AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A318, A319, A320, and 

A321 series airplanes. This proposed 

AD was prompted by a determination 

that the maintenance actions for 

airplane systems susceptible to aging 

must be mandated. This proposed AD 

would require revising the maintenance 

or inspection program to incorporate 

more restrictive maintenance 

requirements and airworthiness 

limitations. We are proposing this AD to 

mitigate the risks associated with aging 

effects of airplane systems. Such aging 

effects could change the characteristics 

leading to an increased potential for 

failure, which could result in failure of 

certain life limited parts, and could 

reduce the structural integrity or reduce 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by September 26, 

2014.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2013–0146, 

dated July 16, 2013 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

The airworthiness limitations for Airbus 

aeroplanes are currently published in 

Airworthiness Limitations Section (ALS) 

documents. 

The airworthiness limitations applicable to 

the Ageing Systems Maintenance (ASM) are 

given in Airbus A318/A319/A320/A320/

A321 ALS Part 4, which is approved by 

[European Aviation Safety Agency] EASA. 

Revision 01 of AIRBUS A318/A319/A320/ 

A321 ALS Part 4 introduces more restrictive 

maintenance requirements and/or 

airworthiness limitations. Failure to comply 

with these instructions could result in an 

unsafe condition. 

* * * * * 

You may examine the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0526. 

Relevant Service Information 

Airbus has issued A318/A319/A320/

A321 Airworthiness Limitations 

Section, ALS Part 4, ‘‘Ageing Systems 

Maintenance,’’ dated June 15, 2012. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

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 and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

This proposed AD requires revisions 

to certain operator maintenance 

documents to include new or revised 

actions (e.g., inspections). Compliance 

with these actions is required by section 

91.403(c) of the Federal Aviation 

Regulations (14 CFR 91.403(c)). For 

airplanes that have been previously 

modified, altered, or repaired in the 

areas addressed by these actions, an 

operator might not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply 

with 14 CFR 91.403(c), the operator 

must request approval of an alternative 

method of compliance (AMOC) in 

accordance with the provisions of 

paragraph (i) of this proposed AD. The 

request should include a description of 

changes to the required inspections that 

will ensure the continued operational 

safety of the airplane. 

Difference Between This Proposed AD 

and the MCAI 

The EASA AD specifies that if there 

are findings from the Airworthiness 

Limitations Section (ALS) inspection 

tasks, then corrective action must be 

accomplished in accordance with 

Airbus maintenance documentation. 

However, this proposed AD does not 

include that requirement because 

operators of U.S.-registered airplanes are 

required by general airworthiness and 

operational regulations to use FAAacceptable methods when performing 

maintenance. We consider those 

methods to be adequate to address any 

corrective actions necessitated by the 

findings of ALS inspections required by 

this proposed AD. 

‘‘Contacting the Manufacturer’’ 

Paragraph in This Proposed AD 

Since late 2006, we have included a 

standard paragraph titled ‘‘Airworthy 

Product’’ in all MCAI ADs in which the 

FAA develops an AD based on a foreign 

authority’s AD. 

We have become aware that some 

operators have misunderstood or 

misinterpreted the Airworthy Product 

paragraph to allow the owner/operator 

to use messages provided by the 

manufacturer as approval of deviations 

during the accomplishment of an ADmandated action. The Airworthy 

Product paragraph does not approve 

messages or other information provided 

by the manufacturer for deviations to 

the requirements of the AD-mandated 

actions. The Airworthy Product 

paragraph only addresses the 

requirement to contact the manufacturer 

for corrective actions for the identified 

unsafe condition and does not cover 

deviations from other AD requirements. 

However, deviations to AD-required 

actions are addressed in 14 CFR 39.17, 

and anyone may request the approval 

for an alternative method of compliance 

to the AD-required actions using the 

procedures found in 14 CFR 39.19. 

To address this misunderstanding and 

misinterpretation of the Airworthy 

Product paragraph, we have changed the 

paragraph and retitled it ‘‘Contacting the 

Manufacturer.’’ This paragraph now 

clarifies that for any requirement in this 

proposed AD to obtain corrective 

actions from a manufacturer, the action 

must be accomplished using a method 

approved by the FAA, the European 

Aviation Safety Agency (EASA), or 

Airbus’s EASA DOA. 

The Contacting the Manufacturer 

paragraph also clarifies that, if approved 

by the DOA, the approval must include 

the DOA-authorized signature. The DOA 

signature indicates that the data and 

information contained in the document 

are EASA-approved, which is also FAAapproved. Messages and other 

information provided by the 

manufacturer that do not contain the 

DOA-authorized signature approval are 

not EASA-approved, unless EASA 

directly approves the manufacturer’s 

message or other information. 

This clarification does not remove 

flexibility previously afforded by the 

Airworthy Product paragraph. 

Consistent with long-standing FAA 

policy, such flexibility was never 

intended for required actions. This is 

also consistent with the 

recommendation of the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee to increase 

flexibility in complying with ADs by 

identifying those actions in 

manufacturers’ service instructions that 

are ‘‘Required for Compliance’’ with 

ADs. We continue to work with 

manufacturers to implement this 

recommendation. But once we 

determine that an action is required, any 

deviation from the requirement must be 

approved as an alternative method of 

compliance.

47030 Federal Register / Vol. 79, No. 155 / Tuesday, August 12, 2014 / Proposed Rules 

Costs of Compliance 

We estimate that this proposed AD 

affects 851 airplanes of U.S. registry. We 

also estimate that it would take about 1 

work-hour per product to comply with 

the basic requirements of this proposed 

AD. The average labor rate is $85 per 

work-hour. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $72,335, or $85 per 

product. 

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. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Dassault Aviation Model MystereFalcon 50 airplanes. This proposed AD 

was prompted by a report of an 

untimely and intermittent indication of 

slat activity due to chafing of the 

electrical wiring under the glare shield 

and behind the flight deck front panel. 

This proposed AD would require 

installing two protective plates between 

the electrical wiring under the glare 

shield and the engine fire pull handles. 

We are proposing this AD to prevent 

chafing of the electrical wiring, which 

could result in a short circuit and 

generation of smoke in the cockpit, 

potential loss of several functions 

essential for safe flight, and consequent 

reduced controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by September 26,

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2014–0024, 

dated January 23, 2014 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Dassault Aviation Model 

Mystere-Falcon 50 airplanes. The MCAI 

states: 

One operator experienced an untimely and 

intermittent indication of slat activity on his 

aeroplane. The results of the subsequent 

investigation revealed that electrical wiring 

under the glare shield and behind the flight 

deck front panel was chafing with hardware 

and was short-circuited to ground. This 

situation may have resulted from an incorrect 

installation of the wiring during a previous 

maintenance action in the area. A design 

review identified a lack of protection of the 

affected electrical wiring bundle, which 

would have prevented damage caused by 

chafing with aeroplane structural parts. 

This condition, if not corrected, might lead 

to an electrical short circuit and generation 

of smoke, possibly affecting operation of 

systems and resulting in reduced control of 

the aeroplane. 

To address this potential unsafe condition, 

Dassault Aviation issued [service bulletin] SB 

F50–530, providing instructions for 

installation of a protective plate on the 

electrical wiring. 

For the reasons described above, this 

[EASA] AD requires modification of the 

aeroplane by installing a protective plate on 

the electrical wiring. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0527. 

Relevant Service Information 

Dassault has issued Service Bulletin 

F50–530, dated November 12, 2013. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

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 and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Contacting the Manufacturer’’ 

Paragraph in This Proposed AD 

Since late 2006, we have included a 

standard paragraph titled ‘‘Airworthy 

Product’’ in all MCAI ADs in which the 

FAA develops an AD based on a foreign 

authority’s AD.
