## Discrepancy

AIRCRAFT ARRIVED NEW  TO THE REPAIR STATION FOR FLOAT INSTALLATION MODIFICATION. UPON REMOVING PROPELLER FOR OUTSIDE  PITCH LOCK MODIFICATION, WE FOUND THE SPECIAL CHAMFERED HEAD BOLTS PN B-3339 AND SPECIAL CHAMFERED WASHERS PN A-2048-2 ATTACHING THE PROPELLER TO THE MOUNTING FLANGE WERE IMPROPERLY INSTALLED. THE SPECIAL WASHER WAS NOT PROPERLY ALIGNED WITH THE BOLT HEAD.
