Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 767-200 and -300 series airplanes. This AD was 
prompted by a report of a fire in the bilge area of the cargo 
compartment that burned through the insulation blankets that were 
intended to prevent smoke from migrating behind the cargo compartment 
sidewall liners and upward into the main cabin. This AD requires 
replacing the cargo compartment insulation blankets on the left and 
right sides with new insulation blankets that incorporate fire stops. 
We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective January 31, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 31, 
2017.

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 767-200 and -300 series airplanes. The NPRM published in the 
Federal Register on August 30, 2016 (81 FR 59549) (``the NPRM''). The 
NPRM was prompted by a report of a fire in the bilge area of the cargo 
compartment that burned through the insulation blankets that were 
intended to prevent smoke from migrating behind the cargo compartment 
sidewall liners and upward into the main cabin. The NPRM proposed to 
require replacing the cargo compartment insulation blankets on the left 
and right sides with new insulation blankets that incorporate fire 
stops. We are issuing this AD to prevent a fire in the bilge area of 
the cargo compartment burning through the insulation blankets and 
consequently allowing smoke to migrate behind the cargo compartment 
sidewall liners and upward into the main cabin.

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 expressed support for the NPRM.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST01920SE does not affect the 
accomplishment of the manufacturer's service instructions.
    We agree with the commenter that STC ST01920SE does not affect the 
accomplishment of the manufacturer's service instructions. Therefore, 
the installation of STC ST01920SE does not affect the ability to 
accomplish the actions required by 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR part 51

    We reviewed Boeing Special Attention Service Bulletin 767-25-0550, 
dated January 30, 2015. The service information describes procedures 
for replacing the cargo compartment insulation blankets on the left and 
right sides between stringers 29 and 33 with new insulation blankets 
that incorporate fire stops. 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 26 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
          Action              Labor cost       Parts cost        Cost per  product       Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Replacement..............  Up to 54 work-             (\1\)  Up to $4,590.............  Up to $119,340.
                            hours x $85 per
                            hour = $4,590.
----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that will enable us to provide parts cost estimates for the actions
  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.
