55298 Federal Register / Vol. 76, No. 173 / Wednesday, September 7, 2011 / Proposed Rules 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model DHC–8–301, –311, and –315 

airplanes, certificated in any category; having

support brackets that were manufactured 

using sheet metal have been found cracked 

on DHC–8 Series 300 aircraft. Investigation 

revealed that the failure of the support 

bracket was due to fatigue. Failure of the 

aileron terminal quadrant support bracket 

could result in an adverse reduction of 

aircraft roll control. 

* * * * * 

These conditions could result in loss of 

control of the airplane.

(202) 267–8783. Communications must

notice. Persons interested in being 

placed on a mailing list for future 

NPRMs 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, Class E surface area 

airspace and amend Class E airspace 

extending upward from 700 feet above 

the surface at Hernando County Airport, 

Brooksville, FL. Controlled airspace is 

necessary to support the operation of 

the new air traffic control tower, and 

new standard instrument approach 

procedures, and would enhance the 

safety and management of aircraft 

operations at the airport. Also, to be in 

concert with the FAAs aeronautical 

database, this action would adjust the 

geographic coordinates of the airport. 

Class D and E airspace designations 

are published in Paragraphs 5000, 6002, 

and 6005 respectively, of FAA Order 

7400.9U, dated August 18, 2010, and 

effective September 15, 2010, 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 

proposes to establish and amend 

controlled airspace at Hernando County 

Airport, Brooksville, FL.

The Proposed Amendment 

In consideration of the foregoing, the 

Federal Aviation Administration
