AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42–500 airplanes, 

and Model ATR72–212A airplanes. This 

proposed AD was prompted by a report 

that during an inspection of an airplane 

on the production line, interference was 

detected between the electrical harness 

and a bonding lead due to an incorrect 

installation of the affected bonding lead. 

This proposed AD would require a 

detailed inspection for damage or 

incorrect routing of the bonding lead 

routing above the 120VU shelf, and if 

any damage or incorrect routing is 

found, modifying the bonding lead 

routing. We are proposing this AD to 

detect and correct installation of the 

bonding lead, which could cause arcing 

and chafing, and could possibly result 

in an uncontrolled fire. 

DATES: We must receive comments on 

this proposed AD by September 29, 

2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued Airworthiness 

Directive 2014–0056, dated March 7, 

2014 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for certain ATR— 

GIE Avions de Transport Re ́gional 

Model ATR42–500 airplanes, and Model 

ATR72–212A airplanes. The MCAI 

states: 

During inspection of an aeroplane on the 

production line, interference was detected 

between electrical harnesses (2M–2S–6M) 

and a bonding lead, located in zone 214, 

positioned above and forward of the 120VU 

shelf. Subsequent investigation revealed that 

the interference was a result of an incorrect 

installation of the affected bonding lead. 

This condition, if not detected and 

corrected, could lead to arcing and chafing, 

possibly resulting in an uncontrolled fire. 

To address this potential unsafe condition, 

ATR issued Service Bulletin (SB) ATR42–92– 

0025 and SB ATR72–92–1034, as applicable 

to aeroplane model, to provide inspection 

instructions. 

For the reasons described above, this 

[EASA] AD requires a one-time [detailed] 

inspection [for damage or incorrect routing of 

the bonding lead routing above the 120VU 

shelf] of the electrical harness 2M–2S–6M in 

zone 214 and, depending on findings, 

accomplishment of corrective action(s). 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0530. 

Relevant Service Information 

ATR—GIE Avions de Transport 

Re ́gional has issued ATR Service 

Bulletin ATR42–92–0025, dated 

November 7, 2013; and ATR Service 

Bulletin ATR72–92–1034, dated 

November 7, 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 these same 

type designs. 

‘‘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. 

The MCAI or referenced service 

information in an FAA AD often directs 

the owner/operator to contact the 

manufacturer for corrective actions, 

such as a repair. Briefly, the Airworthy 

Product paragraph allowed owners/

operators to use corrective actions 

provided by the manufacturer if those 

actions were FAA-approved. In 

addition, the paragraph stated that any 

actions approved by the State of Design 

Authority (or its delegated agent) are 

considered to be FAA-approved. 

In an NPRM having Directorate 

Identifier 2012–NM–101–AD (78 FR 

78285, December 26, 2013), we 

proposed to prevent the use of repairs 

that were not specifically developed to 

correct the unsafe condition, by 

requiring that the repair approval 

provided by the State of Design 

Authority or its delegated agent 

specifically refer to the FAA AD. This 

change was intended to clarify the 

method of compliance and to provide 

operators with better visibility of repairs 

that are specifically developed and 

approved to correct the unsafe 

condition. In addition, we proposed to 

change the phrase ‘‘its delegated agent’’ 

to include a design approval holder 

(DAH) with State of Design Authority 

design organization approval (DOA), as 

applicable, to refer to a DAH authorized 

to approve required repairs for the 

proposed AD. 

One commenter to the NPRM having 

Directorate Identifier 2012–NM–101–AD 

(78 FR 78285, December 26, 2013) stated 

the following: ‘‘The proposed wording, 

being specific to repairs, eliminates the 

interpretation that Airbus messages are 

acceptable for approving minor 

deviations (corrective actions) needed 

during accomplishment of an AD 

mandated Airbus service bulletin.’’ 

This comment has made the FAA 

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 AD-mandated 

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. 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
47392 Federal Register / Vol. 79, No. 156 / Wednesday, August 13, 2014 / Proposed Rules 

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 actions 

must be accomplished using a method 

approved by the FAA, the European 

Aviation Safety Agency (EASA), or 

ATR—GIE Avions de Transport 

Re ́gional’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. 

Costs of Compliance 

We estimate that this proposed AD 

affects 5 airplanes of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 

operators to be $850, or $170 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 2 work-hours and require parts 

costing $0, for a cost of $170 per 

product. We have no way of 

determining the number of aircraft that 

might need this action. 

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.

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier Inc. Model DHC–8–400 

series airplanes. This proposed AD was 

prompted by a report that during 

production, an incorrect clevis was 

used, resulting in improper installation 

onto the alternate release cable of the 

main landing gear (MLG). This proposed 

AD would require a detailed visual 

inspection of the emergency release 

clevis of the MLG to determine if an 

incorrect clevis has been installed, and 

if necessary, replacing the clevis with a 

correct clevis and clevis pin. We are 

proposing this AD to detect and correct 

improper installation of the clevis, 

which could cause loss of the alternate 

release system and prevent the MLG 

from extending and retracting, and 

could consequently affect the airplane’s 

continued safe flight and landing. 

DATES: We must receive comments on 

this proposed AD by September 29, 

2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR
