(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain corrective 

actions from a manufacturer, the action must 

be accomplished using a method approved 

by the Manager, International Section, 

Transport Standards Branch, FAA; or the 

European Aviation Safety Agency (EASA); or 

Airbus’s EASA Design Organization 

Approval (DOA). If approved by the DOA, 

the approval must include the DOAauthorized signature. 

(3) Required for Compliance (RC): If any 

service information contains procedures or 

tests that are identified as RC, those 

procedures and tests must be done to comply 

with this AD; any procedures or tests that are 

not identified as RC are recommended. Those 

procedures and tests that are not identified 

as RC may be deviated from using accepted 

methods in accordance with the operator’s 

maintenance or inspection program without 

obtaining approval of an AMOC, provided 

the procedures and tests identified as RC can 

be done and the airplane can be put back in 

an airworthy condition. Any substitutions or 

changes to procedures or tests identified as 

RC require approval of an AMOC.

SUPPLEMENTARY INFORMATION: 

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–600–1A11 (CL–600), CL–600–2A12 

(CL–601 Variant), and CL–600–2B16 

(CL–601–3A and CL–601–3R Variants) 

airplanes. The NPRM published in the 

Federal Register on July 17, 2017 (82 FR 

32652) (‘‘the NPRM’’). The NPRM was 

prompted by a report of laminated 

shims that may have been improperly 

installed at a certain wing tie beam. The 

NPRM proposed to require revising the 

maintenance or inspection program to 

incorporate certification maintenance 

requirement tasks that introduce revised 

checks of the tie beam. We are issuing 

this AD to detect and correct 

degradation of the structural integrity of 

the affected tie beam, which could 

result in cracking of the pressure floor. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2016–34, 

dated October 14, 2016 (referred to after 


ethrower on DSK3G9T082PROD with RULES
Federal Register / Vol. 82, No. 195 / Wednesday, October 11, 2017 / Rules and Regulations 47095 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc., Model CL– 

600–1A11 (CL–600), CL–600–2A12 (CL– 

601 Variant), and CL–600–2B16 (CL– 

601–3A and CL–601–3R Variants) 

airplanes. The MCAI states: 

Bombardier has determined that laminated 

shims may have been improperly installed at 

the floor/wing tie beam bumper pads. 

Improperly installed shims may become 

damaged, which could result in a gapping 

condition. This would lead to increased 

stress and degradation of structural integrity 

of the tie beam. Undetected failure may lead 

to premature cracking of the pressure floor. 

Bombardier has introduced revised 

maintenance tasks through revisions of the 

applicable CL–600 Time Limits Maintenance 

Checks (TLMCs) to confirm structural 

integrity of the affected tie beam. 

This [Canadian] AD is issued to mandate 

the incorporation of the applicable revised 

TLMC tasks. 

You may examine the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

0691. 

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 (i)(1) 

of this AD. The request should include 

a description of changes to the required 

actions that will ensure the continued 

operational safety of the airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this 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 for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM.

following service information. 

• Task 53–10–00–131, ‘‘Pressure

This service information identifies 

airworthiness limitation tasks for checks 

of the pressure floor at a certain wing tie 

beam. These documents are distinct 

since they apply to different airplane 

models. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

Costs of Compliance 

We estimate that this AD affects 137 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

product 

Cost on U.S. 

operators 

Maintenance or inspection program revision .. 1 work-hour × $85 per hour = $85 ................. $0 $85 $11,645 

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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to transport category 

airplanes to the Director of the System 

Oversight Division. 

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.
