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. 

DATES: We must receive comments on 

this proposed AD by June 22, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

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-tofuel 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. 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 76 / Tuesday, April 21, 2015 / Proposed Rules 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

Pratt & Whitney: Docket No. FAA–2014– 

1130; Directorate Identifier 2015–NE– 

04–AD. 

(a) Comments Due Date 

We must receive comments by June 22, 

2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Pratt & Whitney

PW4168, and PW4168A turbofan engines that 

have incorporated either PW Service Bulletin 

(SB) No. PW4G–100–72–214, dated 

December 15, 2011 or PW SB No. PW4G– 

100–72–219, Revision 1, dated October 5, 

2011. 

(d) Unsafe Condition 

This AD was prompted by fuel nozzle-tofuel supply manifold interface fuel leaks. We 

are issuing this AD to prevent fuel leaks 

which could result in 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 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 Instructions, Part A, of PW 

Alert Service Bulletin (ASB) No. PW4G–100– 

A73–44, dated October 10, 2014 to do the 

inspections. 

(2) Replace hardware that fails an 

inspection. Use the Accomplishment 

Instructions, Part A, of PW ASB No. PW4G– 

100–A73–44, 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-tofuel supply manifold B-nuts as follows: 

(i) For engines with fewer than 1,500 

cycles on the effective 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. 

(iii) For engines with 2,500 cycles or more 

on the effective 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
