ACTION: Notice of proposed rulemaking

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702), 

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

CL–600–2D24 (Regional Jet Series 900), 

and CL–600–2E25 (Regional Jet Series 

1000) airplanes. This proposed AD was 

prompted by the finding of an 

uncertified main landing gear (MLG) 

inboard retraction actuator bracket pin 

installed on an in-service airplane, 

which could result in pin failure. This 

proposed AD would require inspection 

of the MLG inboard retraction actuator 

bracket for a part number, and 

replacement if necessary. We are 

proposing this AD to detect and correct 

uncertified pins in the MLG inboard 

retraction actuator bracket, which could 

result in pin failure, leading to an MLG 

extension without damping, and a 

potential for MLG structural damage 

and possible collapse during landing. 

DATES: We must receive comments on 

this proposed AD by February 18, 2014. 

ADDRESSES: You may send comments by 

any of the following methods:

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 1 / Thursday, January 2, 2014 / Proposed Rules 73 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2013–23, 

dated August 13, 2013 (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: 

An uncertified main landing gear (MLG) 

inboard retraction actuator bracket pin, part 

number (P/N) 49131–1, was found installed 

on an in-service aeroplane. Five other 

uncertified pins were also returned to the 

manufacturer. The uncertified pin, 

P/N 49131–1, is weaker than the approved 

pin, P/N 49131–3. An MLG inboard 

retraction actuator bracket pin failure could 

result in an MLG extension without damping, 

and a potential for MLG structural damage 

and possible collapse during landing. 

This [TCCA] AD mandates the inspection 

for and removal of the uncertified pins. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2013–1070. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 670BA–32–044, dated May 29, 

2013. 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. 

Costs of Compliance 

We estimate that this proposed AD 

affects 416 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. Required 

parts would cost about $0 per product. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 

operators to be $35,360, or $85 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $0, for a cost of $85 per product. 

We have no way of determining the 

number of aircraft that might need this 

action. 

According to the manufacturer, some 

of the costs of this proposed 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: 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701.

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD):

installed on an in-service airplane, which 

could result in pin failure. We are issuing 

this AD to detect and correct uncertified pins 

in the MLG inboard retraction actuator

leading to an MLG extension without 

damping, and a potential for MLG structural 

damage and possible collapse during landing.

occurs first, do an inspection of the MLG 

inboard retraction actuator bracket for any 

uncertified pin having part number (P/N) 

49131–1, in accordance with the 

Accomplishment Instructions of Bombardier

Airworthiness Directives; Eurocopter

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Eurocopter France (Eurocopter) Model 

EC120B and EC130B4 helicopters. This 

proposed AD would require replacing 

parts of the sliding door star support 

attachment assembly, depending on the 

outcome of required inspections. This 

proposed AD is prompted by a report 

that passengers in a Eurocopter 

helicopter were forced to exit through 

the pilot door after landing because they 

could not open the sliding door from the 

inside. The proposed actions are 

intended to prevent failure of the sliding 

door star support attachment, which 

could inhibit operation of a sliding door 

from inside, delaying the evacuation of 

passengers during an emergency. 

DATES: We must receive comments on 

this proposed AD by March 3, 2014. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Docket: Go to
