## Discrepancy

ENGINE LOST POWER ON TAKE-OFF.  PILOT LANDED IN BOG AND FLIPPED OVER.  PRELIMINARY INSPECTION SHOWED DAMAGE TO INDUCTION IMPELLER.  TEARDOWN REVEALED IMPELLER SHAFT SUPPORTED BY TWO BRONZE BUSHINGS WHICH ARE LUBRICATED BY AN .1250 INCH HOLE ON BOTH BUSHINGS AND BY A .0625 INCH HOLE ON BOTH BUSHINGS AND BY A .0625 INCH HOLE ON ONE BUSHING.  THE .0625 INCH HOLE WAS BLOCKED, UNABLE TO DETERMINE IF BLOCKAGE WAS CAUSE OR CONSEQUENCE OF THE FAILURE, ATTRIBUTED TO LACK OF LUBRICATION.
