SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2020–0255, 

dated November 13, 2020 (EASA AD 

2020–0255) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for certain Airbus SAS 

Model A330–201, –202, –203, –223, 

–243, –301, –302, –303, –321, –322, 

–323, –341, –342, and –343 airplanes; 

and Model A340–211, –212, –213, –311, 

–312, –313, –541, –542, –642, and –643 

airplanes. Model A340–542 and A340– 

643 airplanes are not certificated by the 

FAA and are not included on the U.S. 

type certificate data sheet; this AD 

therefore does not include those 

airplanes in the applicability. 


jbell on DSKJLSW7X2PROD with RULES
31096 Federal Register / Vol. 86, No. 111 / Friday, June 11, 2021 / Rules and Regulations 

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 SAS Model 

A330–200, A330–300, A340–200, A340– 

300, A340–500, and A340–600 series 

airplanes. The NPRM published in the 

Federal Register on March 11, 2021 (86 

FR 13836). The NPRM was prompted by 

reports that, for certain LDMCR units, 

the connection of a certain halon outlet 

tube to the outlet of a certain fire 

extinguisher bottle may be incorrect. 

The NPRM proposed to require 

replacing each affected halon outlet tube 

with a flexible hose, as specified in 

EASA AD 2020–0255. 

The FAA is issuing this AD to address 

the possible incorrect connection of the 

halon outlet tube as described 

previously, which, in case of a fire 

inside the LDMCR, could lead to 

disconnection of the tube, possibly 

resulting in reduced concentration of 

fire suppressing agent at any location 

inside the LDMCR. 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 

Pilots Association, International 

(ALPA), stated that it supports the 

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 

EASA AD 2020–0255 describes 

procedures for replacing each affected 

halon outlet tube in the LDMCR with a 

flexible hose. 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 123 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 .......................................................................................... $(*) $340 $41,820 

* The FAA has received no definitive data on which to base the parts cost estimates for the replacements specified in this AD. 

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.

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–03– 

10, which applied to all Airbus SAS 

Model A300 series airplanes; and Model 

A300 B4–600, B4–600R, and F4–600R 

series airplanes, and Model A300 C4– 

605R Variant F airplanes (collectively 

called Model A300–600 series 

airplanes). AD 2019–03–10 required 

repetitive detailed visual inspections of 

the main landing gear (MLG) leg 

components and replacement of the 

MLG leg if cracked components are 

found. This AD continues to require the 

actions required by AD 2019–03–10. For 

certain airplanes, this AD also requires 

modification of the MLG hinge arm by 

installing improved MLG hinge arm/ 

barrel pins; an out-of-roundness check 

of removed pins; repetitive inspections 

of any affected pins and the associated 

connecting rod bushes, and replacement 

of the MLG leg if cracked components 

are found; and installation of an 

improved spacer; as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference. This AD was prompted by 

reports of cracks in MLG leg 

components and a determination that 

additional actions (including 

inspections, modifications, and checks) 

are needed to address the unsafe 

condition. The FAA is issuing this AD 

to address the unsafe condition on these 

products.
