SUPPLEMENTARY INFORMATION: 

Background 

TCCA, which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–01, dated January 8, 2021 (TCCA 

AD CF–2021–01) (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 

August 25, 2021 (86 FR 47424). The 

NPRM was prompted by reports of loose 

powerplant FIREX interconnection 

hoses, and in one instance a hose was 

found disconnected. An investigation by 

the manufacturer determined that if the 

instructions for connecting the FIREX 

hose are not followed properly, hoses 

can become loose or disconnected. The 

NPRM proposed to require replacing 

certain existing FIREX hose assemblies 

with a newly designed FIREX hose 

assembly, as specified in TCCA AD CF– 

2021–01. 

The FAA is issuing this AD to address 

the possibility that fire extinguishing 

agent may not be effectively applied 

should a fire occur within a powerplant 

assembly that has a partially or 

completely disconnected FIREX hose, 

which could result in the inability to 

put out a fire in the engine. See the 

MCAI for additional background 

information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

Air Line Pilots Association, 

International, who supported the NPRM 

without change. 

The FAA received an additional 

comment from Delta Air Lines. The 

following presents the comment 

received on the NPRM and the FAA’s 

response. 

Request To Withdraw the Proposed AD 

Delta Air Lines (DAL) requested that 

the FAA withdraw the proposed AD. 

DAL stated that it had already 

accomplished the required actions of 

paragraph (g) of the proposed AD by 

accomplishing the actions specified in 

Airbus Canada Limited Partnership 

Service Bulletin (SB) BD500–262003 

Issue 002, dated January 7, 2020. 

The FAA does not agree with the 

request to withdraw this AD. Even 

though DAL is the only current U.S. 

operator of the applicable airplanes, the 

AD must still be issued in case of any 

future imports of the airplanes. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments 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.

FIREX hose assemblies on each 

powerplant with a newly designed 

FIREX hose assembly with provisions 

for the installation of safety cables at 

each end, in order to prevent the hose 

from becoming loose or disconnected. 

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 36 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 

5 work-hours × $85 per hour = $425 .......................................................................................... $13,012 $13,437 $483,732 

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 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Fiberglas-Technik Rudolf 

Lindner GmbH & Co. KG Model G102 

ASTIR CS, G103 TWIN ASTIR, G103 

TWIN II, G103A TWIN II ACRO, G103C 

TWIN III ACRO, and G 103 C TWIN III 

SL gliders. The NPRM published in the 

Federal Register on October 29, 2021 

(86 FR 59903). The NPRM was 

prompted by MCAI originated by the 

European Union Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union. EASA issued EASA AD 2020– 

0138, dated June 19, 2020 (referred to 

after this as ‘‘the MCAI’’), to address an 

unsafe condition on Fiberglas-Technik 

Rudolf Lindner GmbH & Co. KG Model 

G102 ASTIR CS, G103 TWIN ASTIR, 

G103 TWIN II, G103A TWIN II ACRO, 

G103C TWIN III ACRO, and G 103 C 

TWIN III SL gliders. The MCAI states: 

During a routine inspection, a severely 

corroded elevator control pushrod was found 

in the vertical fin on a Grob TWIN ASTIR 

sailplane. The technical investigation results 

revealed that water had soaked into the 

elevator control pushrod, causing the 

corrosion damage and subsequent 

considerable weakening of the steel tube 

pushrod. 

This condition, if not detected and 

corrected, could lead to failure of the elevator 

control pushrod, possibly resulting in loss of 

control of the sailplane. 

To address this unsafe condition,
