AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–01– 

17, which applied to all Airbus SAS 

Model A318, A319, A320, and A321 

series airplanes. AD 2020–01–17 

required repetitive checks of the 

pressure gauges on the inflation 

reservoir of each emergency escape 

slide/raft to determine the amount of 

pressure and, depending on findings, 

accomplishment of applicable corrective 

actions. This AD retains the 

requirements of AD 2020–01–17, 

expands the list of affected parts to be 

checked, and provides optional 

terminating action for the repetitive 

checks; as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

This AD was prompted by the 

determination that certain parts that 

were not identified in AD 2020–01–17 

are also subject to the unsafe condition. 

The FAA is issuing this AD to address 

the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued AD 2020–01–17, 

Amendment 39–19823 (85 FR 5310, 


jbell on DSKJLSW7X2PROD with RULES
79416 Federal Register / Vol. 85, No. 238 / Thursday, December 10, 2020 / Rules and Regulations 

January 30, 2020) (AD 2020–01–17), 

which applied to all Airbus SAS Model 

A318, A319, A320, and A321 series 

airplanes. AD 2020–01–17 required 

repetitive checks of the pressure gauges 

on the inflation reservoir of each 

emergency escape slide/raft to 

determine the amount of pressure and, 

depending on findings, accomplishment 

of applicable corrective actions. The 

FAA issued AD 2020–01–17 to address 

insufficient reservoir pressure in an 

emergency escape slide/raft, which 

would prevent the deployment of the 

emergency escape slide/raft during an 

emergency, possibly resulting in injury 

to the occupants. 

Actions Since AD 2020–01–17 Was 

Issued 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0236, dated October 27, 2020 

(EASA AD 2020–0236) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Airbus SAS Model A318 series 

airplanes; Model A319–111, –112, –113, 

–114, –115, –131, –132, –133, –151N, 

–153N, and –171N airplanes; Model 

A320–211, –212, –214, –215, –216, 

–231, –232, –233, –251N, –252N, 

–253N, –271N, –272N, and –273N 

airplanes; and Model A321 series 

airplanes. Model A319–153N and 

A320–215 airplanes are not certified by 

the FAA and are not included on the 

U.S. type certificate data sheet; this AD 

therefore does not include those 

airplanes in the applicability. 

This AD was prompted by a report 

that during airplane boarding a loud 

bang was heard. A subsequent 

inspection revealed that one emergency 

escape slide/raft was found with zero 

reservoir pressure, due to a burst 

rupture disk assembly in the inflation 

reservoir, which was probably caused 

by a manufacturing defect. This AD was 

also prompted by the determination that 

additional parts are subject to the unsafe 

condition, and by the availability of an 

optional terminating action for the 

repetitive checks. The FAA is issuing 

this AD to address insufficient reservoir 

pressure in an emergency escape slide/ 

raft, which would prevent the 

deployment of the emergency escape 

slide/raft during an emergency, possibly 

resulting in injury to the occupants. See 

the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0236 describes 

procedures for repetitive checks of the 

pressure gauge on the inflation reservoir 

of each emergency escape slide/slide 

raft to determine the amount of 

pressure, and applicable corrective 

actions. The corrective actions include, 

among other things, replacement of any 

affected emergency escape slide/raft or 

inflation reservoir. EASA AD 2020–0236 

also describes procedures for a 

modification or replacement of affected 

parts, which would eliminate the need 

for the repetitive pressure checks. 

This AD also requires EASA AD 

2019–0316, dated December 23, 2019, 

which the Director of the Federal 

Register approved for incorporation by 

reference as of February 14, 2020 (85 FR 

5310, January 30, 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. 

FAA’s Determination 

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 issuing this AD 

because the FAA has evaluated all 

pertinent information and determined 

the unsafe condition exists and is likely 

to exist or develop on other products of 

the same type design. 

Requirements of This AD 

This AD retains the requirements of 

AD 2020–01–17, and requires 

accomplishing the actions specified in 

EASA AD 2020–0236 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Accomplishment of the initial pressure 

check specified in EASA AD 2020–0236 

terminates the requirements of AD 

2020–01–17. 

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 

2020–0236 is incorporated by reference 

in this AD. This AD, therefore, requires 

compliance with EASA AD 2020–0236 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this 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 2020–0236 that is required for 

compliance with EASA AD 2020–0236 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2020– 

1105. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because if a rupture disk assembly 

in the inflation reservoir of an 

emergency escape slide/slide raft burst, 

it would result in a sudden loss of 

reservoir pressure and prevent the 

deployment of the emergency escape 

slide/raft during an emergency, possibly 

resulting in injury to the occupants. In 

addition, the compliance time for the 

required action is shorter than the time 

necessary for the public to comment and 

for publication of the final rule. 

Therefore, the FAA finds good cause 

that notice and opportunity for prior 

public comment are impracticable. In 

addition, for the reasons stated above, 

the FAA finds that good cause exists for 

making this amendment effective in less 

than 30 days. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2020–1105; Project Identifier 

MCAI–2020–01459–T’’ at the beginning 

of your comments. The most helpful 

comments reference a specific portion of 

the final rule, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this final rule 

because of those comments. 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 85, No. 238 / Thursday, December 10, 2020 / Rules and Regulations 79417 

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 final rule. 

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 AD 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 AD, 

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 AD. Submissions containing CBI 

should be sent to Sanjay Ralhan, 

Aerospace Engineer, Large Aircraft 

Section, International Validation 

Branch, FAA, 2200 South 216th St., Des 

Moines, WA 98198; telephone and fax 

206–231–3223; email Sanjay.Ralhan@

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. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 1,680 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 

1 work-hour × $85 per hour = $85 ......................................... $0 $85 $142,800 per check. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions 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 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that 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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

reservoir, which was probably caused by a 

manufacturing defect. The FAA is issuing 

this AD to address insufficient reservoir 

pressure in an emergency escape slide/raft, 

which would prevent the deployment of the 

emergency escape slide/raft during an 

emergency, possibly resulting in injury to the 

occupants.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2018–16– 

05, which applied to certain The Boeing 

Company Model 757 airplanes. AD 

2018–16–05 required repetitive 

inspections for skin cracking and shim 

migration at the upper link drag fittings, 

diagonal brace cracking, and fastener 

looseness; and applicable on-condition 

actions. This AD retains the actions 

required by AD 2018–16–05, reduces 

the compliance times for certain 

inspections, and adds repetitive 

inspections at certain fastener hole 

locations and applicable on-condition 

actions. This AD was prompted by 

reports of bolt rotation in the engine 

drag fitting joint and fastener heads; an 

inspection of the fastener holes revealed 

that cracks were found in the skin. This 

AD was also prompted by a report of 

multiple cracks in the drag fitting at 

fastener holes found during an 

inspection required by AD 2018–16–05. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective January 14, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 14, 2021.
