Airworthiness Directives; Pratt & 

Whitney Canada Corp. Turboprop 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2014–14– 

02, which applies to certain Pratt & 

Whitney Canada Corp. (P&WC) PW120, 

PW121, PW121A, PW124B, PW127, 

PW127E, PW127F, PW127G, and 

PW127M turboprop engines. AD 2014– 

14–02 requires removal of the O-ring 

seal from the fuel manifold fitting. Since 

we issued AD 2014–14–02, we received 

reports of fuel seepage past the metal-tometal sealing surfaces of the fuel nozzle 

and fuel manifold flow adapter. This 

proposed AD would require 

replacement of the fuel nozzle and the 

fuel manifold flow adapter. We are 

proposing this AD to prevent in-flight 

fuel leakage, engine fire, damage to the 

engine, and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by August 3, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Discussion 

On June 30, 2014, we issued AD 

2014–14–02, Amendment 39–17896 (79 

FR 39958, July 11, 2014), (‘‘AD 2014– 

14–02’’), for certain P&WC PW120, 

PW121, PW121A, PW124B, PW127, 

PW127E, PW127F, PW127G, and 

PW127M turboprop engines. AD 2014– 

14–02 requires removal of the O-ring 

seal from the fuel manifold fitting. AD 

2014–14–02 resulted from reports of 

fuel leaks at the interface between the 

fuel manifold and the fuel nozzle that 

resulted in engine fire. We issued AD 

2014–14–02 to prevent in-flight fuel 

leakage, engine fire, damage to the 

engine, and damage to the airplane. 

Actions Since AD 2014–14–02 Was 

Issued 

Since we issued AD 2014–14–02, we 

have received reports of fuel seepage 

past the metal to metal sealing surfaces 

of the fuel nozzle and fuel manifold 

flow adapter. The manufacturer has 

since redesigned the fuel manifold flow 

adapter to prevent in-flight fuel leakage. 

This redesign incorporates new internal 

diameters on the fuel manifold adapters 

and the fuel nozzles. 

Related Service Information Under 1 

CFR Part 51 

We reviewed P&WC SB No. PW100– 

72–21861, dated November 21, 2014, 

which identifies the final fuel nozzle 

configuration. 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 of this NPRM. 

Other Related Service Information 

P&WC SB No. PW100–72–21861, 

dated November 21, 2014, refers to the 

following additional SBs that provide 

the final fuel nozzle configuration: 

P&WC SB No. PW100–72–21803, 

Revision No. 5, dated November 21, 

2014, P&WC SB No. PW100–72–21860, 

Revision No. 2, dated November 21, 

2014, and P&WC SB No. PW100–72– 

21841, Revision No. 3, dated December 

22, 2014. This service information is 

available by the means identified in the 

ADDRESSES section of this NPRM. 

FAA’s Determination 

We are proposing this AD 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 proposed AD would require 

replacement of the fuel nozzle and the 

fuel manifold flow adapter. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 150 engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 2.5 

hours per engine to perform the 

replacement required by this proposed 

AD. The average labor rate is $85 per 

hour. The cost of a fuel nozzle manifold 

replacement is $146,594. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$22,020,975.

31326 Federal Register / Vol. 80, No. 105 / Tuesday, June 2, 2015 / Proposed Rules 

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 have 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 that the 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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 

removing Airworthiness Directive (AD) 

2014–14–02, Amendment 39–17896 (79

(d) Unsafe Condition 

This AD was prompted by reports of fuel 

seepage past the metal-to-metal sealing 

surfaces of the fuel nozzle and fuel manifold 

flow adapter. We are issuing this AD to 

prevent in-flight fuel leakage, engine fire, 

damage to the engine, and damage to the 

airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. Within 1,500 flight hours after the 

effective date of this AD, or at the next engine 

shop visit, whichever occurs first: 

(1) Remove the O-ring seal from the fuel 

manifold fitting, 

(2) Remove fuel manifold flow adapter, 

part number (P/Ns) 3059754–01, 3059757–

manifold gasket, P/N 3079354–01, are not 

eligible for installation in any engine. 

(g) Definition 

For the purpose of this AD, an engine shop 

visit is the induction of an engine into the 

shop for maintenance involving the 

separation of pairs of major mating engine 

flanges. The separation of engine flanges 

solely for the purpose of transportation 

without subsequent engine maintenance does 

not constitute an engine shop visit.
