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 all The 

Boeing Company Model 747–8 and 747– 

8F series airplanes. This proposed AD 

was prompted by reports of damaged 

vapor seals, block seals, and heat shield 

seals on the outboard pylons between 

the engine strut and aft fairing. This 

proposed AD would require installing 

new aft fairing vapor seals, heatshield 

seals, heatshield seal retainers, block 

seals and outboard lateral restraint 

access panels. We are proposing this AD 

to address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by September 17, 

2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

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– 

2018–0703; Product Identifier 2018– 

NM–007–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 reports of damaged 

vapor seals, block seals, and heat shield 

seals on the outboard pylons between 

the engine strut and aft fairing. Such 

damage could allow flammable fluid 

leakage out of the aft fairing. This 

condition, if not addressed, could result 

in an uncontrolled fire in the engine 

strut. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin 747–54A2247, dated August 3, 

2017. This service information describes 

procedures for installing new aft fairing 

vapor seals, heatshield seals, heatshield 

seal retainers, block seals, and outboard 

lateral restraint access panels. 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 Alert Service 

Bulletin 747–54A2247, dated August 3, 

2017, described previously, except as 

discussed under ‘‘Differences Between 

this Proposed AD and the Service 

Information,’’ and except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

For information on the procedures 

and compliance times, see this service 

information at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0703. 

Differences Between This Proposed AD 

and the Service Information 

The applicability in this proposed AD 

does not refer to paragraph 1.A., 

‘‘Effectivity,’’ of Boeing Alert Service 

Bulletin 747–54A2247, dated August 3, 

2017. The service information does not 

contain a comprehensive list of the 

airplanes affected by the identified 

unsafe condition because the spare parts 

identified in paragraph (j) of this AD 

have been determined to be rotable parts 

that are capable of being installed on all 

Model 747–8 and 747–8F series 

airplanes. Therefore, the applicability of 


amozie on DSK3GDR082PROD with PROPOSALS1
Federal Register / Vol. 83, No. 150 / Friday, August 3, 2018 / Proposed Rules 38097 

this proposed AD is all Model 747–8 

and 747–8F series airplanes. We have 

coordinated this difference with Boeing. 

Costs of Compliance 

We estimate that this proposed AD 

affects 13 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 vapor seals, heatshield seals, heatshield seal 

retainers, block seals, and outboard lateral restraint access panels.

136 work-hours × $85 per 

hour = $11,560.

$21,910 $33,470 $435,110 

According to the manufacturer, some 

or all of the costs of this proposed 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 available 

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 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. 

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 (AD): 

The Boeing Company: Docket No. FAA– 

2018–0703; Product Identifier 2018– 

NM–007–AD. 

(a) Comments Due Date 

We must receive comments by September 

17, 2018. 

(b) Affected ADs 

This AD affects AD 2017–04–13, 

Amendment 39 18808 (82 FR 11795, 

February 27, 2017) (‘‘2017–04–13’’). 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 747–8 and 747–8F series 

airplanes, certificated in any category. 

(d) Subject

America Code 54, Nacelles/pylons. 

(e) Unsafe Condition 

This AD was prompted by reports of 

damaged vapor seals, block seals, and heat 

shield seals on the outboard pylons between 

the engine strut and aft fairing. We are 

issuing this AD to address heat damage to the 

vapor seals between the engine strut and aft 

fairing. Such damage could allow flammable 

fluid leakage out of the aft fairing, which 

could result in an uncontrolled fire in the 

engine strut.

number that is identified as an acceptable 

replacement in Boeing Alert Service Bulletin 

747–54A2247, dated August 3, 2017. 

(h) Exceptions to Service Information 

Specifications 

For purposes of determining compliance 

with the requirements of this AD: Where 

Boeing Alert Service Bulletin 747–54A2247, 

dated August 3, 2017, uses the phrase ‘‘the 

original issue date of this service bulletin,’’ 


amozie on DSK3GDR082PROD with PROPOSALS1
38098 Federal Register / Vol. 83, No. 150 / Friday, August 3, 2018 / Proposed Rules 

this AD requires using ‘‘the effective date of

(k) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or local Flight Standards 

District Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in paragraph (l)(1) of 

this AD. Information may be emailed to: 9- 

ANM-Seattle-ACO-AMOC-Requests@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair, 

modification, or alteration required by this 

AD if it is approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) that has 

been authorized by the Manager, Seattle ACO 

Branch, FAA, to make those findings. To be 

approved, the repair method, modification 

deviation, or alteration deviation must meet 

the certification basis of the airplane, and the 

approval must specifically refer to this AD. 

(4) Except as required by paragraph (h) of 

this AD: For service information that 

contains steps that are labeled as RC, the 

provisions of paragraphs (k)(4)(i) and 

(k)(4)(ii) of this AD apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.
