Anyone running Bendix mags on an IO540D4A5. Im switching away from the Slicks to the Bendix S-20 or S-200 mags. Any starting issues with them. Im not ready to go to the electronic mags yet. Maybe down the road.
Reason for the change. With all the comments on the forum made about Slick impulse mag issues, I call TCM and spoke to the Tech Rep. He is the same person who spoke at Oshkosh. The issue with the impuse mag only affects the ones installed on the fifth counter weight crankshafts on specific Lycomings, like the D4A5 series. According to this rep, the fifth counter weight crank is causing some potential castitrophic failures with the Slick impulse mag. He made no hesitation telling me to pull the Slick impulse mag and go to something else. Joe (tech rep at TCM) said this is not a TCM issue, it is a Lycoming issue. He told me that they (TCM) are pushing the FAA and Lycoming to issue a 100 hour repetitive inspection AD on the impulse mags, and may go as far as requesting an AD requiring removal of Slick impulse mags from all fifth counter weight Lycomings. I was told, as of now, they have no upcoming fixes to resove the problem, other then an AD. Soooooo, bye bye Slick mags.
