the NRC rules on compatibility and the 

potential effect on interstate commerce. 

Therefore, the petitioner requests that 

NRC consider adopting the use of GPS 

tracking as a national requirement for 

mobile or portable uses of highly 

radioactive sources. The petitioner 

further notes that a possible alterative 

would be to grant states the flexibility 

to impose more stringent requirements 

than those required under current NRC 

regulations. 

The petitioner acknowledges that 

requiring a GPS on these vehicles does 

not ensure that the radiological source 

will be found. However, the petitioner 

believes that these suggestions would 

give law enforcement a significant 

advantage.

Airworthiness Directives; SICMA Aero 

Seat 50XXX Passenger Seats 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued 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 release of smoke was experienced in the 

passenger compartment during flight after an 

overheating of a reading lights power box of 

a PN 5039201–4T SICMA seat. An analysis 

put into evidence that this overheating was 

caused by a short-circuit produced by the 

rupture of an electrical power supply 

component (PN 78147–B). It has been noticed 

that this power supply is not in compliance 

with DO 160 environmental standard. 

The short circuiting could result in 

arcing and consequent smoke or fire. 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 29, 2007. 

ADDRESSES: You may send comments by 

any of the following methods:

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. This streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This proposed AD references the 

MCAI and related service information 

that we considered in forming the 

engineering basis to correct the unsafe 

condition. The proposed AD contains 

text copied from the MCAI and for this 

reason might not follow our plain 

language principles. 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–27519; Directorate Identifier 

2007–NE–09–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD based on those comments. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal 

information you provide. We will also 

post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The Direction Generale De L’Aviation 

Civile (DGAC), which is the aviation 

authority for France, has issued French 

Airworthiness Directive F–2005–135, 

dated August 3, 2005, (EASA reference 

number 2005–6123) (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

A release of smoke was experienced in the 

passenger compartment during flight after an 

overheating of a reading lights power box of 

a PN 5039201–4T SICMA seat. An analysis 

put into evidence that this overheating was 

caused by a short-circuit produced by the 

rupture of an electrical power supply 

component (PN 78147–B). It has been noticed 

that this power supply is not in compliance 

with DO 160 environmental standard. 

The short circuiting could result in 

arcing and consequent smoke or fire. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

SICMA Aero Seat has issued Service 

Bulletin No. 50–25–210, dated June 27, 

2005. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 


cprice-sewell on PROD1PC66 with PROPOSALS
20964 Federal Register / Vol. 72, No. 81 / Friday April 27, 2007 / Proposed Rules 

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 reference 

above. We are proposing 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. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the proposed AD is clear for 

U.S. operators and is enforceable. In 

making these changes, we do not intend 

to differ substantively from the 

information provided in the MCAI and 

related service information. 

We might also have proposed 

different actions in this proposed AD 

from those in the MCAI in order to 

follow FAA policies. Any such 

differences are described in a separate 

paragraph of the proposed AD. These 

requirements, if ultimately adopted, will 

take precedence over the actions copied 

from the MCAI. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 16,108 seats on airplanes of 

U.S. registry. We also estimate that it 

would take about .33 work-hours per 

product to comply with this proposed 

AD. The average labor rate is $80 per 

work-hour. Required parts would cost 

about $3,475 per seat. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$56,400,551, or $3,501 per seat. 

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); and 

3. 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 proposed AD and placed it in the 

AD docket.

Reason 

(d) Direction General De L’ Aviation Civile 

(DGAC) Airworthiness Directive F–2005–135, 

dated August 3, 2005, states: 

A release of smoke was experienced in the 

passenger compartment during flight after an 

overheating of a reading lights power box of 

a PN 5039201–4T SICMA seat. An analysis 

put into evidence that this overheating was 

caused by short-circuit produced by the 

rupture of an electrical power supply 

component (PN 78147–B). It has been noticed 

that this power supply is not in compliance 

with DO 160 environmental standard. 

The short circuiting could result in arcing 

and consequent smoke or fire. 

Actions and Compliance 

(e) Unless already done, within six months 

from the effective date of this AD, identify 

the seats part numbers listed in the Table 1 

of this AD and replace installed reading
