## Discrepancy

RIGHT MAGNETO FAILED AFTER CLIMBING TO ALTITUDE.  FOUND RT MAGNETO DISTRIBUTOR GEAR HAD FAILED.  METAL PLATE THAT ATTACHES TO THE MIDDLE OF THE GEAR AND EXTENDS TO THE EDGE HAD COME OFF.  THIS PIECE WAS LOCATED INSIDE THE MAGNETO.  UPON FURTHER INSP, THE MAGNETO APPEARS TO WORK NORMALLY.  BUT WITHOUT THIS PIECE IT IS UNABLE TO DISTRIBUTE THE ELECTRICAL CURRENT TO THE CONTACTS WHICH FEED THE PLUG WIRES.
