Airworthiness Directive · Amendment 39-19708 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2024-15-03. 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 adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by reports of uncommanded fore/aft movements of the Captain's and First Officer's seats. This AD requires an identification of the part number, and if applicable the serial number, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. The FAA is issuing this AD to address the unsafe condition on these products.
Within 36 months after the effective date of this AD, 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 1, dated July 17, 2018. 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 paragraph (i) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-25-0619, Revision 1, dated August 8, 2018 (“BSASB 777-25-0619, Revision 1”), do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of BSASB 777-25-0619, Revision 1.
For purposes of determining compliance with the requirements of this AD: Where BSASB 777-25-0619, Revision 1, uses the phrase “the original issue date of this service bulletin,” this AD requires using “the effective date of this AD.”
Installation of a serviceable Captain's or First Officer's seat as specified in, and in accordance with, the Accomplishment Instructions of BSASB 777-25-0619, Revision 1, terminates the repetitive checks required by paragraph (h) of this AD for that seat only.
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.
