This Slick service bulletin was released on Feb 6, 2019. I just discovered this bulletin buried deep within a Cessna multi-engine service bulletin. This impacts several 4 & 6 cylinder Slick mags manufactured from Jan 2016-May 2018.
Unfortunately my mags are effected. Google the SB number for more details.

OMG , I have just fitted some new mags [slick] due to the lack of parts and logistics and find another SB that the mags that has to be sent back to the USA. Maybe the surefly mags are not that bad . But I would have to change my prop to MT prop if I did .
