Slick/Unison has issued
SB3-08 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.
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!
TCM Offers a
Promotional Alternative to Slick Service Bulletins
They are offering what they call their ALPHA Mags which
consist of magnetos, harness and spark plugs. Once the mags reach the 500 hr
inspection point, the mags can be returned to TCM for replacement at $99.00 per
mag.
Since you will be replacing Slick during this first
installation, they will accept your Slick as cores and issue full core credit.
The amount of this credit will depend on the part that you order. Orders can be
placed through TCM Distributors or your FBO can contact them for ordering with
credit cards if you prefer. You will need to contact one of them in order
to get firm pricing on the ALPHA Mags that are right for your engine model and
spec.
