## Discrepancy

WHILE PERFORMING A P2 INSPECTION, CORROSION WAS DISCOVERED ON THE FLOORBEAM END CAP IN TWO LOCATIONS AT FRAME 5295. THE CORROSION REMOVAL RESULTED IN A MAXIMUM MATERIAL LOSS IN THE PRIMARY STRUCTURE OF 0.035 INCHES IN DEPTH. TECHNICAL DATA PACKAGE PR2018023 WAS CREATED TO PROVIDE GUIDANCE FOR REPAIR OF THE PRIMARY STRUCTURE USING AQRD ERO-931486 AS APPROVED REPAIR DATA. ONCE THE REPAIR IS COMPLETED, SUPPLEMENTAL INFORMATION MAY BE ADDED TO THIS SDR.
SUPPLEMENTAL INFORMATION - FLOORBEAM REPAIR ACCOMPLISHED IAW AIRLIFT TDP PROJECT PR2018032 REV B,ERO-931486A,AND FAA 8110-3 NUMBER 931486A ON FILE WITH AIR CARRIER. THIS INFORMATION WILL COMPLETE THIS SDR.
