replacement with parts eligible for
installation. We are issuing this AD to
prevent failure of the fuel nozzles,
which could lead to engine fire and
damage to the airplane.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the NPRM and the FAA’s
response to each comment.
Request To Change Definition of Engine
Shop Visit
Delta Air Lines (Delta) requested that
the definition of an ‘‘engine shop visit’’
be defined as the induction of an engine
into the shop for maintenance involving
the separation of pairs of major mating
engine flanges. Delta requested this
change so that the definition of an
engine shop visit in this AD would be
consistent with prior ADs.
We disagree. The redefined shop visit
interval as requested would result in
less frequent replacements of fuel
nozzles and an unacceptable fleet risk.
We did not change this AD.
Conclusion
We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting this AD
as proposed.
Related Service Information Under 1
CFR Part 51
We reviewed PW Alert Service
Bulletin (ASB) PW4G–100–A73–45,
dated February 16, 2016. The ASB
describes procedures for inspecting and
replacing the fuel nozzles. 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
72 engines installed on airplanes of U.S.
registry. We also estimate that it will
take about 2.2 hours per engine to
perform each inspection and 48 hours
per engine to replace the fuel nozzle.
The average labor rate is $85 per hour.
We also estimate that parts cost would
be $15,780 per engine. Based on these
figures, we estimate the cost of this AD
on U.S. operators to be $1,443,384.
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:
E:\FR\FM\01NOR1.SGM
01NOR1
Federal Register / Vol. 81, No. 211 / Tuesday, November 1, 2016 / Rules and Regulations
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.

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 PW PW4164, PW4164-
1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 turbofan
engines. The NPRM published in the Federal Register on April 20, 2016
(81 FR 23217) (``the NPRM''). The NPRM was prompted by several
instances of fuel leaks on PW engines installed with the Talon IIB
combustion chamber configuration. The NPRM proposed to require initial
and repetitive inspections of the affected fuel nozzles and their
replacement with parts eligible for installation. We are issuing this
AD to prevent failure of the fuel nozzles, which could lead to engine
fire and damage to the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and

an engine shop visit in this AD would be consistent with prior ADs.
We disagree. The redefined shop visit interval as requested would
result in less frequent replacements of fuel nozzles and an
unacceptable fleet risk. We did not change this AD.
