AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus SAS Model A350–941 and –1041 

airplanes. This AD was prompted by a 

report that due to an issue with the 

flight warning system (FWS) logic, it is 

possible that the ‘‘AIR Auxiliary Power 

Unit (APU) BLEED LEAK’’ electronic 

centralized aircraft monitoring (ECAM) 

alert can trigger several times. This AD 

requires revising the airplane flight 

manual (AFM) to incorporate 

procedures related to an APU bleed 

leak. We are issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD becomes effective 

January 14, 2019. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 14, 2019. 

We must receive comments on this 

AD by February 11, 2019.

SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2018–0246, dated November 13, 2018 

(‘‘EASA AD 2018–0246’’) (also referred 

to as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Airbus SAS Model A350–941 

and –1041 airplanes. The MCAI states: 

Due to a misbehaviour in the establishment 

of the FWS logic, it is possible that the <<AIR 

Auxiliary Power Unit (APU) BLEED LEAK>> 

Electronic Centralized Aircraft Monitoring 

(ECAM) alert triggers several times. 

Therefore, several resets of the engine 1 bleed 

may need to be performed. Each time the 

flight crew performs an engine 1 bleed reset, 

structural parts are exposed to hot air for 

several seconds. 

This condition, if not corrected, could lead 

to exposure of critical locations and 

surrounding structure to heat stress, possibly 

resulting in reduced structural integrity of 

the aeroplane. 

To address this potential unsafe condition, 

Airbus issued the AFM TR [temporary 

revision] to provide an updated procedure 

<<AIR APU BLEED LEAK>> operations, and 

Flight Operations Transmission (FOT) 

999.0062/18, informing operators that Airbus 

provides two different Temporary Quick 

Changes (ATQC) to the ECAM, as applicable, 

depending on the installed FWS standard, 

either STD S4/2.0 or STD S5/2.2. 

Installation of that ATQC is already 

required by EASA AD 2018–0213, related to 

a different unsafe condition and is therefore 

not mandated again by this [EASA] AD [we 

are considering additional rulemaking to 

mandate incorporating the ATQCs]. 

For the reasons described above, this 

[EASA] AD requires only the amendment of 

the applicable AFM to update the procedures 

related to <<AIR APU BLEED LEAK>> 

operations. 

Related IBR Material Under 1 CFR Part 

51 

EASA AD 2018–0246 describes 

procedures for revising the AFM to 

incorporate procedures related to an 

APU bleed leak. 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, and it is publicly 

available through the EASA website. 

FAA’s Determination 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI referenced above. We are issuing 

this AD because we evaluated all 

pertinent information and determined 

the unsafe condition exists and is likely 

to exist or develop on other products of 

the same type design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2018– 

0246 described previously. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA worked with Airbus 

and EASA to develop a process to use 

certain EASA ADs as the primary source 

of information for compliance with 

requirements for corresponding FAA 

ADs. As a result, EASA AD 2018–0246 

will be incorporated by reference in the 

FAA final rule. This AD would, 

therefore, require compliance with the 

provisions specified in EASA AD 2018– 

0246, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Service 

information specified in EASA AD 

2018–0246 that is required for 

compliance with EASA AD 2018–0246 

will be available at http://

www.regulations.gov under Docket No. 


amozie on DSK3GDR082PROD with RULES
Federal Register / Vol. 83, No. 248 / Friday, December 28, 2018 / Rules and Regulations 67037 

FAA–2018–1062 after the FAA final 

rule is published. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because an issue with the FWS 

logic makes it possible that the ‘‘AIR 

APU BLEED LEAK’’ ECAM alert can 

trigger several times. An engine bleed 

reset in response to the ECAM alert 

could lead to exposure of critical 

locations and the surrounding structure 

to heat stress, possibly resulting in 

reduced structural integrity of the 

airplane. Therefore, we find good cause 

that notice and opportunity for prior 

public comment are impracticable. In 

addition, for the reason(s) stated above, 

we find that good cause exists for 

making this amendment effective in less 

than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2018–1062; 

Product Identifier 2018–NM–163–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD based on those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD affects 11 

airplanes of U.S. registry. We estimate 

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 

1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $935 

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. 

We are 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to transport category 

airplanes and associated appliances to 

the Director of the System Oversight 

Division. 

Regulatory Findings 

We determined that 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. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. 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.
