9504 Federal Register / Vol. 73, No. 35 / Thursday, February 21, 2008 / Proposed Rules 

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): 

Rolls-Royce plc: Docket No. FAA–2007–

0078; Directorate Identifier 2007–NE–

40–AD. 

Comments Due Date 

(a) We must receive comments by March 

24, 2008. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Rolls-Royce plc (RR) 

models RB211–535E4 series, RB211–535E4–

B series, RB211–535E4–C series, RB211–

535C series, RB211–524 series, and RB211–

22B series turbofan engines. These engines 

are installed on, but not limited to, Boeing 

747, 757, and 767, Lockheed L–1011, and 

Tupulev Tu204 airplanes. 

Reason 

(d) European Aviation Safety Agency AD 

2006–0180, dated June 26, 2006, AD 2006–

0181, dated June 26, 2006, and AD 2006–

0182, dated June 28, 2006, state: 

High pressure (HP) turbine discs recently 

inspected in accordance with the Engine 

Manual have exhibited cracks in the disc rim. 

The discs have failed to meet the inspection 

acceptance criteria and have been returned to 

Rolls-Royce for engineering investigation. 

This investigation has concluded that the 

cracks have resulted from scores within the 

cooling air holes in the disc rim that could 

have been introduced during new part 

manufacture or during overhaul of the disc. 

The engineering investigation has concluded 

that if this cracking was undetected then it 

could result in uncontained disc failure and 

a potential unsafe condition for the aircraft. 

We are issuing this AD to prevent 

uncontained disc failure, possibly resulting 

in damage to the airplane. 

Actions and Compliance 

(e) Unless already done, perform an initial 

eddy current inspection (ECI) of the HP 

turbine disc air cooling holes. Information on 

ECI of HP turbine disc cooling holes can be 

found in RR Engine Overhaul Process

Office of Rulemaking, (202) 267–9677, 

to request a copy of Advisory Circular 

No. 11–2A, Notice of Proposed 

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

The FAA is considering an 

amendment to Title 14, Code of Federal 

Regulations (14 CFR) part 71 to modify 

Class E airspace at Waynesburg, PA. A 

new Area Navigation (RNAV) Global 

Position System (GPS) Runway (RWY) 

09 Standard Instrument Approach 

Procedure (SIAP) has been developed at 

the Green County Airport. Controlled 

airspace, known as Class E5 airspace, 

extending upward from 700 feet or more 

above the surface of the Earth, is 

required for instrument flight rule 

operations and to encompass all SIAPs 

to the extent possible. Although Class E 

airspace exists at the airport, it is of 

insufficient size and needs to be 

increased from a 6-mile radius to an 8.3- 

mile radius to incorporate the SIAP. 

Class E airspace designations for 

airspace areas extending upward from 

700 feet or more above the surface of the 

Earth are published in Paragraph 6005 

of FAA Order 7400.9R, signed August 

15, 2007, and effective September 15, 

2007, which is incorporated by 

reference in 14 CFR 71.1. The Class E 

airspace designation listed in this 

document would be published 

subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore, (1) is not a ‘‘significant 

regulatory action’’ under Executive 

Order 12866; (2) is not a ‘‘significant 

rule’’ under 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 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 the 

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 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 Class E Airspace at 

Waynesburg, PA.

Approval and Promulgation of Air 

Quality Implementation Plans; Maine; 

Open Burning Rule 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to approve 

a State Implementation Plan (SIP) 

revision submitted by the State of 

Maine. This revision limits open 

burning of construction and demolition 

debris to on-site burning for the disposal 

of wood wastes and painted and 

unpainted wood, and adds restrictions 

to open burning conducted for training, 

research and recreational purposes. The 

revised rule also defines which openburning recreational activities do not 

require a permit, such as residential use 

of outdoor grills and fireplaces, and 

recreational campfires while the ground 

is covered in snow. The revised rule 

eliminates provisions that allowed 

permits to be issued for open burning of 

rubbish where no rubbish collection is 

available or ‘‘reasonably located’’ and 

where ‘‘there is no other suitable 

method for disposal.’’ In addition, the 

revised rule includes a reference to 

reasonable precautions required by 

Maine statute 38 MRSA section 1296 to 

prevent the introduction of lead into the 

environment from lead-based paint. 

This action will have a beneficial effect 

on air quality in Maine by reducing 

emissions of particulate matter, air 

toxics, and other pollutants, especially 

from the burning of lead-painted wood, 

plastics, metals, and other non-wood 

materials. This action is being taken in 

accordance with the Clean Air Act.
