ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2E25 

(Regional Jet Series 1000) airplanes. 

This AD was prompted by a 

determination that without an effective 

maintenance task to maintain the 

airplane’s inherent level of safety, there 

is a potential that a dormant failure of 

the alternate release system of the 

landing gear could occur. This AD 

requires revising the maintenance or 

inspection program, as applicable, to 

incorporate a maintenance task for an 

operational check of the electromechanical actuator and release 

mechanism of the alternate extension 

system for the nose landing gear and 

main landing gear. We are issuing this 

AD to prevent failure of the alternate 

release system of the landing gear, 

which could prevent the landing gear 

from extending during a failure of the 

normal landing gear extension system. 

DATES: This AD becomes effective June 

4, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of June 4, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Bombardier, Inc. Model 

CL–600–2E25 (Regional Jet Series 1000) 

airplanes. The NPRM published in the 

Federal Register on January 23, 2015 

(80 FR 3498). 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2014–16, 

dated June 11, 2014 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–2E25 (Regional Jet Series 1000) 

airplanes. The MCAI states: 

During a design review, an error was 

identified which led to the development of 

a new certification maintenance requirement 

(CMR) task. Without an effective 

maintenance task to maintain the aeroplane’s 

inherent level of safety, there is a potential 

that a dormant failure of the alternate release 

system of the landing gear could occur. 

Failure of the landing gear alternate release 

system could prevent the landing gear from 

extending in the case of a failure of the 

normal landing gear extension system. 

This [Canadian] AD mandates the 

incorporation of a new maintenance task to 

ensure operation of the landing gear alternate 

extension system. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov/

#!documentDetail;D=FAA-2015-0074- 

0003. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 3498, January 23, 2015) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant 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 (80 FR 3498, 

January 23, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 3498, 

January 23, 2015). 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc. has issued 

Temporary Revision (TR) ALI–0472, 

dated February 27, 2014, to Section 1– 

32 of Part 2, Bombardier Airworthiness 

Limitations, of the CRJ Series Regional 

Jet Maintenance Requirements Manual, 

CSP B–053. This service information 

describes a maintenance task for an 

operational check of the electromechanical actuator and release 

mechanism of the alternate extension 

system for the nose landing gear and 

main landing gear. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. This service 

information is reasonably available at 

http://www.regulations.gov by searching 

for and locating Docket No. FAA–2015–

0074. Or see ADDRESSES for other ways 

to access this service information. 

Costs of Compliance 

We estimate that this AD affects 35 

airplanes of U.S. registry. 

We also estimate that it will take 

about 1 work-hour per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Based on these figures, 

we estimate the cost of this AD on U.S. 

operators to be $2,975, 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 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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–1A11 

(CL–600), CL–600–2A12 (CL–601), and 

CL–600–2B16 (CL–601–3A, CL–601–3R, 

and CL–604 Variants) airplanes. This 

AD was prompted by a determination 

that the forward lugs of the flap hinge 

box might not conform to engineering 

drawings, which could result in 

premature fatigue cracking. This AD 

requires revising the maintenance or 

inspection program to include new 

airworthiness limitations tasks; and 

measuring the forward lug edge distance 

of each flap hinge box, inspecting for 

cracking and damage (i.e., deformation 

or bearing failure) of the forward lug 

edge of each flap hinge box, and 

repairing any cracking or damage if 

necessary. We are issuing this AD to 

detect and correct non-conforming flap 

hinge box forward lugs, which could 

result in failure of the lugs and 

detachment of the flap hinge box and 

consequent detachment of the flap 

surface. 

DATES: This AD becomes effective June 

4, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Bombardier, Inc. Model 

CL–600–1A11 (CL–600), CL–600–2A12 

(CL–601), and CL–600–2B16 (CL–601– 

3A, CL–601–3R, and CL–604 Variants) 

airplanes. The NPRM published in the 

Federal Register on August 4, 2014 (79 

FR 45140). The NPRM was prompted by 

a determination that the forward lugs of 

the flap hinge box might not conform to 

engineering drawings, which could 

result in premature fatigue cracking. 

The NPRM proposed to require revising 

the maintenance or inspection program 

to include new airworthiness 

limitations tasks; and measuring the 

forward lug edge distance of each flap 

hinge box, inspecting for cracking and 

damage (i.e., deformation or bearing 

failure) of the forward lug edge of each 

flap hinge box, and repairing any 

cracking or damage if necessary. We are 

issuing this AD to detect and correct 

non-conforming flap hinge box forward 

lugs, which could result in failure of the 

lugs and detachment of the flap hinge 

box and consequent detachment of the 

flap surface. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2014–01, 

dated January 3, 2014 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–1A11 (CL–600), CL–600–2A12 (CL– 

601), and CL–600–2B16 (CL–601–3A, 

CL–601–3R, and CL–604 Variants) 

airplanes. The MCAI states: 

The aeroplane manufacturer has 

determined that the flap hinge box forward 

lugs edge distance may not conform to the 

engineering drawings. Non-conforming flap 

hinge box forward lugs may result in 

premature fatigue cracking. 

Failure of the lugs could lead to the 

detachment of the flap hinge box and 

consequently the detachment of the flap 

surface. The loss of a flap surface could 

adversely affect the continued safe operation 

of the aeroplane. 

This [Canadian] AD mandates the 

incorporation of new Time Limits/

Maintenance Checks (TLMC) Airworthiness 

Limitations (AWL) tasks, and the 

measurement [and inspection for cracking 

and damage] of the forward lug edge distance 

of each flap hinge-box and rectification as 

required. 

Corrective actions include repairing 

damage and cracking. You may examine 

the MCAI in the AD docket on the 

Internet at http://www.regulations.gov/
