Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration FAA, DOT.
ACTION: Proposed rule; withdrawal.
AGENCY:

The FAA is withdrawing a notice of proposed rulemaking NPRM
that proposed to adopt a new airworthiness directive AD. That NPRM would have applied to certain The Boeing Company Model 737700, 800, and 900ER series airplanes. The NPRM was prompted by a report of unshimmed gaps at a certain frame inner chord. The NPRM would have required a general visual inspection for repairs of a certain frame inner chord, a detailed inspection for unshimmed gaps of the frame inner chord, and applicable on-condition actions. Since issuance of the NPRM, the FAA
determined that the proposed AD is inadequate to address the unsafe condition. The FAA intends to propose new rulemaking to incorporate changes to the proposed requirements and add airplanes that are also subject to the unsafe condition. Accordingly, the NPRM is withdrawn.
DATES: The FAA is withdrawing the proposed rule published on February 4, 2020 85 FR 6107, as of June 24, 2021.

Background The FAA issued an NPRM that proposed to amend 14 CFR part 39 by adding an AD that would apply to certain Boeing Model 737700, 800, and 900ER series airplanes. The NPRM
was published in the Federal Register on February 4, 2020 85 FR 6107. The NPRM was prompted by a report of unshimmed gaps at a certain frame inner chord.
The NPRM proposed to require a general visual inspection for repairs of a certain frame inner chord, a detailed inspection for unshimmed gaps of the frame inner chord, and applicable oncondition actions. The proposed actions were intended to address gaps at a frame inner chord, which may initiate early cracking in fatigue critical baseline structure FCBS and result in the inability of a principal structural element PSE to sustain limit load and adversely affect the structural integrity of the airplane.
Actions Since the NPRM Was Issued Since issuance of the NPRM, the FAA
determined that the proposed actions are inadequate to address the unsafe condition. In addition to identifying missing shims, Boeing has found a wrong type of shims, shanked fasteners, fastener head gaps, and incorrect fastener hole sizes. The unsafe condition and location of the problem are the same as those described in the NPRM. The FAA has identified additional Model 737700, 800, and 900ER airplanes as well as additional airplane models that are subject to the unsafe condition. The FAA has also determined that additional actions must be accomplished to address the unsafe condition on the affected airplanes. In light of these changes, the FAA intends to propose further rulemaking.
Withdrawal of the NPRM constitutes only such action. The withdrawal does not preclude the FAA from further rulemaking on this issue or commit the FAA to any course of action in the future.
Comments The FAA received comments on the NPRM from four commenters, including Aviation Partners Boeing, Boeing, Delta Air Lines, and United Airlines.
Although the FAA is withdrawing the NPRM because of new findings and not as a result of any of these comments, the following presents a brief discussion of the comments.
United Airlines concurred with the NPRM.
Aviation Partners Boeing and Delta Air Lines stated that the incorporation
