Slick/Unison has issued
SB3-08A to address issues with their carbon brushes on their magnetos listed
in their SB. Please read it or bring it to your mechanics attention if you have
Slick Mags.
Here is another Slick/Unison Service Bulletin
SB2-08A
Here is the FAA SAIB
CE-08-33
Beech Lister, CSOB Member and K35 Bo owner, Al
D., had Slick Mags affected by the SB and with only about 100
hrs TIS, here is what they found:
You can see the carbon buildup on the tab.
If you look closely at the picture of the
brush, you'll see the step-down.
So if you have Slick Mags affected by this SB,
get them checked out. The replacement brushes are only about $9.00 per Mag.
By the way, the Slick Master Service Manual
calls for their Mags to be removed, inspected and replace any components as
necessary at 500 hours. At 1000 hours remove, inspect and replace the sealed
bearings.
Thanks Al for this pirep and the hi-resolution
pics!
