RIN 3150–AI06 

Geologic Repository Operations Area 

Security and Material Control and 

Accounting Requirements 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Availability of preliminary draft 

rule language. 

SUMMARY: The Nuclear Regulatory 

Commission (NRC) is making available 

preliminary draft rule language to 

amend its regulations to revise the 

security requirements and material 

control and accounting (MC&A) 

requirements for a geologic repository 

operations area (GROA). The goal of this 

rulemaking is to ensure effective 

security measures are in place for the 

protection of high-level radioactive 

waste given the post-September 11, 

2001, threat environment. New 

requirements for specific training 

enhancements, improved access 

authorization, and enhancements to 

defensive strategies will be 

incorporated. The proposed rule will 

reinstate the alcohol and drug 

provisions of the fitness-for-duty 

provisions to a GROA. The proposed 

rule will also impose the fatigue portion 

of the fitness-for-duty requirements for 

the security personnel at a GROA. The 

proposed rule will establish general 

performance objectives and 

corresponding system capabilities for 

the GROA MC&A program, with a focus 

on strengthening, streamlining, and 

consolidating all MC&A regulations 

specific to a GROA. In addition, the 

proposed rule will require the 

emergency plan to address radiological 

emergencies. The availability of the 

preliminary draft rule language is 

intended to inform stakeholders of the 

current status of the NRC’s activities, 

but the NRC is not soliciting formal 

public comments on the information at 

this time. 

DATES: There will be an opportunity for 

public comment when the notice of 

proposed rulemaking is published in the 

Federal Register. 

ADDRESSES: The preliminary draft rule 

language can be viewed and 

downloaded electronically via the 

NRC’s rulemaking Web site at http:// 

ruleforum.llnl.gov. Along with any 

publicly available documents related to 

this rulemaking, the draft information 

may be viewed electronically on public 

computers in the NRC’s Public 

Document Room (PDR), located at One 

White Flint North, 11555 Rockville 

Pike, Rockville, Maryland 20852, Room 

O–1 F21, and open to the public on 

Federal workdays from 7:45 a.m. until 

4:15 p.m. The PDR reproduction 

contractor will make copies of 

documents for a fee.

SUPPLEMENTARY INFORMATION: The NRC 

is making a preliminary version of the 

draft proposed rule language available 

to inform stakeholders of the current 

status of this proposed rulemaking. This 

preliminary draft rule language may be 

subject to significant revisions during 

the rulemaking process. The NRC is not 

soliciting early public comments on this 

preliminary draft rule language. No 

stakeholder requests for a comment 

period will be granted at this stage in 

the rulemaking process. Stakeholders 

will have an opportunity to comment on 

the rule language when it is published 

as a proposed rule. 

The NRC’s preliminary draft rule 

language will be posted on the NRC’s 

rulemaking Web site at http:// 

ruleforum.llnl.gov. The NRC may post 

updates to the draft proposed rule 

language on the rulemaking Web site.

Airworthiness Directives; Cirrus 

Design Corporation Models SR20 and 

SR22 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Cirrus Design Corporation (CDC) Models 

SR20 and SR22 airplanes. This 

proposed AD would require you to 

replace the pick-up collar support and 

nylon screws, of the Cirrus Airplane 

Parachute System (CAPS), with a new 

design pick-up collar support and 

custom tension screws. This proposed 

AD results from a CDC report of an inflight CAPS activation where the 

parachute failed to successfully deploy. 

We are proposing this AD to correct 

pick-up collar support fasteners of the 

CAPS, which could result in the 

premature separation of the collar. This 

condition, if not corrected, could result 

in the parachute failing to successfully 

deploy (CAPS failure). 

DATES: We must receive comments on 

this proposed AD by June 18, 2007. 

ADDRESSES: Use one of the following 

addresses to comment on this proposed 

AD:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments 

regarding this proposed AD. Send your 

comments to an address listed under the 

ADDRESSES section. Include the docket 

number, ‘‘FAA–2007–27976; Directorate 

Identifier 2007–CE–042–AD’’ at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

the proposed AD. We will consider all 

comments received by the closing date 

and may amend the proposed AD in 

light of 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 

concerning this proposed AD. 

Discussion 

We have received a CDC report of an 

in-flight CAPS activation where the 

parachute failed to successfully deploy. 

A CDC airplane in Australia had an 

engine failure and was making an off 

airport landing. The pilot activated the 

CAPS, and evidence indicates that the 

parachute was not properly extracted 

from the airplane. 

Testing indicates that the force of the 

CAPS rocket ignition and rocket blase 

may prematurely break the nylon pick 

up collar/support screws. When 

functioning properly the screws should 

not break until impacted by a flange at 

the rocket base. A prematurely 

separated collar/support may bind on 

the rocket as it slides down toward the 

flange at the base of the rocket. This 

may alter the direction of the rocket. 

This condition, if not corrected, could 

result in the parachute failing to 

successfully deploy (CAPS failure). 

Relevant Service Information 

We have reviewed CDC’s Alert 

Service Bulletin No. SB A2X–95–10 R2, 

Issued April 2, 2007, Revised: April 24, 

2007. 

The service information describes 

procedures for replacing the pick-up 

collar support of the CAPS with a new 

design pick-up collar support and 

replacing the nylon screws with custom 

aluminum tension screws. 

FAA’s Determination and Requirements 

of the Proposed AD 

We are proposing this AD because we 

evaluated all information and 

determined the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. This proposed AD would 

require you to do a replacement of the 

pick-up collar support and associated 

fastening screws of the CAPS. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 2,677 airplanes in the U.S. 

registry. 

We estimate the following costs to do 

the proposed replacement of the pick-up 

collar support of the CAPS: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on 

U.S. operators 

2 work-hours × $80 per hour = $160 .................................................................................... $17 $177 $473,829 

Note: CDC will provide warranty credit to 

the extent noted in Cirrus Alert Service 

Bulletin No. SB A2X–95–10 R2, Issued April 

2, 2007, Revised: April 24, 2007. 

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 have 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 that the 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 porposed AD and placed it in the 

AD docket. 

Examining the AD Docket 

You may examine the AD docket that 

contains the proposed AD, the 

regulatory evaluation, any comments 

received, and other information on the 

Internet at http://dms.dot.gov; or in 

person at the Docket Management 

Facility between 9 a.m. and 5 p.m., 

Monday through Friday, except Federal 

holidays. The Docket Office (telephone 

(800) 647–5227) is located at the street 

address stated in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.

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) 

originated 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 nose landing gear leg failed in area of the 

nose gear leg pivot axle. This airplane was 

mostly operated on grass runways and 

training operations. This failure was based on 

a fatigue crack developed in the pivot axle. 

Material inspections figured out that this 

cracks may also develop on other serial No. 

pending the type of operation. 

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 June 18, 2007. 

ADDRESSES: You may send comments by 

any of the following methods:
