PN D5518000200000 WHICH WAS REMOVED FROM A/C 5053 IS CURRENTLY OUT OF PRODUCTION, SO PN D5518000800052 HTP ASSY-EQUIPPED WAS OFFERED TO DAL ALONG WITH THE APPROVAL TO INSTALL. CORRECTIVE ACTION: ER/A 632759-14 AUTHORIZES THE INSTALLATION OF THE AVAILABLE SPARE PN D5518000800052 (STOCK # 50-5510-9-0001, S/N CG20181, FTN 9GD3S8), WHICH INCLUDES ELEVATORS PN DW050A1AAAAJ (STOCK # 50-5520-9-0003, S/N CC20179, FTN 7XR2G2) AND PN DW050A1AAAAG (STOCK # 50-5520-9-0004, S/N CC20180, FTN 9R7MRM), ON A/C 5053 (MSN 12122) AS AN ALTERATION WITH AIRBUS APPROVAL.
