ACTION: Final rule.

Background
The FAA is adopting a new airworthiness directive AD for all The Boeing Company Model 737100, 200, 200C, 300, 400, and 500 series airplanes. This AD was prompted by a report indicating that a crack was found on the splice angle flange that is attached to the station STA 540
bulkhead in the area between certain stringers. This AD requires repetitive surface high frequency eddy current HFEC inspections at the radius of the leftand right-side of the STA 540
bulkhead splice angle for any cracking, and applicable on-condition actions.
The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective July 29, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of July 29, 2021.
ADDRESSES: For service information identified in this final rule, contact
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to all The Boeing Company Model 737100, 200, 200C, 300, 400, and 500 series airplanes. The NPRM
published in the Federal Register on February 24, 2021 86 FR 11186. The NPRM was prompted by a report indicating that a crack was found on the splice angle flange that is attached to the STA 540 bulkhead in the area between certain stringers. In the NPRM, the FAA
proposed to require repetitive surface HFEC inspections at the radius of the leftand right-side of the STA 540
bulkhead splice angle for any cracking, and applicable on-condition actions.
The FAA is issuing this AD to address any cracking in the splice angle, which could result in the inability of a principal structural element to sustain limit load and could adversely affect the structural integrity of the airplane; in addition, such cracking could lead to
