Airworthiness Directive · Amendment 39-22794 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2025-15-09. Comply with the one in force.
This AD applies to all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2019-16- 05, which applied to all The Boeing Company Model 777 airplanes. AD 2019-16-05 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. This AD was prompted by reports of uncommanded fore/aft movement of the Captain's and First Officer's seats. This AD retains the requirements of AD 2019- 16-05 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 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.
Except as specified in paragraphs (i) and (j) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-25-0619, 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 Service Bulletin 777-25-0619, Revision 1, dated August 8, 2018, or Revision 2, dated January 27, 2023. As of the effective date of this AD, only Boeing Special Attention Service Bulletin 777-25-0619, Revision 2, dated January 27, 2023, may be used. Actions identified as terminating action in Boeing Special Attention Service Bulletin 777-25-0619, Revision 1, dated August 8, 2018, or 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 777-25-0619, Revision 1, dated August 8, 2018, or Revision 2, dated January 27, 2023.
(1) Where Boeing Special Attention Service Bulletin 777-25-0619, Revision 2, dated January 27, 2023, uses the phrase “the Original issue date of this service bulletin,” this AD requires replacing those words with “October 8, 2019 (the effective date of AD 2019-16-05).”
(2) Where Boeing Special Attention Service Bulletin 777-25-0607, Revision 2, dated January 27, 2023, specifies compliance for certain actions “within 72 months after the Original Issue date of this service bulletin,” this AD requires replacing those words with “within 36 months after October 8, 2019 (the effective date of AD 2019-16-05).”
(3) Where Boeing Special Attention Service Bulletin 777-25-0607, Revision 2, dated January 27, 2023, specifies compliance for certain actions “within 36 months after the Revision 2 date of this service bulletin,” this AD requires compliance within 36 months after the effective date of this AD.
If the airplane records show that an Ipeco Captain's or First Officer's seat meets any condition in figure 1 to paragraph (j) of this AD, the actions specified in this AD are not required for that seat.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
