Hopefully they will take care of the people out there that have spent money on the bad plugs and replace them with the new design. The sure sign of a plug being faulty is a crack or multiple cracks on its porcelain cover. Champion Aerospace designs and manufactures Champion-brand piston-engine ignition components for both OEM and aftermarket for general aviation aircraft applications. The silicon carbide resistor is a high voltage device and cannot be tested with a standard ohm meter. Aircraft engine repairs are some of the most critical and technical repairs in the world of piston engines, and the right tools are as important as experience. With good performance from the plugs and excellent service from the company, I’ll be buying them going forward. 1983 Saratoga Turbo, Lycoming TSIO-540-S1AD engine. Shop Champion spark plugs for automotive, lawn and garden and marine applications on ChampionIridiumPlugs.com - an authorized Champion Auto Parts dealer. The older-design plugs have a straight screwdriver slot machined into the metal contact, while the newer-design plugs do not. On several plugs the resistive element was completely OPEN, meaning the magneto has to arc across the resistor – do a YouTube search for Max Nerheim Champion, and you will see a short video. 1-864-843-5469 Fax Line i get hot start performance now due to the electronic ignition on my fuel injected Lyc 4 banger. read into the trends and the company behavior…. In the DC-3 I fly every day, we have had the same experience and we have quite a few plugs to check to find one that’s bad. additionally, the electronic ignition driven plugs all have reduced life. Just today I found 3 out of 8 that were bad with the resistance check. They should have adopted Auburns design immediately. SKU #RN13LYC. I have electronic ignition on my Mooney 201, it powers the bottom plugs, regular magneto powered top plugs. Their field reps ratcheted up their public relations campaign claiming that the ohmeter check was meaningless, and insisting that Champion spark plugs didn’t have a resistance problem that affected the performance of their plugs. who ever inspected it didn’t care. I personally, have run a Cessna 182 from the time the engine was new to TBO (1700 hrs) on the same set of Champion fine wires. If I’m right, this is very good news indeed for users of Champion aviation spark plugs. To draw a recent analogy from the automotive world: A lot of people drove GM cars with faulty ignitions and never had a problem; but that doesn’t mean people weren’t killed and a recall wasn’t necessary. You mention you first noticed this in 2008 – what changed in 2008 ? To do this successfully, they need to be covered in thick insulation to prevent high voltages jumping off the wire before it reaches the spark plug and a rubber boot at each end. A typical low voltage ohm meter (or the Tempest AT-5k meter which relies on a low voltage circuit) can help identify suspect plugs. The spit really hit the fan when Champion’s primary competitor in the aviation spark plug space, Aero Accessories, Inc., launched a marketing campaign to promote sales of its Tempest-brand aviation spark plugs by highlighting the resistance issue. CHAMPION AVIATION SPARK PLUG TESTERS 110V AND 220V Designed to clean and test all 14mm & 18mm massive and fine-wire electrode aviation sparkplugs. I believe that Champion had to change because the Tempest advertising barrage got the herd to scampering. Q: What do you call an airplane with Slick magnetos and harness and Champion plugs? Aircraft ownership and maintenance, Mike Busch, Opinion, ChampionChampion AerospaceGA advocacygeneral aviationmaintenanceohmmeterownershippreventive maintenancereliabilityresistanceresistorspark plugspark plugs. New Tempest-brand plugs typically measure about 2,500 ohms. Champion offers traditional spark gap technology in legacy products, but has transitioned to pioneering designs solely utilizing solid-state technology incorporating our patented multi-voltage “Spider Switch” or new (patent pending) Solid State Spark Gap (S3G) design to maximize reliability, efficiency and capability while minimizing weight. If the damaged mag was replaced without replacing the spark plug, the new mag would be damaged in short order. He called Champion (BTW these are fine wire plugs too) and they told him to send them in. Champion Aerospace designs and manufactures Champion-brand piston-engine ignition components for both OEM and aftermarket for general aviation aircraft applications. An Ohm meter, which is part of a multimeter, can only check a spark plug for a short circuit or a breakdown of insulation resistance. https://www.youtube.com/watch?v=DERIHonZT-k I bought (8) Champion RJ12YC on Ebay, and they all measured 100k-300k resistance. Also, he sent detailed test reports of the plugs I returned, along with pics of the test process and procedure (the plugs passed on their system). Our goal is to be the preferred supplier of aerospace ignition systems and airframe power components. who ever made it didn’t care. understood and my best wishes as well, of course. Every spark plug manufactured has built-in design advantages that assure longer life and greater reliability. Last fall, during a plug “bomb” test, two of the plugs didn’t pass. Sometime in late 2014, it appears that Champion very quietly changed the internal design of their spark plugs to use a sealed, fired-in resistor element that appears to be quite similar to the design of the Tempest/Autolite plug. I tested them first on the Tempest gizmo ( it is fairly quick and accurate) then because of the red light (failing), tested for the Ohms value.They were all very high. In the face of both overwhelming technical evidence from the field that their spark plugs had a resistor problem, and a virtual blitzkrieg from their principal competitor that was starting to erode their dominant market share, Champion began having some self-doubts. Military Specification MIL-S-7886 provides guidance for aviation spark plug manufacturers. Champion can provide Industry Certification compliant ignition system hardware for hazardous environment requirements (i.e. The OHM Meter check is simple, readily available, and amazingly accurate in finding misfiring plugs. I suppose grief is a very personal thing, and everyone deals with it differently. Champion management tried to cover it up by lying… so we won’t be purchasing their plugs again – even with the improved design. I had already swapped out for Tempest plugs after experiencing poor starting problems. These tools are designed to do a specific function and help make the removal and replacement process easier and less time consuming. Doing it right takes more than desire, it takes good set up tools. Examination revealed one of the engine’s eight REM38E spark plugs was not firing. With a multimeter, it takes just a few minutes to measure the resistance of each plug wire. A brief talk about checking shielded aircraft spark plugs with suggestions. 06-17-2020 - Champion Aerospace awarded Elite Supplier Status from Lockheed Martin, 05-10-2018 - Champion Aerospace announces AS9100 Rev D Certification, 1230 Old Norris Road Champion Spark Plug Resistor Test. New Tempest (formerly Unison-Autolite) will measure 1000 OHMS. A spark plug is a device installed at the top of an engine cylinder that generates sparks at the tip of its electrode when a high voltage is applied across its terminal ends, thus igniting the compressed air-fuel mixture in the cylinder. I just bought a box of Tempest plugs from AC Spruce. Now then, Champion has been building spark plugs for a while, a long while. when it comes to resistor plugs the proof is in the measuring, I own a mooney M20F EXE in and I have experimented two engine faillure caused probably for this reason , and have the second with brand new cylinder with about 15 hrs tt ,this is probably scrap at this time, The temperature have grow up to 750 in about 50 -70 second max Thanks Mike for the article. As I write this, it’s still too early to tell whether Champion’s quiet resistor redesign will cure the drifting resistance problem, but my best guess is that it will. I shared my findings with him on my 2 year old Champion plugs that I had pulled out of my Mooney, which all showed the high resistance and some internal corrosion. Talking to champion they said they haven’t changed their plugs in over 20 years. Champion should provide us with good replacement resistors for our perfectly good spark plugs. Champion Aerospace designs and manufactures a full range of aerospace ignition leads for turbine engine applications. Well, you first have to know what does a bad spark plug look like before knowing how to check spark plugs. I’m not putting those Champions in anything !! I’ve done a number of lean-of-peak mag checks and all is well. Probably nothing wrong with the Tempest plugs, I have run some in my other plane, and they also seem fine. The spit really hit the fan when Champion’s primary competitor in the aviation spark plug space, Aero Accessories, Inc., launched a marketing campaign to promote sales of its Tempest-brand aviation spark plugs by highlighting the resistance issue. i only report my data so that others may benefit from my limited data point. Results. So far all looks good. How to Check Spark Plugs: A Detailed Analysis. Here, for example, is a set of 12 Champion plugs removed for cleaning and gapping from a Cirrus SR22 by a shop in South Florida: Notice that only two of these 12 plugs measured less than 5K ohms, and one of those had to be rejected because its nose core insulator was cracked (a separate issue affecting only Champion fine-wire spark plugs, and unrelated to the resistor issue that affected all Champion plugs). Our broad range of plugs provide performance, fuel economy, durability and reliability. The S3G is a newly introduced concept that is virtually a “plug and play” device into legacy or new applications requiring radiation-free assemblies. I send you a picture, ©2016 Aircraft Owners and Pilots Association, По какой-то причине пресса незаслуженно очернила микрозаймы в глазах общественного мнения. I have used Aircraft Magneto Service (aka Cliff Orcutt) exclusively for mag rebuilds during the same period and had great results using his mags and 5k testing techniques. The Champion Aerospace website makes no mention of any recent design changes or product improvements. (Aero Accessories acquired the Autolite line of aviation spark plugs from Unison Industries in 2010, an re-branded them under its Tempest brand.) I was floored! As the plug ages, values below 5000 ohms are acceptable. The resistance of a plug with SAC-9 suppressors are capable of combating typical RFI, but cannot be accurately measured with typical low voltage ohmmeters. Every spark plug manufactured has built-in design advantages that assure longer life and greater reliability. Adding a resistor to the plug also raised the minimum firing voltage for a given electrode gap. Even had a 400-hour warranty. Replace any plug above 5000 OHMS.
