(g) Seat Part Number Identification and On-Condition Actions Except as specified in paragraphs (i) and (j) of this AD: At the applicable time specified in paragraph 1.E., "Compliance," of Boeing Special Attention Service Bulletin 777-25-0607, Revision 2, dated January 27, 2023, do an inspection to determine the part number, and serial number as applicable, of the Captain's and First Officer's seats, and do all applicable on-condition actions, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-25-0607, Revision 2, dated January 27, 2023. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and serial number of the Captain's and First Officer's seats can be conclusively determined from that review.
