tail. Structural testing and review of the Malibu/Mirage airframe came from several sources. Mark Gregory Aletky of Acton, California, was the pilot of the 1984 Piper PA-46-310P that crashed Friday morning in a field near Harrisburg. malibu mirage pa-46-350p sn 4636196 and up pilot’s operating handbook and faa approved airplane flight manual airplane airplane serial no. Because the accident aircraft all showed an essentially simultaneous failure of the wings and horizontal tail, great attention was paid to both static and dynamic load testing. The other proposed autopilot AD would require a cover for the pitch servo unit. Still, it's interesting to take a look inside, especially at those sections dealing with the autopilot tests. _____ regist. So were requests for interlocking the stall warning sensor to the autopilot (so that the autopilot would automatically disconnect if the stall warning activates), installing sensors that would disconnect the autopilot if airspeed exceeded 185 KIAS (the maximum speed for autopilot use), and changing the certification rules so that a single autopilot malfunction cannot lead to multiaxis deviations in aircraft attitude. The single-engine, six-seat plane known popularly as a Piper Malibu, is based out of Van Nuys, California, and is registered to Park City Aviation LLC in Park City, Utah. The airframe and autopilot passed the review. A Malibu pilot called Bendix/King, complaining that his autopilot would oscillate wildly in pitch during attempts to level off from descent. 8:03 a.m. The pilot and a passenger died in the accident. In spite of these and other quirks, the SCR team found the autopilot in full compliance. (Except for one accident aircraft, which was determined to have had a CG well aft of the design envelope.). It urged that pilots better familiarize themselves with the capabilities and limitations of the Malibu/Mirage's autopilot, flight director, and altitude preselect components. -A Piper Malibu crashed Friday, killing all five aboard, shortly after taking off from Edmonton en route to Winnipeg. 1985 Malibu that has everything needed and is already configured for a tall pilot or co-pilot. Among the most important, however, were those measuring stick force per G, in which control forces were measured at speeds between 130 and 200 KIAS, pulling anywhere from 1.2 to 3.05 Gs. In early 2018, I was cleaning out years of documents from file cabinets in my Kansas City based office. The report pointed out that in single-pilot operations — the kind typical of Malibu/Mirage flights — three seconds is too short a time to be representative. 13V5012 Van Heusen Men's Commander Shirt - Long Sleeve (White) A subsequent revision eliminated this check, which was also unusual. The Malibu/Mirage not only passed these tests — each one, remember, at different weights and CGs and conducted at 10-knot intervals — with flying colors, it exceeded certification requirements. from Cont. Another assumption was that it would take a crew just three seconds to recognize and correct an autopilot problem. Neither ASN nor the Flight Safety Foundation are responsible for the completeness or correctness of this information. Those affecting the airframe (strengthening the empennage with stronger rivets, inspection of elevator trim cable guide tubes) have, for the most part, already been addressed by owner compliance with previously issued Piper service bulletins (see "Pilot Briefing," April Pilot). Among them were original brochures from years of Piper production aircraft with an emphasis on Malibus, Mirages and Meridians. One proposed AD affecting the autopilot asks that the low vacuum warning lights be placarded as inoperative and that vacuum gauge markings (a green arc showing the range of normal suction values) be added. The pilot had been fighting the autopilot during his descents and inducing huge mistrims in the process. A failure of the autopilot computer's attitude-sensing capability, for example, is not annunciated. In most cases, suspicion about an airplane's design were raised by patterns of accidents taking place under similar conditions. Just a straight-ahead stall with no tricks.". Piper engineers kindly offered this author the chance to look at the footage. This maneuver requires precise timing because the goal is to obtain precise positive and negative G measurements for displacements from each 10- knot increment of airspeed. All were in-flight breakups; most occurred at altitude, some involved flight in thunderstorms, and some involved relatively low-time pilots. For example, Piper didn't have to perform stick force per G tests at speeds as high as 200 KIAS. These are good ideas for pilots of any high- performance, autopilot-equipped airplane. As far as most pilots are concerned, this is a world that has never seen the light of day — not in any classroom, and certainly not in any manual or check list. New Piper's current flagship product, the Malibu Meridian, is much more than simply bolting a PT-6 on the front of a Mirage. Eventually, a method of strengthening the V-tail's tail spar assemblies was developed by Beech, then offered to owners free of charge. Authorities say three people are dead after this fiery plane crash in Oconee County. The descent was accomplished by pushing on the control yoke. But it did, even though this was some 40 knots higher than the letter of the law. The aircraft was travelling from Nantes, France, to Cardiff, Wales. page 9-60. Malibu pilots tell of getting cruise speeds of 208 knots TAS at FL220 at 67 percent power and 212 knots true at FL250 at 75 percent. If you feel this information is incomplete or incorrect, you can. Was the Bonanza too slippery, too demanding for a low-time — or unproficient — pilot? When the desired altitude was reached, the pilot released the yoke, expecting the autopilot to somehow capture the new altitude. The FAA, Piper, and the NASA Langley facility validated the results of Piper's original calculations on the PA-46's aeroelasticity and flutter characteristics. -On June 26, 1990 near Rochester Hills, Mich. a Piper Malibu crashed, killing the pilot, after its airspeed suddenly dropped from 140 knots to 100 knots. Pilots also should understand that it's possible to program an autopilot climb that's beyond the performance capabilities of the airplane; commanding the autopilot to climb the airplane at a rate higher than it's able to execute, for example, can result in a stall. Fleeting, thousandths-of-a-second-long motions of the yoke are needed. Finally, on December 5, 1991, the review was published. to check the pilot's trim overpower capability.' Get the latest news on coronavirus impacts on general aviation, including what AOPA is doing to protect GA, event cancellations, advice for pilots to protect themselves, and more. Failure of the KFC 150's KC 192 gyro sensor can cause runaways in both pitch and roll simultaneously. Other disconnect features worked, so the chances of a completely out-of-control pitch trim runaway were almost nil (there are seven means of disconnecting the autopilot). That's because it is located on the copilot's side-wall panel, virtually out of the pilot's reach. Between May 1989 and March 1991, there were seven fatal accidents, six of them involving Malibus, one of them a Mirage. The aim here was not to load the test airplanes to their CG and gross-weight limits (that had already been done when the Malibu was first certified), but to duplicate the accident aircraft weights at the edges of the potential CG envelope for those weights. Addition of a gyro sensor monitor feature was listed among the SCR's recommendations. The pilot and two passengers were fatally injured. no. It hadn't been done before. But above all, the SCR's recommendations asked for more pilot education and better manuals and other product information. Revision FAA Approved Number and Revised Description of Revisions Signature Code Pages and Date Rev. This raised a question. Finish reading the text sections of the full report (don't bother reading the graphs or raw data unless you're an aeronautical engineer), and you'll come away with a greater respect for the airplane's strength, the researchers' professionalism, and, perhaps most important, the complexities of autopilots in general and those of the KFC 150 in particular. During the SCR's tests, it was learned that the low vacuum light switches sometimes did not illuminate when system suction dropped below normal levels. Another reason is that, until recently, the Bendix/King manual specified such a check during each preflight. That's better than three times the airplane's VNE of 198 KIAS and well into the supersonic realm. Did pilots do the check and ignore the findings? In March 1991, the FAA was moved to issue an airworthiness directive prohibiting Malibu and Mirage pilots from flying in instrument meteorological conditions. Piper's chief engineer of aerodynamics, Mal Holcomb, when asked if the SCR tests brought any surprises, said, "The strength of the tail. In addition, extra, out-of-trim stick-force tests were conducted. Piper Matrix, Malibu, Mirage, JetProp and Meridian Instruction. The airplanes passed this scrutiny with minimal fuss. "That 4.2 Gs was unintentional," said Schwartz, "I pulled a little too hard, a little too fast on one test and went outside the envelope for just a little bit. I'll have the latest on the investigation tonight at 10 and 11 @FOX5Atlanta pic.twitter.com/c83AVt6eCG, This information is added by users of ASN. On March 3, 2020, about 1634 eastern standard time, a Piper PA-46-310P, N43368, was destroyed when it was involved in an accident near Bishop, Georgia. Maybe that's because the SCR team uncovered some autopilot tricks, traps, and unknowns that it hadn't fully explored or understood before. There is also co-pilot instruments on the right side of the dash. To this day, certification rules still carry the three-second-delay requirement before initiating a recovery from an autopilot malfunction. The M600 also has a new wing marketing claims it s a clean-sheet design that carries 90 gallons more fuel than the Meridian, allowing the M600 50 percent more range, a 958-pound higher gross weight and 100 more pounds in the cabin with full fuel. Many of these disintegrations occurred in instrument meteorological conditions and with non-instrument-rated pilots at the controls. Piper’s original 1984 Malibu introduced cabin-class comfort to the single-engine market, and the Meridian has only continued and improved upon that tradition. Likewise, general aviation aircraft have had their share of reputation-damaging events. The pictures showed but the slightest, almost imperceptible, flexing of the horizontal stabilizer, and even then at only the highest G loads. Pilots of both models talk about making 1,100-NM trips with IFR reserves. It's important to remember that the SCR was just that, a certification review — not an accident investigation. This cannot be done in the PA-46-310P/350P airplanes because the pilot does not have enough mechanical advantage to manually rotate the trim wheel with the clutch engaged.". The analysis proved that the wings would begin to flutter at about 600 KIAS, the horizontal tail at better than 1,000 KIAS. PA46-310P. (PR990920) 3-11 Revised para. We'll probably never know the answer to that kind of question, but it came up again in 1989 and in a similar context. So the SCR does not blame. After 16 seconds, the airplane reached 200 KIAS. After 4.5 minutes, the airspeed was at 185 KIAS, and 2,000 feet had been lost. A proper autopilot descent requires the pilot to first disengage altitude hold, then use the autotrim switch to command a safe descent rate. Aside from its ramp appeal, it has a high-flying pressurized cabin, 200-knot cruise speed and its impressive range. The SCR report also mentioned other, simple bits of autopilot knowledge (affecting all types, not just the KFC 150) that should be emphasized in the course of autopilot training — such as never putting any manual restraint on the normal operation of the autopilot; large pitch mistrims could occur. The Piper Malibu may well be your choice if your flying will be high, a long range is needed in great comfort and between well equipped and serviced aerodromes. 1985 Piper Malibu. Instead, as AVweb's Dave Higdon writes, from the cabin to the panel to the spinner, New Piper's turboprop single is top of the line. In the case of the Mitsubishi MU-2 and Learjet, a series of fatal, unexplained plunges from altitude prompted Federal Aviation Administration reviews of these airplanes' compliance with certification standards. The Vero Beach company learned a long time ago that performance is important, but comfort can be an end in itself. For this reason, many of the autopilot malfunctions reenacted for the SCR review were conducted with recovery delays greater than three seconds. Not a member? This manual override capability must be demonstrated in other installations of the same system in other airplanes with similar servo clutch torque limit values. no._____ pa-46-350p report: vb-1710 faa approved by: peter e. peck d.o.a. As for the human factors aspects, the picture was less clear. Should an attitude-sensing signal be lost in flight, the flight envelope could be expected to be exceeded (60 degrees of bank) within five to eight seconds. During the mid-1990s, Piper found strong interest in a potential turboprop variant of the company’s Malibu Mirage. One Bendix/King official recounted a story that underscores the level of pilot misunderstandings. Once again, a certification review was ordered, and once again, it was determined that the airplane met the rules. Piper Malibu Matrix; Piper Meridian; Piper Mirage (350) Piper Mirage w/Avidyne; Piper Navajo 310; Piper Navajo Chieftain 350; Piper Pacer/Tri Pacer 125/135; ... 13V5010 Van Heusen Men's Tall Pilot Shirt - Short Sleeve (White) Van Heusen Commander Pilot Shirts. It turns out that the pilot initiated his descents with the autopilot's altitude-hold feature engaged. The Piper PA-46 Malibu and Matrix are a family of American light aircraft manufactured by Piper Aircraft of Vero Beach, Florida. TSIO-550C Engine Conversion. The empty weight is 2,608 lbs and the gross weight is 4,300 lbs. Currently, Piper offers the M350, M500, and M600 in the PA-46 family. In a descent from level flight at 160 KIAS, test pilots failed an attitude gyro sensor while simultaneously disengaging the vertical speed mode, bank angle went from 45 degrees left to 30 degrees right, and pitch angle went to 20 degrees nose down. The Cessna 210 is a brute and can also take you high whilst being well loaded with people or freight. Early Malibus were all piston-engined, but a turboprop version, introduced as the Malibu Meridian but now called the M500, is also available. Piper did a static load test of the Malibu's tail and found that it failed at 239 percent of its 3.8-G limit load, or approximately 9 Gs. In the late 1970s and early 1980s, the safety of the Beechcraft V35 Bonanza became a major issue. https://app.ntsb.gov/pdfgenerator/ReportGeneratorFile.ashx?EventID=20200303X93345&AKey=1&RType=HTML&IType=FA, https://www.al.com/news/tuscaloosa/2020/03/oconee-county-plane-crash-multiple-fatalities-as-alabama-bound-plane-crashes-in-georgia.html, https://www.usnews.com/news/best-states/south-carolina/articles/2020-03-03/single-engine-plane-crashes-in-georgias-oconee-county, https://www.ajc.com/news/crime--law/breaking-plane-crash-reported-oconee-county/dkKThsCoJBGUegBqyBSptK/, https://www.wsbtv.com/news/local/plane-crash-shuts-down-several-roads-oconee-county/MDY3Z47NEZHPBCBXRKFIAACUNE/, https://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=43368, https://flightaware.com/live/flight/N43368/history/20200303/1830Z/KCAE/KTCL, https://photos-e1.flightcdn.com/photos/retriever/400d20c113cc19950a41a28bafabcf84cab897be, Columbia Metropolitan Airport, SC (CAE/KCAE), Tuscaloosa Regional Airport, AL (TCL/KTCL), Updated [Aircraft type, Source, Damage, Narrative], Updated [Time, Registration, Total fatalities, Total occupants, Location, Source, Damage, Narrative], Unless otherwise stated: copyright © 1996-2020 Aviation Safety Network (ASN). That’s right, the ONLY one. One is that manually overpowering the electric pitch trim with the trim wheel is supposed to be a way of stopping a pitch trim runaway. Page 10 PIPER AIRCRAFT CORPORATION PA-46-310P, MALIBU PILOT'S OPERATING HANDBOOK LOG OF REVISIONS (cont) Revision FAA Approved Number and Revised Description of Revisions Signature Code Pages and Date Rev. Larry Grant bought the very first production Malibu. Incidentally, it took the airplane one second to stall when pulled up from 70 KIAS and four seconds (the regs set a three-second minimum for this test) to stall from 126 KIAS. These tests measured the amount of control force required to deviate from the airplane's trim speed and, as such, are important measures of an airplane's longitudinal stability: The farther you deviate from trim speed, the harder you must pull on the control yoke. Then Piper performed flight tests, using one of its own test aircraft (N9135D — the one used in the original certification process). The moral: Continuously monitor any autopilot's performance at all times. Again, most Malibus already had this fix completed, per a March 1990 Bendix/King service bulletin. Or did they not perform checks at all? Initial Training Syllabus Recurrent Training Syllabus Supplemental Training Pro-Pilot PA46 Rate Sheet Dave McVinnie started instructing in Piper PA-46 aircraft in early 2000 and is very active with the Malibu/Mirage Safety and Training Foundation. "But it all worked out fine. ", The videotape? ©2020 Aircraft Owners and Pilots Association. There was considerable speculation that the V35's V-tail design was partially to blame. Checked, or balked, maneuvers were also performed, at speeds ranging from 150 to 200 KIAS, at the different weights and CGs and at the standard 10- knot intervals. In fact, many industry professionals believed it was long overdue, so in 1997, the company announced it would develop such a turboprop. Most newer Malibu’s have really nice digital panels, and the older versions stand out for they will almost all have the older instruments. The NTSB's response took more of an educational tack. Instead, of course, the autopilot commanded an immediate climb back to the originally programmed altitude. Suspecting — as with the MU-2 — that autopilot problems may have been responsible for the crashes, the FAA also prohibited the use of the PA-46's Bendix/King KFC 150 autopilot for altitude changes. Mirage pilots talk about getting 220 knots true at FL230-250 at 75percent burning 18.8 GPH. In that three seconds, the airplane must not enter an unsafe attitude or condition. For Piper test pilot David W. Schwartz, the unchecked pullups were the hairiest of all in the SCR series. the horizontal stabilizer skin of a Piper Malibu fell away after the pilot had reported moderate turbulence. It was noted that excessive roll rates would not disengage the autopilot in this failure mode. On 7 February, Sala's body was recovered from the wreckage. These tests proved satisfactory, as well. Over the years, various airplanes have experienced design-related safety problems.

No trace … Apparently, water could pass by the servo unit and enter internal components of the autopilot. Thus, the PA–46-500TP Malibu … Page 5 PA-46-350P, MALIBU PILOT'S OPERATING HANDBOOK LOG OF REVISIONS Current Revisions to the PA-46-350P Malibu Pilot's Operating Handbook, REPORT: VB-1710 issued FEBRUARY 23, 1999. 1 Added Rev. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. Once again, the airplane passed with ample margins. Aviation Safety Network: Aviation Safety Network: Databases containing descriptions of over 11000 airliner write-offs, hijackings and military aircraft accidents. So the static longitudinal stability of the airplane could not be questioned. It turns out that the pilot initiated his descents with the autopilot's altitude-hold feature engaged. The descent was accomplished by pushing on the control yoke. The Piper Malibu Mirage is powered by a Lycoming TIO-540-AE2A engine. After failing the vacuum system during an autopilot-controlled climb at 160 KIAS, the system commanded a continuation of the climb. It gives you and your passengers air conditioned and pressurized comfort. 9-65 Corrected spelling. In its release, it said simply, "FAA personnel were also asked whether they had found any evidence linking the KFC 150 autopilot to any Malibu/Mirage accident, and their response was in the negative." A Malibu pilot called Bendix/King, complaining that his autopilot would oscillate wildly in pitch during attempts to level off from descent. One of them is that many pilots stepping up to the Malibu/Mirage's left seat apparently don't have sufficient respect for the kind of high-performance airplane that they've bought, nor the environment in which they fly. One third of the SCR team's 60 recommendations dealt with the Malibu/Mirage's autopilot systems. We have 19 PIPER MALIBU SERIES Aircraft For Sale. The SCR emphasized that the rules for autopilot certification came about in the era when Transport-category airplanes with two-man crews were the only autopilot users. This time, the reputations of the Piper Malibu (PA-46-310) and Malibu Mirage (PA-46-350) aircraft were on the line. This test goes as follows: (1) Trim the airplane to the target speed; (2) haul back on the yoke very quickly; (3) keep pulling until full elevator deflection is reached; and (4) measure the time it takes for the airplane to stall. Piper jumped for joy, saying "this proves what we've been saying all along...that there is nothing wrong with the airplane." But the autopilot recommendations seem to carry a greater sense of urgency than the rest. The review process consumed the better part of 1991 and involved the full cooperation of both Piper and Bendix/King. This was a significant finding for two reasons.
