Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus SAS Model A350–941 and –1041 

airplanes. This AD was prompted by 

reports that engine nacelle anti-icing 

(NAI) forward bulkheads have been 

found with elongated locating holes. 

This AD requires a one-time detailed 

inspection of the engine NAI forward 

bulkhead locating holes for elongation 

and loose fasteners and applicable 

corrective actions, and prohibits the 

installation of affected parts under 

certain conditions, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference (IBR). The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective November 

29, 2024.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus SAS Model A350– 

941 and –1041 airplanes. The NPRM 

published in the Federal Register on 

July 3, 2024 (89 FR 55120). The NPRM 

was prompted by AD 2024–0060R1, 

dated April 16, 2024, issued by EASA, 

which is the Technical Agent for the 

Member States of the European Union 

(EASA AD 2024–0060R1) (also referred 

to as the MCAI). The MCAI states that 

certain engine NAI forward bulkheads 

may have elongated locating holes. 

These holes are used in the 

manufacturing process and closed with 

fasteners before delivery. It has been 

determined that these fasteners, if loose, 

may vibrate and cause further 

elongation of the locating holes, which, 

eventually, can reduce the NAI 

performance. This condition, if not 

detected and corrected, could lead to 

the undetected loss of NAI protection on 

both engines, possibly resulting in loss 

of control of the airplane. 

In the NPRM, the FAA proposed to 

require a one-time detailed inspection of 

the engine NAI forward bulkhead 

locating holes for elongation and loose 

fasteners and applicable corrective 

actions, and prohibit the installation of 

affected parts under certain conditions, 

as specified in EASA AD 2024–0060R1. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1881. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

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 this State of 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 89, No. 206 / Thursday, October 24, 2024 / Rules and Regulations 84807 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

reviewed the relevant data and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on this 

product. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0060R1 specifies 

procedures for a one-time detailed 

inspection of the engine NAI forward 

bulkhead location holes for 

discrepancies, including elongation and 

loose fasteners. Depending on the 

inspection results, EASA AD 2024– 

0060R1 also specifies corrective action, 

including obtaining and following 

instructions if any discrepancy is 

identified. EASA AD 2024–0060R1 also 

requires reporting of the inspection 

results to Collins Aerospace. EASA AD 

2024–0060R1 also prohibits the 

installation of an affected part on any 

airplane unless it is a serviceable part 

and is inspected before installation. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 31 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

7.5 work-hour × $85 per hour = $638 ................................................................................................. $10 $648 $20,088 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition repairs specified in 

this AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected operators. 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will 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 Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2024–19–04 Airbus SAS Airplanes: 

Amendment 39–22846; Docket No. 

FAA–2024–1881; Project Identifier 

MCAI–2024–00160–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective November 29, 2024. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Airbus SAS Model 

A350–941 and –1041 airplanes, certificated 

in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 54, Nacelles/pylons. 

(e) Unsafe Condition 

This AD was prompted by reports that 

engine nacelle anti-icing (NAI) forward 

bulkheads may have elongated locating 

holes. The FAA is issuing this AD to address 

elongated locating holes. The unsafe 

condition, if not addressed, could result in 

the fasteners, if loose, to vibrate and cause 

further elongation of the locating holes, 

which, eventually, can reduce the NAI 

performance. This condition, if not detected 

and corrected, could lead to the undetected 

loss of NAI protection on both engines, 

possibly resulting in loss of control of the 

airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraphs (h) and 

(i) of this AD: Comply with all required 

actions and compliance times specified in, 

and in accordance with, European Union 

Aviation Safety Agency (EASA) AD 2024– 

0060R1, dated April 16, 2024 (EASA AD 

2024–0060R1). 

(h) Exceptions to EASA AD 2024–0060R1 

(1) Where EASA AD 2024–0060R1 refers to 

its effective date, this AD requires using the 

effective date of this AD. 

(2) Where paragraph (2) of EASA AD 2024– 

0060R1 specifies if ‘‘any discrepancy is 

detected, before next flight, contact Collins 

Aerospace for approved corrective action 

instructions and, within the compliance time 

specified therein accomplish those 

instructions accordingly,’’ this AD requires 

replacing that text with if ‘‘any discrepancy 

is detected, the discrepancy must be repaired 


lotter on DSK11XQN23PROD with RULES1
84808 Federal Register / Vol. 89, No. 206 / Thursday, October 24, 2024 / Rules and Regulations

by the Manager, International Validation 

Branch, FAA; or EASA; or Airbus SAS’s 

EASA Design Organization Approval (DOA). 

If approved by the DOA, the approval must 

include the DOA-authorized signature.’’ 

(3) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2024–0060R1. 

(i) No Reporting Required 

Although EASA AD 2024–0060R1 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Additional AD Provisions

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to Robinson Helicopter Model 

R22 Beta, R22 Mariner, R44, and R44 II

part number (P/N) D270–1, Revision A 

through E inclusive, installed. The 

NPRM published in the Federal 

Register on July 17, 2024 (89 FR 58084). 

The NPRM was prompted by three 

reports of governor controller failures 

involving Robinson Helicopter Model 

R22 Beta and R44 II helicopters. Prior to 

these governor controller failures, 

several operators notified Robinson 

Helicopter of a malfunction of the 

governor controller. As a result of an 

investigation, it has been determined
