Airworthiness Directives; Saab AB, 

Saab Aerosystems Model SAAB 2000 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective April 

14, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 14, 2011.

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 14, 2010 (75 FR 

77796). That NPRM proposed 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. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

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 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 8 

products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the 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 


jdjones on DSK8KYBLC1PROD with RULES
Federal Register / Vol. 76, No. 47 / Thursday, March 10, 2011 / Rules and Regulations 13073 

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 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); 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 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, 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

section. Comments will be available in 

the AD docket shortly after receipt. 

List of Subjects in 14 CFR Part 39

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–05–13 Saab AB, Saab Aerosystems: 

Amendment 39–16623. Docket No. 

FAA–2010–1198; Directorate Identifier 

2010–NM–145–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 14, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Saab AB, Saab 

Aerosystems Model SAAB 2000 airplanes,

Reason 

(e) The mandatory continuing 

airworthiness information (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.
