without substantive change from those 

previously issued. It is unlikely that 

prior public comment would result in a 

significant change from the substance 

contained herein. Therefore, because a 

delay would significantly affect the 

certification of the airplane, the FAA 

has determined that prior public notice 

and comment are unnecessary and 

impracticable, and good cause exists for 

adopting these special conditions upon 

issuance. The FAA is requesting 

comments to allow interested persons to 

submit views that may not have been 

submitted in response to the prior 

opportunities for comment described 

above.

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are revising an existing 

airworthiness directive (AD) for certain 

Bombardier Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes; all Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) 

airplanes; all Model CL–600–2D15 

(Regional Jet Series 705) airplanes; and 

all Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. That AD currently 

requires replacing certain water 

accumulator assemblies having a certain 

part installed on the pitot and static 

lines of the air data computer (ADC). 

This new AD corrects an erroneous 

service document number and removes 

the other erroneously cited service 

document from that AD. This new AD 

was prompted by an error that was 

discovered in one service document 

number, and a determination that credit 

for accomplishing actions in another 

erroneously cited service document 

should be removed from that AD. We 

are issuing this AD to prevent pitotstatic tubing from becoming partially or 

completely blocked by water, which 

could result in erroneous airspeed and 

altitude indications and consequent loss 

of control of the airplane. 

DATES: This AD becomes effective 

December 18, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 23, 2011 (76 FR 64801, 

October 19, 2011).

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 18, 2012 (77 FR 

23169), and proposed to revise AD 

2011–21–07, Amendment 39–16830 (76 

FR 64801, October 19, 2011). That 

NPRM proposed to correct an unsafe 

condition for the specified products. 

Since we issued AD 2011–21–07, 

Amendment 39–16830 (76 FR 64801, 

October 19, 2011), an error was 

discovered in the document number 

specified in paragraph (i), ‘‘Credit for 

Actions Accomplished in Accordance 

with Previous Service Information,’’ of 

that AD. The citation in that paragraph 

should have read ‘‘Bombardier Service 

Bulletin 601R–34–147, Revision A, 

dated November 3, 2009.’’ Additionally, 

we have determined that ‘‘Bombardier 

Service Bulletin 670BA–34–147, dated 

April 1, 2009,’’ was incorrectly included 

in AD 2011–21–07 and should be 

removed from paragraph (i) of that AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Request for Credit for Previous Actions 

Air Wisconsin (AWI) requested that 

we revise the NPRM (77 FR 23169, April 

18, 2012) to continue to give credit for 

previous actions for airplanes modified 

using Bombardier Service Bulletin 

601R–34–147, dated April 1, 2009. AWI 

provided the following reasons for its 

request. 

• AWI stated that in the original issue 

of Bombardier Service Bulletin 601R– 

34–147, dated April 1, 2009, for airplane 

serial numbers (S/N) 7003 through 7890, 

this service information called for the 

use of a parts kit that was different from 

the parts kit used for airplane S/Ns 7891 

and subsequent. AWI stated that it 

discovered, during the use of that 

service information, that there was no 

difference between the two groups of 

airplanes. AWI stated that airplane S/Ns 

7891 and subsequent needed to use the 

same parts kit as airplane S/Ns 7003 

through 7890, with the only difference 

being that the kit for airplane S/Ns 7891 

and subsequent lacked two tee fittings, 

part number AS1033W040406, which 

were contained in the kits for airplane 

S/Ns 7003 through 7891. AWI stated 

that, as a result of its discovery, 


erowe on DSK2VPTVN1PROD with 
67560 Federal Register / Vol. 77, No. 219 / Tuesday, November 13, 2012 / Rules and Regulations 

Bombardier Service Bulletin 601R–34– 

147, dated April 1, 2009, was revised to 

Bombardier Service Bulletin 601R–34– 

147, Revision A, dated November 3, 

2009, eliminating the reference to these 

two different groups of airplanes and 

correcting the materials kit to include 

the tee fittings. 

• AWI stated that Bombardier Service 

Bulletin 601R–34–147, Revision A, 

dated November 3, 2009, does nothing 

to change parts kits or instructions for 

airplane S/Ns 7003 through 7890, but 

only makes the correction for airplane 

S/Ns 7891 and subsequent. 

• AWI stated that airplane S/Ns 7891 

and subsequent modified with the use 

of Bombardier Service Bulletin 601R– 

34–147, dated April 1, 2009, that used 

the additional tee fittings are in 

compliance with Bombardier Service 

Bulletin 601R–34–147, Revision A, 

dated November 3, 2009. 

• AWI stated that it has completed 

this modification on its fleet of 71 

affected airplanes and that airplane 

S/Ns 7891 and subsequent used the 

necessary tee fittings called for in 

Bombardier Service Bulletin 601R–34– 

147, Revision A, dated November 3, 

2009. 

• AWI stated that Bombardier Service 

Bulletin 601R–34–147, Revision A, 

dated November 3, 2009, clearly states 

on the transmittal, ‘‘The changes in this 

revision have no effect on aircraft that 

have incorporated a previous issue of 

the service bulletin.’’ 

We do not agree to provide credit for 

previous actions done using Bombardier 

Service Bulletin 601R–34–147, dated 

April 1, 2009. We issued the NPRM (77 

FR 23169, April 18, 2012) due to an 

error that was discovered in AD 2011– 

21–07, Amendment 39–16830 (76 FR 

64801, October 19, 2011), in a service 

document number, and also due to a 

provision incorrectly giving credit for 

accomplishing previous actions in 

another erroneously cited service 

document. Credit for previous actions 

using Bombardier Service Bulletin 

601R–34–147, dated April 1, 2009, is 

not appropriate because a modification 

kit requiring tee fittings was missing 

from that service information. In order 

to comply with the intent of the AD, 

Bombardier Service Bulletin 601R–34– 

147, Revision A, dated November 3, 

2009, corrected the kit error, and hence, 

is mandated by this revised AD to 

correct the unsafe condition. Under the 

provisions of paragraph (j) of this AD, 

however, we will consider requests for 

approval of an alternative method of 

compliance (AMOC) if sufficient data 

are submitted to substantiate that a 

different method of compliance would 

provide an acceptable level of safety. 

We have not changed the AD in this 

regard. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the 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 (77 FR 

23169, April 18, 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 23169, 

April 18, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

about 1,041 products of U.S. registry. 

The new requirements of this AD add 

no additional economic burden. The 

current costs for this AD are repeated for 

the convenience of affected operators. 

The actions that are required by AD 

2011–21–07, Amendment 39–16830 (76 

FR 64801, October 19, 2011), and 

retained in this AD take about 2 workhours per product, at an average labor 

rate of $85 per work-hour. Required 

parts cost about $1,200 per product. 

Based on these figures, the estimated 

cost of the currently required actions is 

$1,370 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket
