AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–21– 

06, which applied to certain Airbus SAS 

Model A350–941 and –1041 airplanes. 

AD 2020–21–06 required revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. Since the FAA issued AD 

2020–21–06, the FAA has determined 

that new or more restrictive 

airworthiness limitations are necessary. 

This AD retains the requirements of AD 

2020–21–06 and requires revising the 

applicability by adding airplanes. This 

AD also requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, 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 June 16, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of June 16, 2022. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0206, 

dated September 15, 2021 (EASA AD 

2021–0206) (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. 

Airplanes with an original airworthiness 

certificate or original export certificate 

of airworthiness issued after June 30, 

2021, must comply with the 

airworthiness limitations specified as 

part of the approved type design and 

referenced on the type certificate data 

sheet; this AD therefore does not 

include those airplanes in the 

applicability. EASA AD 2021–0206 

supersedes EASA AD 2020–0091, dated 

April 22, 2020 (EASA AD 2020–0091). 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–21–06, 

Amendment 39–21279 (85 FR 64961, 

October 14, 2020) (AD 2020–21–06). AD 

2020–21–06 applied to certain Airbus 

SAS Model A350–941 and –1041 

airplanes. The NPRM published in the 

Federal Register on February 7, 2022 

(87 FR 6798). The NPRM was prompted 

by a determination that new or more 

restrictive airworthiness limitations are 

necessary. The NPRM proposed to 

continue to require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in EASA AD 2020–0091. The 

NPRM also proposed to require revising 

the existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations, as specified in EASA AD 

2021–0206. The NPRM also proposed to 

revise the applicability by adding 

airplanes. Accomplishing the new 

maintenance or inspection program 

revision specified in paragraph (j) of this 

AD terminates the retained maintenance 

or inspection program revision specified 

in paragraph (g) of this AD. 

The FAA is issuing this AD to address 

the potential failure of certain lifelimited parts, which could result in 

reduced structural integrity of the 

airplane. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

Air Line Pilots Association, 

International (ALPA), who supported 

the NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety requires 

adopting this AD as proposed. 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. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0206 describes new 

or more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires EASA AD 

2020–0091, dated April 22, 2020, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of November 18, 2020 (85 FR 64961, 

October 14, 2020). 

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 24 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2020–21–06 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2017–14– 

13, which applied to certain The Boeing 

Company Model 737–600, –700, –700C, 

–800, –900, and –900ER series 

airplanes. AD 2017–14–13 required a 

torque check of the screws in the cover 

assembly of the heel rest for both the 

captain’s and the first officer’s rudder 

pedals, and corrective action if 

necessary. This AD was prompted by a 

report of an aborted takeoff because the 

rudder pedals were not operating 

correctly, and subsequent reports of 

loose rudder pedal cover fasteners on 

airplanes on which the actions required 

by AD 2017–14–13 were done and on 

additional airplanes that were not 

included in the applicability of AD 

2017–14–13. This AD requires 

modifying the rudder pedal cover and 

shroud assemblies, and applies to all 

The Boeing Company Model 737–600, 

–700, –700C, –800, –900, and –900ER 

series airplanes and Model 737–8 and 

737–9 airplanes. This AD also limits the 

installation of affected parts under 

certain conditions. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective June 16, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 16, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2017–14–13, 

Amendment 39–18957 (82 FR 33007, 

July 19, 2017) (‘‘AD 2017–14–13’’). AD 

2017–14–13 applied to certain The 

Boeing Company Model 737–600, –700, 

–700C, –800, –900, and –900ER series 

airplanes. AD 2017–14–13 required a 

torque check of the screws in the cover 

assembly of the heel rest for both the 

captain’s and the first officer’s rudder 

pedals, and corrective action if 

necessary. 

The NPRM published in the Federal 

Register on January 21, 2021 (86 FR 

6273). The NPRM was prompted by a 

report of an aborted takeoff because the 

rudder pedals were not operating 

correctly and subsequent reports of 

loose rudder pedal cover fasteners on 

airplanes on which the actions required 

by AD 2017–14–13 had been done. 

These reports demonstrated that the 

required torque checks were ineffective 

in guaranteeing fastener retention and 

that additional airplanes that had not 

been included in the applicability of AD 

2017–14–13 are also affected (i.e., all 

Model 737–8 and 737–9 airplanes; and 

Model 737–600, –700, –700C, –800, 

–900, and –900ER series airplanes, 

having line numbers 3556 and 

subsequent). In the NPRM, the FAA 

proposed to require modifying the 

rudder pedal cover and shroud 

assemblies with a new design that 

prevents the fasteners from backing out. 

The NPRM also proposed to limit the 

installation of affected parts under 

certain conditions, including 

modification of the cover or shroud 

assembly in accordance with the 

requirements of paragraph (h) of this 

AD. The FAA is issuing this AD to 

address cover assembly fasteners 

interfering with the operation of a 

rudder pedal. A fastener can back out 

and restrict rudder pedal motion and 

reduce differential braking control 

during takeoff or landing, which could 

cause a high-speed runway excursion. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received supportive 

comments from two commenters: Air 

Line Pilots Association, International 

(ALPA) and United Airlines (UAL). 

ALPA supported the NPRM without 

change. UAL supported the NPRM, but 

requested clarification regarding the 

method for part marking, as discussed 

later in this discussion. 

The FAA also received comments 

from Boeing, Aviation Partners Boeing, 

and Delta Air Lines (DAL). The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

the installation of winglets per 

Supplemental Type Certificate STC 

ST00830SE does not affect compliance 

with the proposed actions. 

The FAA agrees with the commenter. 

The installation of STC ST00830SE does 

not affect an operator’s ability to 

accomplish the actions required by this 

AD. The FAA has not changed this AD.
