Airworthiness Directive · Amendment 39-22110 · Flight controls
The Boeing Company Airplanes
This AD applies to The Boeing Company airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD.
(1) All Model 777-200, -200LR, -300, and -300ER series airplanes.
(2) Model 777F airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before the effective date of this AD.
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD superseded AD 2015-12-03, and applies to all The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes, and certain Model 777F airplanes. As published, a freeplay indicator value in the regulatory text is incorrect, and certain credit service information was omitted for certain actions in the regulatory text. This document corrects those errors. In all other respects, the original document remains the same.
This paragraph restates the requirements of paragraph (g) of AD 2015-12-03, with revised service information. For Model 777-200, -200LR, -300, and -300ER series airplanes: At the applicable times specified in tables 1, 2, and 3 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, or Revision 4, dated July 15, 2021, except as provided by paragraph (i)(1) of this AD: Inspect the freeplay of the right and left elevators, rudder, and rudder tab by accomplishing all of the actions specified in Parts 1, 3, and 5 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, or Revision 4, dated July 15, 2021, except as provided by paragraphs (i)(2) through (5) of this AD. Repeat the inspections thereafter at the intervals specified in tables 1, 2, and 3 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, or Revision 4, dated July 15, 2021. If, during any inspection required by this paragraph, the freeplay exceeds any applicable measurement specified in Part 1, 3, and 5, as applicable, of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, or Revision 4, dated July 15, 2021, before further flight, do the applicable corrective actions in accordance with Part 1, 3, and 5 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, or Revision 4, dated July 15, 2021.
