We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This AD was prompted by a report indicating that a portion of the sealant above the engine pylon between the wing skin and the vapor barrier might have been omitted. This AD requires an inspection for missing sealant in the seam on the outside and inside of the engine struts, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

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 certain The Boeing Company 
Model 787-8 and 787-9 airplanes. The NPRM published in the Federal 
Register on September 15, 2016 (81 FR 63433). The NPRM was prompted by 
a report indicating that a portion of the sealant above the engine 
pylon between the wing skin and the vapor barrier might have been 
omitted. The NPRM proposed to require an inspection for missing sealant 
in the seam on the outside and inside of the engine struts, and 
corrective actions if necessary. We are issuing this AD to detect and 
correct missing sealant above the engine pylon between the wing skin 
and the vapor barrier, which can create an unintended leak path for 
fuel, potentially draining onto the aft fairing heat shield above the 
engine and onto hot engine parts or brakes, which could lead to a major 
ground fire.

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

    Boeing and United Airlines (UAL) expressed support for the NPRM.

Request To Refer to Revised Service Information

    UAL requested that we revise the proposed AD to refer to Issue 002 
of Boeing Alert Service Bulletin B787-81205-SB570029-00. UAL stated 
that it disagrees with the finish requirement being an RC task. UAL 
pointed out that there is already an airworthiness limitation (AWL)/
Critical Design Configuration Control Limitations (CDCCL) task, 51-AWL-
01, for a paint requirement on the wing, resulting in a redundant AD 
requirement. UAL explained that Boeing plans to revise the service 
information to remove the requirement for applying finish over the 
newly applied sealant as a required for compliance (RC) task.
    We do not agree with UAL's request to revise this AD. When we 
incorporate service information by reference, we refer to approved or 
published service information. At the time of this action, Issue 002 of 
Boeing Alert Service Bulletin B78781205-SB570029-00 is not approved or 
published. We do not consider that delaying this action until after the 
release of a service bulletin revision is warranted. Boeing Alert 
Service Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 
2016, provides instructions that adequately address the missing sealant 
above the engine pylon between the wing skin and the vapor barrier, and 
provides the necessary steps to restore the finish disturbed by the 
required work.
    In addition, although UAL stated that Boeing plans to eliminate the 
RC designation for the finish restoration steps, Boeing has not 
received agreement from the FAA that such a proposal would be approved. 
The proper restoration of the finish, and particularly the thickness of 
the entire set of finish layers, is safety critical for the reasons 
stated in the related AWL. We do not view the AD requirement for finish 
restoration to be redundant relative to the AWL. The AWL requires that, 
following maintenance, alteration, and repair activity, the finish must 
be restored to the specifications contained in the AWL. We, therefore, 
expect the data used for any maintenance, alteration, or repair 
activity that disturbs that finish (in this case Boeing Alert Service 
Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 2016) to 
contain instructions that result in restoration of the finish to the 
standard contained in the AWL. For

[[Page 24021]]

these reasons, we do not agree with elimination of the RC designation 
for the referenced steps.
    We also do not agree that an operator can develop their own 
alternative finish restoration procedures without FAA or Boeing 
Commercial Airplanes Organization Designation Authorization (ODA) 
engineering review and approval of an alternative method of compliance 
(AMOC) in accordance with the procedures specified in paragraph (h) of 
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 AD as proposed, except for 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.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB570029-00, 
Issue 001, dated February 23, 2016. The service information describes 
procedures for doing an inspection for missing sealant in the seam on 
the outside and inside of the engine struts, and installing missing 
sealant. 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 32 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
              Action                        Labor cost            Parts cost        product         operators

                                     hour = $255.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
will be required based on the results of the inspection. We have no way 
of determining the number of aircraft that might need these repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that will enable us to provide cost estimates for the on-condition
  material costs 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 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.

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.

Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 2016.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
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 ACO, send it to the 
attention of the person identified in paragraph (i) of this AD. 
Information may be emailed to: [email protected].
    (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, 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) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(h)(4)(i) and (h)(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 sub-step is labeled ``RC Exempt,'' then 
the RC requirement is removed from that step or sub-step. 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.
