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: 

During an elevator Power Control Unit 

(PCU) Centering Functional Check on two 

CL–600–2C10 aircraft, sustained oscillations 

were discovered when a control rod was 

disconnected. These sustained oscillations 

could render the elevator surface inoperable 

and cause subsequent loss of pitch control of 

the aircraft. 

* * * * * 

Loss of pitch control could result in 

reduced controllability of the airplane. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

3, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of June 3, 2010.

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 3, 2009 (74 FR 

63331). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

During an elevator Power Control Unit 

(PCU) Centering Functional Check on two 

CL–600–2C10 aircraft, sustained oscillations 

were discovered when a control rod was 

disconnected. These sustained oscillations 

could render the elevator surface inoperable 

and cause subsequent loss of pitch control of 

the aircraft. 

This directive mandates incorporation of a 

new centering mechanism on the elevator 

torque tube to prevent these sustained 

oscillations. 

Loss of pitch control could result in 

reduced controllability of the airplane. 

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 

considered the comment received. 

Request To Include Revised Service 

Information 

Comair, Inc., asks that we allow the 

use of Revision C instead of Revision B 

of Bombardier Service Bulletin 670BA– 

27–042 for accomplishing the actions 

specified in paragraph (f)(1) of the 

NPRM. Comair, Inc., states that 

Bombardier has issued Bombardier 

Service Bulletin 670BA–27–042, 

Revision C, dated December 10, 2009. 

We referred to Bombardier Service 

Bulletin 670BA–27–042, Revision B, 

dated June 2, 2009, in paragraph (f)(1) 

of the NPRM as the appropriate source 

of service information for accomplishing 

the specified actions. 

We agree with the commenter. 

Bombardier Service Bulletin 670BA–27– 

042, Revision C, dated December 10, 

2009, makes minor updates and 

editorial changes; no additional work is 

necessary on airplanes modified in 

accordance with Revision B. Therefore, 

we have revised paragraph (f)(1) of this 

final rule to refer to Bombardier Service 

Bulletin 670BA–27–042, Revision C, 

dated December 10, 2009, for 

accomplishing the specified actions. We 

have also revised paragraph (f)(2) of this 

AD to give credit for actions done in 

accordance with Bombardier Service 

Bulletin 670BA–27–042, Revision B, 

dated June 2, 2009. 

mstockstill on DSKH9S0YB1PROD with RULES

Federal Register / Vol. 75, No. 82 / Thursday, April 29, 2010 / Rules and Regulations 22507 

Explanation of Change Made to This 

AD 

We have changed this AD to identify 

the correct 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 comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

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 

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 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 

260 products of U.S. registry. We also 

estimate that it will take about 35 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $27,626 

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 

this AD to the U.S. operators to be 

$7,956,260, or $30,601 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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

specified Eurocopter France 

(Eurocopter) model helicopters. This AD 

results from a mandatory continuing 

airworthiness information (MCAI) AD 

issued by the European Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community. The MCAI AD 

was issued following the discovery of a 

potential risk of an untimely squib firing 

that would cut the hoist cable. A short 

circuit in the hoist motor brush power 

supply wiring resulting in an 

uncommanded squib firing, which cuts 

the hoist cable, constitutes an unsafe 

condition. 

DATES: This AD becomes effective on 

May 14, 2010. 

The incorporation by reference of 

Eurocopter Alert Service Bulletin No. 

25.00.85 and No. 25.00.95, both dated 

November 16, 2005, is approved by the 

Director of the Federal Register as of 

May 14, 2010.
