## Discrepancy

100 RPM MAGNETO DROP ON PRE-FLIGHT RUN-UP.  INSPECTED ALL FOUR MAGNETOS ON BOTH ENGINES.
FOUND ALL MAGNETO CAMS WORN. NO LUBRICATION WAS FOUND ON THE CAMS. THESE MAGNETOS HAD 444.0 HRS TIME SINCE NEW, AND HAD COME INSTALLED ON NEW ENGINES. THEY HAD NOT HAD THEIR FIRST 500 HR INSPECTION, SO HAD NEVER BEEN INSPECTED/OPENED SINCE NEW.  SLICK 6310 MAGNETOS, SN'S: 06121306, 06121346, 06120367, AND 06121304.
