Federal Register / Vol. 86, No. 154 / Friday, August 13, 2021 / Rules and Regulations 39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

20211707 Airbus Canada Limited Partnership Type Certificate Previously Held by C Series Aircraft Limited Partnership CSALP; Bombardier, Inc.:
Amendment 3921690; Docket No.
FAA20210669; Project Identifier MCAI202100314T.
a Effective Date This airworthiness directive AD becomes effective August 30, 2021.
b Affected ADs None.
c Applicability This AD applies to Airbus Canada Limited Partnership type certificate previously held by C Series Aircraft Limited Partnership CSALP; Bombardier, Inc. Model BD500
1A10 and BD5001A11 airplanes, certificated in any category, as identified in Transport Canada Civil Aviation TCCA AD
CF202109, dated March 11, 2021 TCCA
AD CF202109.
d Subject Air Transport Association ATA of America Code 28, Aircraft fuel system.
e Reason This AD was prompted by the potential for the flexible hose assembly of the fuel motive flow MF, installed between the pylon and wing, to be installed twisted in the shroud, which can restrict the flow of fuel for the MF
and cause fuel imbalance and possible damage, including abrasion, to the shroud assembly. The FAA is issuing this AD to address this condition, which could result in abrasion of the fuel line and a possible fuel leak; as a result, the electrical harness connectors in the wing area could be a potential ignition source and pose a risk of fire.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Requirements Except as specified in paragraph h of this AD: Comply with all required actions and compliance times specified in, and in accordance with, TCCA AD CF202109.

h Exception to TCCA AD CF202109
1 Where TCCA AD CF202109 refers to its effective date, this AD requires using the effective date of this AD.
2 Where TCCA AD CF202109 specifies replacing MF fuel line assemblies, this AD
requires that replacement before further flight after any damage including any permanent deformity is detected.
i No Return of Parts Although the service information referenced in TCCA AD CF202109
specifies to return certain parts to the manufacturer, this AD does not include that requirement.

Docket No. FAA20190111; Airspace Docket No. 19ASO23
RIN 2120AA66

Establishment of Restricted Area R
5306F; Cherry Point, NC
Federal Aviation Administration FAA, Department of Transportation DOT.
ACTION: Final rule.
AGENCY:

SUMMARY: This action establishes restricted area R5306F at Marine Corps Air Station MCAS Cherry Point, NC.
R5306F extends from flight level FL
180 to FL 290. Restricted area R5306F
overlie the existing restricted area R
5306A, and the adjacent Core Military Operations Area MOA. Due to altitude constraints, the existing restricted airspace structure around MCAS Cherry Point cannot fully support the training requirements for current legacy aircraft as well as 4th and 5th generation aircraft such as the F35. In conjunction with R5306A, restricted area R5306F will allow for realistic training to enable pilots and aircrews to counter evolving threat nation warfare anti-aircraft capabilities.
DATES: Effective date 0910 UTC, December 2, 2021.
