Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This proposed AD was 

prompted by reports of fractured rudder 

pedal tubes installed on the pilot-side 

rudder bar assembly. This proposed AD 

would require repetitive inspections for 

cracking and damage of both pilot-side 

rudder pedal tubes, and replacement of 

affected pilot-side rudder bar assemblies 

if necessary. We are proposing this AD 

to detect and correct cracking of both 

pilot-side rudder pedal tubes, which 

could result in loss of pilot rudder pedal 

input causing reduced yaw 

controllability or a runway excursion. 

DATES: We must receive comments on 

this proposed AD by October 10, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2013–12, 

dated May 14, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

There have been two in-service reports of 

fracture of rudder pedal tubes installed on 

the pilot-side rudder bar assembly. 

Laboratory examination of the fractured 

rudder pedal tubes found that in both cases, 

the fatigue cracks initiated at the aft taper pin 

holes where the connecting rod fitting is 

attached. Fatigue testing of the rudder pedal 

tubes confirmed that the fatigue cracking is 

due to loads induced during parking brake 

application. Therefore, only the rudder pedal 

tubes on the pilot’s side are vulnerable to 

fatigue cracking as the parking brake is 

primarily applied by the pilot. 

Loss of pilot rudder pedal input during 

flight would result in reduced yaw 

controllability of the aeroplane. Loss of pilot 

rudder pedal input during takeoff or landing 

may lead to a runway excursion. 

This [Canadian] AD mandates initial and 

repetitive [detailed or eddy current] 

inspections [for cracking and damage and 

replacement if necessary] of the pilot-side 

rudder * * * [bar assembly], until the 

terminating action is accomplished. 

Required actions also include repairing 

damage. The terminating action is 

replacement of both pilot-side rudder 

bar assemblies. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 601R–27–162, including 

Appendix A, dated April 5, 2013. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 


ehiers on DSK2VPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 78, No. 165 / Monday, August 26, 2013 / Proposed Rules 52713 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Clarification of Inspection Terminology 

In this proposed AD, the ‘‘detailed 

visual inspection’’ specified in 

Bombardier Service Bulletin 601R–27– 

162, including Appendix A, dated April 

5, 2013, is referred to as a ‘‘detailed 

inspection.’’ We have included the 

definition for a detailed inspection in 

paragraph (h) of the proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 529 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Inspection ............................................................... 3 work-hours × $85 per 

hour = $255 per inspection cycle.

$0 $255 per inspection 

cycle.

$134,895 per inspection cycle. 

We estimate the following costs to do 

any necessary replacement that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of aircraft that 

might need this repair: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 6 work-hours × $85 per hour = $510 ........................... $2,850 $3,360 

We have received no definitive data 

that would enable us to provide a cost 

estimate for the repair specified in this 

proposed AD. 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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 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 this 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); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. 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.
