Required actions
Except as specified by paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Service Bulletin 747-53A2860, Revision 3, dated November 11, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Service Bulletin 747-53A2860, Revision 3, dated November 11, 2019.
Unsafe condition
This AD was prompted by reports of cracking in the outboard flange of the longeron extension fittings and the FAA's determination that additional airplanes are affected by the identified unsafe condition. The FAA is issuing this AD to address cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane.
Affected ADs
This AD replaces AD 2015-13-06, Amendment 39-18193 (80 FR 44835, July 28, 2015) (“AD 2015-13-06”).
