ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all De 

Havilland Aircraft of Canada Limited 

Model DHC–8–401 and –402 airplanes.

actions if necessary, and replacing the 

coupling and seals with a redesigned 

assembly. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD is effective May 10, 

2022. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–11, dated March 29, 2021 (TCCA 

AD CF–2021–11) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all De Havilland 

Aircraft of Canada Limited Model DHC– 

8–401 and –402 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–2021– 

1068. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all De Havilland Aircraft of 

Canada Limited Model DHC–8–401 and 

–402 airplanes. The NPRM published in 

the Federal Register on December 17, 

2021 (86 FR 71594). The NPRM was 

prompted by reports of bleed air leaks 

in the wing box area and failure of the 

leak detection shroud. The NPRM 

proposed to require removing and 

inspecting the affected V-band coupling 

and check valve seals, doing corrective 

actions if necessary, and replacing the 

coupling and seals with a redesigned 

assembly. The FAA is issuing this AD 

to address the possibility of undetected 

hot engine bleed air being directed onto 

aircraft structure, the main landing gear 

(MLG) emergency release cable, and the 

static air temperature (SAT) sensor, 

which could cause the main landing 

gear emergency release cable to 

malfunction. See the MCAI for 

additional background information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA has considered 

the comment received. The Air Line 


jspears on DSK121TN23PROD with RULES1
19618 Federal Register / Vol. 87, No. 65 / Tuesday, April 5, 2022 / Rules and Regulations 

Pilots Association, International 

(ALPA), indicated its support for NPRM. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for 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. 

Related Service Information Under 1 

CFR Part 51 

De Havilland Aircraft of Canada 

Limited has issued Service Bulletin 84– 

36–06, dated December 15, 2020. This 

service information describes 

procedures for removing the affected Vband coupling and check valve seals, 

doing a visual inspection of the 

coupling covers and surrounding area 

for damage due to bleed air leakage, and 

replacing the coupling and seals with a 

redesigned assembly. 

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 82 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 

4 work-hours × $85 per hour = $340 .......................................................................................... $75 $415 $34,030 

The FAA estimates the following 

costs to do any necessary coupling cover 

replacement that would 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 on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTION

Labor cost Parts cost Cost per 

product 

1 work-hour × $85 per hour = $85 .......................................................................................................................... $5 $90 

The FAA has received no definitive 

data on which to base the cost estimates 

for correcting damage in the area 

surrounding the coupling covers. 

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; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2018–09– 

09, which applied to certain Airbus 

Model A318 and A319 series airplanes; 

all Model A320–211, –212, –214, –216, 

–231, –232, and –233 airplanes; and all 

Model A321–111, –112, –131, –211, 

–212, –213, –231, and –232 airplanes. 

AD 2018–09–09 required modifying the 

holes of the upper cleat to upper 

stringer attachments at certain areas of 

the left- and right-hand wings. Since the 

FAA issued AD 2018–09–09, additional 

affected configurations were identified 

and, for certain airplanes, it was 

determined that additional modification 

work and revised compliance times are 

necessary. This AD retains the 

requirements of AD 2018–09–09 and 

adds airplanes, requires different 

compliance times for certain airplane 

configurations, and, for certain 

airplanes, requires additional 

modifications or reduces compliance 

times, 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 May 10, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 10, 2022.
