Federal Register / Vol. 75, No. 162 / Monday, August 23, 2010 / Rules and Regulations 51659 

A PW617F–E engine powered twin 

engined aircraft had recently experienced an 

uncommanded power reduction on one of its 

engines. Investigation showed that the Fuel 

Filter Bypass Valve poppet in the Fuel Oil 

Heat Exchanger (FOHE) on that engine had 

worn through the housing seat, allowing 

unfiltered fuel and debris to contaminate the 

Fuel Metering Unit (FMU), resulting in fuel 

flow drop and subsequent power reduction. 

P&WC has confirmed that this is a dormant 

failure that could result in an unsafe 

condition. 

The PW615F–A engine Fuel Filter Bypass 

Valve installation is very similar to that of 

PW617F–E, but so far there have been no 

operational abnormalities reported due to 

subject valve failure on PW615F–A engines. 

However, evaluation by P&WC has confirmed 

similar dormant failure of worn through 

poppets of the subject valve on some 

PW615F–A engine installations, which could 

affect both engines at the same time on an 

aircraft and may result in an unsafe 

condition. 

We are issuing this AD to prevent 

uncommanded power reduction, which 

could result in the inability to continue safe 

flight and safe landing. 

Actions and Compliance 

(e) Unless already done, replace the FOHE 

fuel filter bypass poppet valve with a larger 

fuel filter bypass poppet valve within 25 

hours of the effective date of the AD. Use 

paragraph 3.A. of the Accomplishment 

Instructions of Pratt & Whitney Canada Corp.

Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

A PW617F–E engine powered twin 

engined aircraft had recently experienced an 

uncommanded power reduction on one of its 

engines. Investigation showed that the Fuel 

Filter Bypass Valve poppet in the Fuel Oil 

Heat Exchanger (FOHE) on that engine had 

worn through the housing seat, allowing 

unfiltered fuel and debris to contaminate the 

Fuel Metering Unit (FMU), resulting in fuel 

flow drop and subsequent power reduction. 

Pratt & Whitney Canada Corp. issued an 

Alert Service Bulletin (ASB) No. PW600–72– 

A66019 to inspect and replace any discrepant 

valve with the same type new valve. The 

inspection results confirmed that failure of a 

worn through poppet is dormant and it can 

affect both engines at the same time that 

could result in an unsafe condition on 

PW617F–E powered aircraft. 

We are issuing this AD to prevent 

uncommanded power reduction, which 

could result in the inability to continue 

safe flight and safe landing. 

DATES: This AD becomes effective 

September 27, 2010. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD as of 

September 27, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on May 17, 2010 (75 FR 27491). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states that: 

A PW617F–E engine powered twin 

engined aircraft had recently experienced an 

uncommanded power reduction on one of its 

engines. Investigation showed that the Fuel 

Filter Bypass Valve poppet in the FOHE on 

that engine had worn through the housing 

seat, allowing unfiltered fuel and debris to 

contaminate the FMU, resulting in fuel flow 

drop and subsequent power reduction. 

Pratt & Whitney Canada Corp. issued an 

ASB No. PW600–72–A66019 to inspect and 

replace any discrepant valve with the same 

type new valve. The inspection results 

confirmed that failure of a worn through 

poppet is dormant and it can affect both 

engines at the same time that could result in 

an unsafe condition on PW617F–E powered 

aircraft. 

On November 23, 2009, Pratt & Whitney 

Canada Corp. issued an ASB No. PW600–72– 

A66021 that introduced a new fuel Filter 

Bypass Valve Assembly with an improved 

design poppet to help alleviate the subject 

poppet wear problem. This AD is issued to 

mandate replacement of the FOHE fuel filter 

bypass valve on all PW617F–E engines as per 

Pratt & Whitney Canada Corp. ASB No. 

PW600–72–A66021 instructions.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

77 engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 3.5 work-hours per engine to 

comply with this AD. The average labor 

rate is $85 per work-hour. Required 

parts will cost about $22,582 per engine. 

Based on these figures, we estimate the 

cost of the AD on U.S. operators to be 

$1,761,722. 

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 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 this AD: 

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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

SUPPLEMENTARY INFORMATION: 

History 

On Monday, June 7, 2010, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to modify the Pacific High and Low 

Control Areas (75 FR 32119). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal. No 

comments were received. The proposed 

legal description contained the 

exclusion of active warning area 

airspace; it was brought to our attention 

that it was not necessary to exclude 

active warning areas in the description 

since active warning areas are excluded 

by policy. With this exception, this 

amendment is the same as that proposed 

in the NPRM. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

modifying the Pacific High and Low 

Offshore Airspace Areas, by extending 

the present airspace boundaries further 

southeast of the current location to the 

Mexico FIR capturing pockets of 

uncontrolled airspace off the California 

coast. This modification will allow the 

application of domestic ATC separation 

procedures in lieu of ICAO separation 

and enhance system capacity and allow 

for more efficient utilization of that 

airspace. 

Offshore airspace areas are published 

in paragraph 2003 and 6007, 

respectfully, of FAA Order 7400.9T 

signed August 27, 2009 and effective 

September 15, 2009, which is 

incorporated by reference in 14 CFR 

71.1. The offshore airspace listed in this 

document will be published 

subsequently in the Order. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under Department of 

Transportation (DOT) Regulatory 

Policies and Procedures (44 FR 11034; 

February 26, 1979); and (3) does not 

warrant preparation of a regulatory 

evaluation as the anticipated impact is 

so minimal. Since this is a routine 

matter that will only affect air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. 

This rulemaking is promulgated 

under the authority described in 

Subtitle VII, Part A, Subpart I, Section 

40103. Under that section, the FAA is 

charged with prescribing regulations to 

assign the use of the airspace necessary 

to ensure the safety of aircraft and the 

efficient use of airspace. This regulation 

is within the scope of that authority as 

it modifies the high and low offshore 

airspace areas off the coast of California. 

ICAO Considerations 

As part of this action relates to 

navigable airspace outside the United 

States, this notice is submitted in 

accordance with the ICAO International 

Standards and Recommended Practices. 

The application of International 

Standards and Recommended Practices 

by the FAA, Office of System 

Operations Airspace and AIM, Airspace 

and Rules Group, in areas outside the 

United States domestic airspace, is 

governed by the Convention on 

International Civil Aviation. 

Specifically, the FAA is governed by 

Article 12 and Annex 11, which pertain 

to the establishment of necessary air 

navigational facilities and services to 

promote the safe, orderly, and 

expeditious flow of civil air traffic. The 

purpose of Article 12 and Annex 11 is 

to ensure that civil aircraft operations 

on international air routes are 

performed under uniform conditions. 

The International Standards and 

Recommended Practices in Annex 11 

apply to airspace under the jurisdiction 

of a contracting State, derived from 

ICAO. Annex 11 provisions apply when 

air traffic services are provided and a 

contracting State accepts the 

responsibility of providing air traffic 

services over high seas or in airspace of 

undetermined sovereignty. A 

contracting State accepting this 

responsibility may apply the 

International Standards and 

Recommended Practices that are 

consistent with standards and practices 

utilized in its domestic jurisdiction. 

In accordance with Article 3 of the 

Convention, State-owned aircraft are 

exempt from the Standards and 

Recommended Practices of Annex 11. 

The United States is a contracting State 

to the Convention. Article 3(d) of the 

Convention provides that participating 

State aircraft will be operated in 

international airspace with due regard 

for the safety of civil aircraft. Since this 

action involves, in part, the designation 

of navigable airspace outside the United 

States, the Administrator is consulting 

with the Secretary of State and the 

Secretary of Defense in accordance with 

the provisions of Executive Order 

10854.
