14 CFR Part 39

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:

Estimated Costs

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

Cost per Cost on U.S.

Action Labor cost Parts cost product operators

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

AFM revision...................... 1 work-hour x $85 per hour = $0 $85 $170

$85.

Modification...................... 10 work-hours x $85 per hour (\1\) 850 1,700

= $850.

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

\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.

(j) Ferry Flight Limitations

Operators who are prohibited from further flight due to the autobrake system being inoperative may perform a one-time non-

revenue ferry flight to fly the airplane to a maintenance facility to either fix the autobrake system or incorporate the terminating action specified in paragraph (h) of this AD. This ferry flight must be performed without passengers, and with interior modifications to allow heated cabin air to warm the brake control cables and pulleys in the vicinity of door 3L and door 3R. These interior modifications must include, at a minimum, temporarily removing the side panels and insulation immediately aft of door 3L and door 3R.
