center fuel tank was mislocated, 

resulting in an offset between the fitting 

assembly and the refuel/defuel tube 

assembly. This AD requires 

modification of the fuel pipe bracket 

assembly, including all related 

investigative actions and corrective 

actions, if necessary; and performing an 

operational test of the refuel and defuel 

system. The FAA is issuing this AD to 

address the unsafe condition on these 

products.

SUPPLEMENTARY INFORMATION:

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2020–37, dated October 9, 2020 (also 

referred to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Bombardier, Inc., Model BD– 

700–1A10 airplanes. You may examine 

the MCAI in the AD docket on the 

internet at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0030. 

The FAA 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 

BD–700–1A10 airplanes. The NPRM 

published in the Federal Register on 

February 24, 2021 (86 FR 11191). The 

NPRM was prompted by a report 

indicating that during installation, a fuel 

pipe bracket assembly on the 

intermediate rib in the center fuel tank 

was mislocated, resulting in an offset 

between the fitting assembly and the 

refuel/defuel tube assembly. The NPRM 

proposed to require modification of the 

fuel pipe bracket assembly, including all 

related investigative actions and 

corrective actions, if necessary; and 

performing an operational test of the 

refuel and defuel system. The FAA is 

issuing this AD to address the offset, 

which could cause a preload on the fuel 

pipes and reduce their ability to absorb 

shock or vibration-induced loads, 

making the tube and clamp more prone 

to stress corrosion cracking. This could 

lead to failure of the coupling and the 

bracket and p-clamp assembly, resulting 

in fuel leakage and loss of electrical 

bonding between fuel pipes, and 

lightning-induced sparking that could 

induce fuel ignition. See the MCAI for 

additional background information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. The FAA has 

determined that these minor changes: 

• Are consistent with the intent that

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued Service 

Bulletin 700–28–6006, dated June 1, 

2020. This service information describes 

procedures for a modification of the fuel 

pipe bracket assembly, including 

investigative actions (a detailed visual 

inspection of the fuel pipe assembly for 

any damaged paint, permanent 

deformation, corrosion, cracking, 

gouges, dents, or deep scratches); 

installation of certain new parts; 

replacement of the fuel pipe and fuel 

pipe bracket assembly, if necessary; and 

an operational test of the refuel and 

defuel system. 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 

The FAA estimates that this AD 

affects 51 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

10 work-hours × $85 per hour = $850 ........................................................................................ $904 $1,754 $89,454 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

3 work-hours × $85 per hour = $255 ...................................................................................................................... $1,937 $2,192

According to the manufacturer, some 

or all of the costs of this AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

known costs in the cost estimate.

29180 Federal Register / Vol. 86, No. 103 / Tuesday, June 1, 2021 / Rules and Regulations 

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. 

The FAA is 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 

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) Will not affect intrastate aviation 

in Alaska, and 

(3) 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.

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 adding 

the following new airworthiness 

directive: 

2021–10–22 Bombardier, Inc.: Amendment 

39–21555; Docket No. FAA–2021–0030; 

Project Identifier MCAI–2020–01395–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective July 6, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bombardier, Inc., 

Model BD–700–1A10 airplanes, certificated 

in any category, serial numbers 9657 through 

9844 inclusive. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 28, Fuel. 

(e) Reason 

This AD was prompted by a report 

indicating that during installation, a fuel pipe 

bracket assembly on the intermediate rib in

issuing this AD to address the offset, which 

could cause a preload on the fuel pipes and 

reduce their ability to absorb shock or 

vibration-induced loads, making the tube and 

clamp more prone to stress corrosion 

cracking. This could lead to failure of the 

coupling and the bracket and p-clamp 

assembly, resulting in fuel leakage and loss 

of electrical bonding between fuel pipes, and 

lightning-induced sparking that could induce 

fuel ignition. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection and Corrective Action 

Within 30 months after the effective date
