Required actions
Except as specified in paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 777-53A0081, Revision 2, dated March 29, 2019, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 777-53A0081, Revision 2, dated March 29, 2019. Replacing an underwing longeron, including doing all applicable on-condition actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 777-53A0081, Revision 2, dated March 29, 2019, except as required by paragraph (h)(2) of this AD, terminates the repetitive inspections specified in tables 1 through 6 and table 15 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 777-53A0081, Revision 2, dated March 29, 2019, for that longeron only.
Unsafe condition
This AD was prompted by reports of cracks on the underwing longerons. The FAA is issuing this AD to address cracks in the underwing longerons, which could result in fuel leakage into the forward cargo area and consequent increased risk of a fire or, in a more severe case, could adversely affect the structural integrity of the airplane.
Affected ADs
This AD replaces AD 2017-16-10, Amendment 39-18987 (82 FR 39513, August 21, 2017) (“AD 2017-16-10”).
