AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Bombardier Model CL–600–1A11 (CL–

600), CL–600–2A12 (CL–601), and CL–

600–2B16 (CL–601–3A, CL–601–3R, and 

CL–604) airplanes. This AD requires 

inspecting to identify the part number 

and serial number of the selector valves 

of the nose landing gear (NLG) and the 

nose gear door, and doing related 

investigative and corrective actions if 

necessary. This AD results from reports 

of uncommanded partial retractions of 

the NLG. We are issuing this AD to 

prevent internal leakage of the selector 

valve, which, under certain conditions, 

could result in an uncommanded 

retraction of the NLG with consequent 

damage to the airplane and possible 

serious injury to ground personnel. 

DATES: This AD becomes effective 

August 16, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of August 16, 2007.

SUPPLEMENTARY INFORMATION: 

Examining the Docket 

You may examine the AD docket on 

the Internet at http://dms.dot.gov or in 

person at the Docket Operations office 

between 9 a.m. and 5 p.m., Monday 

through Friday, except Federal holidays.

ground floor of the West Building at the 

street address stated in the ADDRESSES

section. 

Discussion 

The FAA issued a supplemental 

notice of proposed rulemaking (NPRM) 

to amend 14 CFR part 39 to include an 

AD that would apply to certain 

Bombardier Model CL–600–1A11 (CL–

600), CL–600–2A12 (CL–601), and CL–

600–2B16 (CL–601–3A, CL–601–3R, and 

CL–604) airplanes. That supplemental 

NPRM was published in the Federal 

Register on April 26, 2007 (72 FR 

20777). That supplemental NPRM 

proposed to require inspecting to 

identify the part number and serial 

number of the selector valves of the 

nose landing gear (NLG) and the nose 

gear door, and doing related 

investigative and corrective actions if 

necessary. That supplemental NPRM 

also proposed to add airplanes to the 

applicability. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the supplemental 

NPRM or on the determination of the 

cost to the public. 

Clarification of Alternative Method of 

Compliance (AMOC) Paragraph 

We have revised this action to clarify 

the appropriate procedure for notifying 

the principal inspector before using any 

approved AMOC on any airplane to 

which the AMOC applies. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD with the change 

described previously. We have 

determined that this change will neither 

increase the economic burden on any 


cprice-sewell on PROD1PC71 with RULES
Federal Register / Vol. 72, No. 133 / Thursday, July 12, 2007 / Rules and Regulations 38005 

operator nor increase the scope of the 

AD. 

Costs of Compliance 

This AD affects about 502 airplanes of 

U.S. registry. 

The inspection to determine the 

manufacturer part number and serial 

number of the selector valve(s) takes 

about 1 work hour per airplane, at an 

average labor rate of $80 per work hour. 

Based on these figures, the estimated 

cost of the required inspection for U.S. 

operators is $40,160, or $80 per 

airplane. 

The general visual inspection of the 

selector valve(s), if accomplished, takes 

about 1 work hour per airplane, at an 

average labor rate of $80 per work hour. 

Based on these figures, the estimated 

cost of that inspection for U.S. operators 

is $80 per airplane. 

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 have 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

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. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus Model A330 and A340 airplanes. 

This AD requires revising the 

Airworthiness Limitations Section of 

the Instructions for Continued 

Airworthiness to incorporate new 

limitations for fuel tank systems. This 

AD results from fuel system reviews 

conducted by the manufacturer. We are 

issuing this AD to prevent the potential 

of ignition sources inside fuel tanks, 

which, in combination with flammable 

fuel vapors caused by latent failures, 

alterations, repairs, or maintenance 

actions, could result in fuel tank 

explosions and consequent loss of the 

airplane. 

DATES: This AD becomes effective 

August 16, 2007. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the AD as of

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to all Airbus Model A330 and 

A340 airplanes. That NPRM was 

published in the Federal Register on 

April 5, 2007 (72 FR 16741). That NPRM 

proposed to require revising the 

Airworthiness Limitations section of the 

Instructions for Continued 

Airworthiness to incorporate new 

limitations for fuel tank systems. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Changes to This AD 

We have removed Model A330–302, 

A330–303, and A340–643 airplanes 

from the applicability of this AD, since 

we have not yet certificated those 

airplane models for operation in the
