RIN 2120–AA64 

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2013–16– 

08 for certain Bombardier, Inc. Model 

CL–600–2C10 (Regional Jet Series 700, 

701, & 702) airplanes, Model CL–600– 

2D15 (Regional Jet Series 705) airplanes, 

and Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. AD 2013–16–08 

required inspection of the main landing 

gear (MLG) retraction actuator 

components; corrective actions if 

necessary; and, for certain retraction 

actuators, installation of a new jam nut. 

This new AD continues to require those 

actions. This AD was prompted by a 

determination that a certain part was 

incorrectly identified in a certain 

section of AD 2013–16–08. We are 

issuing this AD to prevent 

disconnection of the MLG retraction 

actuator, which could result in 

extension of the MLG without damping, 

and consequent structural damage and 

collapse of the MLG during landing. 

DATES: This AD becomes effective 

December 12, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 24, 2013 (78 FR 51055, 

August 20, 2013).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2013–16–08, 

Amendment 39–17546 (78 FR 51055, 

August 20, 2013). AD 2013–16–08 

applied to certain Bombardier, Inc. 

Model CL–600–2C10 (Regional Jet 

Series 700, 701, & 702) airplanes, Model 

CL–600–2D15 (Regional Jet Series 705) 

airplanes, and Model CL–600–2D24 

(Regional Jet Series 900) airplanes. The 

NPRM published in the Federal 

Register on July 25, 2014 (79 FR 43322). 

The NPRM was prompted by a 

determination that a certain part was 

incorrectly identified in a certain 

section of AD 2013–16–08. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2011–36R1, 

dated October 3, 2012 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–2C10 (Regional Jet Series 700, 701, 

& 702) airplanes, Model CL–600–2D15 

(Regional Jet Series 705) airplanes, and 

Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. The MCAI states: 

Corrosion of the main landing gear (MLG) 

retraction actuator components was found inservice, either at the interface of the rod end 

and the piston or at the bracket and its 

related pins. This can cause the MLG 

retraction actuator to disconnect, leading to 

an MLG extension without damping, and a 

potential for MLG structural damage and 

possible collapse during landing. 

This [Canadian] AD mandates the 

inspection and rectification [corrective 

action] of the MLG retraction actuator 

components. 

This revision is to mandate [, for certain 

MLG retraction actuators,] the installation of 

the new retraction actuator jam nut. This 

revision also corrects the background 

information and updates Service Bulletin 

(SB) references. 

You may examine the MCAI in the AD 

docket on the Internet at http:// 

www.regulations.gov/ 

#!documentDetail;D=FAA-2014-0483- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 43322, July 25, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data 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 (79 FR 

43322, July 25, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 43322, 

July 25, 2014). 

Costs of Compliance 

We estimate that this AD affects 391 

airplanes of U.S. registry. 

The actions required by AD 2013–16– 

08, Amendment 39–17546 (78 FR 

51055, August 20, 2013), and retained in 

this AD take up to 16 work-hours per 

product, at an average labor rate of $85 

per work-hour. Required parts cost 

about $1,018 per product. Based on 

these figures, the estimated cost of the 

actions that are required by AD 2013– 

16–08 is $2,378 per product. 

The new requirements of this AD add 

no additional economic burden. 

According to the manufacturer, some 

of the costs of this 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: 


rmajette on DSK2VPTVN1PROD with RULES
Federal Register / Vol. 79, No. 216 / Friday, November 7, 2014 / Rules and Regulations 66281 

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.
