Federal Register / Vol. 86, No. 162 / Wednesday, August 25, 2021 / Proposed Rules Regulatory Findings The FAA 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, 2 Would not affect intrastate aviation in Alaska, and 3 Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

e Unsafe Condition This AD was prompted by the manufacturer revising the engine Time Limits Manual life limits of certain critical rotating parts and direct accumulation counting data files. The FAA is issuing this AD to prevent the failure of critical rotating parts. The unsafe condition, if not addressed, could result in failure of one or more engines, loss of thrust control, and loss of the airplane.

List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

h Exceptions to EASA AD 20200243
1 The requirements specified in paragraphs 1 and 2 of EASA AD 2020

3 Paragraph 3 of EASA AD 20200243
specifies revising the approved aircraft maintenance program AMP within 12
months after its effective date, but this AD
requires revising the existing approved AMP
within 90 days after the effective date of this AD.
4 This AD does not mandate compliance with the Remarks section of EASA AD
20200243.

Airworthiness Directives; Airbus Canada Limited Partnership Type Certificate Previously Held by C Series Aircraft Limited Partnership CSALP;
Bombardier, Inc. Airplanes Federal Aviation Administration FAA, DOT.
ACTION: Proposed rule; withdrawal.
AGENCY:

The FAA is withdrawing a notice of proposed rulemaking NPRM
that proposed to adopt a new airworthiness directive AD that would have applied to certain Airbus Canada Limited Partnership Model BD500
1A10 airplanes. The NPRM would have required an inspection of the lowpressure distribution supply duct to determine the part number, and replacement if necessary, as specified in a Transport Canada Civil Aviation TCCA AD. Since issuance of the NPRM, the FAA has determined that the affected operator has already addressed the unsafe condition by incorporating the proposed required actions on the affected airplanes. Accordingly, the NPRM is withdrawn.
DATES: As of August 25, 2021, the proposed rule, which was published in SUMMARY:
