Sunset Review (2012); Correction 

AGENCY: Agricultural Marketing Service, 

USDA. 

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).

tkelley on DSK3SPTVN1PROD with RULES
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. 

We must receive comments on this 

AD by September 13, 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 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 146 / Monday, July 30, 2012 / Rules and Regulations 44431 

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 also 

estimate 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.

(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 in 

rough 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. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance

Airworthiness Directives; Gulfstream 

Aerospace LP (Type Certificate 

Previously Held by Israel Aircraft 

Industries, Ltd.) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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://

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.
