Airworthiness Directive · Amendment 39-22930 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2025-15-08. Comply with the one in force.
(1) This AD applies to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC) ST01920SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE is installed, a “change in product” alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17.
The FAA is superseding Airworthiness Directive (AD) 2019-14- 13, which applies to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. AD 2019-14-13 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and performing applicable on-condition actions for affected seats. AD 2019-14-13 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats, and applicable on- condition actions. AD 2019-14-13 also provided an optional terminating action for the repetitive actions for certain seats. This AD was prompted by reports of uncommanded fore and aft movement of the Captain's and First Officer's seats. This AD retains the actions in AD 2019-14-13 and adds an inspection of previously omitted part numbers. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (i) and (j) of this AD: At the applicable time specified in the “Compliance,” paragraph of Boeing Special Attention Service Bulletin 767-25-0539, 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 all applicable on-condition actions, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0539, 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.
Except as specified by paragraphs (i) and (j) of this AD: At the applicable times specified in the “Compliance,” paragraph of Boeing Special Attention Bulletin 767-25-0549, Revision 2, dated January 27, 2023, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Special Attention Bulletin 767-25-0549, Revision 2, dated January 27, 2023. Actions identified as terminating action in Boeing Special Attention Bulletin 767-25-0549, Revision 2, dated January 27, 2023, terminate the applicable required actions of this AD, provided the terminating action is done in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0549, Revision 2, dated January 27, 2023.
(1) Where the “Compliance” paragraph of Boeing Special Attention Bulletin 767-25-0549, Revision 2, dated January 27, 2023, refers to the original issue date of the service bulletin, this AD requires using September 12, 2019 (the effective date of AD 2019-14-13).

(3) Where the “Compliance” paragraph of Boeing Special Attention Service Bulletin 767-25-0539, Revision 2, dated January 27, 2023, refers to within 72 months after the original issue date of the service bulletin, this AD requires using within 36 months after September 12, 2019 (the effective date of AD 2019-14-13).
(4) Where the “Compliance” paragraph of Boeing Special Attention Bulletin 767-25-0539, Revision 2, dated January 27, 2023, refers to the Revision 2 date of the service bulletin, this AD requires using the effective date of this AD.
If the airplane records show that an Ipeco Captain's or First Officer's seat meets all criteria specified in any row in figure 1 to paragraph (j) of this AD, the actions specified in paragraphs (g) and (h) of this AD are not required for that seat.
