SUPPLEMENTARY INFORMATION:

Discussion

    We have received a report that members of the cabincrew on a Model 
787 airplane were injured when hot

[[Page 26565]]

water escaped during the opening of the steam oven door. The incident 
occurred with Jamco steam ovens, part number (P/N) ASN2001-1 and P/N 
ASN2001-12. Investigation revealed that the current water filter 
configuration allows foreign objects to enter the water system, which 
can prevent the solenoid valve from moving to a fully closed position 
and subsequently allow water to enter the steam oven cavity. Water in 
the steam oven cavity can become heated and then released when the door 
is opened. A new water filter assembly has been developed, which 
includes a larger screen to prevent foreign object debris from moving 
downstream to block the solenoid valve from moving to a fully closed 
position. This condition, if not addressed, could result in water 
becoming heated as it collects in the bottom of the oven during the 
cooking cycle, resulting in hot water escaping when the oven door is 
opened, and subsequent injury to the cabincrew.
    The Jamco steam ovens installed on Model 777-300ER series airplanes 
have the same part numbers as those installed on the affected Model 787 
airplane; therefore, Model 777-300ER series airplanes are subject to 
the same unsafe condition revealed on the Model 787 airplane. The 
unsafe condition on Model 787 airplanes has been addressed.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin 777-25-0617, dated June 6, 
2014. The service information describes procedures for replacing the 
water filter assembly in Jamco steam ovens, P/N ASN2001-1 and P/N 
ASN2001-12. 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

    There are currently no domestic operators of this product. 
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 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 final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2018-
0507 and Product Identifier 2018-NM-027-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this final rule. We will 
consider all comments received by the closing date and may amend this 
final rule 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 final rule.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, we provide the following cost estimates to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
             Action                      Labor cost          Parts cost               Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement.....................  1 work-hour x $85 per                $0  $85 per steam oven.
                                   hour = $85 per steam
                                   oven.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all 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 known 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 and 
associated appliances 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.
