Models named: 787-8. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to The Boeing Company Model 787-8 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, dated March 7, 2019.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, dated March 7, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, dated March 7, 2019. Note 1 to paragraph (g) of this AD: Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin B787-81205-SB570041-00, Issue 001, dated March 7, 2019, which is referred to in Boeing Alert Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, dated March 7, 2019.

Unsafe condition

This AD was prompted by a report of fatigue cracking at certain frame tie rod locations of the wing. The FAA is issuing this AD to address cracking in the frame tie rod assemblies and consequent failure of a principal structural element to sustain limit load, which could adversely affect the structural integrity of the airplane and result in possible decompression of the airplane.

Affected ADs

None.
