I hope that Matt will allow me a little bit of advertising!
We have known for a number of years that the original Russian coils are failing and indeed in Europe have had several forced landings as result of this. We consulted with a UK company who overhaul magnetos for historic racing cars who felt that the main problem was that the capacitor, an important part of the coil sits inside the coil of hotwire and over a period of time through a combination of age and heat will slowly degrade until it fails, and even if it is only in one magneto, the symptoms are a total, if momentary stoppage. Over a period of time this will get worse until the engine will stop for a significant period.
Working with this company we developed, some 30 months ago, a new coil with a high-technology Panasonic capacitor bonded to the outside of the coil, as well as improvements to the materials used. These have been very successful, but this small company could not produce sufficient coils for us. Then, UK CAA realise that we were selling coils, but without any paperwork – this being deliberate. Of course we do not have the freedoms that you lucky guys have in the USA, and they began grounding various perfectly airworthy aircraft belonging to our customers. And at the same time, they asked us (quite nicely) if we could make a formal application to certify the coils.
I had absolutely no idea of the amount of bureaucracy and testing that this would involve – but I suspect it would be the same if one wanted to get full certification for a new coil with the FAA! Before this, we had also decided to investigate a larger capacity manufacturing unit, and came to an agreement with AYC Ltd in China. They are one of the largest oil manufacturers in the world; making over 1 million a year, ranging from lawnmowers up to Ferrari cars. Although we represent incredibly small business in their terms, they were extremely enthusiastic about getting into the aviation business. We have found them superb partners; technically incredibly capable and very responsive. So it has been the AYC coils that went through this testing process for certification, and through the use of much better materials, these coils give a spark that is 15% to 20% stronger than a perfect Russian coil, and we now have them in full production.
Importantly we now have full certification from UK CAA and EASA who control all aviation in Europe, which must be an indication of quality!
Please contact us if you need any more information about these coils.
