Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–300, –400, 

and –500 series airplanes. This AD was 

prompted by a manufacturer’s review 

that showed that the fuel tank access 

door at a certain wing buttock line did 

not have an engineered ground path 

with the mating wing structure. This AD 

requires replacing the fuel tank access 

door, doing a check of the electrical 

bond, doing related investigative and 

corrective actions if necessary, and 

revising the maintenance or inspection 

program by incorporating an 

airworthiness limitation (AWL). We are 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective September 

29, 2017. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 29, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all The Boeing Company Model 

737–300, –400, and –500 series 

airplanes. The NPRM published in the 

Federal Register on March 9, 2017 (82 

FR 13079). The NPRM was prompted by 

a report that the fuel tank access door 

at wing buttock line 191.00 did not have 

an engineered ground path with the 

mating wing structure. The NPRM 

proposed to require replacing the fuel 

tank access door, doing a check of the 

electrical bond, doing related 

investigative and corrective actions if 

necessary, and revising the maintenance 

or inspection program by incorporating 

an AWL. We are issuing this AD to 

prevent an ungrounded path that could 

result in an increased risk of ignition 

and subsequent fuel tank explosion in 

the event of a lightning strike. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Support for the NPRM 

The Air Line Pilots Association, 

International, stated that it supports the 

NPRM. 

Request To Revise the Proposed AD To 

State the Compliance Time and Remove 

an Exception 

Boeing requested that we revise 

paragraph (g) of the proposed AD to 

state the specific compliance time 

‘‘within 36 months after the effective 

date of this AD,’’ rather than referring to 

the service information for compliance 

times. Boeing suggested that providing 

the compliance time in the body of the 

proposed AD would minimize 

confusion and misunderstanding. 

Boeing also requested that we remove 

paragraph (i)(1) of the proposed AD, 

which specifies an exception to the 

compliance time stated in the service 

information. Boeing further noted that 

we would also need to renumber 

paragraph (i)(2) of the proposed AD and 

update references to the affected 

paragraphs of the proposed AD. Boeing 

pointed out that if we stated the specific 

compliance time as requested, the 

exception language in paragraph (i)(1) of 

the proposed AD is no longer necessary. 

We agree with the requested changes 

for the reasons provided by the 

commenter. We have revised this AD 

accordingly. 

Request To Correct the Certification 

Maintenance Requirements (CMR) 

Document Title 

Boeing requested that we correct the 

title of the CMR document from ‘‘Boeing 

737–12345 . . .’’ to ‘‘Boeing 737–100/ 

200/200C/300/400/500 . . . .’’ 

We agree with this request and have 

corrected the document title in this final 

rule.

40478 Federal Register / Vol. 82, No. 164 / Friday, August 25, 2017 / Rules and Regulations 

Effects 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. 

We agree with the commenter that 

STC ST01219SE does not affect the 

accomplishment of the manufacturer’s 

service instructions. Therefore the 

installation of STC ST01219SE does not 

affect the ability to accomplish the 

actions required by this AD. We have 

not changed this AD in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule with the changes described 

previously and minor editorial changes. 

We have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this final rule. 

Related Service Information Under 1 

CFR Part 51 

We reviewed the following service 

information. 

• Boeing Service Bulletin 737–57– 

1320, dated October 7, 2016, which 

describes procedures for replacing the 

fuel tank access door with a new 

installation that has two engineered 

ground paths between the new door 

assembly and the mating wing structure, 

doing a check of the electrical bond, and 

related investigative and corrective 

actions. 

• Boeing 737–100/200/200C/300/400/ 

500 Airworthiness Limitations (AWLs) 

and Certification Maintenance 

Requirements (CMRs) D6–38278–CMR, 

dated May 2016. The AWL required by 

this AD is AWL 28–AWL–30 ‘‘Upper 

Wing Fuel Tank Access Panel— 

Lightning Protection Electrical Design 

Features,’’ which describes features to 

verify during installation of the upper 

fuel tank access panel. 

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. 

Costs of Compliance 

We estimate that this AD affects 381 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Install new door assembly and check electrical bond.12 work-hours × $85 per hour = $1,020 ........ $2,237 $3,257 $1,240,917 

Revise maintenance or inspection program ... 1 work-hour × $85 per hour = $85 ................. 0 85 32,385 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this AD. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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 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 

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) Is not a ‘‘significant rule’’ under 

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.
