Identifier 2012–NM–111–AD] 

RIN 2120–AA64 

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Bombardier, Inc. Model CL– 

600–2B19 (Regional Jet Series 100 & 

440) airplanes. The NPRM proposed to 

require revising the maintenance or 

inspection program to incorporate 

revised tasks specified in certain 

temporary revisions (TRs) to the 

airplane airworthiness limitations 

(AWLs). The NPRM was prompted by 

the need for more stringent inspection 

requirements for certain affected 

components. This action revises the 

NPRM by proposing to require revising 

the maintenance or inspection program 

to incorporate certain revised AWL 

tasks instead of TRs, and by proposing 

to require repairs of affected 

components. We are proposing this 

supplemental NPRM (SNPRM) to detect 

and correct fatigue cracking in the 

affected components, which could 

result in loss of structural integrity. 

Since these actions impose an 

additional burden over those proposed 

in the NPRM, we are reopening the 

comment period to allow the public the 

chance to comment on these proposed 

changes. 

DATES: We must receive comments on 

this SNPRM by December 11, 2015.

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Bombardier, Inc. Model 

CL–600–2B19 (Regional Jet Series 100 & 

440) airplanes. The NPRM published in 

the Federal Register on October 16, 

2012 (77 FR 63282). The NPRM was 

prompted by a revision to the airplane 

AWLs to introduce more stringent 

inspection requirements on certain 

affected components. The NPRM 

proposed to require revising the 

maintenance or inspection program to 

incorporate revised AWL tasks specified 

in certain TRs. 

Actions Since Previous NPRM (77 FR 

63282, October 16, 2012) Was Issued 

Since we issued the NPRM (77 FR 

63282, October 16, 2012), we have 

determined that a repair requirement 

should be added to this SNPRM to 

correct fatigue cracking in the affected 

components.

this SNPRM. 

Comments 

We gave the public the opportunity to 

participate in developing this proposed 

AD. We considered the comments 

received. 

Requests To Reduce the Number of 

Inspections 

Skywest Airlines (Skywest) and 

Expressjet Airlines (Expressjet) 

requested that we reduce the number of 

inspections proposed by the NPRM (77 

FR 63282, October 16, 2012) by 

specifying the AWLs in lieu of the TRs 

referenced in the NPRM. Skywest and 

Expressjet stated that many of the TRs 

have already been incorporated into the 

maintenance program; the proposed 

requirements would therefore create 

difficulty in tracking TRs for 

compliance because of the many 

anticipated alternative methods of 

compliance (AMOCs) that would be 

needed. Expressjet stated that the large 

number of proposed inspections will 

create a significant burden on the 

operator. 

Bombardier requested that we specify 

the AWLs and cited an example of two 

TRs issued for the same AWL. 

Air Wisconsin (AWI) provided 

specific references to TRs that have been 

superseded by subsequently published 

TRs and requested that we revise the 

NPRM (77 FR 63282, October 16, 2012) 

to reference revised TRs that address the 

identified AWLs. 

We agree with the commenters’ 

requests to specify the AWLs instead of 

the TRs. The entirety of each TR does 

not need to be mandated. By specifying 

the AWLs, we also eliminate AWI’s 

concern over TRs that have been 

superseded. We have revised paragraph 

(g) of this SNPRM to remove the TRs 

and specify the AWLs that we propose 

to be incorporated into the maintenance 

or inspection program, as applicable. 

Request To Change Compliance Times 

for Tasks Without Phase-in Schedules 

AWI requested that, for those tasks 

without specific phase-in schedules, we 

change the compliance times to the 

times specified in the applicable TR, or 

‘‘within 1,000 flight cycles after the 

effective date of this AD,’’ whichever 

occurs later. AWI stated that although 

most of the tasks have phase-in 

schedules, some do not; therefore, the 

ability to perform these tasks on an 

entire fleet within the 60 days specified 

in the NPRM (77 FR 63282, October 16, 

2012) may not be realistic. 

We agree with the commenter’s 

request to specify phase-in schedules for 

the AWL tasks without specific phasein schedules. As stated previously, we 

revised paragraph (g) of this SNPRM to 

reference the AWLs in lieu of the TRs. 

We revised paragraph (h) of this SNPRM 

to specify where to locate compliance 

times for tasks with phase-in schedules 

and for those without phase-in 

schedules. In addition, new paragraph 

(h)(2) of this SNPRM provides a grace 

period of ‘‘within 1,000 flight cycles 

after the effective date of this AD.’’ 

Requests Regarding Previously 

Approved Repairs 

AWI requested that we approve 

AMOCs for the intervals and/or 

methods contained in technical repair 

data, e.g., repair engineering orders 


srobinson on DSK5SPTVN1PROD with PROPOSALS
65668 Federal Register / Vol. 80, No. 207 / Tuesday, October 27, 2015 / Proposed Rules 

(REOs) or generic repair engineering 

orders (GREOs) that have been approved 

previously by Transport Canada Civil 

Aviation (TCCA). AWI stated that many 

of these TCCA-approved REOs or 

GREOs have alternative inspection 

intervals that differ from the applicable 

AWL tasks stated in the TRs or the tasks 

contained within Appendix B— 

Airworthiness Limitations, of Part 2, 

Airworthiness Requirements, of the 

Bombardier CL–600–2B19 MRM CSP A– 

053. 

Skywest and Expressjet requested that 

we allow previous AWL task repairs 

that have been approved by Bombardier, 

Inc.’s TCCA Design Approval 

Organization (DAO) in the inspection 

areas. Skywest and Expressjet stated 

that this will reduce the number of 

AMOCs needed for previous repairs. 

We agree with the commenters’ 

requests regarding previously approved 

repairs. We agree to include a provision 

in this SNPRM to allow for previously 

approved repairs in the inspection area 

that were approved by the Manager, 

New York Aircraft Certification Office, 

ANE–170, FAA; or TCCA; or 

Bombardier, Inc.’s TCCA DAO. We have 

added this provision in paragraph (k) of 

this SNPRM. 

Request To Use Future Revisions of 

AWLs 

Expressjet requested that we allow the 

use of future revisions of the identified 

AWL tasks, provided they are approved 

by TCCA. 

We disagree to allow the use of future 

revisions of the identified AWL tasks as 

a method of compliance with this 

SNPRM. When referring to a specific 

document in an AD, using the phrase 

‘‘or later approved revisions’’ violates 

Office of the Federal Register (OFR) 

regulations for approving materials that 

are incorporated by reference in rules. 

See 1 CFR 51.1(f). In general terms, we 

are required by these OFR regulations to 

either publish the service document 

contents as part of the actual AD 

language, or submit the service 

document to the OFR for approval as 

‘‘referenced’’ material. In the latter case, 

we may only refer to such material in 

the text of an AD; the AD may refer to 

the service document only if the OFR 

approved it for incorporation by 

reference. 

To allow operators to use later 

revisions of the referenced document 

(issued after publication of the AD), 

either we must revise the AD to 

reference specific later revisions, or 

operators must request approval to use 

later revisions as an AMOC under the 

provisions of paragraph (k) of this 

SNPRM. Therefore, affected operators 

may request approval to use a later 

revision of the referenced AWL tasks as 

an AMOC using the procedures 

specified in paragraph (k) of this 

SNPRM provided an adequate level of 

safety is maintained. We have not 

changed this SNPRM in this regard. 

Request To Permit Removal of TR From 

Bombardier CL–600–2B19 MRM 

Skywest requested that we permit 

removal of the TR when the required 

maintenance action is incorporated into 

an MRM revision. Skywest stated that 

referring to each TR becomes 

problematic because a standard revision 

of the MRM, when published, states that 

the incorporated TRs are to be removed 

and discarded. 

As stated previously, we have revised 

paragraph (g) of this SNPRM to remove 

the TRs and specify the AWLs that we 

propose to be incorporated into the 

maintenance or inspection program, as 

applicable. Therefore, it is unnecessary 

to change this SNPRM in this regard. 

FAA’s Determination and Requirements 

of This SNPRM 

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. 

Certain changes described above 

expand the scope of the NPRM (77 FR 

63282, October 16, 2012). As a result, 

we have determined that it is necessary 

to reopen the comment period to 

provide additional opportunity for the 

public to comment on this SNPRM. 

This SNPRM proposes to require 

revisions to certain operator 

maintenance documents to include new 

inspections. Compliance with these 

inspections is required by section 

91.403(c) of the Federal Aviation 

Regulations (14 CFR 91.403(c)). For 

airplanes that have been previously 

modified, altered, or repaired in the 

areas addressed by these inspections, an 

operator might not be able to 

accomplish the inspections described in 

the revisions. In this situation, to 

comply with 14 CFR 91.403(c), the 

operator must request approval of an 

AMOC in accordance with the 

provisions of paragraph (k) of this 

SNPRM. The request should include a 

description of changes to the required 

inspections that will ensure the 

continued damage tolerance of the 

affected structure. 

Costs of Compliance 

We estimate that this SNPRM affects 

575 airplanes of U.S. registry. 

We estimate that it would take about 

1 work-hour per product to comply with 

the requirements of this SNPRM. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this SNPRM on U.S. operators to 

be $48,875, 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.

ACTION: Partial withdrawal of notice of 

proposed rulemaking. 

SUMMARY: This document withdraws a 

portion of the notice of proposed 

rulemaking published in the Federal 

Register on September 26, 2006 (71 FR 

56072). The withdrawn portion relates 

to certain general definitions for 

purposes of section 141 of the Internal 

Revenue Code and the treatment of 

partnerships for purposes of section 

145(a). 

DATES: As of October 27, 2015, the

published in the Federal Register on 

September 26, 2006 (71 FR 56072) is

SUPPLEMENTARY INFORMATION: 

Background 

On September 26, 2006, the 

Department of the Treasury and the IRS 

published in the Federal Register 

proposed regulations (71 FR 56072; 

REG–140379–02, REG–142599–02) (the 

Proposed Regulations) that would 

amend certain regulations under 

sections 141 and 145. The Proposed 

Regulations include, among other 

provisions, certain general definitions 

for purposes of the private business tests 

under section 141 and rules regarding 

the treatment of certain partnerships for 

purposes of the modified private 

business tests and the ownership test 

under section 145. This document 

withdraws these general definitions and 

the provision relating to the treatment of 

partnerships for purposes of section 

145, because these concepts either are 

unnecessary or are otherwise addressed 

as a result of other revisions to the 

remaining portions of the Proposed 

Regulations that are adopted as final 

regulations published elsewhere in this 

edition of the Federal Register.
