Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) (the

‘‘ second supplemental NPRM ’’ ) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That second SNPRM was published in the Federal Register on January 20, 2011 (76 FR 3564). That second SNPRM proposed to require inspecting the fuselage surface for corrosion and cracking behind the external adapter plate of the antennae installation, and repair if necessary.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Explanation of Change to Applicability

We have revised the applicability of the supplemental NPRM to identify model designations as published in the most recent type certificate data sheet for the affected models.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD with the change described previously. We also determined that this change will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance

We estimate that this AD affects 201 airplanes of U.S. registry. The inspection will take about 4 work-hours per airplane, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $68,340, or $340 per airplane. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. 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.

We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701:

‘‘ General requirements. ’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(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),

(3) Will not affect intrastate aviation in Alaska, and

(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. 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 FAA amends 14 CFR part 39 as follows:

### Amendment of Class E Airspace; Terre **Haute, IN**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Final rule.

**SUMMARY** 

### : This action amends Class E airspace at Terre Haute, IN, to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Union Hospital Heliport, Terre Haute, IN. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the heliport.

**DATES** 

### : Effective date: 0901 UTC, June 30, 2011. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION** 

### : History

On January 31, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend Class E airspace for Terre Haute, IN, creating additional controlled airspace at Union Hospital Heliport (76 FR 5302) Docket No. FAA–2010–1034. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraph 6005 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 E airspace designations listed in this document will be published subsequently in the Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by amending Class E airspace extending upward from 700 feet above the surface to accommodate the new COPTER RNAV (POINT-IN-SPACE) standard instrument approach procedures at Union Hospital Heliport, Terre Haute, IN. This action will enhance the safety and management of IFR operations at the heliport.

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. Therefore, this regulation: (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 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 Title 49 of the U.S. Code. Subtitle 1, 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 creates controlled airspace at Union Hospital Heliport, Terre Haute, IN. List of Subjects in 14 CFR Part 71
