SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0047, 

dated February 16, 2021 (EASA AD 

2021–0047) (also referred to as the 

MCAI), to correct an unsafe condition 

for certain Dassault Aviation Model 

FALCON 7X, FALCON 900EX, and 

FALCON 2000EX 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 Dassault Aviation 

Model FALCON 7X, FALCON 900EX, 

and FALCON 2000EX airplanes. The 

NPRM published in the Federal 

Register on August 19, 2021 (86 FR 

46629). The NPRM was prompted by a 

report of an improper heat treatment 

process applied during the 

manufacturing of certain titanium 

screws. The NPRM proposed to require 

replacement of certain titanium screws, 

as specified in EASA AD 2021–0047. 

The FAA is issuing this AD to address 

failure of an affected screw installed in 

a critical location, possibly resulting in 

reduced structural integrity of the 

airplane. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from an 

anonymous commenter who supported 

the NPRM without change. 

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 

EASA AD 2021–0047 specifies 

procedures for replacement of certain 

Decomatic titanium screws (including 

an inspection of the bore dimension and 

corrective actions (oversizing or repair)). 

The EASA AD also restricts installation 

of certain Decomatic titanium screws. 

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 30 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 


khammond on DSKJM1Z7X2PROD with RULES
7026 Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Rules and Regulations 

ESTIMATED COSTS FOR REQUIRED ACTIONS

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

operators 

Up to 90 work-hours × $85 per hour = Up to $7,650 ............................. * $0 Up to $7,650 ................................... Up to $229,500. 

* The FAA has received no definitive information regarding cost estimates for these parts. 

According to the manufacturer, some 

or all of the costs of this AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

known costs in the cost estimate. 

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.

SUPPLEMENTARY INFORMATION: 

Background 

TCCA, which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2019–19R1, issued November 1, 2019 

(TCCA AD CF–2019–19R1) (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 

BD–500–1A11 airplanes. The NPRM 

published in the Federal Register on 

May 28, 2021 (86 FR 28719). The NPRM 

was prompted by reports of wear 

damage found between the bonding 

clamps and the fuel feed tubes inside 

the left- and right-hand fuel tanks. The 

NPRM proposed to require repetitive 

inspections of the fuel feed tubes for 

damage, replacement if necessary, and 

modification of the fuel feed line 

installation inside the left- and righthand fuel tanks, which would terminate 

the repetitive inspections, as specified 

in TCCA AD CF–2019–19R1. 

The FAA is issuing this AD to address 

failure of certain fuel feed tubes, which 

could lead to a severe fuel imbalance or 

fuel starvation of one engine, or in the 

event of the failure of multiple fuel 

tubes feeding both engines, could result 

in an in-flight shutdown of both 

engines. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

The FAA received an additional 

comment from Delta Air Lines (DAL). 

The following presents the comment 

received on the NPRM and the FAA’s 

response. 

Request for an Optional Method of 

Compliance 

DAL asked that the FAA add an 

optional method of compliance to the 

proposed AD. DAL recommended an 

additional exception be added in 

paragraph (h)(5) of the proposed AD to 

specify that: ‘‘It is acceptable to 

accomplish Airbus Canada Limited 

Partnership Service Bulletin BD500– 

282004, Issue No. 001, dated August 30, 

2019, concurrently with Airbus Canada 

Limited Partnership Service Bulletin 

BD500–282005, Issue No. 001, dated 

August 30, 2019, as terminating action 

for Part I and Part II of TCCA AD CF– 

2019–19R1.’’ DAL stated that Airbus 

Canada Limited Partnership Service 

Bulletin BD500–282005 (which is not 

required by the proposed AD) also 

modifies the fuel feed system. DAL 

noted that doing the service bulletins
