AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing 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: 

Following in-flight test deployments on 

CL–600–2B19 aircraft, several Air-Driven 

generators (ADGs) failed to come online. 

Investigation revealed that, as a result of a 

wiring anomaly that had not been detected 

during ADG manufacture, a short circuit was 

possible between certain internal wires and 

their metallic over-braided shields, which 

could result in the ADG not providing power 

when deployed. * * * 

The unsafe condition is failure of the 

ADG, which could lead to loss of several 

functions essential for safe flight. We are 

issuing this AD to require actions to 

correct the unsafe condition on these 

products. 

DATES: This AD becomes effective July 

12, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of April 30, 2009 (74 FR 

13094, March 26, 2009).

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 November 5, 2009 (74 FR 

57268), and proposed to supersede AD 

2009–06–18, Amendment 39–15855 (74 

FR 13094, March 26, 2009). You may 

obtain further information by examining 

the MCAI in the AD docket. 

Since we issued AD 2009–06–18, we 

have received notice that additional 

suspect air-driven generators may have 

been installed between the effective date 

of Canadian Airworthiness Directive 

CF–2008–10, dated February 5, 2008, 

and the effective date of the equivalent 

FAA AD, AD 2009–06–18. Therefore, 

we have determined that the actions 

required by paragraph (f)(1) of AD 2009– 

06–18 are also required for Model CL– 

600–2C10 airplanes having serial 

numbers 10266 through 10273 

inclusive, and Model CL–600–2D15 and 

CL–600–2D24 airplanes having serial 

numbers 15163 through 15223 

inclusive. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Support for the NPRM 

The Air Line Pilots Association, 

International (ALPA) supports the intent 

of the NPRM. 

Request To Allow Previously Approved 

AMOCs 

American Eagle Airlines (American 

Eagle) requests that we allow alternative 

methods of compliance (AMOCs) 

previously approved for AD 2009–06– 

18. American Eagle states that including 

a statement allowing previously 

approved AMOCs will prevent the need 

for duplicate requests for the same 

issue. 

We agree with the commenter’s 

request. We have determined that 

AMOCs previously approved for AD 

2009–06–18 are acceptable for 

compliance with the corresponding 

requirements of this AD. We have added 

a statement to paragraph (h)(1) of this 

AD to allow AMOCs approved 

previously in accordance with AD 

2009–06–18. 

Explanation of Change Made to This 

AD 

We have revised this AD to identify 

the legal name of the manufacturer as 

published in the most recent type 

certificate data sheet for the affected 

airplane models. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes do 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

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 

WReier-Aviles on DSKGBLS3C1PROD with RULES

Federal Register / Vol. 75, No. 108 / Monday, June 7, 2010 / Rules and Regulations 32091 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the original NPRM, 

we have increased the labor rate used in 

the Costs of Compliance from $80 per 

work-hour to $85 per work-hour. The 

Costs of Compliance information, 

below, reflects this increase in the 

specified hourly labor rate. 

Costs of Compliance 

We estimate that this AD will affect 

about 304 products of U.S. registry. The 

actions that are required by AD 2009– 

06–18 and retained in this AD take 

about 5 work-hours per product, at an 

average labor rate of $85 per work hour. 

Required parts cost about $0 per 

product. Based on these figures, we 

estimate the cost of this AD to the U.S. 

operators to be $129,200, or $425 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 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.

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 

removing Amendment 39–15855 (74 FR 

13094, March 26, 2009) and adding the 

following new AD: 

2010–12–05 Bombardier, Inc.: Amendment 

39–16326. Docket No. FAA–2009–1033; 

Directorate Identifier 2009–NM–104–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective July 12, 2010. 

Affected ADs 

(b) This AD supersedes AD 2009–06–18, 

Amendment 39–15855. 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model CL–600–2C10 (Regional Jet Series 700, 

701, & 702) airplanes, having serial numbers 

(S/Ns) 10004 and subsequent; and Model CL– 

600–2D15 (Regional Jet Series 705) airplanes 

and Model CL–600–2D24 (Regional Jet Series 

900) airplanes, having S/N 15002 and 

subsequent; certificated in any category. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 24: Electrical power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Following in-flight test deployments on 

CL–600–2B19 aircraft, several Air-Driven 

generators (ADGs) failed to come online. 

Investigation revealed that, as a result of a 

wiring anomaly that had not been detected 

during ADG manufacture, a short circuit was 

possible between certain internal wires and 

their metallic over-braided shields, which 

could result in the ADG not providing power 

when deployed. This directive mandates 

checking of the ADG and modification of the 

ADG internal wiring, if required. It also 

prohibits future installation of unmodified 

ADGs. 

The unsafe condition is failure of the ADG, 

which could lead to loss of several functions 

essential for safe flight. 

Restatement of Requirements of AD 2009– 

06–18, With No Changes 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) For airplanes identified in Table 1 of 

this AD: Within 12 months after April 30, 

2009 (the effective date of AD 2009–06–18), 

inspect the serial number of the installed 

ADG. A review of airplane maintenance 

records is acceptable in lieu of this 

inspection if the serial number of the ADG 

can be conclusively determined from that 

review.
