14 CFR Part 39

[Docket No. FAA-2017-1176; Product Identifier 2017-NM-123-AD; Amendment 
39-19237; AD 2018-07-06]
RIN 2120-AA64

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 747-8 series airplanes. This AD was prompted 
by a report of restricted movement of the right brake pedals after 
landing rollout. This AD requires revising the airplane flight manual 
(AFM) by adding an autobrake system limitation. This AD also requires 
modifying intercostal webs near a main entry door, which terminates the 
AFM limitation. We are issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective May 14, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 14, 
2018.

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 747-8 series airplanes. The NPRM published in the Federal 
Register on January 2, 2018 (83 FR 80). The NPRM was prompted by a 
report of restricted movement of the right brake pedals after landing 
rollout. The NPRM proposed to require revising the AFM by adding an 
autobrake system limitation. The NPRM also proposed to require 
modifying intercostal webs near a main entry door, which would 
terminate the AFM limitation revision. We are issuing this AD to 
prevent restricted motion of the brake pedals, which can affect 
stopping performance and directional control of the airplane. This 
restricted motion can lead to high speed runway excursion or lateral 
runway excursion.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comment received. Boeing stated 
its support for the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule 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 addressing 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 Requirements Bulletin 747-32A2525 RB, 
dated September 6, 2017. This service information describes procedures 
for modifying intercostal webs near main entry door 3 by drilling two 
drain holes in the station-18 intercostal web at door stop 8 and 
applying sealant at the fore-aft drain path of the upper main sill web 
at station 16 near door 3R and door 3L. 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 2 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that enables us to provide parts cost estimates for the modification
  specified in this AD.

[[Page 15042]]

    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.
    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.
