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 FAAs 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 Agencys 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.

VerDate Sep<11>2014

Jkt 253001

20211022 Bombardier, Inc.: Amendment 3921555; Docket No. FAA20210030;
Project Identifier MCAI202001395T.
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 BD7001A10 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 the center fuel tank was mislocated, resulting in an offset between the fitting assembly and the refuel/defuel tube assembly. 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.
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 of this AD: Perform a modification of the fuel pipe bracket assembly and refuel tube assembly; do all related investigative actions and applicable corrective actions; and perform an operational test of the refuel and defuel system; in accordance with paragraphs 2.B. and 2.C. of the Accomplishment Instructions of Bombardier Service Bulletin 700286006, dated June 1, 2020. All related investigative and corrective actions must be done before further flight.
