Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus SAS Model A350–941 and 

A350–1041 airplanes. This AD is 

prompted by reports that excessively 

deep spot faces on the front engine 

mounting bolt holes on the wing pylon 

were detected on the production line. 

This AD requires a one-time inspection 

for clash (interference) of the three front 

engine mounting bolt holes on both the 

left and right wing pylons, and, 

depending on findings, accomplishment 

of applicable corrective actions, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective November 9, 

2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 9, 2023.

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 certain Airbus SAS Model 

A350–941 and A350–1041 airplanes. 

The NPRM published in the Federal 

Register on June 1, 2023 (88 FR 35785). 

The NPRM was prompted by AD 2023– 

0026, dated January 30, 2023, issued by 

EASA (EASA AD 2023–0026) (also 

referred to as the MCAI), which is the 

Technical Agent for the Member States 

of the European Union. The MCAI states 

excessively deep spot faces have been 

detected on the production line on rib 

1 at the level of the front engine mount 

bolting. This could cause possible 

integration issues between the pylon 

and the front engine mount, which 

could lead to interference damage. This 

condition, if not detected and corrected, 

could lead to a reduced fatigue life, 

which could adversely affect the 

structural integrity of the airplane. 

In the NPRM, the FAA proposed to 

require a one-time inspection for clash 

(interference) of the three front engine 

mounting bolt holes on both the left and 

right wing pylons, and, depending on 

findings, accomplishment of applicable 

corrective actions, as specified in EASA 

AD 2023–0026. 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–2023–1056. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from Air 

Line Pilots Association, International 

(ALPA) who supported the NPRM 

without change. 

The FAA received additional 

comments from Delta Air Lines (Delta). 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request for Another Exception to the 

MCAI 

Delta requested an exception to 

require only accomplishment of Airbus 

Service Bulletin A350–71–P011, 

Revision 01, dated December 20, 2022 

(ASB A350–71–P011) and Airbus 

Service Bulletin A350–71–P015, dated 

December 20, 2022 (ASB A350–71– 

P015), ‘‘in accordance’’ with steps in 

those bulletins. Otherwise, the ‘‘in 

accordance with’’ in Airbus Service 

Bulletin A350–54–P006, Rev 01, dated 

December 20, 2022 (ASB A350–54– 

P006), and Airbus Service Bulletin 

A350–54–P008, dated December 20, 

2022 (ASB A350–54–P008) might 

otherwise be inferred as requiring the 

entire service bulletin, ASB A350–71– 

P011 or ASB A350–71–P015, as 

mandatory. 

Delta explained that ASB A350–54– 

P006 and ASB A350–54–P008 required 

to be accomplished by EASA AD 2023– 

0026, use the ‘‘in accordance with’’ 

language to call for implementation of 

ASB A350–71–P011, and ASB A350– 

71–P015 and states that ASB A350–71– 

P011 and ASB A350–71–P015 do not 

have the paragraph specifying 

‘‘Required for compliance’’ (RC) actions. 

Delta states this might infer the entire 

ASB A350–71–P011 or ASB A350–71– 

P015 must be accomplished for AD 

compliance. 

The FAA agrees to clarify. The FAA 

AD refers to EASA AD 2023–0026, 

which requires following the mandatory 

(required for compliance) actions in 

ASB A350–54–P006 and ASB A350–54– 

P008. These two service bulletins 

include RC actions that specify that 

specific actions must be done in 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 192 / Thursday, October 5, 2023 / Rules and Regulations 69009 

accordance with ASB A350–71–P011 

and ASB A350–71–P015. Additionally, 

ASB A350–71–P011 and ASB A350–71– 

P015, specify in a note within the 

accomplishment instructions that 

‘‘access and close-up instructions, not 

comprising return to service tests’’ can 

be omitted or amended to add flexibility 

to their maintenance operations as long 

as the technical intent is met. Therefore, 

the required actions in ASB A350–71– 

P011 and ASB A350–71–P015 are those 

that are not specified as access or closeup instructions, and are the actions 

specifically described by ASB A350–54– 

P006 and ASB A350–54–P008. As an 

example, ASB A350–54–P006 specifies 

to ‘‘Disassemble the retention bracket 

assy and the 3 pylon bolt assemblies 

during engine removal’’, for which the 

technical intent of the ASB A350–54– 

P006 is to comply with the instructions 

in ASB A350–71–P011 that include 

these actions. 

Request for Clarification if the Test 

Section in the Bulletins Are Required 

Delta requested clarification on 

whether the Test Section in ASB A350– 

54–P006, ASB A350–54–P008, ASB 

A350–71–P011, and ASB A350–71– 

P015 are required. The instructions do 

not use ‘‘in accordance with’’ or ‘‘refer 

to’’ language, leaving confusion. 

The ‘‘Test’’ sections of ASB A350–54– 

P006 and ASB A350–54–P008 require 

the accomplishment of tests given in 

other topics which are referenced in 

ASB A350–71–P011 or ASB A350–71– 

P015. The ‘‘Test’’ sections of ASB 

A350–71–P011 and ASB A350–71–P015 

state ‘‘Do the test procedure as specified 

in the installation of the demountable 

power plant (FIN 4000EM1 or 2), refer 

to MP A350–A–71–00–51–00ZZZ– 

720Z–A.’’ 

The FAA provides the following 

clarification. The tests specified in ASB 

A350–54–P006 and ASB A350–54–P008 

are required. The Required for 

Compliance section of the 

Accomplishment Instructions states that 

paragraph 3.E. are RC. Any mandatory 

language, such as accomplishment of 

tests, in 3.E. is therefore required. As 

described by the commenter, since the 

Test sections of ASB A350–54–P006 and 

ASB A350–54–P008 specify that the 

accomplishment of Tests given in other 

topics are also required, therefore the 

Test sections in ASB A350–71–P011 

and ASB A350–71–P015 are also 

required. The FAA has not changed this 

AD as a result of this comment. 

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 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

reviewed the relevant data, considered 

the comments received, 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. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0026 specifies 

procedures for a one-time inspection for 

clash of the three pylon bolt holes at rib 

1 (forward engine attachment on pylon), 

on both the left and right wing pylons, 

and applicable corrective actions. 

Corrective actions include installing the 

post-mod retention bracket assembly; 

accomplishing a detailed inspection and 

a high frequency eddy current (HFEC) 

inspection or a penetrant inspection on 

rib 1 for damage (cracks, scratches, or 

erosion of the protective coating); 

measuring the spot face depth and 

pylon thickness and obtaining and 

following instructions if incorrect spot 

face depth or pylon thickness at the spot 

face are found; and repair. 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: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

56 work-hours × $85 per hour = $4,760 ..................................................................................... $0 $4,760 $147,560 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

10 work-hours × $85 per hour = $850 .................................................................................................................... $10 $860 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition repairs specified in 

this 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 


ddrumheller on DSK120RN23PROD with RULES1
69010 Federal Register / Vol. 88, No. 192 / Thursday, October 5, 2023 / Rules and Regulations 

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.

of the protective coating); and incorrect spot 

face depth or pylon thickness at the spot face. 

(3) Where paragraph (2) of EASA AD 2023– 

0026 specifies to ‘‘contact Airbus for 

approved instructions for corrective action 

and accomplish those instructions 

accordingly’’ if discrepancies are detected; 

for this AD if any cracking is detected, the 

cracking must be repaired before further 

flight using a method approved 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. 

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

section of EASA AD 2023–0026. 

(5) Where the service information 

referenced in EASA AD 2023–0026 specifies 

to report inspection results or findings, this 

AD requires submitting information only if 

damage (cracks) or incorrect spot face depth 

or pylon thickness at the spot face are found 

during any inspection required by EASA AD 

2023–0026. Operators are required to submit 

certain information as part of obtaining any 

corrective actions approved by Airbus SAS’s 

EASA DOA. 

(i) Additional AD Provisions 

The following provisions also apply to this

requirement in this AD to obtain instructions 

from a manufacturer, the instructions must 

be accomplished using a method approved 

by the Manager, International Validation 

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

EASA DOA. If approved by the DOA, the 

approval must include the DOA-authorized 

signature. 

(3) Required for Compliance (RC): Except 

as required by paragraph (i)(2) of this AD, if 

any service information contains procedures 

or tests that are identified as RC, those 

procedures and tests must be done to comply 

with this AD; any procedures or tests that are 

not identified as RC are recommended. Those 

procedures and tests that are not identified 

as RC may be deviated from using accepted 

methods in accordance with the operator’s 

maintenance or inspection program without 

obtaining approval of an AMOC, provided 

the procedures and tests identified as RC can

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2021–10– 

20, which applied to certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR42–500 and ATR72–212A 

airplanes. AD 2021–10–20 required 

revising the existing aircraft flight 

manual (AFM) and applicable 

corresponding operational procedures to 

update a systems limitation, limiting 

dispatch with certain equipment 

inoperative, performing an operational 

test of a certain contactor and an 

electrical test of a certain battery toggle 

switch, and performing corrective 

actions if necessary. This AD was 

prompted by new procedures for 

modifying the wiring and replacing the 

battery toggle switch that have been 

developed that would terminate the AD 

requirements. This AD continues to 

require certain actions in AD 2021–10– 

20, and requires modifying the battery 

toggle switch wiring and replacing the 

battery toggle switch, and revises the 

applicability to include additional 

airplanes, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

This AD also prohibits the installation 

of affected parts. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective November 9, 

2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2021–10–20, 

Amendment 39–21553 (86 FR 26373, 

May 14, 2021) (AD 2021–10–20). AD 

2021–10–20 applied to certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR42–500 and ATR72–212A 

airplanes. AD 2021–10–20 required 

revising the existing AFM and 

applicable corresponding operational 

procedures to update a systems 

limitation, limiting dispatch with 

certain equipment inoperative, 

performing an operational test of a 

certain contactor and an electrical test of 

a certain battery toggle switch, and 

performing corrective actions if 

necessary. The FAA issued AD 2021– 

10–20 to address reports of temporary 

loss of all display units and the 

integrated electronic standby instrument 

(IESI), which could result in loss of 

control of the airplane. 

The NPRM published in the Federal 

Register on July 28, 2023 (88 FR 48764). 

The NPRM was prompted by AD 2023– 

0078R1, dated April 20, 2023, issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union (EASA AD 2023–0078R1) (also 

referred to as the MCAI). The MCAI 

states that new modification 

instructions have been published that 

would terminate the requirements of 

EASA Emergency AD 2021–0120–E, 

dated May 3, 2021 (which prompted 

FAA AD 2021–10–20). The MCAI also 

expands the applicability to include 

Model ATR72–101, –102, –201, –202, 

–211, and –212 airplanes. The MCAI 

states that temporary loss of all display 

units and the IESI, if not corrected, 

could result in loss of control of the 

airplane. 

In the NPRM, the FAA proposed to 

continue to require certain actions in 

AD 2021–10–20, and to require 

modifying the battery toggle switch 

wiring and replacing the battery toggle 

switch, and to revise the applicability to 

include additional airplanes, as 

specified in EASA AD 2023–0078R1. 

The NPRM also proposed to prohibit the 

installation of affected parts. 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–2023–1641. 

Changes Since the NPRM Was Issued 

In the ‘‘Costs of Compliance’’ section, 

the NPRM stated an incorrect estimated 

cost of the retained actions from AD 

2021–10–20. The FAA has corrected the 

cost information in this final rule. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received one comment from 

Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

Conclusion 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in the MCAI referenced 

above. The FAA reviewed the relevant 

data, considered the comment received, 

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, and any other changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator.
