This is VERY important! Now, this was quite a while ago but someone was caught with either VERY Light Pencil Marks or Pin Holes on the BLACK Tracing Paper. While this was pretty hard to see the CG Tester caught it when they held the blank sheet up to the light. The guy that got caught LOST all of his previous pilotage and was lucky to still have his license by the time the CG got through with him.
