What was found
WHILE CONDUCTING 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 WAS MEASURED AT 2.12 HIGH BY .77 WIDE, WITH A DEPTH OF .058. THE FUSELAGE FRAME AND STRIKER PLATE WILL BE REPLACED WITH FACTORY NEW PARTS.
