AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt 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, & CL–604) airplanes. This 

proposed AD would require modifying 

the rudder balance spring assembly by 

installing a new adjustable balance 

spring, and rigging the assembly to suit 

the rudder of each airplane. This 

proposed AD results from production 

inspections that showed that the spring 

assembly that controls rudder balance 

may not have the correct pre-load on 

some airplanes. We are proposing this 

AD to prevent uncommanded yaw 

movements and consequent reduced 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by December 12, 

2005.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, notified us that an 

unsafe condition may exist on certain 

Bombardier Model CL–600–1A11 (CL–

600), CL–600–2A12 (CL–601), and CL–

600–2B16 (CL–601–3A, CL–601–3R, & 

CL–604) airplanes. TCCA advises that 

production inspections showed that the 

spring assembly that controls rudder 

balance may not have the correct preload on some airplanes. The spring 

assembly must be pre-loaded correctly 

so it can position the rudder close to its 

neutral position in case one of several 

linked components in the aft section of 

the rudder assembly disconnects during 

flight. If the rudder is not positioned 

close to neutral in this instance, 

excessive rudder deflections (side-toside movements) may occur. In order to 

ensure that the rudder moves to neutral 

position and rudder deflections remain 

within acceptable limits, the balance 

spring assembly must be modified and 

rigged to suit the rudder of each 

airplane. No linked components in the 

aft section of the rudder assembly have 

disconnected in service; however, this 

condition, if not corrected, could result 

in uncommanded yaw movement and 

reduced controllability of the airplane. 

Relevant Service Information 

Bombardier has issued the service 

bulletins in the following table. 

SERVICE BULLETINS

Bombardier service bulletin— For Bombardier airplane model(s)—

600–0714, including Appendixes 1 and 2, dated April 4, 2003 ............... CL–600–1A11 (CL–600). 

601–0549, including Appendixes 1 and 2, dated April 4, 2003 ............... CL–600–2A12 (CL–601) and CL–600–2B16 (CL–601–3A and CL–601–

3R). 

604–27–013, including Appendixes 1 and 2, dated April 4, 2003 ........... CL–600–2B16 (CL–604). 

68378 Federal Register / Vol. 70, No. 217 / Thursday, November 10, 2005 / Proposed Rules 

The service bulletins describe 

procedures for modifying the rudder 

balance spring assembly by installing a 

new adjustable balance spring; and 

rigging the adjustable rudder balance 

spring assembly by measuring, 

adjusting, and testing the deflection to 

be within the limits specified in the 

applicable service bulletin. If the 

deflection cannot be adjusted to be 

within acceptable limits defined in the 

service bulletins, the service bulletins 

specify that operators contact the 

manufacturer for further instructions. 

Accomplishing the actions specified 

in the service information is intended to 

adequately address the unsafe 

condition. TCCA mandated the service 

information and issued Canadian 

airworthiness directive CF–2005–21, 

dated June 23, 2005, to ensure the 

continued airworthiness of these 

airplanes in Canada. 

FAA’s Determination and Requirements 

of the Proposed AD 

These airplane models are 

manufactured in Canada and are type 

certificated for operation in the United 

States under the provisions of section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Pursuant to this bilateral 

airworthiness agreement, TCCA has 

kept the FAA informed of the situation 

described above. We have examined 

TCCA’s findings, evaluated all pertinent 

information, and determined that we 

need to issue an AD for airplanes of this 

type design that are certificated for 

operation in the United States. 

Therefore, we are proposing this AD, 

which would require accomplishing the 

actions specified in the service 

information described previously, 

except as discussed under ‘‘Difference 

Between Proposed AD, Service Bulletin 

604–27–013, and Canadian 

Airworthiness Directive.’’

Difference Between Proposed AD and 

Service Bulletins 

The service bulletins specify that you 

contact the manufacturer for 

instructions on how to make certain 

adjustments, but this proposed AD 

would require you to make the 

adjustments using a method that we or 

TCCA approve. 

Difference Among Proposed AD, 

Service Bulletin 604–27–013, and 

Canadian Airworthiness Directive 

Although the Canadian airworthiness 

directive and Bombardier Service 

Bulletin 604–27–013 indicate that the 

actions proposed in this AD would 

apply to Model CL–600–2B16 (CL–604) 

airplanes, serial numbers (S/Ns) 5301 

through 5584, this proposed AD would 

apply to S/Ns 5301 through 5564. 

Service Bulletin Information Sheet 604–

27–013, dated January 30, 2004, 

indicates that Model CL–600–2B16 (CL–

604) airplanes, S/Ns 5565 and 

subsequent, are scheduled to have this 

modification in production. Therefore, 

this proposed AD would not apply to 

Model CL–600–2B16 (CL–604) 

airplanes, S/Ns 5565 and subsequent. 

The manufacturer is aware of this 

discrepancy, and concurs with the 

change. This difference has also been 

coordinated with TCCA. 

Costs of Compliance 

This proposed AD would affect about 

501 airplanes of U.S. registry. The 

proposed actions would take about 12 

work hours per airplane, at an average 

labor rate of $65 per work hour. 

Required parts would cost about $1,749 

per airplane. Based on these figures, the 

estimated cost of the proposed AD for 

U.S. operators is $1,267,029, or $2,529 

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 

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 that the 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. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation.

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus Model A319–100 and 

A320–200 series airplanes. This 

proposed AD would require repetitive 

inspections of the wing-tank fuel 

pumps, canisters, and wing fuel tanks 

for detached identification labels, and 

corrective action if necessary. This 

proposed AD results from several 

incidents of detached plastic 

identification labels found floating in 

the wing fuel tanks. We are proposing 

this AD to prevent plastic identification 

labels being ingested into the fuel 

pumps and consequently entering the 

engine fuel feed system, which could 

result in an engine shutdown. 

DATES: We must receive comments on 

this proposed AD by December 12, 

2005. 

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.
