ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This AD was prompted by a 

determination that certain flap actuators 

require restoration by installing a 

redesigned flap actuator inboard pinion 

seal. This AD requires revising the 

maintenance program by incorporating 

new airworthiness limitation tasks. We 

are issuing this AD to prevent flap 

system failure, and consequent reduced 

control of the airplane. 

DATES: This AD becomes effective 

September 10, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 10, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on April 8, 2013 (78 FR 20844). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products. 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. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Statement of Support for the NPRM (78 

FR 20844, April 8, 2013) and Request 

To Shorten Compliance Time 

The Airline Pilots Association 

International stated it supports the 

NPRM (78 FR 20844, April 8, 2013), and 

requested that we shorten the 

compliance time to ensure that the 

identified safety issue is corrected 

within the airplane fleet as soon as 

possible. 

We do not agree with the request to 

shorten the compliance time. After 

considering all the available 

information, we have determined that 

the compliance time, as proposed, 

represents an appropriate interval of 

time in which the required actions can 


tkelley on DSK3SPTVN1PROD with RULES
47530 Federal Register / Vol. 78, No. 151 / Tuesday, August 6, 2013 / Rules and Regulations 

be performed in a timely manner within 

the affected fleet, while still maintaining 

an adequate level of safety. In 

developing an appropriate compliance 

time, we considered the safety 

implications, parts availability, and 

normal maintenance schedules for 

timely accomplishment of installing the 

inboard pinion seal in the flap actuator. 

Further, we arrived at the proposed 

initial task compliance time with 

operator and manufacturer concurrence. 

To reduce the compliance time of the 

NPRM (78 FR 20844, April 8, 2013) 

would necessitate (under the provisions 

of the Administrative Procedure Act) 

reissuing the notice, reopening the 

period for public comment, considering 

additional comments subsequently 

received, and eventually issuing a final 

rule. We have determined that further 

delay of this final rule is not 

appropriate. However, if additional data 

are presented that would justify a 

shorter compliance time, we might 

consider further rulemaking on this 

issue. We have not changed this AD in 

this regard. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed—except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

20844, April 8, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 20844, 

April 8, 2013). 

Costs of Compliance 

We estimate that this AD affects 573 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Revise the maintenance program ....................... 1 work-hour × $85 per hour = $85 ..................... $0 $85 $48,705 

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 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 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 AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the MCAI, the 

regulatory evaluation, any comments 

received, and other information. The
