Note 1 to paragraph (g) of this AD: The maintenance program revision required by paragraph (g) of this AD may be done by inserting a copy of Bombardier CL–600–2B19 TR 2A–48, dated July 6, 2012, into Appendix A—Certification Requirements, of Part 2, Airworthiness Requirements, of the Bombardier CL–600–2B19 MRM. When this TR has been included in general revisions of the MRM, the general revisions may be inserted in the MRM, provided the relevant information in the general revision is identical to that in Bombardier CL–600–2B19 TR 2A–48, dated July 6, 2012.

(h) Initial Task Compliance Times

For the inboard and outboard flap actuators identified in Bombardier CL–600–2B19 TR 2A–48, dated July 6, 2012, to Appendix A— Certification Requirements, of Part 2, Airworthiness Requirements, of the Bombardier CL–600–2B19 MRM, the initial compliance times for the tasks specified in Bombardier CL–600–2B19 TR 2A–48, dated July 6, 2012, are at the applicable times specified in paragraphs (h)(1) through (h)(4) of this AD.

(1) For flap actuators that have accumulated less than 6,000 flight cycles as of the effective date of this AD, before the accumulation of 10,000 flight cycles on the flap actuator.

(2) For flap actuators that have accumulated 6,000 or more flight cycles but less than 10,000 flight cycles as of the effective date of this AD, within 4,000 flight cycles after the effective date of this AD, but no later than 12,000 flight cycles on the flap

actuator.

(3) For flap actuators that have accumulated 10,000 or more flight cycles but less than or equal to 12,000 flight cycles as of the effective date of this AD, within 2,000 flight cycles after the effective date of this AD, but no later than 13,000 flight cycles on the flap actuator.

(4) For flap actuators that have accumulated more than 12,000 flight cycles as of the effective date of this AD, within 1,000 flight cycles after the effective date of this AD.
(i) Repetitive Compliance Time

Where Bombardier CL–600–2B19 TR 2A– 48, dated July 6, 2012, to Appendix A— Certification Requirements, of Part 2, Airworthiness Requirements, of the Bombardier CL–600–2B19 MRM, specifies a task interval of 10,000 flight cycles or 144 months, the task interval is 10,000 flight cycles.
(j) No Alternative Actions and Intervals

After accomplishing the revision required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k) of this
AD.

(k) Other FAA AD Provisions

The following provisions also apply to this

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 E surface airspace at Leesburg, VA, providing the controlled airspace required to aid Potomac TRACON in the safe and orderly flow of air traffic at Leesburg Executive Airport. Controlled airspace extending upward from the surface within a 6-mile radius of the airport would be established for the safety and management of IFR operations.

Class E surface airspace designations are published in Paragraph 6002 of FAA Order 7400.9W, dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation 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 E surface airspace at Leesburg Executive Airport, Leesburg,
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
