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 indicating that during 

production, the manual opening and 

closing of the over-wing emergency exit 

door (OWEED) prior to the installation 

of the OWEED interior panel could have 

resulted in damaged insulation blankets 

below the left and right OWEEDs. This 

AD requires a one-time inspection for 

damage of the insulation blankets below 

the left and right OWEEDs, and 

replacement if necessary, as specified in 

a Transport Canada Civil Aviation 

(TCCA) 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 March 3, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 3, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

TCCA, which is the aviation authority 

for Canada, issued TCCA AD CF–2021– 

03 on February 11, 2021 (TCCA AD CF– 

2021–03) (also referred to 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. 

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 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 87, No. 18 / Thursday, January 27, 2022 / Rules and Regulations 4149 

BD–500–1A11 airplanes. The NPRM 

published in the Federal Register on 

August 3, 2021 (86 FR 41788). The 

NPRM was prompted by a report 

indicating that during production, the 

manual opening and closing of the 

OWEED prior to the installation of the 

OWEED interior panel could have 

resulted in damaged insulation blankets 

below the left and right OWEEDs. The 

NPRM proposed to require a one-time 

inspection for damage of the insulation 

blankets below the left and right 

OWEEDs, and replacement if necessary, 

as specified in TCCA AD CF–2021–03. 

The FAA is issuing this AD to address 

potential damage to the insulation 

blankets, which could result in delayed 

passenger evacuation in the event of 

post-crash/post-impact fire events 

outside the airplane. See the MCAI for 

additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

one commenter, Delta Air Lines (DAL). 

The following presents the comment 

received on the NPRM and the FAA’s 

response to that comment. 

Request To Omit Exception 

DAL asked that the FAA remove the 

exception identified in paragraph (h)(2) 

of the proposed AD, since it provides no 

value to the end product. DAL stated 

that the instructions in TCCA AD 

CF-2021-03, and Airbus Canada Service 

Bulletin BD500-258003, Issue 001, dated 

November 5, 2020, include 

implementation of corrective action for 

discrepancies, and neither allows 

deferring any corrective actions beyond 

maintenance after the inspection is done 

and corrosion is documented. 

The FAA does not agree with the 

commenter’s request. This exception 

was included to require replacement of 

any damaged insulation blanket before 

further flight, because no separate 

compliance time was provided in the 

referenced service information for the 

corrective actions. Without the 

exception specified in paragraph (h)(2) 

of this AD, operators could wait until 

the end of the compliance time (4,500 

flight hours or 24 months after the 

effective date of this AD, whichever 

occurs first) to replace damaged 

insulation blankets, instead of replacing 

them before further flight. Therefore, the 

FAA has not changed this AD in this 

regard. 

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 

TCCA AD CF–2021–03 describes 

procedures for a one-time visual 

inspection for damage of the insulation 

blankets below the left and right 

OWEEDs, and replacement of any 

damaged insulation blankets. 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 33 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 $8,415 

The FAA estimates the following 

costs to do any necessary on-condition 

action that will 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 oncondition action: 

ESTIMATED COSTS OF ON-CONDITION ACTION

Labor cost Parts cost Cost per 

product 

2 work-hours × $85 per hour = $170 ...................................................................................................................... $150 $320 

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; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 747–8F and 

747–8 series airplanes and Model 777 

airplanes. This AD was prompted by a 

determination that radio altimeters 

cannot be relied upon to perform their 

intended function if they experience 

interference from wireless broadband 

operations in the 3.7–3.98 GHz 

frequency band (5G C-Band), and a 

recent determination that this 

interference may affect multiple 

airplane systems using radio altimeter 

data, including the pitch control laws, 

including those that provide tail strike 

protection, regardless of the approach 

type or weather. This AD requires 

revising the limitations section of the 

existing airplane flight manual (AFM) to 

incorporate limitations prohibiting 

dispatching or releasing to airports, and 

approaches or landings on runways, 

when in the presence of 5G C-Band 

interference as identified by Notices to 

Air Missions (NOTAMs). The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective January 27, 

2022.
