SIGAR. To promote effective law 

enforcement, SIGAR will have to 

disclose such violations to other law 

enforcement agencies, including State, 

local and foreign agencies that have 

jurisdiction over the offenses to which 

the information relates. Otherwise, 

SIGAR might be placed in the position 

of having to ignore information relating 

to violations of law not within the 

jurisdiction of SIGAR when that 

information comes to SIGAR’s attention 

during the collation and analysis of 

information in its records. 

(5) 5 U.S.C. 552a (e)(4)(G) and (f)(1) 

enable individuals to inquire whether a 

system of records contains records 

pertaining to them. Application of these 

provisions to the systems of records 

would allow individuals to learn 

whether they have been identified as 

suspects or subjects of investigation. As 

further described in the following 

paragraph, access to such knowledge 

would impair SIGAR’s ability to carry 

out its mission, since individuals could: 

(i) Take steps to avoid detection; 

(ii) Inform associates that an 

investigation is in progress; 

(iii) Learn the nature of the 

investigation; 

(iv) Learn whether they are only 

suspects or identified as law violators; 

(v) Begin, continue, or resume illegal 

conduct upon learning that they are not 

identified in the system of records; or 

(vi) Destroy evidence needed to prove 

the violation. 

(6) 5 U.S.C. 552a(e)(4)(I) requires an 

agency to publish a general notice 

listing the categories of sources for 

information contained in a system of 

records. The application of this 

provision to the systems of records 

could compromise SIGAR’s ability to 

complete or continue investigations or 

to provide useful information to law 

enforcement agencies, since revealing 

sources for the information could: 

(i) Disclose investigative techniques 

and procedures; 

(ii) Result in threats or reprisals 

against informers by the subjects of 

investigations; and 

(iii) Cause informers to refuse to give 

full information to investigators for fear 

of having their identities as sources 

disclosed.

Airworthiness Directives; Saab AB,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Saab AB, Saab Aerosystems Model 340A 

(SAAB/SF340A) and SAAB 340B 

airplanes. This proposed AD was 

prompted by reports of stall events 

during icing conditions which were not 

accompanied with a prior stall warning. 

This proposed AD would require 

replacing the stall warning computer 

(SWC) with a new SWC, and modifying 

the airplane for the replacement of the 

SWC. We are proposing this AD to 

prevent natural stall events when 

operating in icing conditions, which if 

not corrected may result in loss of 

control of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 13, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2011–0219, 

dated November 11, 2011 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

A few natural stall events, specifically 

when operating in icing conditions, have 

been experienced on SAAB 340 series 

aeroplanes, without receiving a prior stall 

warning. This condition, if not corrected, 

could result in loss of control of the 

aeroplane. 

To address this potential unsafe condition, 

a modified stall warning system, 

incorporating improved stall warning logic, 

has been developed. 


emcdonald on DSK67QTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 124 / Wednesday, June 27, 2012 / Proposed Rules 38225 

SAAB have issued Service Bulletin (SB) 

340–27–098 and SB 340–27–099, which 

include instructions to replace the present 

Stall Warning Computer (SWC) with a new 

SWC, and instructions to activate the new 

SWC. The new system includes stall warning 

curves optimized for operation in icing 

conditions, which are activated by selection 

of Engine Anti-Ice. 

For the reasons described above, this 

[EASA] AD requires the replacement of the 

SWC, by installing new SWC Part Number 

(P/N) 0020AK6 on aeroplanes with basic 

wing tip, and installing a new SWC P/N 

0020AK7 on aeroplanes with extended wing 

tip, as applicable to aeroplane configuration. 

Required actions also include modifying 

the airplane for the replacement of the 

SWC. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Saab has issued the following service 

bulletins: 

• SAAB Service Bulletin 340–27–097, 

Revision 03, dated April 19, 2012. 

• SAAB Service Bulletin 340–27–098, 

Revision 01, dated April 13, 2012. 

• SAAB Service Bulletin 340–27–099, 

Revision 01, dated April 13, 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 This Proposed 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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an 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 

EASA AD 2011–0219, dated 

November 11, 2011, prohibits 

installation of certain part numbers 

following the accomplishment of the 

replacement required by paragraph (g) 

of this AD. This AD prohibits 

installation of those part numbers as of 

the effective date of this AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 162 products of U.S. 

registry. We also estimate that it would 

take about 78 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $33,000 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 the 

proposed AD on U.S. operators to be 

$6,420,060, or $39,630 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 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); 

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 proposed AD and placed it in the 

AD docket.
