Federal Register / Vol. 86, No. 162 / Wednesday, August 25, 2021 / Proposed Rules 47419 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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

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:

airworthiness directive (AD) by October 12, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Rolls-Royce 

Deutschland Ltd. & Co KG (Type Certificate 

previously held by Rolls-Royce plc) Trent 

1000–AE3, Trent 1000–CE3, Trent 1000–D3, 

Trent 1000–G3, Trent 1000–H3, Trent 1000–

(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. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Except as specified in paragraph (h) of this 

AD: Perform all required actions within the 

compliance times specified in, and in 

accordance with, European Union Aviation 

Safety Agency AD 2020–0243, dated 

November 5, 2020 (EASA AD 2020–0243). 

(h) Exceptions to EASA AD 2020–0243

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. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, ECO Branch, FAA, has 

the authority to approve AMOCs for this AD, 

if requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or local Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the certification office, 

send it to the attention of the person 

identified in paragraph (j)(2) of this AD. 

Information may be emailed to: ANE-ADAMOC@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

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 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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
47420 Federal Register / Vol. 86, No. 162 / Wednesday, August 25, 2021 / Proposed Rules

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 lowpressure 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). 

List of Subjects in 14 CFR Part 39

safety, Incorporation by reference,

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus Helicopters Model 

AS332L2 and EC225LP helicopters. This 

proposed AD was prompted by a design 

deficiency. This proposed AD would 

require modifying the hoist control 

power supply, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference (IBR). The 

FAA is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by October 12, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

https://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: (202) 493–2251.
