We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW4164-1D, PW4168-1D, PW4168A-1D and PW4170 engines, and certain PW4164, PW4168, and PW4168A turbofan engines. This proposed AD was prompted by fuel nozzle-to-fuel supply manifold interface fuel leaks. This proposed AD would require inspecting fuel nozzles for signs of leakage, replacing hardware as required, and torqueing to specified requirement. We are proposing this AD to prevent fuel leaks which could result in engine fire and damage to the airplane.

Airworthiness Directives; Pratt & Whitney Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Pratt & Whitney (PW) PW4164-1D, PW4168-1D, PW4168A-1D and PW4170 
engines, and certain PW4164, PW4168, and PW4168A turbofan engines. This 
proposed AD was prompted by fuel nozzle-to-fuel supply manifold 
interface fuel leaks. This proposed AD would require inspecting fuel 
nozzles for signs of leakage, replacing hardware as required, and 
torqueing to specified requirement. We are proposing this AD to prevent 
fuel leaks which could result in engine fire and damage to the 
airplane.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this NPRM. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2014-1130; 
Directorate Identifier 2015-NE-04-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this NPRM. We will 
consider all comments received by the closing date and may amend this 
NPRM because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this NPRM.

Discussion

    We received reports of four fuel nozzle leaks in service and an 
additional six fuel nozzle leaks found during shop visits. The root 
cause is inadequate torque of the fuel nozzle-to-fuel supply manifold 
B-nuts for the temperatures that the fuel nozzles experience. This 
condition, if not corrected, could result in engine fire and damage to 
the airplane.

[[Page 22141]]

Related Service Information Under 1 CFR Part 51

    We reviewed PW Alert Service Bulletin (ASB) No. PW4G-100-A73-44, 
dated October 10, 2014. This service information contains information 
regarding fuel nozzle manifold inspection and fuel nozzle-to-fuel 
supply manifold B-nut torque requirements. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or see ADDRESSES for other ways 
to access this service information.

FAA's Determination

    We are proposing this NPRM because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This NPRM would require inspecting the fuel nozzle-to-fuel supply 
manifold interface for evidence of leaks and replacing hardware in 
cases where fuel leaks are identified. This NPRM also requires 
torqueing certain B-nuts to the specified requirement.

Differences Between This Proposed AD and the Service Information

    PW ASB No. PW4G-100-A73-44 uses calendar dates for compliance time. 
This NPRM uses cycles. Using cycles from the effective date of the AD 
supports the intent of the ASB and ensures adequate compliance time 
after the effective date of the AD.

Costs of Compliance

    We estimate that this proposed AD would affect about 72 engines 
installed on airplanes of U.S. registry. The average labor rate is $85 
per hour. We estimate that parts replacement will cost about $1,356 per 
engine. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $391,392.

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

unless already done.
    (1) Within 800 flight hours after the effective date of this AD, 
and within every 800 hours since last inspection thereafter, inspect 
all fuel nozzle-to-fuel supply manifold interfaces for evidence of 
fuel leaks, soot, and coke formation. Use the Accomplishment

dated October 10, 2014 to do the replacement.

(f) Mandatory Terminating Action

    (1) Inspect all fuel nozzle-to-fuel supply manifold interfaces 
for fuel leaks, soot, and coke formation, replace hardware that 
fails inspection, and re-torque all fuel nozzle-to-fuel supply 
manifold B-nuts as follows:

date of this AD, before accumulating another 650 cycles, not to 
exceed 1,900 cycles.
    (ii) For engines with 1,500 cycles or more, but fewer than 2,500 
cycles on the effective date of this AD, before accumulating another 
400 cycles, not to exceed 2,700 cycles.

date of this AD, before accumulating another 200 cycles.
    (2) Use the Accomplishment Instructions, Parts B through E, of 
PW ASB No. PW4G-100-A73-44, dated October 10, 2014 to do the 
inspection, replacement, and retorqueing.

(g) Definition

    For the purpose of this AD ``cycles'' is defined as cycles since 
new or cycles since the incorporation of PW SB No. PW4G-100-72-214, 
dated December 15, 2011 or SB No. PW4G-100-72-219, Revision 1, dated 
October 5, 2011.
