Download as PDF 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 2020–0243 (1) The requirements specified in paragraphs (1) and (2) of EASA AD 2020– 0243 are not required by this AD. (2) Where EASA AD 2020–0243 requires compliance from its effective date, this AD requires using the effective date of this AD. (3) Paragraph (3) of EASA AD 2020–0243 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 2020–0243. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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: ■ Rolls-Royce Deutschland Ltd & Co KG (Type Certificate previously held by RollsRoyce plc): Docket No. FAA–2021–0690; Project Identifier MCAI–2020–01495–E.

ACTION: Proposed rule; withdrawal.

-----------------------------------------------------------------------

SUMMARY: 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 BD-500-
1A10 airplanes. The NPRM would have required an inspection of the low-
pressure 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

[[Page 47420]]

the Federal Register on April 16, 2021 (86 FR 20091), is withdrawn.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued an NPRM that proposed to amend 14 CFR part 39 by 
adding an AD that would apply to certain Airbus Canada Limited 
Partnership Model BD-500-1A10 airplanes. The NPRM was published in the 
Federal Register on April 16, 2021 (86 FR 20091). The NPRM was prompted 
by a report that an incorrect low-pressure distribution supply duct may 
be installed in the forward cargo compartment. The NPRM proposed to 
require an inspection of the low-pressure distribution supply duct to 
determine the part number, and replacement if necessary, as specified 
in a Transport Canada Civil Aviation (TCCA) AD.

Actions Since the NPRM Was Issued

    Since issuance of the NPRM, the FAA has verified that the proposed 
actions have been done on the affected airplanes. Therefore, the FAA 
has determined that AD action is not appropriate.
    Withdrawal of the NPRM constitutes only such action and does not 
preclude the FAA from further rulemaking on this issue, nor does it 
commit the FAA to any course of action in the future.

Comments

Support for the NPRM

    The Air Line Pilots Association, International (ALPA) expressed 
support for the NPRM.

Request To Not Issue the Proposed AD

    Delta Air Lines (Delta) requested that the proposed AD not be 
issued. DAL stated that replacement of the affected part as required by 
the proposed AD had already been done on both of the affected 
airplanes. Alternatively, Delta requested that the FAA allow use of the 
high-pressure ground connection as an alternative to the auxiliary 
power units because Delta's affected airplanes had been preserved in 
storage and could not be started if necessary to perform a required 
leak check. The FAA agrees with the commenter's requests, but because 
the FAA is withdrawing the NPRM, Delta's alternative request is no 
longer necessary.

FAA's Conclusions

    Upon further consideration, the FAA has determined that the NPRM is 
unnecessary. Accordingly, the NPRM is withdrawn.

Regulatory Findings

    Since this action only withdraws an NPRM, it is neither a proposed 
nor a final rule. This action therefore is not covered under Executive 
Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979).

The Withdrawal

    Accordingly, the notice of proposed rulemaking (Docket No. FAA-
2021-0298), which was published in the Federal Register on April 16, 
2021 (86 FR 20091), is withdrawn.
