Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to certain Alpha Aviation Concept Limited Model R2160 airplane. The NPRM was published in the Federal Register on March 3, 2014 (79 FR 11723). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI

states:

The AD is prompted by an overseas DR300/180R aircraft accident which occurred during take-off. Investigation revealed a distorted metal screen shield which grounded the ignition switch terminals and resulted in loss of engine power.

Robin aircraft manufactured prior to 1985 were fitted with ignition switches protected with a metal screen shield. With subsequent radio and electrical system improvements ignition switch shielding is no longer required, and most aircraft do not have metal screen shielded ignition switches.

This AD requires a one-time inspection of the ignition switch to determine if a metal screen shield is installed, and depending on findings, to modify or replace the ignition switch with a serviceable part. The AD prohibits the installation of a metal screen shield ignition switch on any aircraft.



### The MCAI can be found in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0130-

0002

. Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 11723, March 3, 2014) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (79 FR 11723, March 3, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 11723, March 3, 2014).
Costs of Compliance

We estimate that this AD will affect 10 products of U.S. registry. We alsoestimate that it will take about 3 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $2,550, or $255 per product.

In addition, we estimate that any necessary follow-on actions will take about 3 work-hours and require parts costing $100, for a cost of $355 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 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 this AD:

(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.
Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2012– 0130; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the **ADDRESSES**

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator,


## 26610 Federal Register / Vol. 79, No. 90 / Friday, May 9, 2014 / Rules and Regulations

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 AD:
2014–09–12 Alpha Aviation Concept Limited: Amendment 39–17847; Docket No. FAA–2014–0130; Directorate Identifier 2014–CE–005–AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective June 13, 2014.

(b) Affected ADs

None.
(c) Applicability

This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, serial numbers 001 through 378, certificated in any category.
