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 757-27A0158 RB, dated July 9, 2020, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-27A0158, dated July 9, 2020, which is referred to in Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020.
Unsafe condition
This AD was prompted by reports of unwanted lateral oscillations during landing operations, and the development of wiring changes for certain spoiler control modules (SCMs), which will improve the lateral handling qualities of the airplane during approach and landing. The FAA is issuing this AD to address unwanted lateral oscillations during landing operations, which could cause over-control of the airplane and subsequent lateral pilot induced oscillation, which could affect continued safe flight and landing.
Affected ADs
This AD replaces AD 2017-26-10, Amendment 39-19141 (82 FR 61675, December 29, 2017).
