Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–300, 

–400, and –500 series airplanes. This 

proposed AD was prompted by a report 

indicating that the primary latch 

securing the passenger service unit 

(PSU) to the airplane structure is not 

adequate for the higher loads 

experienced during survivable 

accidents. This proposed AD would 

require installing lanyard assemblies on 

the PSU and, for certain airplanes, on 

the life vest panel. We are proposing 

this AD to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by August 20, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2018–0580; Product Identifier 2018– 

NM–025–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this NPRM. We will consider 

all comments received by the closing 

date and may amend this NPRM 

because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received a report indicating 

that the primary latch securing the PSU 

to the airplane structure is not adequate 

for the higher loads experienced during 

survivable accidents. In addition, there 

is no secondary means of retention 

(lanyards) for the PSU to the airplane 

structure. This condition, if not 

corrected, could result in the PSU 

becoming detached and falling into the 

cabin, which could lead to passenger 

injuries and impede egress during an 

evacuation. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Service Bulletin 

737–25–1728, dated October 10, 2016. 

The service information describes 

procedures for installing lanyard 

assemblies on the PSU and life vest 

panels. 

We reviewed Boeing Requirements 

Bulletin 737–25–1758 RB, dated 

November 8, 2017. The service 

information describes procedures for 

installing lanyard assemblies on the 

PSU. 

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 

We are proposing this AD because we 

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. 

Proposed AD Requirements 

This proposed AD would require 

accomplishment of the actions 

identified as ‘‘RC’’ (required for 

compliance) in the Accomplishment 

Instructions of Boeing Service Bulletin 

737–25–1728, dated October 10, 2016, 

described previously, except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

This proposed AD would also require 

accomplishment of the actions 

identified in the Boeing Requirements 

Bulletin 737–25–1758 RB, dated 

November 8, 2017, described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD.

and locating Docket No. FAA–2018– 

0580. 

Explanation of Requirements Bulletin 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directives Implementation Aviation 

Rulemaking Committee (AD ARC), to 

enhance the AD system. One 

enhancement is a process for annotating 

which steps in the service information 

are ‘‘required for compliance’’ (RC) with 

an AD. Boeing has implemented this RC 

concept into Boeing service bulletins. 

In an effort to further improve the 

quality of ADs and AD-related Boeing 

service information, a joint process 

improvement initiative was worked 

between the FAA and Boeing. The 

initiative resulted in the development of 

a new process in which the service 

information more clearly identifies the 

actions needed to address the unsafe 

condition in the ‘‘Accomplishment 

Instructions.’’ The new process results 

in a Boeing Requirements Bulletin, 

which contains only the actions needed 

to address the unsafe condition (i.e., 

only the RC actions). 

Costs of Compliance 

We estimate that this proposed AD 

affects 227 airplanes of U.S. registry. We 

estimate 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 

Installation of lanyard assemblies .... 76 work-hour × $85 per hour = 

$6,460.

Up to $11,000 ..... Up to $17,460 ..... Up to $3,963,420. 

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. 

We are 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. 

This proposed AD is issued in 

accordance with authority delegated by 

the Executive Director, Aircraft 

Certification Service, as authorized by 

FAA Order 8000.51C. In accordance 

with that order, issuance of ADs is 

normally a function of the Compliance 

and Airworthiness Division, but during 

this transition period, the Executive 

Director has delegated the authority to 

issue ADs applicable to transport 

category airplanes to the Director of the 

System Oversight Division. 

Regulatory Findings 

We 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) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.
