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 a determination that 

certain flap actuators require restoration 

by installing a redesigned flap actuator 

inboard pinion seal. This proposed AD 

would require revising the maintenance 

program by incorporating new 

airworthiness limitation tasks. We are 

proposing this AD to prevent flap 

system failure, and consequent reduced 

landing performance of the airplane.

Federal Register / Vol. 78, No. 67 / Monday, April 8, 2013 / Proposed Rules 20845 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2012–26, 

dated October 30, 2012 (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: 

The CL–600–2B19 aeroplane flap actuator 

inboard pinion seal is prone to leak which 

can cause internal contamination of the 

actuator braking mechanism and subsequent 

actuator failure. This condition, if not 

corrected, can cause flap system failure. In 

certain weather and runway conditions, 

frequent flap system failures pose a safety 

concern. 

To improve the internal actuator sealing, 

the flap actuator manufacturer has 

redesigned the inboard pinion seal. Transport 

Canada Civil Aviation (TCCA) has been 

monitoring, through an actuator sampling 

program, the performance of the flap system 

since the introduction of actuators equipped 

with this new inboard pinion seal. Based on 

this sampling program and recent flap 

reliability data, TCCA is mandating a 

restoration task to install the redesigned flap 

actuator inboard pinion seal on all applicable 

actuators. 

The required action is revising the 

maintenance program by incorporating 

two new airworthiness limitation tasks. 

The unsafe condition is flap system 

failure, and consequent reduced control 

of the airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Bombardier Inc. has issued CL–600– 

2B19 Temporary Revision (TR) 2A–48, 

dated July 6, 2012, to Appendix A— 

Certification Requirements, of Part 2, 

Airworthiness Requirements, of the 

Bombardier CL–600–2B19 Maintenance 

Requirements Manual. 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 

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. 

This AD requires revisions to certain 

operator maintenance documents to 

include new actions. Compliance with 

these actions is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by these actions, 

the operator may not be able to 

accomplish the inspections described in 

the revisions. In this situation, to 

comply with 14 CFR 91.403(c), the 

operator must request approval for an 

alternative method of compliance 

according to the procedures specified in 

paragraph (k) of this AD. The request 

should include a description of changes 

to the required actions that will ensure 

the continued damage tolerance of the 

affected structure. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

Bombardier CL–600–2B19 TR 2A–48, 

dated July 6, 2012, to Appendix A— 

Certification Requirements, of Part 2, 

Airworthiness Requirements, of the 

Bombardier CL–600–219 Maintenance 

Requirements Manual, specifies a task 

interval of 10,000 flight cycles or 144 

months in the ‘‘Task Interval’’ column, 

and a task interval of 10,000 flight 

cycles in the ‘‘Task Description’’ 

column. This proposed AD would 

require a task interval of 10,000 flight 

cycles. This difference has been 

coordinated with TCCA. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 573 products of U.S. 

registry. We also estimate that it would 

take about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$48,705, or $85 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 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.
