AD was prompted by an evaluation by 

the design approval holder (DAH) 

indicating that the frame splice between 

certain stringers is subject to 

widespread fatigue damage (WFD). This 

AD requires an inspection of certain 

fuselage frame splices for existing 

repairs, repetitive inspections of certain 

fuselage frame splices for 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 February 22, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 22, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 737–300, –400, and –500 series 

airplanes. The NPRM published in the 

Federal Register on August 24, 2021 (86 

FR 47255). The NPRM was prompted by 

an evaluation by the DAH indicating 

that the frame splice between certain 

stringers is subject to WFD. In the 

NPRM, the FAA proposed to require an 

inspection of certain fuselage frame 

splices for existing repairs, repetitive 

inspections of certain fuselage frame 

splices for cracking, and applicable oncondition actions. The FAA is issuing 

this AD to address upper frame cracking 

common to the frame splice between 

stringer S–13 and S–14, which could 

interact with stringer S–14 skin lap 

splice lower fastener row cracking in 

lower skin and result in an uncontrolled 

decompression of the airplane and loss 

of structural integrity.

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

Aviation Partners Boeing and Boeing. 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

the installation of winglets per 

Supplemental Type Certificate STC 

ST01219SE does not affect the 

accomplishment of the manufacturer’s 

service instructions. 

The FAA concurs with the 

commenter. The FAA has redesignated 

paragraph (c) of the proposed AD as 

paragraph (c)(1) of this AD and added 

paragraph (c)(2) to this AD to state that 

installation of STC ST01219SE does not 

affect the ability to accomplish the 

actions required by this AD. Therefore, 

for airplanes on which STC ST01219SE 

is installed, a ‘‘change in product’’ 

alternative method of compliance 

(AMOC) approval request is not 

necessary to comply with the 

requirements of 14 CFR 39.17. 

Request To Add Inspection Method 

Boeing requested that the words ‘‘high 

frequency eddy current (HFEC)’’ be 

added to the sentence that describes the 

repetitive inspections in the ‘‘Related 

Service Information under 1 CFR part 

51’’ section of the proposed AD. Boeing 

stated that the HFEC inspection should 

be mentioned because that is the 

inspection that mitigates the unsafe 

condition. 

The FAA agrees with the request. The 

requested wording has been added to 

the specified section of this final rule. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, and any 

other changes described previously, this 

AD is adopted as proposed in the 

NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 737–53A1388 

RB, dated October 27, 2020. This service 

information specifies procedures for a 

general visual inspection (GVI) of the 

fuselage frame splices between stringer 

S–13 and S–14 station (STA) 360 to STA 

520 and STA 727A to STA 907 for 

existing repairs, repetitive high 

frequency eddy current (HFEC) 

inspections of the fuselage frame splices 

between stringer S–13 and S–14 from 

STA 360 to STA 520 and STA 727A to 

STA 907 for cracking, and applicable 

on-condition actions. On-condition 

actions include an open hole HFEC 

inspection for cracking at all fastener 

hole locations where a fastener was 

removed due to finding a cracked 

doubler, repair, or replacement. 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 ADDRESSES. 

Costs of Compliance 

The FAA estimates that this AD 

affects 66 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts 

cost Cost per product Cost on U.S. operators 

Repetitive Inspections .... Up to 267 work-hours × $85 per hour = Up to 

$22,695 per inspection cycle.

$0 Up to $22,695 per inspection cycle.Up to $1,497,870 per inspection cycle. 

GVI ................................. 2 work-hours × $85 per hour = $170 ..................... 0 $170 ............................... $11,220. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions specified in 

this 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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(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.
