Identifier 2011–NM–230–AD] 

RIN 2120–AA64 

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies 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 existing AD 

currently requires operators to assign 

serial numbers or part numbers to 

certain landing gear parts; and to 

establish the number of landings on the 

parts, if necessary. The existing AD also 

requires operators to revise the 

Airworthiness Limitations Section 

(ALS) of the Instructions for Continued 

Airworthiness (ICA) to reflect the new 

life limits of the landing gear parts. 

Since we issued that AD, additional 

landing gear parts have been identified 

that need serialization. This proposed 

AD would add airplanes to the 

applicability; require operators to assign 

serial numbers or part numbers to 

certain additional landing gear parts, to 

establish the number of landings on the 

parts, if necessary; and record in all 

required airplane technical records and 

manuals the new part numbers, serial 

numbers, and landings assigned to these 

parts. We are proposing this AD to 

prevent life-limited landing gear parts 

from being used beyond their safe-life 

limits, which could lead to collapse of 

the landing gear. 

DATES: We must receive comments on 

this proposed AD by February 13, 2014.

Discussion 

On July 11, 2005, we issued AD 2005– 

15–04, Amendment 39–14193 (70 FR 

43032, July 26, 2005). That AD required 

actions intended to address an unsafe 

condition on the products listed above. 

Since we issued AD 2005–15–04, 

Amendment 39–14193 (70 FR 43032, 

July 26, 2005), Transport Canada Civil 

Aviation (TCCA), which is the 

airworthiness authority for Canada, has 

issued Canadian Airworthiness 

Directives CF–2003–18R2, dated 

September 28, 2011; CF–2003–20R1, 

dated September 28, 2011; and CF– 

2003–21R2, dated September 28, 2011; 

(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: 

Certain landing gear parts that are listed in 

the aeroplane model Airworthiness 

Limitations Section, as safe life items with 

structural life limits, could be rotable and 

may not have been serialized, making 

tracking difficult. This [Canadian 

airworthiness] directive mandates that such 

parts be serialized. This [Canadian 

airworthiness] directive also provides the 

procedure to determine the number of 

landings for those parts where the service 

history cannot be established. 

* * * * * 

[T]his [Canadian Airworthiness] directive 

* * * mandate[s] serialization of * * * 

additional landing gear parts. 

This proposed AD would also add 

airplanes to the applicability. The 

unsafe condition is using life-limited 

landing gear parts beyond their safe-life 

limits, which could lead to collapse of 

the landing gear. 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–2013–1065. 

Relevant Service Information

79330 Federal Register / Vol. 78, No. 250 / Monday, December 30, 2013 / Proposed Rules 

• Bombardier Service Bulletin 604– 

32–014, Revision 02, dated May 9, 2011, 

including Appendix 1, dated May 9, 

2011, and Service Bulletin Information 

Sheet, dated July 6, 2010 (for Model CL– 

600–2B16 (CL–604 Variant) airplanes). 

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. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

For Model CL–600–2B16 (CL–604 

Variant) airplanes, the MCAI specifies 

serial numbers 5301 through 5595 

inclusive; however, the actions of the 

MCAI address only serial numbers 5301 

through 5573 inclusive, 5579, and 5595. 

Consequently, we have specified the 

proposed applicability as serial numbers 

5301 to 5573 inclusive, 5579, and 5595. 

We have coordinated this difference 

with TCCA. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 419 products of U.S. 

registry. 

The actions that are required by AD 

2005–15–04, Amendment 39–14193 (70 

FR 43032, July 26, 2005), and retained 

in this proposed AD take up to 13 workhours per product, at an average labor 

rate of $85 per work hour. Based on 

these figures, the estimated cost of the 

currently required actions is $1,105 per 

product. 

We estimate that it would take about 

9 work-hours per product to comply 

with the new basic requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$320,535, or $765 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 proposed 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing airworthiness directive (AD) 

2005–15–04, Amendment 39–14193 (70 

FR 43032, July 26, 2005), and adding the 

following new AD: 

Bombardier, Inc.: Docket No. FAA–2013– 

1065; Directorate Identifier 2011–NM– 

230–AD. 

(a) Comments Due Date 

We must receive comments by February 

13, 2014. 

(b) Affected ADs 

This AD supersedes AD 2005–15–04, 

Amendment 39–14193 (70 FR 43032, July 26, 

2005). 

(c) Applicability 

This AD applies to Bombardier, Inc. 

airplanes, certificated in any category, as 

identified in paragraphs (c)(1) through (c)(4) 

of this AD. 

(1) Model CL–600–1A11 (CL–600) 

airplanes, serial numbers 1004 through 1085 

inclusive. 

(2) Model CL–600–2A12 (CL–601) 

airplanes, serial numbers 3001 through 3066 

inclusive; 

(3) Model CL–600–2B16 (CL–601–3A and 

CL–601–3R Variants) airplanes, serial 

numbers 5001 through 5194 inclusive. 

(4) Model CL–600–2B16 (CL–604 Variant) 

airplanes, serial numbers 5301 through 5573 

inclusive, 5579, and 5595. 

(5) 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 (r) of this AD. The request 

should include a description of changes to 

the required actions that will ensure the 

continued damage tolerance of the affected 

structure. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32, Landing Gear. 

(e) Reason 

This AD was prompted by reports that 

landing gear parts that have safe-life limits 

but do not have serial numbers or part 

numbers can be removed from one landing 

gear and re-installed on another, making 

tracking difficult. We are issuing this AD to 

prevent life-limited landing gear parts from 

being used beyond their safe-life limits, 

which could lead to collapse of the landing 

gear. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done.

Service Bulletin 600–0710, Revision 01, 

dated December 15, 2003; and Bombardier 

Service Bulletin 601–0546, Revision 01, 

dated December 15, 2003; as having a 

compliance time of ‘‘five years for the parts 

listed in Part A’’: Within 60 months after 

August 30, 2005 (the effective date of AD 

2005–15–04, Amendment 39–14193 (70 FR 

43032, July 26, 2005)). 

(2) For parts identified in Bombardier 

Service Bulletin 600–0710, Revision 01, 

dated December 15, 2003; and Bombardier 

Service Bulletin 601–0546, Revision 01, 

dated December 15, 2003; as having a 

compliance time of ‘‘ten years for the parts 

listed in Part B’’: Within 120 months after 

August 30, 2005 (the effective date of AD 

2005–15–04, Amendment 39–14193 (70 FR

effective date of AD 2005–15–04, 

Amendment 39–14193 (70 FR 43032, July 26, 

2005)). 

Note 1 to paragraph (g) of this AD: The 

Bombardier service bulletins refer to the 

Messier-Dowty service bulletins in table 1 to 

paragraph (g) of this AD as additional sources 

of service information for adding part 

numbers or serial numbers by vibro-peening 

the numbers on main landing gear (MLG) and 

nose landing gear (NLG) components that do 

not have them; and for determining the 

number of landings for parts without a part 

number or serial number on which the time 

since new (TSN) and cycles since new (CSN) 

have not been tracked.

2005), with revised affected airplanes. Except 

for Model CL–600–2B16 airplanes having 

serial numbers 5314 through 5595 inclusive: 

At the applicable time specified in paragraph 

(g) of this AD, if a component does not have 

a serial number and the CSN or TSN were not 

tracked, use the formula in the applicable 

Messier-Dowty service bulletin in table 1 to

Identifier 2013–NM–021–AD]

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2000–12– 

12, for certain Airbus Model A300, 

A300–600, and A310 series airplanes. 

AD 2000–12–12 currently requires 

inspecting to detect cracks in the lower 

spar axis of the nacelle pylon between 

ribs 9 and 10, and repair if necessary. 

AD 2000–12–12 also provides for 

optional modification of the pylon, 

which terminates the inspections for 

Model A300 series airplanes. Since we 

issued AD 2000–12–12, we have 

received reports of cracking of the lower 

pylon spar after accomplishing the 

existing modification and have 

determined that shorter initial and 

repetitive inspection compliance times 

are necessary to address the identified 

unsafe condition. This proposed AD 

would reduce the initial and repetitive 

inspection compliance times. We are 

proposing this AD to detect and correct 

fatigue cracking, which could result in 

reduced structural integrity of the lower 

spar of the nacelle pylon. 

DATES: We must receive comments on 

this proposed AD by February 13, 2014. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: (202) 493–2251. 

• Mail: U.S. Department of 

Transportation, Docket Operations, M–
