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 737-57A1350 RB, dated April 23, 2020, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-57A1350 RB, dated April 23, 2020. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 737-57A1350, dated April 23, 2020, which is referred to in Boeing Alert Requirements Bulletin 737-57A1350 RB, dated April 23, 2020.
Unsafe condition
This AD was prompted by a report of missing sealant on the left and right wing leading edge outboard blowout door. The FAA is issuing this AD to address the missing sealant, which is intended to act as a fuel barrier. In the presence of a substantial fuel leak from the wing box, the unintended drain path could allow fuel to come into contact with the engine. This condition, if not addressed, could lead to a large ground fire.
Affected ADs
None.
