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.

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.

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

[[Page 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
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Installation of vapor seals, 136 work-hours x $85 per $21,910 $33,470 $435,110
heatshield seals, heatshield seal hour = $11,560.
retainers, block seals, and outboard
lateral restraint access panels.
----------------------------------------------------------------------------------------------------------------

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.

first, replace the part with a part 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,''

[[Page 38098]]

this AD requires using ``the effective date of this AD.''

(i) Terminating Action for Repetitive Inspections

Accomplishing the actions specified in paragraphs (g)(1) or
(g)(2) of this AD, as applicable, terminates all requirements of AD
2017-04-13.

(j) Parts Installation Prohibition

As of the effective date of this AD, do not install an access
panel lateral restraint with part numbers (P/Ns) 321U8595-1,

(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.
