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.

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 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 146 / Monday, July 30, 2012 / Rules and Regulations 44433 

in the left wheel well, foam (sponge 

rubber padding) was found wrapped 

around tubes in the forward wing root 

areas of two airplanes along with wire 

harnesses alongside the affected tubes. 

Corrosion was also found on those 

tubes. John R. Dunn stated that neither 

of the affected wing root areas are 

mentioned in Gulfstream Service 

Bulletin 100–28–297, dated January 21, 

2010. 

We partially agree. We agree to 

investigate reports of sponge rubber 

padding use, and any subsequent 

corrosion, that occurs outside of the 

wheel well area specified in Gulfstream 

Service Bulletin 100–28–297, dated 

January 21, 2010. Depending on the 

results of the investigation, we will 

work with the airplane manufacturer to 

develop appropriate service information 

and might consider additional 

rulemaking to address these areas. We 

do not agree to change this AD to 

include the additional areas outside of 

the wheel well areas, since that would 

expand the scope of this AD and 

therefore require additional public 

review. We do not yet have sufficient 

information to justify delaying this AD 

to include those tubes. We have not 

changed the AD in this regard. 

Request To Revise Wording in 

Paragraph (g) of NPRM (75 FR 76317, 

December 8, 2010) 

Gulfstream requested that the NPRM 

(75 FR 76317, December 8, 2010) be 

revised to state that ‘‘all’’ tubes in the 

wheel well areas be inspected for the 

sponge rubber padding and corrosion 

conditions. Gulfstream stated that it has 

received reports where tube part 

numbers other than those called out in 

the service information have sponge 

rubber padding. 

We disagree to revise the wording in 

paragraph (g) of this AD to add the word 

‘‘all.’’ Gulfstream Service Bulletin 100– 

28–297, dated January 21, 2010, already 

specifies a detailed inspection in the 

wheel well area for the presence of 

sponge rubber padding without 

specifying part numbers. As noted in 

paragraph 4.A. of the Accomplishment 

Instructions of that service bulletin, this 

inspection is not limited to the fuel line 

part numbers identified in that service 

bulletin. The Accomplishment 

Instructions of that service bulletin note 

that if fuel lines other than those with 

part numbers identified in that service 

bulletin are found to have sponge rubber 

padding, then the padding must be 

removed and those affected tubes must 

also be inspected for corrosion. We have 

not revised the AD in this regard. 

Conclusion 

We reviewed the available data, 

including the comments received, 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 (75 FR 

76317, December 8, 2010) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (75 FR 76317, 

December 8, 2010). 

Differences Between This AD and the 

MCAI or Service Information 

Where Gulfstream Service Bulletin 

100–28–297, dated January 21, 2010, 

specifies to submit a photo of any 

sponge rubber padding that is found to 

the manufacturer, this AD does not 

require that action. 

Gulfstream Service Bulletin 100–28– 

297, dated January 21, 2010, instructs 

operators to contact Gulfstream if 

technical assistance is required. 

However, any deviation from the 

instructions provided in that service 

bulletin and mandated by this AD must 

be approved as an alternative method of 

compliance (AMOC) under the 

provisions of paragraph (h)(1) of this 

AD. 

Costs of Compliance 

We estimate that this AD will affect 

130 products of U.S. registry. We also 

estimate that it will take about 25 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 $100 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $289,250, or 

$2,225 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM (75 FR 76317, 

December 8, 2010), the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES
