We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 turbofan engines. This AD was prompted by several instances of fuel leaks on PW engines installed with the Talon IIB combustion chamber configuration. This AD requires 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.

Airworthiness Directives; Pratt & Whitney Division Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Pratt & Whitney (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, 
PW4168A-1D, and PW4170 turbofan engines. This AD was prompted by 
several instances of fuel leaks on PW engines installed with the Talon 
IIB combustion chamber configuration. This AD requires 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.

DATES: This AD is effective December 6, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 6, 
2016.

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 
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:

[[Page 75687]]

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.

October 5, 2011, or original issue, and have fuel nozzles, part 
number (P/N) 51J345, installed;
    (2) PW4168A model engines with Talon IIA outer combustion 
chamber assembly, P/N 51J100, and fuel nozzles, P/N 51J345, with 
serial numbers CGGUA19703 through CGGUA19718 inclusive or CGGUA22996 
and higher, installed;
    (3) PW4168A-1D and PW4170 model engines with engine serial

September 30, 2011, or earlier revision, and have fuel nozzles, P/N 
51J345, installed.

(d) Unsafe Condition

    This AD was prompted by nine instances of fuel leaks on PW 
engines with the Talon IIB combustion chamber configuration 
installed. We are issuing this AD to prevent failure of the fuel 
nozzles, which could lead to engine fire and damage to the airplane.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Within 800 flight hours after the effective date of this AD, 
and thereafter within every 800 flight hours accumulated on the fuel 
nozzles, do the following:
    (i) Inspect all fuel nozzles, P/N 51J345. Use Part A of PW Alert 
Service Bulletin (ASB) PW4G-100-A73-45, dated February 16, 2016, to 
do the inspection.
    (ii) For any fuel nozzle that fails the inspection, before 
further flight, remove and replace it with a part that is eligible 
for installation.
    (2) At the next shop visit after the effective date of this AD, 
and thereafter at each engine shop visit, remove all fuel nozzles, 
P/N 51J345, unless fuel nozzles were replaced within the last 100 
flight hours. Use Part B of PW ASB PW4G-100-A73-45, dated February 
16, 2016, to replace the fuel nozzles with parts eligible for 
installation.

(f) Definitions

    (1) For the purpose of this AD, an ``engine shop visit'' means 
the induction of an engine into the shop for any maintenance.
    (2) For the purpose of this AD, a part that is ``eligible for 
installation'' is a fuel nozzle, with a P/N other than 51J345, that 
is FAA-approved for installation or a fuel nozzle, P/N 51J345, that 
meets the requirements of Part A, paragraph 4.B., or Part B, 
paragraph 1.B. of PW ASB PW4G-100-A73-45, dated February 16, 2016.

(g) Alternative Methods of Compliance (AMOCs)
