We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD requires a one-time inspection of the engine pylon wiring bracket on the left wing for the presence of an existing corner relief fillet, and corrective action if necessary. This AD was prompted by a report indicating that the engine pylon wiring bracket on certain airplanes was missing a corner relief fillet, which could result in stress concentration and cracking in the engine pylon wiring bracket. We are issuing this AD to detect and correct cracking in the engine pylon wiring bracket. Such cracking could result in damage to adjacent power feeders, subsequent electrical arcing in a flammable leakage zone, and consequent uncontrollable fire.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD requires a one-time 
inspection of the engine pylon wiring bracket on the left wing for the 
presence of an existing corner relief fillet, and corrective action if 
necessary. This AD was prompted by a report indicating that the engine 
pylon wiring bracket on certain airplanes was missing a corner relief 
fillet, which could result in stress concentration and cracking in the 
engine pylon wiring bracket. We are issuing this AD to detect and 
correct cracking in the engine pylon wiring bracket. Such cracking 
could result in damage to adjacent power feeders, subsequent electrical 
arcing in a flammable leakage zone, and consequent uncontrollable fire.

SUPPLEMENTARY INFORMATION:

Discussion

    We received a report indicating that the engine pylon wiring 
bracket on certain airplanes is missing a corner relief fillet, because 
the engineering graphics for the engine pylon wiring bracket located on 
the left wing did not contain the corner relief fillet. A missing 
corner relief fillet could result in stress concentration and cracking 
in the bracket. The engineering graphics were subsequently revised to 
add the corner relief fillet, but the engine pylon wiring bracket part 
number was not changed. Therefore, brackets with and without an 
existing corner relief fillet have the same bracket part number. We are 
issuing this AD to prevent cracking in the engine pylon wiring bracket. 
Such cracking could result in damage to adjacent power feeders, 
subsequent electrical arcing in a flammable leakage zone, and 
consequent uncontrollable fire.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB570012-00, 
Issue 001, dated March 14, 2013. The service information describes 
procedures for a one-time inspection of the engine pylon wiring bracket 
on the left wing for the presence of existing corner relief fillets, 
re-identification of any bracket with an existing corner relief fillet, 
and replacement of any bracket without an existing corner relief 
fillet. 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 issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    Currently, there are no domestic operators of the affected 
airplanes on the U.S. Register. Therefore, we find that notice and 
opportunity for prior public comment are unnecessary and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and

[[Page 58822]]

was not preceded by notice and an opportunity for public comment. 
However, we invite you to send any written data, views, or arguments 
about this AD. Send your comments to an address listed under the 
ADDRESSES section. Include the docket number and Directorate Identifier 
2016-NM-046-AD at the beginning of your comments. We specifically 
invite comments on the overall regulatory, economic, environmental, and 
energy aspects of this AD. We will consider all comments received by 
the closing date and may amend this AD 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 AD.

Costs of Compliance

    Currently, there are no affected airplanes on the U.S. Register. 
However, if an affected airplane is imported and placed on the U.S. 
Register in the future, 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 re-
identification or replacement that will be required based on the 
results of the inspection. We have no way of determining the number of 
aircraft that might need re-identification or replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                   Action                                 Labor cost                Parts cost        product
----------------------------------------------------------------------------------------------------------------
Re-identification of bracket...............  2 work-hours x $85 per hour = $170.              $0            $170
Replacement of bracket.....................  8 work-hours x $85 per hour = $680.           1,173           1,853
----------------------------------------------------------------------------------------------------------------

    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.

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.
