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 747-400, 747-400F, and 747-8F series airplanes. The NPRM published in the Federal Register on May 30, 2017 (82 FR 24595). The NPRM was prompted by reports of failure of the fastener assemblies on the crew access ladder handrails. The NPRM proposed to require replacing the fastener assemblies. We are issuing this AD to prevent the fastener assemblies from coming loose on the crew access ladder handrails, which could result in serious or fatal injury to personnel.
Comments
We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA's response to each comment.
Request To Withdraw the NPRM
United Parcel Service (UPS) requested that the NPRM be withdrawn. UPS pointed out that the crew access ladder is stowed during flight and stated that failure of the ladder does not affect safety of flight of the airplane. Therefore, UPS stated that the failure of the crew access ladder should not be the subject of an AD as it is outside the scope of 14 CFR part 39.
We do not agree with UPS's request. Title 14 part 39.5 states: ``FAA issues an airworthiness directive addressing a product when we find that: (a) An unsafe condition exists in the product; and (b) The condition is likely to exist or develop in other products of the same type design.'' This action does fall within the scope of 14 CFR part 39 because an unsafe condition exists in a product that is likely to exist in other products of the same design. In addition, the ladder is accessible to, and in some cases may be used by, the flight crew during flight. Incapacitation of a flight crew member during flight is considered a safety of flight issue. We have not changed this AD in this regard.
Requests To Revise Applicability To Match the Service Information
Boeing requested that we remove the ``Differences Between this Proposed AD and the Service Information'' section of the NPRM. Boeing explained that this information implies that airplanes delivered with compliant rotable hardware could have the rotable hardware subsequently replaced with non-compliant hardware. Boeing stated that this is very unlikely because compliant airplanes have the compliant rotable hardware sealed within a permanent protective cover.
UPS requested that we revise the applicability to remove Model 747-
8F series airplanes, line numbers (L/Ns) 1540 and on, specified in paragraphs (c)(2) and (c)(3) of the proposed AD. UPS asserted that Boeing has confirmed that those airplanes will have the compliant parts installed during production.
We partially agree with the commenters' requests. We do not agree to remove the ``Differences Between this Proposed AD and the Service Information'' section of the NPRM. This section is not restated in the final rule, so no change is necessary in this regard.
We agree that the likelihood of discrepant parts being installed on an airplane that is outside the applicability of Boeing Special Attention Service Bulletin 747-25-3693, dated November 10, 2016, is sufficiently low. Therefore, we have revised the applicability of this AD accordingly. We also removed paragraph (h) of the proposed AD from this AD and redesignated subsequent paragraphs accordingly.
Conclusion
We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
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 final rule.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Special Attention Service Bulletin 747-25-3693, dated November 10, 2016. The service information describes procedures for replacing the existing fastener assemblies with new assemblies on the crew access ladder handrails. 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 will affect 84 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
----------------------------------------------------------------------------------------------------------------
Replacement........................... 3 work-hours x $85 per $2,418 $2,673 $224,532
hour = $255.
----------------------------------------------------------------------------------------------------------------
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.
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 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.
