Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2012– 0197, dated September 25, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Two reports have been received of a broken P/N 20 31 211 propeller shaft on a Solo 2350 C engine. The results of the investigation showed that the failures were due to a material defect, most likely caused by a manufacturing error.

This condition, if not detected and corrected, could lead to failure of the shaft and detachment of the propeller from the aeroplane, which, depending on the flight conditions, could result in reduced control of the aeroplane, or injury to persons on the ground.

For the reasons described above, this AD requires a one-time inspection (magnetic particle or dye penetrant) of the affected propeller shafts to detect cracks and, depending on findings, replacement of the propeller pulley assembly (module) with a serviceable module. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Solo Kleinmotoren GmbH has issued Service Bulletin Nr. 4603–13, Issue 1, dated September 24, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.


### 71360 Federal Register / Vol. 77, No. 231 / Friday, November 30, 2012 / Proposed Rules

Costs of Compliance

We estimate that this proposed AD will affect 2 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $170, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $197, for a cost of $282 per product. We have no way of determining the number of products that may need these actions. 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

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the 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, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

(e) Reason

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a material defect within the propeller shaft, most likely caused by a manufacturing error. We are issuing this AD to prevent failure of the propeller shaft and detachment of the propeller, which could result in reduced control of the aircraft or injury to persons on the ground.
(f) Actions and Compliance

Unless already done, do the following actions:

(1) Within 25 hours time-in-service (TIS) after the effective date of this AD or 6 months after the effective date of this AD, whichever occurs first, remove the propeller pulley assembly (module) from the engine and inspect the transition region of the part number (P/N) 20 31 211 shaft following Solo Kleinmotoren GmbH Service Bulletin Nr. 4603–13, Issue 1, dated September 24, 2012.

(2) If, during the inspection required by paragraph (f)(1) of this AD, cracks are detected in the P/N 20 31 211 shaft, before further flight, do the following:

(i) Replace the P/N 20 31 211 shaft with an airworthy P/N 20 31 211 shaft; or

(ii) Replace the propeller pulley assembly (module) with an airworthy propeller pulley assembly (module).
(g) Other FAA AD Provisions

You may review the public docket containing the proposal, any comments received and any final disposition in person in the Dockets Office (see

**ADDRESSES** section for address and phone number) between 9:00 a.m. and 5:00 p.m., Monday through Friday, except Federal holidays. An informal docket may also be examined during normal business hours at the office of the Central Service Center, 2601 Meacham Blvd., Fort Worth, TX 76137.

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

This action proposes to amend Title 14, Code of Federal Regulations (14 CFR), Part 71 by modifying Class E airspace extending upward from 700 feet above the surface for new standard instrument approach procedures at George L. Scott Municipal Airport, West Union, IA. Airspace reconfiguration is necessary due to the decommissioning of the West Union NDB and the cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of IFR operations at the airport.

Class E airspace areas are published in Paragraph 6005 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 would 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 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 would amend controlled airspace at George L. Scott Municipal Airport, West Union, IA.

Environmental Review

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. List of Subjects in 14 CFR Part 71
