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 Honeywell TFE731-4, -4R, -
5AR, -5BR, and -5R turbofan engines with ITT duct, part number (P/N)
3075292-4, installed, with a serial number (S/N) listed in Table 2 of
Honeywell Service Bulletin (SB) TFE731-72-3789, Revision 0, dated March
23, 2015. The NPRM published in the Federal Register on October 29,
2015 (80 FR 66481). The NPRM was prompted by report of certain ITT
ducts that were not properly heat treated and failed to meet
containment capability requirements. The NPRM proposed to require
replacing certain ITT ducts. We are issuing this AD to correct the
unsafe condition on these products.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 66481, October 29,
2015) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (80 FR 66481, October 29, 2015) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 66481, October 29, 2015).
Related Service Information Under 1 CFR Part 51
We reviewed Honeywell SB TFE731-72-3789, Revision 0, dated March
23, 2015. The SB describes procedures for removing affected ITT ducts.
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 47 engines installed on airplanes
of U.S. registry. We also estimate that it will take about 2 hours per
engine to comply with this AD. The average labor rate is $85 per hour.
We estimate that replacement parts will cost $15,000 per engine. Based
on these figures, we estimate the total cost of the AD to U.S.
operators to be $712,990.
[[Page 18461]]
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.
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 to the extent
that it justifies making a regulatory distinction, 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.
