AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus SAS Model A350–941 and –1041 

airplanes. This proposed AD was 

prompted by reports of slat transmission 

jams caused by frozen slat geared rotary 

actuators (SGRA) at slat 5 track 12. This 

proposed AD would require repetitive 

water drainage and plug cleaning of the 

left- and right-hand SGRA having a 

certain part number installed on slat 5 

track 12 with certain functional item 

numbers, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference. 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 November 8, 

2021.

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021– 

0130R1, dated June 10, 2021 (EASA AD 

2021–0130R1) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Airbus SAS 

Model A350–941 and –1041 airplanes. 

This proposed AD was prompted by 

reports of slat transmission jams caused 

by frozen SGRA at slat 5 track 12. 

Further investigation showed that the 

jams occur when water in the SGRA 

freezes due to low temperature during 

cruise and insufficient water drainage. 

The FAA is proposing this AD to 

address SGRA jams, which could result 

in reduced control of the airplane. See 

the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0130R1 describes 

procedures for repetitive water drainage 

and plug cleaning of the left- and righthand SGRA having part number 

4775A0000–02 installed on slat 5 track 

12 with functional item number (FIN) 

5045CW and FIN 5145CW (including 

reinstalling incorrectly installed drain 

plug assemblies and replacing any 

damaged or missing nylon pins). This 

material is reasonably available because 

the interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is proposing this AD 

because the FAA evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2021–0130R1 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate EASA AD 2021–0130R1 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021– 

0130R1 in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2021–0130R1 does not mean 

that operators need comply only with 

that section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2021–0130R1. 

Service information required by EASA 

AD 2021–0130R1 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0827 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 15 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD:

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s 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 Agency’s 

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 

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,

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 Deutschland 

GmbH Model EC135P2+, EC135P3, 

EC135T2+, and EC135T3 helicopters. 

This proposed AD was prompted by 

reports that certain aft and forward 

fitting assemblies, which are not 

approved for installation on certain 

helicopters, were installed on those 

helicopters as part of the outboard load 

system. Operators of those helicopters 

might not be aware of the applicable 

overhaul or life limits for those fitting 

assemblies. This proposed AD would 

require inspecting the aft and forward 

fitting assemblies of the outboard load 

system to determine the part number, 

re-identifying the part if necessary, 

inspecting each affected part for damage 

(which may be indicated by signs of 

corrosion, mechanical damage, loose 

rivets, or cracks) and, depending on the 

findings, corrective actions, 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 November 8, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

all comments received by the closing 

date and may amend this proposal 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Darren Gassetto, 

Aerospace Engineer, COS Program 

Management Section, Operational 

Safety Branch, Compliance & 

Airworthiness Division, FAA, 1600 

Stewart Ave., Suite 410, Westbury, NY 

11590; telephone (516) 228–7323; email 

Darren.Gassetto@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking.
