Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Proposed rule; withdrawal. 

SUMMARY: 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 737–700, 

–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NPRM is withdrawn.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.

SUPPLEMENTARY INFORMATION: 

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 737–700, –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 737–700, –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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Proposed Rules 33153 

of supplemental type certificate (STC) 

ST00830SE for installation of blended 

or split scimitar winglets does not affect 

compliance with the proposed actions, 

so a ‘‘change in product’’ alternative 

method of compliance (AMOC) would 

not be necessary. The FAA agrees with 

the commenters’ assertions, but because 

the FAA is withdrawing the NPRM, the 

request is no longer necessary. 

Delta Air Lines noted that the service 

information recommended removing 

sealant squeeze-out that inhibits 

inserting the feeler gauge between the 

mating surfaces. The commenter was 

concerned that removing the sealant 

squeeze-out could damage the structure 

if a metallic tool is used. The FAA 

disagrees with the request; however, 

because the NPRM is being withdrawn, 

the commenter’s requested change is 

unnecessary. 

Boeing requested several changes to 

the Discussion and Related Service 

Information Under 1 CFR part 51 

sections and the description of the 

unsafe condition in the NPRM. The 

FAA disagrees with Boeing’s requested 

changes. However, because the NPRM is 

being withdrawn, the commenter’s 

requested changes are unnecessary. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that the NPRM does not 

adequately address the identified unsafe 

condition. Accordingly, the FAA is 

withdrawing the NPRM. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule. This action therefore is not 

covered under Executive Order 12866, 

the Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

SUMMARY: The Coast Guard is reopening 

the comment period to solicit additional 

comments concerning its Notice of 

Proposed Rulemaking to change the 

drawbridge regulation governing the 

63rd Street Bridge, across Indian Creek, 

mile 4.0, at Miami Beach, Florida. The 

Coast Guard received a request from the 

City of Miami Beach, Florida to reopen 

the comment period. This request was 

made to allow the City of Miami Beach 

and members of the public to comment 

as they were unaware of the initial 

notice and comment period. 

DATES: Comments and related material 

must reach the Coast Guard on or before 

July 26, 2021. 

ADDRESSES: You may submit comments 

identified by docket number USCG– 

2020–0658 using Federal eRulemaking

SUPPLEMENTARY INFORMATION: 

I. Background and Purpose 

On April 12, 2021, we published a 

notice of proposed rulemaking (NPRM) 

entitled, ‘‘Drawbridge Operation 

Regulation; Indian Creek, Miami Beach, 

FL’’ in the Federal Register (86 FR 

18927). The original comment period 

closed on May 27, 2021. The NPRM 

proposed the initial change to the 

regulation governing the 63rd Street 

Bridge across Indian Creek, mile 4.0, at 

Miami Beach, Florida and contains 

useful background and analysis related 

to the initial proposed change. The 

public is encouraged to review the 

NPRM. 

The City of Miami Beach requested 

the Coast Guard consider reopening the 

comment period as the proposed 

regulation change impacts their 

residents and they misunderstood the 

regulatory process. Reopening the 

comment period will allow the City of 

Miami Beach to provide notification of 

the action to their residents. This action 

allows for a broader range of waterway 

and roadway users the comment on the 

proposed rule. 

This notice reopening the comment 

period ensures notice and opportunity 

to comment before making the proposed 

changes final. 

This notice is issued under authority 

of 33 U.S.C. 1223 and 5 U.S.C. 552. 

II. Public Participation and Request for 

Comments

essential to effective rulemaking, and 

will consider all comments and material 

received during the comment period.

docket number for this rulemaking, 

indicate the specific section of this 

document to which each comment
