86462 Federal Register / Vol. 85, No. 250 / Wednesday, December 30, 2020 / Rules and Regulations 

0109, dated May 15, 2020 (EASA AD 2020– 

0109). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Reason 

This AD was prompted by a report that 

during the assembly of the section 19 skin to 

frame (FR) 98 joint of the fuselage, the gaps 

found on self-aligning nuts for eight fasteners 

were out of tolerance. The FAA is issuing 

this AD to address gaps that are out of 

tolerance, which could reduce the fatigue 

and damage tolerance properties of the 

affected area, and possibly affect the 

structural integrity of the rear cone of the 

fuselage. 

(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, EASA AD 2020–0109. 

(h) Exceptions to EASA AD 2020–0109 

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

2020–0109 does not apply to this AD. 

(2) Where paragraph (2) of EASA AD 2020– 

0109 specifies actions if ‘‘any discrepancy is 

detected, as defined in the SB,’’ for this AD 

a discrepancy is defined as any crack or 

damage. 

(3) Where Airbus Service Bulletin A350– 

53–P057, dated February 21, 2020 

(referenced in EASA AD 2020–0109), 

specifies Airbus task A350–A–53–XX–P057– 

01001–720A–A and task A350–A–53–XX– 

P057–02001–720A–A, for instructions for 

installing the new fasteners, and those 

instructions specify to refer to ‘‘ASR A350– 

A–20–51–01ZZZ–25BZ–A,’’ for the purposes 

of this AD, the correct reference is ‘‘AMM 

Maintenance Procedure A350–A–20–51– 

01ZZZ–25BZ–A.’’ 

(i) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance

the DOA, the approval must include the 

DOA-authorized signature. 

(3) Required for Compliance (RC): Except 

as required by paragraphs (h)(2) and (3) and 

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 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.

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Canada Limited Partnership 

Model BD–500–1A10 and BD–500– 

1A11 airplanes. This AD was prompted 

by a report that during installation on 

the final assembly line, a foreign object 

damage (FOD) protective end cap was 

not removed from an extraction duct of 

the crew oxygen system. The protective 

end cap must be removed to prevent a 

build-up of oxygen under the flight deck 

floor, which is a fire risk. This AD 

requires inspecting the air extraction 

duct installation to determine if a 

protective end cap is installed, and 

removing any protective end cap found. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective February 3, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 3, 2021.

SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2020–19, dated May 26, 2020 (also 

referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain Airbus Canada 

Limited Partnership Model BD–500– 

1A10 and BD–500–1A11 airplanes. You 

may examine the MCAI in the AD 

docket on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2020– 

0683. 

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 Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. The NPRM 

published in the Federal Register on 

August 11, 2020 (85 FR 48480). The 

NPRM was prompted by a report that 

during installation on the final assembly 

line, a FOD protective end cap was not 

removed from an extraction duct of the 

crew oxygen system. The protective end 

cap must be removed to prevent a buildup of oxygen under the flight deck floor, 

which is a fire risk. The NPRM 

proposed to require inspecting the air 

extraction duct installation to determine 

if a protective end cap is installed, and 

removing any protective end cap found. 

The FAA is issuing this AD to address 

this possible ignition source, which 

could result in an oxygen-fed fire. See 

the MCAI for additional background 

information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The following presents 

the comments received on the NPRM 

and the FAA’s response to each 

comment. 

Support for the NPRM 

The Air Line Pilots Association, 

International indicated its support for 

the NPRM. 

Request To Refer to a Specific Service 

Information Procedure 

Delta Air Lines, Inc. (DAL) requested 

that paragraph (g) of the proposed AD 

refer to Step 2.2 of the Accomplishment 

Instructions of Airbus Canada Limited 

Partnership A220 Service Bulletin 

BD500–351004, Issue 001, dated April 

8, 2020, instead of referring to the entire 

Accomplishment Instructions. DAL 

stated that only Step 2.2 of the 

Accomplishment Instructions of the 

referenced service information provides 

the required steps for performing the 

inspection and corrective action 

required by the proposed AD. DAL 

noted that the current language should 

be more specific when referring to these 

tasks. 

The FAA agrees with the commenter’s 

request. Only Step 2.2 of the 

Accomplishment Instructions of Airbus 

Canada Limited Partnership A220 

Service Bulletin BD500–351004, Issue 

001, dated April 8, 2020, is necessary to 

correct the specified unsafe condition. 

The remaining portions of the 

Accomplishment Instructions contain 

the access and close procedures, which 

are not required to address the 

identified unsafe condition. The FAA 

has changed paragraph (g) of this AD to 

reference only Step 2.2 of the 

Accomplishment Instructions of the 

referenced service information. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule with the change described 

previously and minor editorial changes. 

The FAA has determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

The FAA also determined that this 

change will not increase the economic 

burden on any operator or increase the 

scope of this final rule. 

Related Service Information Under 1 

CFR Part 51 

Airbus Canada Limited Partnership 

has issued A220 Service Bulletin 

BD500–351004, Issue 001, dated April 

8, 2020. This service information 

describes procedures for a general visual 

inspection of the extraction duct of the 

crew oxygen system to determine if a 

protective end cap is installed, and 

removing any protective end cap found. 

This service information 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 20 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 

3 work-hours × $85 per hour = $255 .......................................................................................... $0 $255 $5,100 

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 

86464 Federal Register / Vol. 85, No. 250 / Wednesday, December 30, 2020 / 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
