 Hello again Doug,

  

 Thanks for your input, but I think you're missing some key points  here.

  

 In regard you your points, in order, here's what you are  missing:

  

 #1, these engines with these bad coils were also sold in the USA. Why no  dealer letter here? I had never heard of this issue prior to being pointed to  the French Jabiru dealer's letter by a Europa owner. I have been told that  this issue was discussed in "Jabbachat" in 2002 or 2003, 2-3 years before I  bought my engine. So, I'm supposed to wade through hundreds of posts on their  chat forum from 5 years ago to find out about this potential problem? Isn't that  what Service Bulletins are for?

  

 #2, No, I clearly did not have "Leading GX" coils, as I've said repeatedly.  Again, mine did not have that notation. However, it has come to my attention  from another Jab owner who has learned that Jabiru sourced a batch of  cheap, Chinese knock-off coils that came after the "Leading GX" and  "Leading GC" coils, but before the TEK coils currently in use. These too,  apparently had a high failure rate. I think this is what came on my engine,  although I'm still trying to verify that as fact. I also think this is the  "black glossy" coil that is referred to in the French Jabiru dealer letter.  

  

 #3 & #4, I'm aware of that. However, that still does not explain why  the first coil was not covered under my warranty. It also does not explain  why my current coils have been running for 90 and 120 hours respectively with no  problems. If I had a problem with coil cooling in my set up it stands to reason  that the current coils would have also failed due to heat, doesn't it? That has  not occurred. I followed the Jabiru installation guidelines to the letter,  including verifying the installation of phenolic washers behind the coils,  which were installed at the factory and were installed behind the  replacement coils I purchased. I also installed the cooling tubes  to direct air onto the coils as directed by Jabiru in their  installation guide. Nothing in my cooling set up has changed since before I  first ran the engine, except for the installation of a larger oil cooler and  that is not anywhere near the coils. Thus, through simple logic you can  deduce that heat was not the issue that caused my original coils to fail. If it  were, subsequent coils installed would have also failed. Of course,  now we will never know because my coils were destroyed by the dealer and were  never sent to Jabiru for inspection. All I have to rely on is pictures  now.

  

 #5, I did that immediately to see what the problem was when the engine  began to run rough and lost RPM's. Turning off the bad ignition did not help the  rough running or the RPM drop. Think about how the engine runs on one  side doing a mag check. That is what it was like, only at higher  RPM's. Replacing the coil with a good one fixed the problem and my engine  has been running like a sewing machine ever since I purchased the TEK coils and  installed them at 0 hours and 30 hours respectively. 

  

 #6, I would imagine that anyone who has been flying a Jabiru  engine for 4 years that came with any of these  known bad  coils has already replaced them. My concern is for the guy who has an engine  that was produced along about the same time as mine that potentially  has these coils installed that has not yet flown. There are bound  to be some of those out there. If you were one of these people, would you not  want to know that you have coils on your engine that have a high  probability to fail on your first flight? I sure would.

  

 As to whether or not Jabiru is covering things up, I have no way of knowing  because they will not communicate with me directly. I have not said that Jabiru  is covering things up at all. Andy told me a few days ago that  he destroyed and discarded the coils I sent back to him for  warranty replacement, apparently at the direction of Jabiru. I am told this was  to save shipping costs. Jabiru then proceeds to tell Andy that they are  certain my coils failed due to heat exposure without even testing them and  as such, refuses to honor my warranty. Despite Andy's insistence otherwise,  Jabiru is holding firm, with absolutely no evidence to back up their  claim. You are free to draw your own conclusions as to what is happening  here. I am left wondering exactly how Jabiru determines whether or not to  warranty a coil if they don't inspect them? They clearly don't want them sent  back to the factory for inspection and evaluation. Exactly how have they  determined that mine failed due to heat exposure? They've not seen my setup, the  temps it runs at, nor have they inspected my coils.  Perhaps they use  the "Magic 8-Ball" method?

  

 As Dave G. says, Jabiru can avoid all the bad PR by replacing my coils or,  preferably, by providing me with a refund for the replacements I purchased,  even at this late date. I paid for that warranty with the price of my engine and  I am being denied coverage based on absolutely no evidence that my  original coils were killed from heat. Jabiru can and should issue a letter,  or preferably a Service Bulletin, letting folks know that there might be a  few of these coils floating around out there, how to identify them, and  that they are potentially hazardous. Only Jabiru knows for sure how many of  them there are and they aren't talking. That would be the smart thing to  do, don't you think? Those coils, if discovered, should also be replaced  under warranty. Given the high failure rate that the Chinese coils seem to have  had, it stands to reason that it is in Jabiru's best interests to get them off  all engines ASAP. I think this is a reasonable approach and one that I've seen  Rotax and other engine manufacturers take on numerous issues that weren't nearly  as serious as ignition failure due to known bad coils. The gist of what I'm  saying is Jabiru has not acted in a professional manner regarding these coils.  Flying experimentals requires accepting a certain amount of risk, I'll grant you  that. However, managing that risk requires that manufacturers notify their  customers of potential problems so that they can be dealt with accordingly.  Apparently, that has not happened with us American redheaded stepchildren Jabiru  owners. It's all about professionalism, or lack thereof, in my eyes.

  

 BTW, thanks for keeping the discussion polite and on topic.

The absence of input from us as John’s dealer makes it look like we’re doing nothing, which isn’t true! I’ve put John’s case (again) to Jabiru and have at least received a read-receipt for the email, so the issue is in their hands, as to a warranty reimbursement for the coils and oil pressure sender which were faulty. Personally, I don’t think there’s going to be an argument based on the facts given so I expect to let John know as soon as I have confirmation.  

   

The next point I want to clarify was the action taken at the time we knew about the Leading GX coils from Jabiru. Each of the three USA dealers had a number of ‘affected’ engines, and we were notified by Jabiru with lists of serial numbers. Jabiru wanted dealers to contact their customers direct and resolve the issues, which is what we did. I know that Jabiru USA sent a letter to their relevant customers and OEMs, and as the numbers of engines for us was only about a dozen, we called everyone, told them about the problem, discussed the situation in depth (so they could decide what to do: fly or not fly, etc), and let them know when they could expect replacements and how to return the old coils. So, Jabiru decided (rightly or wrongly) to deal with the situation through their Agents for a finite number of known customers rather than publishing a Service Bulletin. Jabiru knew they had an issue, were confident of the range of affected engines, and decided on a course of action. There was little point in us sending potentially faulty coils back to the other side of the world, so we were instructed to destroy the coils to ensure they couldn’t be re-sold. When John’s coils came back, we cut off the leads and binned them.  

Other countries have different legislative frameworks for airworthiness of experimental aircraft, and so dealers in France and UK (probably others too) were bound to involve their respective governing bodies who in turn decided that a country-specific service letter was appropriate. Not so in USA; we as dealers felt we had the situation under complete control.  

   

I have admitted both here and to John directly that I should have done better to push his warranty case but after the first rejection by Jabiru (in a phone call to their Principal) I let it slip. John had fixed the problem, admittedly at his expense and was obviously pleased with the performance of his engine. The recent re-surfacing of the issue of coils here, together with John’s photos of (clearly) different pattern coils than those currently sold, has left a few questions which I’ve asked Jabiru to answer. Honestly, there’s no cover-up in my view; I think Jabiru made the wrong warranty decision initially about John’s coils and then I failed to attend to it by chasing again for resolution. For me, the issue as to whether some ‘known/faulty’ coils got into engines after the Leading GX phase is of course an important one and it needs to be investigated and answered and again, I have sought these answers. I certainly haven’t experienced any such issues with engines we’ve sold, except of course in John’s isolated case, and I haven’t heard of others from any other dealership; believe me, we’d have told each other had this come to light.  

   

I hope this fills-in some gaps so we see a few less sparks flying (pun totally intended). I’ll keep the readership informed about anything relevant.

Hey guys,  I have a question:



Isn't their a certified version of the Jab engine being used in Aussie

land.  I was told long ago that the engine had been certified Down Under

and was used in a lot of their flight schools as a trainer.  If that is the

case, does Jabiru have to issue AD's on those engines just as the FAA

requires on certified engines here in the USA?  I wonder if any of those

shiny black coils were ever put on the certified version of the Jabiru

engine?



Just a thought. (Before someone jumps on me I realize that our engines here

in the USA are not the certified ones but I was also told that the Parts

etc for the engines are basically the same)

Rob,



Yes, there is a 'type certified' 2200 engine used in Jabiru's

Genearl-Aviation version of it's trainer, but the 3300 engine does not (as

far as I know) carry this certification. Also, the certification is under

the Aussie CASA (not FAA) requirements, so there's not a 100% compliance

with (say) FAA/FAR Part 23.



I'm sure there would have been some potentially faulty coils fitted to a few

of their factory aircraft and I'm equally sure they dealt with it under the

requirements of their certification.

Hello Andy,

    

   Received this email...not quite sure what this is all about.

    

   Was it sent by mistake?

    

   Please do not hesitate to contact me...very interested in the present status of territories of the US distributors...I have heard many conflicting suggestions.

John, 

 As often happens in these types of discussions, some very key information  that was not previously known comes to light.  We did not know that Andy  had communicated with you.  And I am a little stunned by that  information.

  

 Because of what you say in the paragraph below and assuming it is  true, then In my mind there is a simple claim and answer.  Because  Andy accepted the coils and then destroyed them, he owes you two new  coils. Or the money for them. And it should be your choice.  Period.  If he had sent them back to you, that would be another  matter.

  

 Jabiru factory has nothing to do with it.   They are in  Australia, Andy is not.   The coils belonged to you , they dont exist  now, so the person who made them disappear is on the hook.  In my opinion,  he should fix it....NOW!

  

 I chose not to say more about what I am thinking and feeling about the  forgoing. 

  

 Now, as to the problems with other people having the coils,  I would  disagree with you.  However, if they have not opperated their engine in 4  years and are about to do a first flight, they need to send it back to the  dealer for inspection.....at their expense.  Since you were a Rotax dealer,  you know what happens to a 912 that sits that long.  And you also know the  Rotax warrantee would have expired three years ago, even with the  extension!    

  

 Does it deserve some kind of Service Bulletin?   I dont really  know.  Again, it depends on how many engines are out there.  Again, I  would be surprised if it is more than a handful.  But if I were a Jabiru  dealer, I would want to track down every customer who got an engine that might  have been affected.  (Hint, Hint!)

Andy, 

 I replied to an email from John before reading yours, so I will say to you  what I said to him.  Remember this is my OPINION, but....

  

 You personally owe him either the coils back, new coils or the money he  paid for coils.  Since the coils have been destroyed, you either owe new  coils or the money.  And it should be his choice.

  

 On a better note, I am personally pleased that you guys did INDIVIDUALLY  follow up on any questionable coils on those early engines.  You didnt let  me down on that issue!!!

Personally, I donâ€™t think thereâ€™s going to be an argument based on the facts    given so I expect to let John know as soon as I have    confirmation.   

    

The next point I want    to clarify was the action taken at the time we knew about the Leading GX coils    from Jabiru. Each of the three USA dealers had a number    of â€˜affectedâ€™ engines, and we were notified by Jabiru with lists of serial    numbers. Jabiru wanted dealers to contact their customers direct and resolve    the issues, which is what we did. I know that Jabiru    USA sent a letter to    their relevant customers and OEMs, and as the numbers of engines for us was    only about a dozen, we called everyone, told them about the problem, discussed    the situation in depth (so they could decide what to do: fly or not fly, etc),    and let them know when they could expect replacements and how to return the    old coils. So, Jabiru decided (rightly or wrongly) to deal with the situation    through their Agents for a finite number of known customers rather than    publishing a Service Bulletin. Jabiru knew they had an issue, were confident    of the range of affected engines, and decided on a course of action. There was    little point in us sending potentially faulty coils back to the other side of    the world, so we were instructed to destroy the coils to ensure they couldnâ€™t    be re-sold. When Johnâ€™s coils came back, we cut off the leads and binned    them.   

Other countries have    different legislative frameworks for airworthiness of experimental aircraft,    and so dealers in France and    UK (probably others    too) were bound to involve their respective governing bodies who in turn    decided that a country-specific service letter was appropriate. Not so in    USA; we as dealers felt    we had the situation under complete control.   

    

I have admitted both    here and to John directly that I should have done better to push his warranty    case but after the first rejection by Jabiru (in a phone call to their    Principal) I let it slip. John had fixed the problem, admittedly at his    expense and was obviously pleased with the performance of his engine. The    recent re-surfacing of the issue of coils here, together with Johnâ€™s photos of    (clearly) different pattern coils than those currently sold, has left a few    questions which Iâ€™ve asked Jabiru to answer. Honestly, thereâ€™s no cover-up in    my view; I think Jabiru made the wrong warranty decision initially about    Johnâ€™s coils and then I failed to attend to it by chasing again for    resolution. For me, the issue as to whether some â€˜known/faultyâ€™ coils got into    engines after the Leading GX phase is of course an important one and it needs    to be investigated and answered and again, I have sought these answers. I    certainly havenâ€™t experienced any such issues with engines weâ€™ve sold, except    of course in Johnâ€™s isolated case, and I havenâ€™t heard of others from any    other dealership; believe me, weâ€™d have told each other had this come to    light
