Discussion 

The FAA issued an NPRM to amend 

14 CFR part 39 by adding an AD that 

would apply to all The Boeing Company 

Model 737–100, –200, –200C, –300, 

–400, and –500 series airplanes. The 

NPRM published in the Federal 

Register on July 28, 2020 (85 FR 45355). 

The NPRM was prompted by crack 

indications found in the lower aft wing 

skin bolt holes where the flap tracks 

attach to the track support fitting. The 

NPRM proposed to require repetitive 

inspections for cracking of the left and 

right wing, lower aft wing skin aft edge, 

at certain flap track locations, and 

applicable on-condition actions. 

Actions Since the NPRM Was Issued 

Since the FAA issued the NPRM, the 

FAA determined that the compliance 

time should be reduced for airplanes on 

which Aviation Partners Boeing (APB) 

blended winglets have been installed 

using supplemental type certificate 

(STC) ST01219SE. 

Comments 

The FAA gave the public the 

opportunity to comment on the NPRM. 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Support for the NPRM 

One commenter, Jesse Smith, agreed 

with the intent of the NPRM. 

Request To Reduce Compliance Time 

for Certain Airplanes 

APB asked that the FAA revise this 

AD to reduce the compliance times 

required for accomplishing the specified 

actions for airplanes that have 

incorporated STC ST01219SE. APB 

stated that it issued APB Alert Service 

Bulletin AP737C–57–003, dated July 28, 

2020, (which contains the same actions 

as those specified in Boeing Alert 

Requirements Bulletin 737–57A1349 

RB, dated April 14, 2020, which is the 

source of service information for the 

actions specified in this proposed AD), 

with reduced compliance times for 

those airplanes, and, if approved by the 

FAA, could be added to paragraphs (g) 

and (h) of the proposed AD. 

The FAA agrees with the commenter’s 

request, and has reviewed Aviation 

Partners Boeing Alert Service Bulletin 

AP737C–57–003, dated July 28, 2020. 

The FAA revised paragraph (g) of this 

proposed AD, including adding 

paragraphs (g)(1) and (2) of this 

proposed AD. Paragraph (g)(2) of this 

proposed AD specifies, for airplanes on 

which winglets are installed using STC 

ST01219SE, doing the required actions 

in Boeing Alert Requirements Bulletin 

737–57A1349 RB, dated April 14, 2020, 

at the compliance times in Aviation 

Partners Boeing Alert Service Bulletin 

AP737C–57–003, dated July 28, 2020. 

The FAA has also added paragraphs 

(h)(4) and (5) of this proposed AD to 

provide exceptions to Aviation Partners 

Boeing Alert Service Bulletin AP737C– 

57–003, dated July 28, 2020. 

Request To Clarify Discussion Section 

Boeing asked that the Discussion 

section of the NPRM be clarified by 

removing ‘‘This condition, if not 

addressed’’ from the description of the 

unsafe condition, and instead starting 

the sentence with ‘‘undetected cracking 

in the lower wing skin could 

result. . . .’’ Boeing stated that the term 

‘‘this condition,’’ is not clearly defined 

and may lead to confusion. Boeing 

added that Boeing Alert Requirements 

Bulletin 737–57A1349 RB, dated April 

14, 2020, describes inspections for 

cracking, and removing that language 

will more specifically indicate the 

unsafe condition being addressed in the 


jbell on DSKJLSW7X2PROD with PROPOSALS
6278 Federal Register / Vol. 86, No. 12 / Thursday, January 21, 2021 / Proposed Rules 

referenced service information. Boeing 

noted that the suggested language is also 

consistent with the language for the 

unsafe condition specified in paragraph 

(e) of the proposed AD. 

The FAA acknowledges the 

commenter’s request. However, the 

sentence in question is not carried over 

to this SNPRM. The FAA has not 

changed this AD regarding this issue. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 737–57A1349 

RB, dated April 14, 2020, and Aviation 

Partners Boeing Alert Service Bulletin 

AP737C–57–003, dated July 28, 2020. 

The service information describes 

procedures for repetitive high frequency 

eddy current (HFEC) inspections for 

cracking of the left and right wing, 

lower aft wing skin aft edge, at flap track 

numbers 1, 2, 3, 6, 7, and 8 attachment 

location and applicable on-condition 

actions. On-condition actions include 

repairing any cracking found. These 

documents are distinct since they apply 

to different airplane models in different 

configurations. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

FAA’s Determination 

The FAA is proposing this AD 

because the agency evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. Certain changes described above 

expand the scope of the NPRM. As a 

result, the FAA has determined that it 

is necessary to reopen the comment 

period to provide additional 

opportunity for the public to comment 

on this SNPRM. 

Proposed Requirements of This SNPRM 

This SNPRM would require 

accomplishing the actions specified in 

the service information described 

previously. For information on the 

procedures and compliance times, see 

Boeing Alert Requirements Bulletin 

737–57A1349 RB, dated April 14, 2020, 

and Aviation Partners Boeing Alert 

Service Bulletin AP737C–57–003, dated 

July 28, 2020, at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2020– 

0587. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 141 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

HFEC inspections ............ 7 work-hours × $85 per hour = $595 per inspection cycle.$0 $595 per inspection 

cycle.

$83,895 per inspection 

cycle. 

The FAA has received no definitive 

data that would enable the FAA to 

provide cost estimates for the oncondition actions specified in this 

proposed AD. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs’’ describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

The Boeing Company: Docket No. FAA– 

2020–0587; Product Identifier 2020– 

NM–086–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 8, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 737–100, –200, 200C, –300, 

–400, and –500 series airplanes, certificated 

in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 57, Wings. 

(e) Unsafe Condition 

This AD was prompted by crack 

indications found in the lower aft wing skin 

bolt holes where the flap tracks attach to the 

track support fitting. The FAA is issuing this 

AD to address undetected cracking in the 

lower wing skin, which could result in the 

inability of the structure to carry limit load, 

and adversely affect the structural integrity of 

the airplane.
