## Discrepancy

WHILE CONDUCTION OTHER MAINTENANCE, AN AREA OF CORROSION WAS NOTED ON THE FUSELAGE FRAME ASSEMBLY AT FS 214.00, JUST ABOVE THE 501110-12 STRIKER PLATE FOR THE LOWER PASSENGER DOOR PIN.  THE 501110-12 STRIKER PLATE WAS REMOVED FOR FURTHER INSPECTION.  UPON REMOVAL OF THE STRIKER PLATE, MORE CORROSION WAS DISCOVERED.  THIS AREA OF CORROSION MEASURED AT 2 HIGH BY .75 WIDE, WITH A DEPTH OF .055.  THE FUSELAGE FRAME AND STRIKER PLATE WERE REPLACED WITH NEW PARTS.
