Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–03– 

26, which applied to certain The Boeing 

Company Model 737–600, –700, –700C, 

–800, –900, and –900ER series 

airplanes. AD 2019–03–26 required 

modifying the passenger service units 

(PSUs) and life vest panels by replacing 

the existing inboard lanyard and 

installing two new lanyards on the 

outboard edge of the PSUs and life vest 

panels; measuring the distance between 

the hooks of the torsion spring of the 

lanyard assembly; replacing discrepant 

lanyard assemblies; and re-identifying 

serviceable lanyard assemblies. This AD 

was prompted by a determination that 

certain airplanes are listed in the wrong 

configuration and certain PSUs have not 

been correctly re-identified. This AD 

retains the requirements of AD 2019– 

03–26, and, for certain airplanes, 

requires an inspection to determine if 

the re-identified PSU part number is 

correct, and further re-identification if 

necessary. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD is effective February 15, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 15, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2019–03–26, 

Amendment 39–19578 (84 FR 7266, 

March 4, 2019) (AD 2019–03–26). AD 

2019–03–26 applied to certain The 

Boeing Company Model 737–600, –700, 

–700C, –800, –900, and –900ER series 

airplanes. The NPRM published in the 

Federal Register on June 30, 2021 (86 

FR 34653). The NPRM was prompted by 

a determination that certain airplanes 

are listed in the wrong configuration 

and certain PSUs have not been 

correctly re-identified. In the NPRM, the 

FAA proposed to continue to require the 

requirements of AD 2019–03–26, and, 

for certain airplanes, would require an 

inspection to determine if the reidentified PSU part number is correct, 

and further re-identification if 

necessary. The FAA is issuing this AD 

to address PSUs and life vest panels 

detaching from the supporting airplane 

structure, which could lead to passenger 

injuries and impede passenger and crew 

egress during evacuation. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two commenters, including The Boeing 

Company and an individual, who 

supported the NPRM without change. 

The FAA received additional 

comments from two other commenters, 

including All Nippon Airways (ANA) 

and Aviation Partners Boeing (APB). 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request To Allow Credit for Earlier 

Revision of Service Information 

ANA requested that the proposed AD 

be revised to add a note to allow use of 

Boeing Service Bulletin 737–25–1707, 

Revision 1, dated May 18, 2018. ANA 

stated that it has some airplanes that are 

identified as ‘‘Group 1’’ airplanes in 

Boeing Special Attention Service 

Bulletin 737–25–1707, Revision 2, dated 

July 27, 2020, and on which Revision 1 

of the service bulletin was 

accomplished. ANA added that the 

changes described in Revision 2 of the 

service bulletin do not affect the work 

instructions for airplanes identified as 

‘‘Group 1’’ and believed that Revision 1 

could also be used to comply with the 

proposed requirements. 

The FAA disagrees with the request to 

revise this AD to allow use of Boeing 

Service Bulletin 737–25–1707, Revision 

1, dated May 18, 2018, as it is not 

necessary. Group 1 is divided into three 

configurations, depending on whether 

or not earlier revisions of Boeing Special 

Attention Service Bulletin 737–25– 

1707, Revision 2, dated July 27, 2020, 

have been done. Group 1 airplanes on 

which Boeing Service Bulletin 737–25– 

1707, Revision 1, dated May 18, 2018, 

has been done are defined as Group 1, 

Configuration 3 airplanes. The 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 87, No. 7 / Tuesday, January 11, 2022 / Rules and Regulations 1339 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 737– 

25–1707, Revision 2, dated July 27, 

2020, specify for Group 1, Configuration 

3 airplanes, that no further action is 

required, and therefore this AD does not 

require further action. The FAA has not 

revised this AD in this regard. 

Effects of Winglets on Accomplishment 

of the Proposed Actions 

APB stated that the installation of 

winglets per Supplemental Type 

Certificate (STC) ST00830SE does not 

affect the accomplishment of the 

manufacturer’s service instructions. 

The FAA agrees with the commenter 

that STC ST00830SE does not affect the 

accomplishment of the manufacturer’s 

service instructions. Therefore, the 

installation of STC ST00830SE does not 

affect the ability to accomplish the 

actions required by this AD. The FAA 

has not changed this AD in this regard. 

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, 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 Special 

Attention Service Bulletin 737–25– 

1707, Revision 2, dated July 27, 2020. 

This service information specifies 

procedures for modifying the PSUs and 

life vest panels by: Replacing the 

existing inboard lanyard and installing 

two new lanyards on the outboard edge 

of the PSUs and life vest panels 

(secondary retention features); 

measuring the distance between the 

hooks of the torsion spring of the 

lanyard assembly; replacing any 

discrepant lanyard assemblies; and reidentifying serviceable lanyard 

assemblies. For some airplanes, the 

service information specifies procedures 

for inspecting PSUs for correct reidentification part numbers and, if 

necessary, re-identifying the PSU. 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 will 

affect 2,045 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 

Measurement and modification (retained 

actions from AD 2019–03–26).

Up to 70 work-hour × $85 

per hour = $5,950.

Up to $13,000 ........... Up to $18,950 ........... Up to $38,752,750. 

Inspection of re-identified parts (per 

PSU) (new actions).

1 work-hour × $85 per 

hour = $85.

$0 .............................. $85 ............................ $173,825. 

The FAA estimates the following 

costs to do any necessary replacements 

or re-identifications that will be 

required based on the results of the 

inspection. The FAA has no way of 

determining the number of aircraft that 

might need these replacements or reidentifications: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Replacement or re-identification (per PSU or life vest 

panel).

Up to 2 work-hour × $85 per hour = 

$170.

Up to $196 ................ Up to $366. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this AD may be covered under 

warranty, thereby reducing the cost 

impact on affected operators. 

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.
