SUPPLEMENTARY INFORMATION:
Discussion
The FAA 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 787-8 airplanes. The NPRM published in the Federal
Register on November 19, 2019 (84 FR 63825). The NPRM was prompted by a
report of fatigue cracking at certain frame tie rod locations of the
wing. The NPRM proposed to require repetitive inspections for cracking
of the left- and right-side frame tie rod assemblies and stub beam
upper chords, and applicable on-condition actions.
The FAA is issuing this AD to address cracking in the frame tie rod
assemblies and consequent failure of a principal structural element to
sustain limit load, which could adversely affect the structural
integrity of the airplane and result in possible decompression of the
airplane.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comment
received. Boeing indicated its support for the NPRM.
Conclusion
The FAA 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. The FAA has determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin B787-81205-
SB570041-00 RB, Issue 001, dated March 7, 2019. The service information
describes procedures for repetitive high frequency eddy current (HFEC)
inspections for cracking of the left- and right-side frame tie rod
assemblies, repetitive ultrasonic (UT) inspections for cracking of the
left- and right-side stub beam upper chords, and applicable on-
condition actions. On-condition actions include repair. 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
The FAA estimates that this AD affects 55 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspections........... 19 work-hours x $85 per $0 $1,615 per inspection $88,825 per
hour = $1,615 per cycle. inspection cycle.
inspection cycle.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that enables the agency to
provide cost estimates for the on-condition actions specified in this
AD.
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.
The FAA is 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) Will not affect intrastate aviation in Alaska, and
(3) 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.
