## Discrepancy

(CAN) SMALL PIECE OF RUBBER FOUND FLOATING IN AIR SIDE OF NR 2 CYLINDER INJECTOR. THE PIECE APPEARED TO BE VERY DRY AND HARD O-RING MATERIAL, MOST LIKELY FROM THE BANJO FITTING SEALS.  NO OTHER FAULTS FOUND ON OTHER BANJO FITTINGS.  REMOVAL OF CONTAMINATION AND NEW SPARK PLUGS FOR THIS CYLINDER RETURNED THE AIRCRAFT TO NORMAL OPERATION.
