Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2017–31, dated September 22, 2017 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Bombardier, Inc., 

Model BD–700–1A10 and BD–700– 

1A11 airplanes. The MCAI states: 

There have been multiple in-service 

occurrences where operators reported inflight departure of the aft belly fairing access 

panels, 185CL and/or 186CR. There has been 

no damage reported to the affected aircraft to 

date, however departure of the panels in any 

phase of flight could create runway hazards 

or a hazard to persons and property on the 

ground. 

Bombardier Inc. has issued Service 

Bulletins (SBs) to incorporate new 

self¥locking nutplates with associated 

hardware (retaining rings and studs) to 

improve fastener engagement. A bracket has 

also been added to provide two additional 

panel attachment points. 

This [Canadian] AD requires the 

incorporation of these design changes to 

prevent departure of the two aft belly fairing 

access panels in flight and the associated risk 

on the ground. 

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–2018– 

0546. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued the following 

service information: 

• Service Bulletin 700–1A11–53–025, 

Revision 01, dated December 16, 2016; 

• Service Bulletin 700–53–050, 

Revision 01, dated December 16, 2016; 

• Service Bulletin 700–53–5009, 

Revision 01, dated December 16, 2016; 

and 

• Service Bulletin 700–53–6008, 

Revision 01, dated December 16, 2016. 

The service information describes 

actions to modify the aft belly fairing 

access panels by replacing the 

attachments. These documents are 

distinct since they apply to different 

airplane models in different 

configurations. 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. 

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. 

Costs of Compliance 

We estimate that this proposed AD 

affects 110 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

4 work-hours × $85 per hour = $340 .......................................................................................... $2,640 $2,980 $327,800 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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 proposed 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 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; 


sradovich on DSK3GMQ082PROD with PROPOSALS
Federal Register / Vol. 83, No. 119 / Wednesday, June 20, 2018 / Proposed Rules 28555 

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.

safety, Incorporation by reference,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A318 series; Model A319 

series; Model A320 series; and Model 

A321–111, –112, –131, –211, –212,
