Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2019–03–10, which applies to all Airbus 

SAS Model A300 series airplanes; and 

Model A300 B4–600, B4–600R, and F4– 

600R series airplanes, and Model A300 

C4–605R Variant F airplanes 

(collectively called Model A300–600 

series airplanes). AD 2019–03–10 

requires repetitive detailed visual 

inspections of the main landing gear 

(MLG) leg components and replacement 

of the MLG leg if cracked components 

are found. Since the FAA issued AD 

2019–03–10, it was determined that 

additional actions (including 

inspections, modifications, and checks) 

are needed to address the unsafe 

condition. This proposed AD would 

continue to require the actions required 

by AD 2019–03–10. For certain 

airplanes, this proposed AD would also 

require modification of the MLG hinge 

arm by installing improved MLG hinge 

arm/barrel pins; an out-of-roundness 

check of removed pins; repetitive 

inspections of any affected pins and the 

associated connecting rod bushes, and 

replacement of the MLG leg if cracked 

components are found; and installation 

of an improved spacer 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 January 22, 

2021. 

ADDRESSES: You may send comments,

Discussion 

The FAA issued AD 2019–03–10, 

Amendment 39–19562 (84 FR 5595, 

February 22, 2019) (AD 2019–03–10), 

which applies to all Airbus SAS Model 

A300 series airplanes; and Model A300– 

600 series airplanes. AD 2019–03–10 


jbell on DSKJLSW7X2PROD with PROPOSALS
78972 Federal Register / Vol. 85, No. 236 / Tuesday, December 8, 2020 / Proposed Rules 

requires repetitive detailed visual 

inspections of the MLG leg components 

and replacement of the MLG leg if 

cracked components are found. The 

FAA issued AD 2019–03–10 to address 

cracking of certain components in the 

MLG leg, which could result in an MLG 

collapse, and consequent damage to the 

airplane and injury to the airplane 

occupants. 

Actions Since AD 2019–03–10 Was 

Issued 

Since the FAA issued AD 2019–03– 

10, Airbus issued instructions for 

installation of a new MLG hinge arm/ 

barrel pin with wet primer integration, 

to improve corrosion protection. It was 

also determined that an out-ofroundness check of removed pins is 

needed to detect potential overload. 

Airbus also issued instructions for 

repetitive general visual inspections of 

affected pins and connecting rod 

bushes. Airbus also issued instructions 

for modification of the spacer design to 

prevent migration of the connecting rod 

bushes in case of bush fracture. 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0145, dated July 1, 2020 (EASA 

AD 2020–0145) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Airbus SAS 

Model A300 series airplanes; Model 

A300–600 series airplanes; and Model 

A300F4–608ST airplanes. EASA AD 

2020–0145 supersedes EASA AD 2018– 

0170 (which corresponds to FAA AD 

2019–03–10). Model A300F4–608ST 

airplanes are not certificated by the FAA 

and are not included on the U.S. type 

certificate data sheet; this proposed AD 

therefore does not include those 

airplanes in the applicability. 

This proposed AD was prompted by 

reports of cracks in MLG leg 

components, and a determination that 

additional actions (including 

inspections, modifications, and checks) 

are needed to address the unsafe 

condition. The FAA is proposing this 

AD to address cracking of certain 

components in the MLG leg, which 

could result in an MLG collapse, and 

consequent damage to the airplane and 

injury to the airplane occupants. See the 

MCAI for additional background 

information. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2019–03–10, this proposed AD would 

retain all of the requirements of AD 

2019–03–10. Those requirements are 

referenced in EASA AD 2020–0145, 

which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0145 describes 

procedures for repetitive detailed visual 

inspections of the MLG leg components 

and replacement of the MLG leg if 

cracked components are found. EASA 

AD 2020–0145 also describes 

procedures, for certain airplanes, for 

modification of the MLG hinge arm by 

installing improved pins, which would 

terminate the repetitive detailed 

inspections required by AD 2019–03– 

10; an out-of-roundness check of 

removed pins; repetitive inspections of 

affected pins and the associated 

connecting rod bushes for cracking, and 

replacement of the MLG leg if cracked 

components are found; and installation 

of an improved spacer, which would 

terminate the repetitive pin and rod 

bushes inspections. EASA AD 2020– 

0145 also describes procedures for 

reporting results of the out-of-roundness 

check to Safran. 

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 pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2020–0145 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 initially worked with 

Airbus and EASA to develop a process 

to use certain EASA ADs as the primary 

source of information for compliance 

with requirements for corresponding 

FAA ADs. The FAA has since 

coordinated with other manufacturers 

and civil aviation authorities (CAAs) to 

use this process. As a result, EASA AD 

2020–0145 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2020–0145 

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 

the EASA AD 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 the EASA AD. Service 

information specified in EASA AD 

2020–0145 that is required for 

compliance with EASA AD 2020–0145 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2020–1113 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 128 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS * 

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Retained actions from AD 

2019-03-10.

1 work-hour × $85 per hour = 

$85, per inspection cycle.

$0 $85, per inspection cycle ....... $10,880, per inspection cycle. 

New proposed modifications .. 180 work-hours × $85 per 

hour = $15,300.

* Table does not include estimated costs for reporting. 

The FAA estimates that it would take 

about 1 work-hour per product to 

comply with the proposed reporting 

requirement in this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, the FAA estimates the 

cost of reporting the inspection results 

on U.S. operators to be $85, or $85 per 

product.

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this proposed AD is 2120– 

0056. The paperwork cost associated 

with this proposed AD has been 

detailed in the Costs of Compliance 

section of this document and includes 

time for reviewing instructions, as well 

as completing and reviewing the 

collection of information. Therefore, all 

reporting associated with this proposed 

AD is mandatory. Comments concerning 

the accuracy of this burden and 

suggestions for reducing the burden 

should be directed to Information 

Collection Clearance Officer, Federal 

Aviation Administration, 10101 

Hillwood Parkway, Fort Worth, TX 

76177–1524. 

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) 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.

jbell on DSKJLSW7X2PROD with PROPOSALS
78974 Federal Register / Vol. 85, No. 236 / Tuesday, December 8, 2020 / Proposed Rules 

(e) Reason 

This AD was prompted by reports of cracks 

in main landing gear (MLG) leg components, 

and a determination that additional actions 

(including inspections, modifications, and 

out-of-roundness checks) are needed to 

address the unsafe condition. The FAA is 

issuing this AD to address cracking of certain 

components in the MLG leg, which could 

result in an MLG collapse, and consequent 

damage to the airplane and injury to the 

airplane occupant. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, European Union Aviation 

Safety Agency (EASA) AD 2020–0145, dated 

July 1, 2020 (EASA AD 2020–0145). 

(h) Exceptions to EASA AD 2020–0145 

(1) Where EASA AD 2020–0145 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) Where EASA AD 2020–0145 refers to 

the effective date of EASA AD 2018–0170, 

this AD requires using March 29, 2019 (the 

effective date of AD 2019–03–10). 

(3) The ‘‘Remarks’’ section of EASA AD 

2020–0145 does not apply to this AD. 

(4) Paragraph (3) of EASA AD 2020–0145 

specifies to ‘‘send all removed pins for an 

out-of-roundness check.’’ For this AD, do an 

inspection of each pin for out-of-roundness, 

in accordance with the service information 

specified in EASA AD 2020–0145. 

(5) Paragraph (3) of EASA AD 2020–0145 

specifies to report inspection results to 

Safran within a certain compliance time. For 

this AD, report inspection results at the 

applicable time specified in paragraph 

(h)(5)(i) or (ii) of this AD. 

(i) If the inspection was done on or after 

the effective date of this AD: Submit the 

report within 30 days after the inspection. 

(ii) If the inspection was done before the 

effective date of this AD: Submit the report 

within 30 days after the effective date of this 

AD. 

(i) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft 

Section, International Validation 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 responsible Flight 

Standards Office, as appropriate. If sending 

information directly to the Large Aircraft 

Section, International Validation Branch, 

send it to the attention of the person 

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

Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any 

approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the responsible 

Flight Standards Office. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain instructions 

from a manufacturer, the instructions must 

be accomplished using a method approved 

by the Manager, Large Aircraft Section, 

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) Required for Compliance (RC): For any 

service information referenced in EASA AD 

2020–0145 that contains RC procedures and 

tests: Except as required by paragraph (i)(2) 

of this AD, RC 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 be 

done and the airplane can be put back in an 

airworthy condition. Any substitutions or 

changes to procedures or tests identified as 

RC require approval of an AMOC. 

(4) Paperwork Reduction Act Burden 

Statement: A federal agency may not conduct 

or sponsor, and a person is not required to 

respond to, nor shall a person be subject to 

a penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork Reduction 

Act unless that collection of information 

displays a current valid OMB Control 

Number. The OMB Control Number for this 

information collection is 2120–0056. Public 

reporting for this collection of information is 

estimated to be approximately 1 hour per 

response, including the time for reviewing 

instructions, searching existing data sources, 

gathering and maintaining the data needed, 

and completing and reviewing the collection 

of information. All responses to this 

collection of information are mandatory as 

required by this AD. Send comments 

regarding this burden estimate or any other 

aspect of this collection of information,

14 CFR Part 39 

[Docket No. FAA–2020–1112; Project 

Identifier MCAI–2020–01127–T] 

RIN 2120–AA64 

Airworthiness Directives; ATR—GIE 

Avions de Transport Re ́gional 

Airplanes 

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 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42 airplanes; and 

Model ATR72 airplanes. This proposed 

AD was prompted by in-service data 

which revealed that the minimum 

operating airspeeds in severe icing 

conditions, computed to provide 

adequate stall margins, do not provide 

sufficient margins to stall speeds at high 

bank angle while exiting severe icing 

conditions. This proposed AD would 

require revising the existing aircraft 

flight manual (AFM) and applicable 

corresponding operational procedures to 

provide emergency procedures and 

limitations for operating in severe icing 

conditions, 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 January 22, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

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

instructions for submitting comments. 

• Fax: 202–493–2251.
