List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the Federal Aviation Administration 

amends 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 Amendment 39–14729 (71 FR 

49335, August 23, 2006), and by adding 

a new airworthiness directive, 

Amendment 39–14959, to read as 

follows: 

2007–04–26 Pratt & Whitney: Amendment 

39–14959. Docket No. FAA–2006–24034; 

Directorate Identifier 2006–NE–05–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 2, 2007. 

Affected ADs 

(b) This AD supersedes AD 2006–17–08, 

Amendment 39–14729. 

Applicability 

(c) This AD applies to Pratt & Whitney 

PW4077D, PW4084D, PW4090, and PW4090–

3 turbofan engines that were: 

(1) Reassembled with a previously used 

original equipment manufacturer (OEM) or 

part manufacturer approval (PMA) high 

pressure compressor (HPC) exit inner brush 

seal pack; and 

(2) Reassembled with a new or refurbished 

OEM or PMA HPC exit diffuser air seal inner 

land. 

(d) These engines are installed on, but not 

limited to, Boeing 777 airplanes. 

Unsafe Condition 

(e) This AD supersedure results from a 

request to include PMA HPC exit inner and 

outer brush seal packs and to include the 

engines with PMA parts already installed, in 

the AD. This AD action is the result of a 

report of oil leaking into the high pressure 

turbine (HPT) interstage cavity and igniting, 

leading to an engine case penetration and 

engine in-flight shutdown. We are issuing 

this AD to prevent uncontained engine 

failure, damage to the airplane, and injury to 

passengers. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed at the 

following compliance times, unless the 

actions have already been done. 

(g) Replace the HPC exit inner and outer 

brush seal packs with OEM or FAA-approved 

PMA new HPC exit inner and outer brush 

seal packs, or an OEM or FAA-approved 

PMA new HPC exit brush seal assembly, as 

follows: 

(1) By 3,000 cycles-in-service (CIS) since a 

used HPC exit inner brush seal pack and a 

new or refurbished HPC exit diffuser air seal 

land were installed in the engine, or by 

March 31, 2007, whichever occurs later; 

however 

(2) If on March 31, 2007, the used HPC exit 

inner brush seal pack coupled with a new or 

refurbished HPC exit diffuser air seal inner 

land assembly has not accumulated 3,000 

CIS, then by 3,000 CIS, or December 31, 

2008, whichever occurs first. 

Used Part Prohibition 

(h) Engine reassembly with used OEM or 

used FAA-approved PMA HPC exit inner and 

outer brush seal packs with OEM or FAAapproved PMA new HPC exit inner and outer 

brush seal lands, is prohibited. 

(i) Information on replacing HPC exit inner 

and outer brush seal packs can be found in 

the Pratt & Whitney Alert Service Bulletin 

No. PW4G–112–A72–280, Revision 2, dated 

January 12, 2007, and in the engine overhaul 

manual. 

Alternative Methods of Compliance 

(j) The Manager, Engine Certification 

Office, has the authority to approve 

alternative methods of compliance for this 

AD if requested using the procedures found 

in 14 CFR 39.19. 

Related Information 

(k) Pratt & Whitney Alert Service Bulletin 

No. PW4G–112–A72–280, Revision 2, dated

Modification of Class D Airspace; Luke 

Air Force Base, AZ 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action modifies Class D 

airspace at Luke Air Force Base (LUF), 

AZ. This modification is necessary to 

contain and protect circling maneuvers 

for Category E aircraft executing these 

maneuvers in conjunction with 

Standard Instrument Approach 

Procedures (SIAPs) at the airport. 

DATES: Effective Date: 0901 UTC, May 

10, 2007. The Director of the Federal 

Register approves this incorporation by 

reference action under title 1, Code of 

Federal Regulations, part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

History 

On December 7, 2006, the FAA 

published in the Federal Register (71 

FR 70910) a notice of proposed 

rulemaking to revise the Class D 

airspace at Luke Air Force Base, AZ. 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on this 

proposal to the FAA. On January 11, 

2007, a notice of proposed rulemaking 

correction was published in the Federal 

Register (72 FR 1301), changing the 

legal description to better describe the 

requisite airspace. No comments were 

received. This modification is the same 

as that proposed in the notice. Class D 

airspace areas are published in 

Paragraph 5000 of FAA Order 7400.9P 

dated September 1, 2006, and effective 

September 15, 2006, which is 

incorporated by reference in 14 CFR 

71.1. The Class D airspace designation 

listed in this document will be 

published subsequently in the Order. 


ycherry on PROD1PC64 with RULES
8266 Federal Register / Vol. 72, No. 37 / Monday, February 26, 2007 / Rules and Regulations 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

modifying the Class D airspace area for 

Luke Air Force Base, AZ. This 

modification is necessary to contain and 

protect circling maneuvers for Category 

E aircraft executing these maneuvers in 

conjunction with Standard Instrument 

Approach Procedures (SIAPs) at the 

airport. This action modifies the 

existing LUF Class D airspace to extend 

upward from the surface to, but not 

including, 4000 feet mean sea level 

(MSL) and within a 5.6-mile radius of 

Luke AFB from a point intersecting the 

northwest portion of the Goodyear Class 

D airspace clockwise to a point 

intersecting the northern portion of the 

Glendale Class D airspace; and within a 

4.4 mile radius of Luke AFB from the 

intersection of the southern portion of 

the Glendale Class D airspace clockwise 

to the intersection of the Goodyear Class 

D airspace; and excluding that portion 

within the Glendale, AZ, and Goodyear, 

AZ Class D airspace areas. 

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. Therefor, this regulation: (1) Is 

not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under Department of 

Transportation 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.
