**ACTION :**  Correcting amendments.

**SUMMARY :**  This document contains a correction to the final regulations published on June 6, 2012 (77 FR 33290). These regulations pertain to the 2012 Sunset Review of substances on the U.S. Department of Agriculture’s (USDA) National List of Allowed and Prohibited Substances (National List). A technical error was inadvertently published in the final rule and requires correction. This document corrects the final regulations by revising the listing for ‘‘colors’’ at 7 CFR 205.606(d).

**DATES :**  Effective on July 30, 2012.

**FOR FURTHER INFORMATION CONTACT :**  Melissa Bailey, Ph.D., Director, Standards Division, Telephone: (202) 720–3252; Fax: (202) 205–7808.

**SUPPLEMENTARY INFORMATION :**  On June 6, 2012, the Agricultural Marketing Service (AMS) published a final rule (77 FR 33290) to address the 2012 Sunset Review of substances on the U.S. Department of Agriculture’s (USDA) National List of Allowed and Prohibited Substances (National List).

This rule amended the restrictive annotation to the listing for colors at 7 CFR 205.606(d). As published, the modification to the introductory text for this listing for colors at § 205.606(d) inadvertently removed paragraphs (d)(1) through (d)(19). These paragraphs are necessary to identify the specific nonorganic colors that can be used as ingredients in processed products labeled as ‘‘organic’’ if organic forms are not commercially available. This document corrects the final regulations by reinserting paragraphs (d)(1) through (19). List of Subjects in 7 CFR Part 205

### 44430 Federal Register / Vol. 77, No. 146 / Monday, July 30, 2012 / Rules and Regulations

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for various aircraft equipped with Rotax Aircraft Engines 912 A series engine. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a deviation in the manufacturing process of fuel hoses installed on the pressure side of part number 893114 fuel pumps. The fuel hoses may not be fuel resistant, which could lead to detachment of particles from the fuel hose and cause irregularities in the carburetor function and possibly result in rough engine operation, engine misfire, in-flight engine shutdown, and forced landing. We are issuing this AD to require actions to address the unsafe condition on these products.

**DATES :**  This AD is effective August 14,
2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 14, 2012.

**SUPPLEMENTARY INFORMATION :** 

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– 0097R1, dated June 1, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Reports from the field confirmed a noncompliance of pressure side fuel hoses installed on certain P/N 893114 fuel pumps, which may have resulted in a latent defect on a limited number of engines. The affected fuel hoses may not be fuel resistant in accordance with the specification.

This condition, if not corrected, could lead to detachment of particles from the fuel hose and irregularities in the carburettor function, possibly resulting in in-flight engine shutdown and forced landing, damage to the aeroplane and injury to occupants.

To address this potential unsafe condition, EASA issued Emergency AD 2012–0093–E to require the replacement of the pressure side fuel hose on certain fuel pumps, identified by P/N 893114. That AD also prohibited installation of an affected engine on an aeroplane, unless the fuel pump installation of that engine had been corrected as required by the AD.

Since that AD was issued, the relevant BRP–Powertrain Alert Service Bulletin (ASB) ASB–912–061 has been revised (R1) to correct the list of affected P/N 893114 fuel pumps, identified by s/n. As some of these pumps (including potentially defective hoses) have been delivered as spares, they could also be installed on other engines than those specified by s/n in BRP–Powertrain ASB–912–061R1.

For the reasons described above, this AD retains the requirements of EASA Emergency AD 2012–0093–E, which is superseded, expands the Applicability to all Rotax 912 series engines and corrects Table 1—Affected P/N 893114 fuel pumps. In addition, 2 aeroplane types have been removed from the Applicability of this AD: Aeromot AMT 300 Turbo Super Ximango and Stemme S10 VT have a Rotax 914 engine installed, not a Rotax 912.

This AD has been revised to correct Table 1 of the Required Action(s) and Compliance Times(s) section, which did not contain all affected s/n fuel pumps. This AD requires replacement of the pressure side fuel hose on the part number (P/N) 893114 fuel pump. This AD also prohibits the installation of an affected engine unless the pressure side fuel hose on the P/N 893114 fuel pump has been replaced. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Rotax Aircraft Engines BRP has issued Alert Service Bulletin ASB–912–061R1, dated May 31, 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 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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA’s 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 detachment of particles from the fuel hose on the pressure side of the fuel pump could cause engine damage and result in in-flight engine shutdown. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘Docket No. FAA–2012–0765; Directorate Identifier 2012–CE–028– AD’’ at the beginning of your comments. We specifically invite comments on the


### 44431 Federal Register / Vol. 77, No. 146 / Monday, July 30, 2012 / Rules and Regulations

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. Costs of Compliance

We estimate that this AD will affect 50 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. Required parts will cost about $300 per product.

Based on these figures, we estimate the cost of the AD on U.S. operators to be $27,750, or $555 per product. 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 that 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, 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 AD:

2012–15–01 Various Aircraft: Amendment 39–17130; Docket No. FAA–2012–0765; Directorate Identifier 2012–CE–028–AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective August 14, 2012.

(b) Affected ADs

(e) Reason

This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a deviation in the manufacturing process of fuel hoses installed on the pressure side of P/N 893114 fuel pumps. The fuel hoses may not be fuel resistant, which could lead to detachment of particles from the fuel hose and cause irregularities in the carburetor function. We are issuing this AD to prevent failure of the fuel hose on the pressure side of the P/N 893114 fuel pump, which could result inrough engine operation, engine misfire, inflight engine shutdown, and forced landing.
(f) Actions and Compliance

Unless already done, do the following actions in accordance with Rotax Aircraft Engines BRP Alert Service Bulletin ASB– 912–061R1, dated May 31, 2012.

(1) Before further flight after August 14, 2012 (the effective date of this AD), replace the pressure side fuel hose on the P/N 893114 fuel pump.

(2) As of August 14, 2012 (the effective date of this AD), do not install a P/N 893114 fuel pump on any engine, unless the pressure side fuel hose of that fuel pump has been replaced as required in paragraph (f)(1) of this AD.

(3) As of August 14, 2012 (the effective date of this AD), do not install on any airplane a Rotax 912 A series engine, unless the fuel pump installation of that engine has been corrected as required in paragraph (f)(1) of this AD.

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Astra SPX, 1125 Westwind Astra, and Gulfstream 100 airplanes. This AD was prompted by a report indicating that sponge rubber padding was found between wheel well fuel lines and electrical harnesses. This AD requires inspecting for the presence of sponge rubber padding and for proper separation of the fuel lines and electrical harnesses in the wheel well area, and corrective actions if necessary. We are issuing this AD to detect and correct corrosion or chafing of the fuel lines, which could result in fuel leakage and possible fire in the wheel well area.

**DATES :**  This AD becomes effective September 4, 2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 4, 2012.

**ADDRESSES :**  You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC. **FOR FURTHER INFORMATION CONTACT :**  Tom Groves, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, Washington 98057–3356; telephone (425) 227–1503; fax (425) 227–1149.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 8, 2010 (75 FR 76317). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Sponge rubber padding used to provide separation between wheel well fuel lines and electrical harnesses was discovered during fleet maintenance. Use of this type of padding for this purpose is not approved as it is liable to cause corrosion of the fuel lines. Unless steps are taken to remove this padding and install approved separation means, fuel lines may be damaged by corrosion and/or chafing resulting in an unsafe condition due to fuel leakage[, which could result in a fire] in the wheel well area. Corrective actions include installing loop clamps to correct improper separation and removing sponge rubber padding, and repair or replacement of any corroded or chafed fuel lines found after sponge rubber padding removal. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comments received. Requests To Include Additional Inspection Area

Gulfstream Aerospace Corporation (Gulfstream) requested that the inspection area be expanded to include tube assemblies outside of the wheel well area that have also been found to have sponge rubber padding and corrosion beneath the padding. Gulfstream stated that the padding with corrosion beneath has been found on four tube assemblies outside of the wheel well area specified in the NPRM (75 FR 76317, December 8, 2010) and Gulfstream Service Bulletin 100–28– 297, dated January 21, 2010. These four tube assemblies are part of, or an extension of, the tube assemblies identified by part number in that service bulletin, and terminate in the wing root

area.

John R. Dunn, a private citizen, stated that, upon further investigation after discovering instances of sponge rubber
