Slick Mag SB1-19

I don't have or work on slick mags, however I know some of you do. My FAA PMI just sent me this new service bulletin which may be of some interest to some of you.

slick was talking about it at Oshkosh, Impulse coupling pins. Ever since Champion took over slick's quality control in early 2000's, they have had a lot of problems. Bendix has the same problems. The also just had a SB for the rotor and a monel contact coming loose from just over a year ago...and there was the points and carbon brush back in '08 ish...
