14 CFR Part 39 

[Docket No. FAA–2012–0420; Directorate 

Identifier 2011–NM–284–AD; Amendment 

39–17315; AD 2013–01–01] 

RIN 2120–AA64 

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain Bombardier, Inc. Model CL–600– 

2B19 (Regional Jet Series 100 & 440) 

airplanes. That AD currently requires 

revising the airplane flight manual, 

deactivating and removing certain 

hydraulic accumulators, inspecting for 

cracks on accumulators and screw caps, 

and replacing certain accumulators. For 

certain airplanes, this new AD reduces 

the compliance time for a certain 

replacement. This AD was prompted by 

reports of on-ground hydraulic 

accumulator screw cap/end cap failure. 

We are issuing this AD to detect and 

correct hydraulic accumulator screw 

cap/end cap failure, which could result 

in the loss of the associated hydraulic 

system and high-energy impact damage 

to adjacent systems and structure, and 

consequent loss of control of the 

airplane. 

DATES: This AD becomes effective July 

23, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 23, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in 

this AD as of December 22, 2011 (76 FR 

71241, November 17, 2011). 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in 

this AD as of November 4, 2010 (75 FR 

64636, October 20, 2010).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on April 19, 2012 (77 FR 

23420), and proposed to supersede AD 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011), which 

superseded AD 2010–22–02, 

Amendment 39–16481 (75 FR 64636, 

October 20, 2010). That NPRM proposed 

to correct an unsafe condition for the 

specified products. Transport Canada 

Civil Aviation, which is the aviation 

authority for Canada, has issued 

Canadian Airworthiness Directive CF– 

2010–24, dated August 3, 2010 (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: 

Seven cases of on-ground hydraulic 

accumulator screw cap/end cap failure have 

been experienced on CL–600–2B19 

aeroplanes, resulting in the loss of the 

associated hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. The lowest number of flight cycles 

accumulated at the time of failure, to date, 

has been 6991 flight cycles. 

The part numbers (P/N) of the 

accumulators currently installed on CL–600– 

2B19 aeroplanes are 601R75138–1 (08– 

60163–001 or 08–60163–002) [Hydraulic 

System No. 1, Hydraulic System No. 2, 

Inboard Brake and Outboard Brake 

accumulators] and 601R75138–3 (08–60164– 

001 or 08–60164–002) [Hydraulic System No. 

3 accumulator]. 

A detailed analysis of the calculated line 

of trajectory of a failed screw cap/end cap for 

each of the accumulators has been 

conducted, resulting in the identification of 

several areas where systems and/or structural 

components could potentially be damaged. 

Although all of the failures to date have 

occurred on the ground, an in-flight failure 

affecting such components could potentially 

have an adverse effect on the controllability 

of the aeroplane. 

This [Canadian] directive gives 

instructions to amend the Airplane Flight 

Manual (AFM), remove two accumulators 

(Hydraulic System No. 2 and No. 3) from the 

aeroplane and conduct repetitive ultrasonic 

inspections [for cracks] of the Hydraulic 

System No. 1, Inboard Brake and Outboard 

Brake accumulators that are not identified by 

the letter ‘‘T’’ after the serial number (S/N) 

on the identification plate for cracks until 

they are replaced by new accumulators P/N 

601R75139–1 (11093–4).

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Remove Compliance Time 

Comair, Inc. requested that we remove 

paragraph (n)(2) from the NPRM (77 FR 

23420, April 19, 2012). The commenter 

stated its understanding that the main 

reason for the change to paragraph (n) 

of the NPRM is to add paragraph (n)(2) 

with the intent to reduce the 

compliance schedule. However, Comair, 

Inc. reasoned that, based on the timeline 

for issuance of a final rule, the 60-day 

compliance time that was added to 

paragraph (n)(2) of the NPRM will likely 

extend the compliance time by three or 

more months beyond the existing 

compliance time for that required action 

(which is required by AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241, 

November 17, 2011)), instead of 

reducing the compliance time. 

We disagree with the request to 

remove paragraph (n)(2) of the NPRM 

(77 FR 23420, April 19, 2012) from the 

final rule. Paragraph (n) of this AD 

indicates that the required action must 

be done at the later of the times in 

paragraphs (n)(1) and (n)(2) of this AD. 

Paragraph (n)(1) of this AD includes the 

phrase, ‘‘whichever occurs first,’’ which 

requires operators to perform the action 

at the earlier of the times specified in 


ehiers on DSK2VPTVN1PROD with RULES
36408 Federal Register / Vol. 78, No. 117 / Tuesday, June 18, 2013 / Rules and Regulations 

that paragraph. Those times are tied to 

the effective date of AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241, 

November 17, 2011), and are restated 

from that AD. Therefore, we added 

paragraph (n)(2) in the NPRM as a grace 

period for operators that may already 

have exceeded the compliance time in 

paragraph (n)(1) of this AD. 

We find that the reduced compliance 

time is necessary to address the 

identified unsafe condition in a timely 

manner, and that a grace period is 

necessary to prevent unintentionally 

grounding airplanes. We have not 

changed the final rule in this regard. 

Request To Revise Paragraph (l) of the 

NPRM (77 FR 23420, April 19, 2012) 

Comair, Inc. requested that we revise 

paragraph (l) of the NPRM (77 FR 23420, 

April 19, 2012) to remove the phrase, 

‘‘with reduced compliance time for 

paragraph (n).’’ Comair, Inc. considered 

this phrase to be an error and requested 

that further explanation be provided if 

the phrase is intended to be included. 

We agree with the commenter’s 

request. We note that both paragraphs (l) 

and (m) of the NPRM (77 FR 23420, 

April 19, 2012) contained similar 

phrases. However, since no reference to 

a reduced compliance time should be 

included in those paragraphs, we have 

deleted the phrases from both 

paragraphs (l) and (m) of this final rule. 

Request To Remove References to a 

Certain AD 

Air Wisconsin Airlines Corporation 

(Air Wisconsin) requested that we revise 

the NPRM (77 FR 23420, April 19, 2012) 

to remove certain AD references 

specified in paragraphs (g), (h), (i), (j), 

and (k) of the NPRM. Air Wisconsin 

stated that those paragraphs incorrectly 

refer to a previously superseded AD (AD 

2010–22–02, Amendment 39–16481 (75 

FR 64636, October 20, 2010)), and 

should instead be replaced with the 

most recent AD being superseded (that 

is, AD 2011–23–08, Amendment 39– 

16859 (76 FR 71241, November 17, 

2011)). 

We partially agree with the 

commenter’s request. We revised the 

introductory statement of paragraphs 

(g), (h), (i), (j), and (k) of this final rule 

to specify that the requirements of those 

paragraphs are restated from AD 2011– 

23–08, Amendment 39–16859 (76 FR 

71241, November 17, 2011). 

However, we have not changed the 

compliance times specified (or 

referenced) in paragraphs (g), (h), (i), (j), 

and (k) of this AD. The actions required 

by those paragraphs were required in 

AD 2010–22–02, Amendment 39–16481 

(75 FR 64636, October 20, 2010), and 

the compliance times for those actions 

are based on the effective date of that 

AD. Those restated compliance times 

have not been changed in this final rule. 

Request To Clarify Service Information 

Reference 

Air Wisconsin requested that we 

revise paragraphs (h) and (i) of the 

NPRM (77 FR 23420, April 19, 2012) to 

clarify the added reference to revised 

service information. The commenter 

noted that those paragraphs state there 

is revised service information. Air 

Wisconsin questioned whether the 

revised service information is from AD 

2010–22–02, Amendment 39–16481 (75 

FR 64636, October 20, 2010); or AD 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011). 

We agree that clarification is 

necessary. We inadvertently specified 

that revised service information is 

included in paragraphs (h) and (i) of the 

NPRM (76 FR 71241, November 17, 

2011), when, in fact, no revised service 

information was included. Therefore, 

we have removed those references from 

paragraphs (h) and (i) of this final rule. 

Request To Include the Latest 

Temporary Revision (TR) 

Air Wisconsin requested that we 

revise the NPRM (77 FR 23420, April 

19, 2012) to include the latest TR to the 

Canadair Regional Jet AFM, CSP A–012. 

The commenter noted that paragraph (g) 

of the NPRM pertains to Canadair 

Regional Jet TR RJ/186–1, dated August 

24, 2010. Air Wisconsin requested that 

we add Canadair Regional Jet TR RJ/ 

186–2, dated July 7, 2011, as an 

approved method. 

We agree with the commenter’s 

request, and have included Canadair 

Regional Jet TR RJ/186–2, dated July 7, 

2011, in paragraph (g) of this final rule 

and in Note 1 to paragraph (g) of this 

final rule. 

Explanation of Changes Made to This 

AD 

We have removed tables 1, 2, 3, 4, and 

5 of this final rule. Instead, we have 

included the information from those 

tables in the subparagraphs of 

paragraphs (j)(1), (j)(2), (m), and (o)(3) of 

this final rule. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously— 

except for minor editorial changes. We 

have determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

23420, April 19, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 23420, 

April 19, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

about 605 products of U.S. registry. 

The actions that are required by AD 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011), and 

retained in this AD take about 33 workhours per product, at an average labor 

rate of $85 per work-hour. Required 

parts cost about $3,054 per product. 

Based on these figures, the estimated 

cost of the currently required actions is 

$5,859 per product. 

The new requirements of this AD add 

no additional economic burden. 

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, 


ehiers on DSK2VPTVN1PROD with RULES
Federal Register / Vol. 78, No. 117 / Tuesday, June 18, 2013 / Rules and Regulations 36409 

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 AD and placed it in the AD docket.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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) 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011), and 

adding the following new AD: 

2013–01–01 Bombardier, Inc.: Amendment 

39–17315. Docket No. FAA–2012–0420; 

Directorate Identifier 2011–NM–284–AD.

Thereafter, except as provided by paragraph 

(p) of this AD, no alternative actions 

specified in Canadair Regional Jet TR RJ/186– 

1, dated August 24, 2010; or Canadair 

Regional Jet TR RJ/186–2, dated July 7, 2011; 

may be approved. 

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

actions required by paragraph (g) of this AD 

may be done by inserting a copy of Canadair 

Regional Jet TR RJ/186–1, dated August 24, 

2010; or Canadair Regional Jet TR RJ/186–2, 

dated July 7, 2011; into the applicable section 

of the Canadair Regional Jet AFM, CSP A– 

012. When one of these TRs has been 

included in the general revisions of this 

AFM, the general revisions may be inserted 

into this AFM, and the TR removed, 

provided that the relevant information in the 

general revision is identical to that in 

Canadair Regional Jet TR RJ/186–1, dated 

August 24, 2010; or Canadair Regional Jet TR 

RJ/186–2, dated July 7, 2011. 

(h) Retained Deactivation of the Hydraulic 

System No. 3 Accumulator 

This paragraph restates the deactivation 

required by paragraph (h) of AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241,

Amendment of Class E Airspace; 

Tuskegee, AL 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class E 

Airspace at Tuskegee, AL, as the 

Tuskegee VOR/DME has been 

decommissioned and airspace 

reconfiguration is necessary for the 

safety and airspace management of 

Instrument Flight Rules (IFR) operations 

at Moton Field Municipal Airport. This 

action also corrects the spelling of the 

airport. 

DATES: Effective 0901 UTC, August 22, 

2013. The Director of the Federal 

Register approves this incorporation by 

reference action under title 1, Code of 

Federal Regulations, part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

History 

On March 28, 2013, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to amend Class E airspace at Moton 

Field Municipal Airport, Tuskegee, AL 

(78 FR 18928). Interested parties were 

invited to participate in this rulemaking 

effort by submitting written comments 

on the proposal to the FAA. No 

comments were received. Subsequent to 

publication the FAA found that the 

airport’s name was misspelled in the 

NPRM. This action corrects the 

misspelling from Moten to Moton. 

Except for editorial changes and the 

changes listed above, this rule is the 

same as published in the NPRM. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.9W dated August 8, 2012, 

and effective September 15, 2012, which 

is incorporated by reference in 14 CFR 

Part 71.1. The Class E airspace 

designations listed in this document 

will be published subsequently in the 

Order.
