Airworthiness Directives; Bombardier 

Model CL–600–2B16 (CL–604) Series 

Airplanes

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Bombardier Model CL–600–

2B16 (CL–604) series airplanes. This 

proposed AD would require replacing 

the side-brace fitting shafts of the main 

landing gear (MLG) with new, improved 

side-brace fitting shafts; inspecting for 

corrosion of the MLG side-brace fitting 

shafts; and replacing the nut, washer, 

and cotter pin of the MLG side-brace 

fitting shafts with new parts; as 

applicable. This proposed AD is 

prompted by the discovery of fractures 

of the MLG side-brace fitting shafts 

caused by corrosion on the forward side 

of the side-brace fitting shafts. We are 

proposing this AD to prevent fracture of 

the MLG side-brace fitting shafts, which 

could result in collapse of the MLG.

DATES: We must receive comments on 

this proposed AD by December 9, 2004.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, notified the FAA 

that an unsafe condition may exist on 

certain Bombardier Model CL–600–

2B16 (CL–604) series airplanes. TCAA 

advises that there have been reports of 

fractures of the side-brace fitting shafts 

of the main landing gear (MLG). 

Investigation revealed that the fractures 

were caused by corrosion on the 

forward side of the MLG side-brace 

fitting shafts. Fractures of the side-brace 

64870 Federal Register / Vol. 69, No. 216 / Tuesday, November 9, 2004 / Proposed Rules 

fitting shafts, if not corrected, could 

result in collapse of the MLG. 

Relevant Service Information 

Bombardier has issued Alert Service 

Bulletin (ASB) A604–32–018, Revision 

01, dated February 22, 2002. The 

procedures in that ASB are divided into 

Parts A, B, and C, each of which applies 

to different groups of airplanes. Part A 

of the ASB describes procedures for 

replacing the side-brace fitting shafts of 

the left-hand (LH) and right-hand (RH) 

MLG with new, improved side-brace 

fitting shafts; and replacing the nut, 

washer, and cotter pin of the MLG sidebrace fitting shafts with new parts. Part 

B of the ASB describes procedures for 

inspecting for corrosion of the LH and 

RH MLG side-brace fitting shafts, 

replacing the shafts with new, improved 

shafts if corrosion is found, and 

replacing the nut, washer, and cotter pin 

of the MLG side-brace fitting shafts with 

new parts. Part C of the ASB describes 

procedures for replacing, with new 

parts, the nut and washer on the 

forward side of each MLG side-brace 

fitting shaft. Accomplishing the 

applicable actions specified in the ASB 

is intended to adequately address the 

unsafe condition. TCCA mandated the 

ASB and issued Canadian airworthiness 

directive CF–2002–43, dated September 

30, 2002, to ensure the continued 

airworthiness of these airplanes in 

Canada. 

FAA’s Determination and Requirements 

of the Proposed AD 

This airplane model is manufactured 

in Canada and is 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 AD action is necessary 

for products of this type design that are 

certificated for operation in the United 

States. Therefore, we are proposing this 

AD, which would require 

accomplishing the applicable actions 

specified in the service information 

described previously, except as 

discussed under ‘‘Difference Among the 

Proposed AD, ASB, and Canadian 

Airworthiness Directive.’’

Clarification of Inspection Terminology 

In this proposed AD, we refer to the 

inspection for corrosion that is specified 

in the ASB as a ‘‘general visual 

inspection.’’ We have included the 

definition for this type of inspection in 

a note in the proposed AD. 

Difference Among the Proposed AD, 

ASB, and Canadian Airworthiness 

Directive 

Both the ASB and Canadian 

Airworthiness Directive specify 

reporting certain information and 

returning removed parts to Bombardier. 

This proposed AD would not require 

these actions. 

Costs of Compliance 

This proposed AD would affect about 

163 airplanes of U.S. registry. The 

proposed actions would take up to 16 

work hours per airplane, at an average 

labor rate of $65 per work hour. Based 

on these figures, the estimated cost of 

the proposed AD for U.S. operators is up 

to $169,520, or up to $1,040 per 

airplane. 

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. See the ADDRESSES

section for a location to examine the 

regulatory evaluation.

Airworthiness Directives; Airbus Model 

A310 Series Airplanes

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Model A310 series airplanes. 

This proposed AD would require 

modifying the wire routing of electrical 

harness 636VB in the right-hand wing. 

This proposed AD is prompted by the 

manufacturer’s analysis for compliance 

with Special Federal Aviation 

Regulation No. 88, which has shown 

that wiring 2M of the 115V anticollision white strobe lights and wiring 

2S of the fuel quantity indication system 

(FQIS) should be rerouted into separate 

conduits. We are proposing this AD to 

prevent chafing damage to wiring 2M 

and 2S, which could result in a short 

circuit and consequently introduce an 

electrical current into the wiring of the 

FQIS and create an ignition source in 

the fuel tank.

DATES: We must receive comments on 

this proposed AD by December 9, 2004.

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.
