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) 

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: 

Corrosion has been found on the rear spar 

upper cap of the horizontal stabilizer of 

SAAB 2000 aeroplanes. The affected areas 

are adjacent to the inboard elevator hinge 

where the electrical wiring harnesses are 

located and wired through the lightening 

holes. The upper spar cap is a primary 

structural element and is important to the 

structural integrity of the horizontal 

stabilizer. 

Corrosion damage in these areas, if not 

detected and corrected, can result in a 

starting point for future crack propagation, 

which would impair the integrity of the 

horizontal stabilizer upper spar cap structure. 

* * * * * 

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 January 28, 2011.

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 2010–0115, 

dated June 17, 2010 (referred to after 

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

condition for the specified products. 

The MCAI states: 

Corrosion has been found on the rear spar 

upper cap of the horizontal stabilizer of 

SAAB 2000 aeroplanes. The affected areas 

are adjacent to the inboard elevator hinge 

where the electrical wiring harnesses are 

located and wired through the lightening 

holes. The upper spar cap is a primary 

structural element and is important to the 

structural integrity of the horizontal 

stabilizer. 

Corrosion damage in these areas, if not 

detected and corrected, can result in a 

starting point for future crack propagation, 

which would impair the integrity of the 

horizontal stabilizer upper spar cap structure. 

For the reasons describe above, this AD 

requires a detailed visual inspection (DVI) of 

the LH and RH horizontal stabilizer rear spar 

adjacent to the inboard elevator hinge and 

the harnesses installed in the adjacent areas, 

installation of convoluted tubing on the 

harness, and corrective actions depending on 

findings. 

The corrective actions include installing 

convoluted tubing on the harness, 

applying corrosion prevention 

compound to the inspected area, making 

sure clearance exists between the spar 

cap and the harnesses/convoluted tube, 

and contacting Saab for repair 

instructions and doing the repair. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Saab AB, Saab Aerosystems has 

issued Service Bulletin 2000–55–013, 

dated July 6, 2009. 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 

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 AD is clear for U.S. 

operators and is enforceable. In making 

WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS

Federal Register / Vol. 75, No. 239 / Tuesday, December 14, 2010 / Proposed Rules 77797 

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 AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 8 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$1,360, or $170 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); 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.

3356; telephone (425) 227–1112; fax (425) 

227–1149. Before using any approved AMOC 

on any airplane to which the AMOC applies, 

notify your principal maintenance inspector 

(PMI) or principal avionics inspector (PAI), 

as appropriate, or lacking a principal 

inspector, your local Flight Standards District 

Office. The AMOC approval letter must 

specifically reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: A Federal 

agency may not conduct or sponsor, and a 

person is not required to respond to, nor 

shall a person be subject to a penalty for 

failure to comply with a collection of 

information subject to the requirements of 

the Paperwork Reduction Act unless that 

collection of information displays a current 

valid OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public reporting for 

this collection of information is estimated to 

be approximately 5 minutes per response, 

including the time for reviewing instructions,

SUPPLEMENTARY INFORMATION: 

Extension of the Comment Period 

On October 19, 2010, OSHA 

published a notice of proposed 

interpretation entitled Interpretation of 

OSHA’s Provisions for Feasible 

Administrative or Engineering Controls 

of Occupational Noise. The notice 

proposed to clarify that the term feasible 

administrative or engineering controls 

as used in the applicable sections of 

OSHA’s General Industry and 

Construction Occupational Noise 

Exposure standards has its ordinary 

meaning of capable of being done. The 

Agency announced its intention to 

revise and clarify its current 

enforcement policy to reflect this 

interpretation, and solicited comments 

from interested parties within 60 days, 

ending on December 20, 2010. 

OSHA’s current enforcement policy 

for exposures less than 100 dBA has not 

reflected the noise standard’s 

requirement that feasible engineering 

and administrative controls be used as 

the primary means of reducing noise 

exposure. Instead, the Agency has 

allowed many employers to rely upon a 

hearing conservation program, 

including the use of hearing protectors. 

Excessive noise levels continue to be 

a cause of hearing loss in the nation’s 

workplaces. Since 2004, the Bureau of 

Labor Statistics (BLS) has reported that 

over 125,000 workers have suffered 

significant, permanent hearing loss. In 

2008 alone, BLS reported 22,000 hearing 

loss cases. 

Two commenters, the National 

Association of Manufacturers and the 

Coalition for Workplace Safety (CWS), 

representing employers who would be 

affected by the proposed interpretation, 

have requested an extension of 90 days 

to assess the operating changes that 

their members would be required to 

make to comply with the interpretation. 

In addition, CWS cites the proximity of 

the current deadline to the winter 

holidays as an additional reason for the 

extension. 

OSHA believes that these requests are 

reasonable. OSHA is interested in 

hearing from and carefully considering 

the views of affected persons before 

making a final decision on the proposed 

interpretation. Accordingly, to facilitate 

the submission of more thorough 

comments and help the agency assess 

the issues, OSHA is extending the 

comment period by 90 days from 

December 20, 2010 to March 21, 2011.
