(d) Unsafe Condition

This AD was prompted by LP compressor blade partial airfoil release events. We are issuing this AD to prevent LP compressor blade airfoil separations, engine damage, and damage to the airplane.
(e) Actions and Compliance

Unless already done, do the following actions. (1) Ultrasonic Inspection (UI) of LP Compressor Blade

(i) After the effective date of this AD, ultrasonically inspect each LP compressor blade before the blade exceeds 3,600 cycles since new (CSN) or before further flight, whichever occurs later. Repeat the UI of the blade every 2,400 cycles since last inspection (CSLI).

(ii) For any LP compressor blade that exceeds 2,200 CSLI on the effective date of this AD, inspect the blade before exceeding 3,000 CSLI or before further flight, whichever occurs later. Thereafter, perform the repetitive inspections required by this AD.

(iii) Use paragraph 3, excluding subparagraphs 3.A.(9), 3.B.(5), 3.C.(4), 3.D.(3), 3.E.(5), 3.F.(10), and 3.G.(7), of RR Alert Non-Modification Service Bulletin (NMSB) RB.211–72–AH465, dated July 15, 2013, to perform the inspections required by this AD.
(2) Use of Replacement Blades

LP compressor blades, P/Ns FK23411, FK25441, FK25968, FW11901, FW15393, FW23643, FW23741, FW23744, KH23403, or KH23404, that have accumulated at least 3,600 CSN or 2,400 CSLI are eligible for installation if the blade has passed the UI required by this AD.
(f) Credit for Previous Actions

If you performed a UI of an affected LP compressor blade before the effective date of this AD using RR NMSB No. RB.211–72– G702, dated May 23, 2011; or RR NMSB No. RB.211–72–G872, Revision 2, dated March 8, 2013, or earlier revisions; or RR NMSB No. RB.211–72–H311, dated March 8, 2013; or Engine Manual E-Trent-1RR, Task 72–31–11– 200–806, you have met the initial inspection requirements of this AD. However, you must still comply with the repetitive 2,400 CSLI requirement of this AD. (g) Alternative Methods of Compliance (AMOCs)

The Manager, Engine Certification Office, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request.

Persons interested in being placed on a mailing list for future NPRM’s should contact the FAA’s 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 establish Class D airspace within a 4.2-mile radius of Allen C Perkinson Blackstone Army Airfield, Blackstone, VA, and amend existing Class E airspace extending upward from 700 feet above the surface to within a 6.7-mile radius of the airfield, as well as adjust the geographic coordinates of the airfield to be in concert with the FAAs aeronautical database. This action is necessary to support the operation of the new air traffic control tower, and would enhance the safety and management of IFR operations at the airfield.

Class D and E airspace designations are published in Paragraphs 5000 and 6005 respectively, of FAA Order 7400.9X, dated August 7, 2013, and effective September 15, 2013, which is incorporated by reference in 14 CFR 71.1. The Class D and E airspace designations listed in this document will 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 is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, would 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 proposed 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 proposed regulation is within the scope of that authority as it would establish Class D and amend Class E airspace at Allen C Perkinson Blackstone Army Airfield, Blackstone, VA.

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures’’ prior to any FAA final regulatory action. Lists of Subjects in 14 CFR Part 71

Airspace, Incorporation by reference, Navigation (air). The Proposed Amendment

In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR part 71 as follows:
