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United Parcel Service (UPS) requested that the NPRM be withdrawn.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:
<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 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.

with the AD. If a step or substep is labeled ``RC Exempt,'' then the
RC requirement is removed from that step or substep. An AMOC is
required for any deviations to RC steps, including substeps and
identified figures.
(ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.
