**SUMMARY :**  We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires an inspection of the elevator spar for cracks and, if any crack is found, either replacement with a serviceable elevator spar that is found free of cracks orrepair/modification with an FAAapproved method. This AD also requires reporting to the FAA the results of the inspection. This AD was prompted by reports of a total of nine elevator spar cracks across seven of the affected airplanes, including a crack of 2.35 inches just below the outboard hinge of the right-hand elevator. We are issuing this AD to prevent structural failure of the elevator spar due to such cracking, which could result in separation of the elevator from the airplane with consequent loss of control.

**DATES :**  This AD is effective April 4,
2011.

We must receive comments on this AD by May 19, 2011.

**SUPPLEMENTARY INFORMATION :** 

Discussion

The FAA has received a report from CPAC, Inc. describing a crack of 2.35 inches just below the outboard hinge of the right-hand elevator on a CPAC, Inc. Model 114 airplane. The Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC have the same design of the elevator spar and are all part of Type Certificate A12SO. There have been a total of nine elevator spar cracks across seven of these airplanes.

Type Certificate A12SO does not include Models 112A and 115. The Model 112A is a Rockwell ‘‘marketing

name ’’ for the Model 112. The Model 115 is a Rockwell ‘‘marketing name ’’ for the Model 114.

If not corrected, structural failure of the elevator spar could result in separation of the elevator from the airplane with consequent loss of control.

Relevant Service Information

We have included in this AD procedures for removing the elevator and inspecting the forward and aft sides of the right-hand and left-hand elevator forward spar web near and around the outboard hinge area.

FAA’s Determination

We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD requires an inspection of the elevator spar for cracks and, if any crack is found, replacement of the elevator spar with a serviceable spar that is found free of cracks or repair/ modification with an FAA-approved method. This AD also requires reporting to the FAA of the results of the inspection.

Interim Action

We consider this AD interim action. We are requiring a one-time inspection of the elevator spar with a report to the FAA of the results. We will work with the type certificate holder to evaluate that information to determine repetitive inspection intervals and subsequent terminating action. Based on this evaluation, we may initiate further rulemaking action to address the unsafe condition identified in this AD.
FAA’s Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because structural failure of the elevator spar would result in potential separation of the elevator with consequent loss of control.

Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include the docket number FAA–2011–0302 and Directorate Identifier 2011–CE–008–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.


### 18377 Federal Register / Vol. 76, No. 64 / Monday, April 4, 2011 / Rules and Regulations

Costs of Compliance

We estimate that this AD affects 773 airplanes of U.S. registry. We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection of the elevator spar ....................... 8 work-hours × $85 per hour = $680 ............. N/A $680 $525,640

Currently, there is no FAA-approved repair/modification for a cracked elevator spar. Further flight is prohibited until an FAA-approved repair/modification is submitted to the FAA and FAA-approved. A cracked elevator spar could be replaced with a serviceable one if one is available. The FAA does not have availability and cost information on serviceable elevator spars. Therefore, at this time, the FAAhas no way of determining any oncondition costs associated with cracks found in the elevator spar. 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:

**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):
2011–07–13 CPAC, Inc. (Type Certificate Formerly Held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International): Amendment 39–16650; Docket No. FAA–2011–0302; Directorate Identifier 2011–CE–008–AD.

Effective Date

(a) This AD is effective April 4, 2011.

Affected ADs

(b) None.
Applicability

(c) This AD applies to CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes, all serial numbers, certificated in any category. Type Certificate No. A12SO does not include Models 112A and 115. The Model 112A is a Rockwell ‘‘marketing name ’’ for the Model 112. The Model 115 is a Rockwell ‘‘marketing

name’’ for the Model 114. Since they are typecertificated as Model 112 and Model 114, this AD is applicable to the Models 112A and

115. Subject (d) Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 55, Stabilizers.

**14 CFR Part 71**

**[Docket No. FAA–2010–1189; Airspace Docket No. 10–AWP–19]** 

**Amendment of Class E Airspace; Taylor, AZ** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This action will amend Class E airspace at Taylor Airport, Taylor, AZ, to accommodate aircraft using the CAMBO One Departure, and the Area Navigation (RNAV) standard instrument approach procedures at Taylor Airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also corrects the airport names to Taylor Airport, and Show Low Regional Airport, respectively. Additionally, the geographic coordinates for Taylor Airport will be adjusted.

**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.

**FOR FURTHER INFORMATION CONTACT :**  Eldon Taylor, Federal Aviation Administration, Operations Support Group, Western Service Center, 1601 Lind Avenue, SW., Renton, WA 98057; telephone (425) 203–4537.

**SUPPLEMENTARY INFORMATION :**  History

On January 20, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend controlled airspace at Taylor, AZ (76 FR 3570). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Subsequent to publication, the FAA found the geographic coordinates for Taylor Airport needed to be adjusted to coincide with the FAA’s aeronautical database. This action makes the adjustment. Also, the airport names have been changed: Taylor Municipal Airport to Taylor Airport, and Show Low Municipal Airport to Show Low Regional Airport. With the exception of editorial changes, and the changes described above, this rule is the same as that proposed in the NPRM.

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 Part 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by modifying Class E airspace extending upward from 700 feet above the surface at Taylor Airport, Taylor, AZ, to accommodate IFR aircraft using the CAMBO One Departure, and the RNAV standard instrument approach procedures at the airport. This action is necessary for the safety and management of IFR operations. The geographic coordinates for Taylor Airport will be adjusted to coincide with the FAA’s aeronautical database. Also, Taylor Municipal Airport has been renamed Taylor Airport and Show Low Municipal Airport has been renamed Show Low Regional Airport.

The FAA has determined 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 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 discusses 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
