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–600–2E25 

(Regional Jet Series 1000) airplanes. 

This proposed 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 proposed 

AD would require revising the 

maintenance or inspection program, as 

applicable, to incorporate a 

maintenance task for an operational 

check of the electro-mechanical actuator 

(EMA) and release mechanism of the 

alternate extension system (AES) for the 

nose landing gear (NLG) and main 

landing gear (MLG). We are proposing 

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: We must receive comments on 

this proposed AD by March 9, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

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 [TCCA] 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 by searching for 

and locating Docket No. FAA–2015– 

0074. 

Related Service Information 

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 


emcdonald on DSK67QTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 3499 

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 this same 

type design. 

This AD requires revisions to certain 

operator maintenance documents to 

include new actions (e.g., inspections). 

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 this AD, the operator 

may not be able to accomplish the 

actions 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 paragraph (i)(1) 

of this AD. The request should include 

a description of changes to the required 

inspections that will ensure the 

continued operational safety of the 

airplane. 

Costs of Compliance 

We estimate that this proposed AD 

affects 35 airplanes 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 

this proposed 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 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.

on certain airplanes. This proposed AD 

would require a one-time detailed 

inspection of the oblique frame 67–2 for 

any cracking, and repair if necessary. 

We are proposing this AD to detect and 

correct such cracking, which could lead 

to failure of the oblique frame 67–2, and 

consequent loss of the structural 

integrity of the tail section.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2014–0039, dated February 20, 

2014 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all Fokker 

Services B.V. Model F.28 Mark 0070 

and 0100 airplanes. The MCAI states: 

Service experience has shown that cracks 

can occur in oblique frame 67–2 in the tail 

section on aeroplanes with more than 29 000 

flight cycles (FC). 

This condition, if not detected and 

corrected, can result in an exponential crack 

growth rate, possibly leading to failure of the 

oblique frame 67–2 over a certain length and 

consequent loss of the structural integrity of 

the tail section of the aeroplane. 

For the reasons described above, this 

[EASA] AD requires a one-time [detailed] 

inspection of the oblique frame 67–2 for 

cracks and, depending on findings, 

accomplishment of a repair. 

Repetitive inspections are planned to be 

incorporated into a revision of Fokker 

Services Report SE–623, which is part of the 

Airworthiness Limitations Section of the 

Instructions for Continued Airworthiness, for 

which a separate [EASA] AD is expected to 

be published. 

Fokker Services All Operators Message
