incl. Musk and the FAA should declare a truce and get back to the remarkable work at hand. While I don’t doubt that a controllable carb (or fuel injection) would improve the 3300’s fuel specifics, somehow the drop from 7 gph to, say, 6 seems hardly worth the effort. You don’t want to be anywhere near that sucker when it blows.That’s a long way around to suggesting that the Jabiru’s operating speeds are, in many ways, conservative. This is a true story about a person whose identity I wish to protect. KOSH x 5 Flying a B-Model Conversion (Super Bee Baby!) This wasn’t a kind gesture on his part; he wanted the engine to remain exercised because an engine that sits begins to deteriorate. I will call him “Bill” as that is what his parents, Mr. and Mrs. Kelso, called him. The market culls the weak ones and the survivors see their numbers and applications grow. I won't be buying a new one. Jabiru 3300 engine; AP420 feathering hub; 64in diameter; Sensenich Composite Blades Z profile; AP420CTF-SNR64Z. Manuals and User Guides for Jabiru 3300. In 1998, unconstrained by teachers, Kerry scratch built a Sonex he polished and named Metal Illness. Surely an argument can be made that a certified engine is more reliable than a non-certified engine; they’re branded “certified” by the government and that must stand for something In simplified terms “certified” means the engine meets the FAA’s criteria (see 14 CFR, Part 33) for parts and systems reliability, performance, endurance, and the necessary support documentation for installation, maintenance and repair of the engine has been developed. Well, how about that?Jabiru’s first effort was a 1.6-liter (call it 98 cubic inches) but after the first 40 were delivered, the company turned its quest for more power into a new iteration, now displacing 2.2 liters (134 cubic inches) from a 97.5-mm bore and a comparatively short 74-mm stroke, and producing 80 horsepower. Maximum piston speed for the 3300 is 1602 feet per minute, compared to 1778 fpm for the Continental; at the Jabiru’s max-continuous speed (2750 rpm), it’s a modest 1335 fpm. Exhaust, Carburetor, Starter Motor, Alternator & Ignition System & Accessory pack. That may be a part that is physically bolted to the engine during its manufacturing process or a manufacturer’s specific oil or oil filter recommendation. ENGINE DETAILS: JABIRU 3300. Jim flew his Standard Gear, Jabiru 3300 Powered Sonex… Read More. This “green arc” is where the most reliability and longevity is derived. Thanks to the 74-mm stroke (2.91 inches), the piston speeds remain moderate. Pistons come from the GM/Toyota world, and the hydraulic lifters found in all newer Jabiru engines are right out of a small-block Chevy. Even lying shill Dan Johnson might admit Erwin’s CZAW Sport Cruiser, Mermaid, etc were designed for the superior Jabiru 3300 but supply (and Aussie disgust at Erwin’s business “practices”) forced him to resort to 912. The 3300 is a modular development of Jabiru's flat-four 2200 engine. )Once your gaze has wandered from the machined cylinders, they alight upon the fully CNC-machined cases. Both of these airframes have the same engine, yet they have different cowl openings. )Thanks to its greater displacement — the Jabiru six’s 3.3 liters dwarfs the 912’s 1201 cc (74 cubic inches) — the Aussie engine pounds out more power than even the turbocharged Rotax 914, and does so at much lower engine speed. An air-cooled engine cannot be properly cooled during extensive ground operations with its cowling on or off. 1) Issues regarding the measurement of reliability of the Jabiru engine The design standards do not require an acceptable level of reliability for aircraft or aircraft engines. Trust but verify, and get to know what “normal” is for your particular aircraft. Nope. Flying regularly is a significant factor in an engine’s reliability and longevity. ... My experience with hopped up C series and O-200s is reliability … There’s no prop control, no mixture. Related products. This is the standard installation of a Jabiru 3300 on a Sonex airframe, but duplicating this installation on a slower airframe may deliver poor results. Applicable to Jabiru 3300cc … After a few weeks of barnstorming he experienced performance issues, which ultimately grounded the aircraft and prematurely ended his summer of barnstorming. Reliability however is the ability for a machine or component of a mechanical system to operate consistently or repeatedly without failure within the expected durability timeframe. I am thinking about building a j3/pa11 with one in it similar to the texas sport cub. As everyone knows, there are specifications and company propaganda, and then there’s flying. So a four-cylinder Lycoming, for example, has but three main bearings, albeit very large ones, particularly the massive bearing between the prop flange and the first set of cylinders. Who knows how it happened—an assembly-person who lost track of what he was doing?—but it happened. DAR Mel Asberry answers a reader’s question regarding the Experimental/Amateur-Built eligibility of an airplane he’s building with parts salvaged from a Cessna 175. I have been considering a few engine options, but it looks as though the simplest and most cost effective solution is to go with a replacement Jabiru … Failure to do this can result in glazed cylinders, whose symptoms include lack of power and high oil consumption. piston speed. Rotax failure rates have always been lower than Jabiru failure rates but it was the twisted data that CASA used in the 2014 Engine restrictions At the height of it CASA lists 40 Jabiru engine failures but this was reduced to 12 after such things as running out of fuel and shutting the engine down after an oil leak etc were removed from the list. Bottom line? Kerry is on the web at. Matching an engine installation to an airframe is critical to the engine’s success. There isn’t a single documented engine failure in the soaring community. We supplied our first EFI system for a Jabiru 3300 back in 2004 and are now working on parts to fit SDS on the new Gen 4 Jabiru engines. (A basic 912 is some 50 pounds lighter. Ltd. (Australia). This air-cooled engine is in an engine test cell where it is kept cool with a custom baffle that forces the prop wash through the cylinders. © 2021 Kitplanes.com. JABIRU 3300 AIRCRAFT ENGINE DOCUMENT No. Here are pics of two different props I ran on my plane and you can see how the wood prop would push more air into the cooling ducts on the ground than the Warp drive prop would. 10-13-2010, 02:08 PM. Granted, it could be hard to argue an engine failed because of the oil, but it would be easy to argue one failed because an oil vastly different from that recommended by the manufacturer was used. We both received our bikes at the same time, in the same geographical location. The Jabiru glistens in beautifully CNC-machined 5000-series aluminum. Does any one have any helpful info on reliability … Oil grows weary of clinging to the wear surfaces it’s supposed to protect and retreats to the oil sump. incl. This page contains photos of a Jabiru 3300A Solid Lifter engine under going a bulk strip and rebuild. Common sense must prevail, however, and the throttle must be manipulated as necessary if the oil or cylinder head temperatures threaten to spike. All engines, regardless of manufacturer, are mechanical devices and mechanical devices can fail. Clearly, the soaring community has engine reliability figured out. Notice how the cylinders are staggered side to side? An owner of a popular 6-cylinder engine, in his quest for even exhaust gas temperatures, replaced the stock intake manifold, mechanical fuel pump, and carburetor with an aftermarket fuel injection system. Jabiru’s literature calls out eight bearings on the six-cylinder engine, apparently counting the split shells on the crank nose as two. In fact, Jabiru lists the 75% cruise consumption of the 3300 as 6.87 gph, which calculates out to a specific fuel consumption of 0.51 pounds per hour per horsepower. The valvetrain is similarly conservative, with a single, underslung camshaft, two valves in each cylinder and simple screw-and-locknut adjustments in the heads. The Sauer seem interesting but what about support and reliability? The J2200 is an 80HP aircraft engine manufactured by Jabiru in Australia. In many respects, the Jabiru follows the conventions set by the Rotax 912, arguably the most popular “nonstandard” aviation engine in the last decade and a half. The 3300 does tend to be worse than the 2200 simply because it has a centre cylinder on each side which requires an even better airflow than the 2200. This became the Jabiru 2200. All of these engines are capable of providing great service. New Jabiru Engine Pricing After years of development and rigorous testing, we are excited to announce the availability of the new Generation 4 Jabiru engine 3300 Generation 4 (6-cylinder, 120 hp @ 3300 RPM) – $18,900 2200 Generation 4 (4-cylinder, 85 hp @ 3300 RPM) – $14,900 When you see a deviation from your normal, take it as a sign of trouble and investigate. It’s a simple and largely effective system. To me the best value for power and weight is the 3300. Similarly, while the Rotax employs motorcycle-style Bing carburetors, the Jabiru has one feeding an under-engine plenum that shares space, Lycoming-like, with the oil pan. All rights reserved worldwide. Published: March 9, 2006 | Posted In: Sonex News. ENGINE DETAILS: JABIRU 3300. Nice touch. A Cirrus floated from the sky on its parachute after its engine lost power. The Jabiru 3300 is a six-cylinder direct-drive air-cooled aircraft engine from Jabiru Aircraft Pty. Maintenance can be a double-edged sword. At high volume, like takeoff, the slide rises, allowing more air to flow. This site uses Akismet to reduce spam. It presents itself as an immediate component failure and is traced to a defective part or workmanship. Jabiru is a reputable manufacturer of engines and aircraft. Jabiru uses a removable prop flange so that replacement of the crank nose seal — a fairly ugly job on a traditional flat engine — is quite easy. My friend’s bike developed a knock within minutes of starting the engine. I don’t have statistics but my observation from current Aussie users of the Jab3300 who post on that forum is that reliability is improving with the mods that Jabiru … Your IO-520 is whipping along at 1800 fpm at takeoff and 1533 fpm at a leisurely 2300 rpm cruise setting. And then that manufacturer stopped making the engine.So Jabiru designer Rodney Stiff began work on replacement. The party that loaned him the aircraft sent a flatbed trailer to recover it from a few states away. Proper cooling is key to engine longevity, and each engine/airframe combination will have unique cowl and cooling baffle needs to provide that cooling. behindpropellers. Where the Rotax uses independent coils, the Jabiru has two modified Honda coils feeding a pair of small distributors for the dual-ignition system. DESCRIPTION: The TBI-40-S, utilizes a spigot style round mounting system typically found on the Jabiru 3300 engine. Consider that a 100-hp engine on a 150-mph airframe gets far more cooling air passing through its cylinders than the same engine on an 80-mph airframe. Hi All. Which engine is the most reliable? However, I’ll argue the biggest factor in a reliable engine installation is keeping it cool. ... Amazing reliability of the 2200 engine! The electric fuel pumps required for the aftermarket system stopped pumping and the aircraft was severely damaged when it came down in trees. (Remember that the Rotax has a reduction gearbox.) Not exactly grumbly but not bumblebee, either.From inside, the 3300 moves the Jabiru smartly down the runway and results in very good climb considering the power loading. JEM3302-7 This Manual is a guide to correctly install the Jabiru 3300 engine into an airframe. 403 hours and climbing. Jabiru 3300 Overhaul Manual (202 pages) aircraft engines. flybymike wrote:For my retirement present to myself I'm contemplating the purchase of an LSA type, most of which seem to use the ubiquitous 912 Rotax, but some use the ostensibly more powerful Jabiru 3300. He wanted to build an airplane in 10th-grade woodshop but was asked to choose a smaller project. Pistons with holes? AP420CTF-SNR62H. “Honey, I have to fly to prevent an expensive engine repair.” When I sold my Sonex, the buyer requested that I continue to fly it until he could arrange for its pick-up. Propeller Manuals. Moisture degrades the electrical paths. You have entered an incorrect email address! This type of break-in procedure is more common on liquid cooled engines that can be broken in on the ground with less risk of overheating. And yet the clean-sheet Jabiru arrived into this world in 1992 as an air-cooled, opposed-piston, flat engine with a single, central crankshaft bolted directly to the propeller, a single central camshaft that operates two valves per cylinder through pushrods and rocker arms, and many other similarities to our supposedly outdated certified engines. Jabiru 3300 - Reassembly - Re-fitting The Cylinder Heads. No two engine installations on homebuilt aircraft are alike, and that is a significant factor in the reliability of any particular engine. Bill was loaned, for barnstorming purposes, an airplane equipped with an engine that required the cylinder heads be torqued and the valves adjusted at regular intervals. Some survive, others don’t. Engine Installation. Albeit a used one. Jabiru 3300 Related products. Continental lists the O-200’s dry weight as 170 pounds, which probably doesn’t include the charging or ignition systems. Jabiru Announces 3300 Pricing Program. The Sauer seem interesting but what about support and reliability? A constant thread throughout my articles is the human factor in homebuilding. We not only sell Jabiru … (81 kg.) In November 2014 the Australian Civil Aviation Safety Authority proposed restricting all Jabiru-powered aircraft to day-visual flight rules only, without passengers or solo students and within gliding distance of a safe place to land due to the engine line's safety record. Does anyone have any experience with a jabiru 3300 engine? Description The J230-D is the flagship LSA model in a long lineage of Jabiru aircraft. We have 4 Jabiru 3300 manuals available for free PDF download: Overhaul Manual, Maintenance Manual, Installation Manual . Home: CO15. Some of these conditions can be seen as inconveniences; a weak battery can be charged, corroded terminals can be sanded. The Jabiru engine has a TO for the “Top End” of 1,000hrs and for complete overhaul at 2,000hrs. Shortly thereafter he glided into a field without power and the airframe was totaled. Broken valve train? I define an engine failure as the failure of a component supplied by or specifically recommended by the engine manufacturer. The damage done, however, when dry piston rings are explosively compressed against corroding cylinder walls is immediate and cumulative. I have been considering a few engine options, but it looks as though the simplest and most cost effective solution is to go with a replacement Jabiru of the latest specification. There are some days when the best thing you can do for your engine is let it rest. The Jabiru 3300 is a lightweight four-stroke, horizontally opposed "flat-six" air-cooled aircraft engine produced by Jabiru Aircraft.The engines are direct drive and fitted with alternators, silencers, vacuum … And while my Rotax 912 time — probably 200 hours or more, but well spread out among a variety of airframes — isn’t terribly recent, I think I can still offer a few useful observations.Like most good engines, the Jabiru comes to life without fuss, thanks to a decent ignition system and well-considered jetting in the single Bing. A Continental O-200 has a 3.88-inch stroke, for comparison. Given a choice, who wouldn’t put the most reliable engine on their aircraft? Luck isn’t something aviators want to count on. Any engine that boasts a fleet of successful, flying installations can be deemed “reliable.”. Homebuilt Accidents: The Pilot’s Condition. Some, like Jabiru, are certified outside the United States. You may also have seen Jabiru’s 5100, an eight-cylinder derivative making 180 hp. Now to scam another ride in that Jabiru airplane, under the guise of continued research of course …. Take it one step further — as Continental and Lycoming (and Franklin and Pratt & Whitney and Wright) did — and bolt six cylinders to the case and you have the 3300, capable of 120 hp maximum and 107 continuous. Also note that I don't own any Jabiru products, engine or airframe soI have no stake in what is said. I have had lots of contact with the west coast USA rep Jabiru-pacific. For the ultimate in engine reliability we need to look to the soaring community. Trust and follow the engine manufacturer’s break-in instructions. It was awarded Plans Built Champion at AirVenture 2006. Fuel, particularly auto fuel, ages, loses its potency, and turns to varnish with a penchant for plugging small orifices in carburetors. It’s ironic that the maintenance we perform to keep our engines as reliable as possible can cause a failure, but it is not uncommon. )In all, the more I look at the Jabiru, the more impressed I become. Waiex N116YX, Jabiru 3300, Tail dragger, First flight, 3/16/2013. I did some research on the Jabiru 2200 engine, and found VERY mixed reports. So he can build an engine of pretty much any configuration: inline, V, opposed, W, X … so many possibilities. Fleet hours and units in service are a great yard-stick for reliability but every engine design begins with a single unit and a handful of hours. The high temperatures they witness after a 20 minute ground run at partial throttle convinces them those temperatures will soar under flight conditions, when full throttle is applied. In this airplane, the temps seemed very well controlled, with CHTs staying below the magic 380 degrees — though I don’t know if that number is magic for the Jabiru or not.Cruising is as simple as setting the rpm for the desired power and watching the temps. Failure to keep up with routine maintenance caused the valves to get so far out of adjustment that they weren’t closing enough to provide compression. The timing is fixed at 25 degrees. These lifters, removed from a certified engine, show serious signs of corrosion. This illustrates how displayed temperatures should not be taken as definitive. Those pistons provide a modest 8.0:1 compression ratio, which would be suitable for auto fuel if only Jabiru were confident of the go-juice’s quality; because it isn’t, the only recommended fuel is 100LL. The on-going reliability of a certified engine hinges on its correct installation, operation, and maintenance just as it does for a non-certified engine. As usual, Dan fails to mention critical issues beyond even complexity and cost of ownership. Our brand new CNC lathe is bolted down and working and a brand new CNC horizontal machining centre is on order and will be delivered at the end of March. Please note that links on older archive pages are often not active. With the low-end LSAs becoming modern darlings, Jabiru could be well placed. (Being air cooled, though, a clean inlet flow and appropriately valued exit area remain important. The Jabiru 3300 is a six-cylinder direct-drive air-cooled aircraft engine from Jabiru Aircraft Pty. Each crank throw is supported on both sides by a main bearing; a traditional aero engine has only a “flying web” between opposed cylinder pairs. The support structure is internal, so no bumps and lumps, nor do you see the typically grotty casting quality evident on your typical Lyconental. Bigger and simpler, too: No liquid cooling setup to deal with, one fewer carb (and no need to synchronize), and a pilot-friendly wet-sump oiling system that obviates the need for an external tank and the traditional “burping” required of the 912 to read the oil level properly. Many of the valvetrain components come from Honda, while the pistons are modified Australian-market GM pieces (the modification is to add a piston pin circlip to keep the pin from riding out and scoring the bore.) A certified engine on a certified aircraft fell victim to a certified mechanic who failed to tighten a hose clamp on an intake manifold. Your engine may operate in a different part of the green arc than your friend’s identical engine on an identical airframe but that is not an indication of trouble, it is the nature of engines and homebuilts. When I’m asked this question my answer is honest and straightforward: All of them are reliable, and none of them are reliable. Does anyone have any experience with a jabiru 3300 engine? The Jabiru, including an exhaust system, all electrics, and the carburetor, is said to weigh 178. I recall my flight instructor doing this with his Cessna 150 after the engine had been rebuilt. Check out the rest of Marc’s columns. In fact, Jabiru lists the 75% cruise consumption of the 3300 as 6.87 gph, which calculates out to a specific fuel consumption of 0.51 pounds per hour per horsepower. In theory, more main bearings the better, but there is a slight weight penalty and a supposed internal drag penalty as well. These bearing shells are, like several parts of the engine, automotive in origin. Although the Jabiru's engine sounded in rude health, I felt rusty after 2 months away from an aeroplane, so I proceeded to complete an hour of intense circuit practice (7, T/O's and landings) to get back in the groove. Even if you’re a certified-only kinda pilot, you should know more about Jabiru because one of its engines may well be under the cowling of that hot little light-sport aircraft you just bought.In yet another example of invention shooting out of Mother Necessity, Jabiru started as an airplane company and quickly found that the engine choices in the circa-60-hp class were limited to practically one. by Pete Twissell » Tue Oct 10, 2017 12:48 pm "cruise today was 100 kts at 27,500 rpm" The years of experience have given Jabiru engineers unique insight into ways to improve the durability and reliability of the engine design, making today’s Jabiru engines some of the most reliable engines ever produced for light aircraft. Waiex N116YX, Jabiru 3300, Tail dragger, First flight, 3/16/2013. Back to the crank design. A rubber coupling is used for securing the TBI and allows for 360 degree mounting. I had the good fortune to spend a day with a Jabiru 3300 in a Jabiru airframe recently. A carbureted Lycoming can do … No cause for the loss of power was determined. If you can’t think of what they may be, I have a story that will help. What is the most common cause of engine failure? Because we task engines with keeping us in the air where nature never intended us to be, engines seldom fail at a “good” time. If finish alone sold engines, the Jabiru would be flying off the shelves.Look further. Rotax 912ULS or Jabiru 3300. Any engine is prone to failure from human error. When you cross paths with someone complaining about the engine problems they’ve had, trace your eyes down the airframe it’s mated to. Their attempt to solve a perceived problem causes untold damage, and if the engine does fail it cements in their mind that they were correct all along. I will go out on a limb and say that most “high CHT” issues are related to cowling and cooling baffle installations, not the engine itself. Engine failure? The company has put that engine on the back burner as it concentrates on the smaller mills. It applies to airframe construction as well as the installation of a factory-fresh engine. We must accept that no engine is completely reliable and that we, as installers, operators, and maintainers, bear much of the responsibility for this. The 2200 in my J160 has just had to be written off due to a sequence of failures which appear to relate to an accident prior to me taking ownership. Ltd. (Australia). ENGINE DETAILS: JABIRU 3300. They are usually very reliable. He was a regional sales manager for the company that manufactured the bikes and therefore had quick access to service as well as a detailed follow-up on the problem, which was a connecting rod that had not been properly torqued. To keep costs down, Jabiru uses off-the-shelf automotive parts where it can. Every engine has operating limitations that define its maximum and minimum operating temperatures and pressures. The piston-powered community, however, has posted engine failures for every engine that has ever been bolted to an airframe. 10-13-2010, 02:08 PM. Moisture slips in through the carburetor, exhaust pipes, and engine breather, goading corrosion to form on all the finely machined ferrous surfaces in the engine. This full throttle break-in is done in the air, not on the ground, so the engine cools properly. marcusofcotton. Inside the carburetor throat is a piston [called a slide] that descends to block air flow. Jabiru 3300 Rotax 912 (single unit) Rotec R2800 Rotec R3600 Others 90-150 HP. The likelihood our bikes were neighbors on the assembly line is extremely high. Got motors on your mind? By fixing a non-problem, a failure mode was introduced that the engine, as designed, would have never experienced. At a minimum the cylinder walls are micro-scored. (Wow, this aircraft-owning stuff isn’t for the casual observer.) Motor Head #16: Jabiru — A New Engine That’s Not All That... United, Archer Partner On Short-Haul Electric Aircraft, Re.Invent Air Mobility Initiative Participants Selected, How A Split Second Wrong Decision Caused the Kobe Bryant Fatal…, How This Illustration Fueled My Obsession With The Bell X-1, EAA Posts Initial AirVenture 2021 Health And Safety Measures, Sriwijaya Air Prelim Highlights Thrust Imbalance, FAA Investigating Latest SpaceX Starship Test, Rolls-Royce Conducts Unblended SAF Tests On BizJet Engine, Report Calls For Multi-Pathway Approach To Mitigating Aviation Lead, Avionics: Down For 2020 But Showing Signs of Recovery, Wireless Utility Controls Jammed GPS Near Airport, uAvionix Launches pingStation 2 ADS-B Receiver. Comes to that, the Jabiru’s diminutive valve covers in some ways remind me of Continental’s technically superior yet ill-fated Tiara series’. It could be you! That’s great, but the trick is the needle attached to the slide. (Still, carburetor heat is a recommended airframe addition. The high gloss urethane surface shows off the quality craftsmanship and attention to detail.
