				I recently became aware of what appears to be a developing  and 
 potentially significant problem. Slick (Unison industries) has issued 2 
 service bulletins for their Mags and LASAR ignitions. depending upon 
 serial number applicability,  they require recurrent inspections (at)  5 
 hours of ops and then at 15-20  hour intervals.  There has been some 
 chatter on VAF about  this,  however the problem seems to be bigger 
 than  reported, with  several magnetos failing  at relatively short  
 time in service durations.  I recently heard of an RV-10 experiencing a 
 mag failure (at) 50 hours . With nearly 150 RV-10's flying I'm curious as 
 to the extent this problem has been seen in the community.  What are 
 people experiencing/hearing?

				I checked my s/n this weekend (didn't do an internal inspection of
 the mag) and found that mine is before the S/N's listed, so I breathed
 a huge sigh of relief.  But, I just heard of our pal Wayne up in
 Alaska...y'all know him, and he hasn't had THAT many hours on his
 plane, but I guess his mag was one affected and he just had it
 go out up there....sounds like it was just a wreck inside.
 I don't know what the heck Unison did...would be nice to know the
 history, but it sure sounds like if you're in that s/n range, it's
 a disaster waiting to happen....so I'd keep close tabs on it.

				The cap failed on my Bendix mag (at) 50 hours, could be a product wide problem.

				I knew nothing about this SB until Deems' email - thanks for the heads
 up!!
 
 Since my engine ex Vans was shipped mid last year, I expect that I will
 have two problematic mags that need treatment.  With luck and since they
 have not been used, I may be able to have them replaced under warranty.
 
 I have never pulled a mag apart before and have little clue about what
 may be involved to perform these inspections.  Can anyone shed any light
 on basic mag maintenance, or provide a pointer to the relevant Slick
 docs (eg L1363)?
 
 I thought I was almost finished, but with 2 Vans SBs, one on the
 Injector servo and now this, I doubt I will ever get there and wonder
 what I've gotten myself into.

				If I read the SB's correctly (that's a bif IF). the 1st one which 
 contains the most restrictive and more frequent inspection cycles has a 
 narrower serial number range. The implication is that this issue is 
 related to more recent production (say within the last couple of years. 
 However, the second SB, essentially broadens the serial number range, 
 but makes the inspection cycle somewhat less onerous for the earlier 
 produced units. I didn't know of Wayne's incident, but that's the 2n'd 
 RV-10 with a mag failure that I've heard of with relatively few hours on 
 the mag/s

				I'm hoping the Kelly McMullen ,  John Cox, or Pat Thysen will chime in 
 here on this, and shed some A&P insight. Some of the other lists have 
 chatter that's pretty critical towards Unison.

				Ron,
 	Now I feel awful when I goofed you about "almost being done."
 Sorry, you will get there we have no doubts.
 	I asked someone from the RV list to cross post his info on
 inspection of his mags. Worth reading.

				One of the things to note is that the 0409xxxx series seem to be the retard
 breaker mags and the 0408xxxx seem to be the non retard breaker mags.

				Yeah, and lucky me, after seeing your post I went back digging
 for the SB's and saw the 2nd one, which DOES incorporate my
 mag.  The nice thing is, I have over 250 hours, which puts
 me at a less frequent inspection timing.....but it still doesn't
 give me lots of warm fuzzies.  The real big thing that DOES
 give me warm fuzzies is that I have a Lightspeed unit, so even
 if my mag fails, my LSE should be working good....but hopefully
 the mag timing isn't so far off if the mag fails that it
 makes the engine run bad.

				I also have a Lightspeed unit on the right, (top) side, and when my mag failed, I experienced no noticeable difference in engine operation. Until the next preflight run!

  I recently became aware of what appears to be a developing  and potentially significant problem. Slick (Unison industries) has issued 2 service bulletins for their Mags and LASAR ignitions. depending upon serial number applicability,  they require recurrent inspections (at)  5 hours of ops and then at 15-20  hour intervals.  There has been some chatter on VAF about  this,  however the problem seems to be bigger than  reported, with  several magnetos failing  at relatively short  time in service durations.  I recently heard of an RV-10 experiencing a mag failure (at) 50 hours . With nearly 150 RV-10's flying I'm curious as to the extent this problem has been seen in the community.  What are people experiencing/hearing?

				Thought I would chime in on the Slick mag issue  since I'm the recipient of one of their failures. On June 21st I left TX  starting on a flying trip up to and through Alaska that ended this last Sunday  July 6th back in TX. When I was in Anchorage getting ready to head  to Ketchican I had my right mag fail. I don't mean run rough it completely  drop off the earth and went to mag heaven. I don't know the technical  term but basically the lobe on the cam in the mag that lifts  the points to allow them to open was completely worn off, they call it the  breaker point cam. I'm sure all of you already know this but it's Lycoming  Service Bulletin 583 & 584 dated June 3rd.
   
  I have the Lasar system so I had that plus the left  mag remaining so if I had been where there was no repair station I still had  some options left to me. At the time of failure I had about 165 hours on the  engine.
   
  I was lucky and found a great shop on the  field in Anchorage to work on my problem, Aero Twin. These guys were probably  this best group I've ever worked with. I was flying with 12 other planes that  had to go on without me and the shop was trying their damndest to get me  back in the air so I could catch up with the group. They even worked through  their lunch hour to get me back in the air. Great bunch of guys. 
   
  My first problem was finding a mag, since as all of  you know that electronic ignition isn't widely used and available for general  aviation. So the shop manager was able to talk to Joe at Unison and he over  nighted me a new mag. The mag that he sent me is under their same service  bulletin as the one that was being replace, since they really don't have a know  fix yet, that I'm aware of. So I've just traded a bad problem for a known  problem. Sue at Aero Sport told me that probably all Slick mags from 2004 on  are affected. Isn't this amazing, they've been making these parts forever  and they find someone who will make them for $3 less and we end up with their  mess because of this.
   
  My second problem came when the shop didn't have  the Lasar timing tool. I called Unison and he didn't have any available to send  me with the mag and I then called Aero Sport Power, Sue, who I had been  communicating with on this, and she had one but they had a Canadian holiday this  next day and couldn't get it to me. I ended up calling my friend Steve Gross who  hangars his RV6 in my hangar, and he overnighted me my timing tool. I thought  this was kind of a funny statement, but maybe not, Joe from Unison said I should  always carry my timing tool with me in the plane. Boy that's confidence don't  you think! Oh well. 
   
  Anyway I was able to get back up and running and  was able to catch up with the group in Ketchican, so I guess the saying is all's  well that ends well. I guess for now :>}
   
  If any of you have any interest in seeing some of  the Alaskan photos that we took I created a blog for my grandkids where I made a  daily  posting               
   
  triptoalaska2008.blogspot.com     
   
   Actually with the lack of WIFI at one  location and this mag failure I got behind a little but I'm trying to get  it caught back up know. At the very bottom of the blog is a daily  folder of all the photos we took. There is some pretty interesting  country side in Alaska for those of you who haven't been there.

       I recently  became aware of what appears to be a developing  and  
       potentially significant problem. Slick  (Unison industries) has issued 2 
       service  bulletins for their Mags and LASAR ignitions. depending upon  
       serial number applicability,  they  require recurrent inspections (at)  5 
       hours  of ops and then at 15-20  hour intervals.  There has been some  
       chatter on VAF about  this,   however the problem seems to be bigger 
        than  reported, with  several magnetos failing  at relatively  short  
       time in service durations.   I recently heard of an RV-10 experiencing a 
        mag failure (at) 50 hours . With nearly 150 RV-10's flying I'm curious as  
       to the extent this problem has been seen in  the community.  What are 
       people  experiencing/hearing?

				A Bendix mag is very different than a Slick and generally is very
 reliable. Slick has had its ups and downs. Mainly use of forms of
 plastic that aren't as heat resistant as needed.

				Makes one want to specify a Bendix mag or two when buying from one of
 our favorite specialty engine shops, eh?

				That's what I thought to, until I read this last post, describing how 
 the points failed. It described my failure exactly.

				Guys:
   
  As a reminder, the corrected copy of the SB contains the applicable serial  numbers that are affected.

 Yeah, and    lucky me, after seeing your post I went back digging
 for the SB's and saw    the 2nd one, which DOES incorporate my
 mag.  The nice thing is, I have    over 250 hours, which puts
 me at a less frequent inspection timing.....but    it still doesn't
 give me lots of warm fuzzies.  The real big thing    that DOES
 give me warm fuzzies is that I have a Lightspeed unit, so    even
 if my mag fails, my LSE should be working good....but hopefully
 the    mag timing isn't so far off if the mag fails that it
 makes the engine run    bad.

  If I read the SB's    correctly (that's a bif IF). the 1st one which 
  contains the most    restrictive and more frequent inspection cycles has a 
  narrower serial    number range. The implication is that this issue is 
  related to more    recent production (say within the last couple of years. 
  However, the    second SB, essentially broadens the serial number range, 
  but makes    the inspection cycle somewhat less onerous for the earlier 
  produced    units. I didn't know of Wayne's incident, but that's the 2n'd 
  RV-10    with a mag failure that I've heard of with relatively few hours on 
     the mag/s

				I expect any new engine or rebuilt engine with  new mags will be affected by the SB.  I bought my engine from Vans mid '07  and I too have dud mags.  I contacted Unison to see if I could have them  replaced under warranty - mine are brand new never run.  The simple issue  is that they have NO solution and have nothing better to replace them  with.  Given our deeeep south location, there are not many options with  alternate brush/cam suppliers, so I have no choice other than inspections every  15-20 hrs until 50hrs per the SB.  I just hope the mags are not difficult  to remove - I am having nightmares about dropping a support bracket or nut into  the engine accessory case already.
   
  cheers,
  Ron
