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 A300 series airplanes, 

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). This proposed AD was 

prompted by a report of chafing found 

on the overflow sensor harness of the 

surge tank, and subsequent contact 

between the electrical wiring and fuel 

tank structure. This proposed AD would 

require a one-time inspection for 

chafing of the overflow sensor harness 

and structural damage of the outer tank, 

and repair if necessary. This proposed 

AD would also require modification of 

the sensor harness. We are proposing 

this AD to prevent chafing of the 

harness and subsequent contact between 

the electrical wiring and fuel tank 

structure, which could result in 

electrical arcing and a fuel tank 

explosion and consequent loss of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by May 23, 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 2013–0193, 

dated August 23, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Airbus Model A300 series 

airplanes, 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). The MCAI 

states: 

During a scheduled maintenance check on 

an A300 aeroplane, chafing was found on the 

surge tank overflow sensor harness. The 

harness was found to contact the Magnetic 

Fuel Level Indicator (MFLI) canister. 

Prompted by these findings, DGAC 

[Direction Ge ́ne ́rale de l’Aviation Civile] 

France issued http://ad.easa.europa.eu/blob/ 

easa_ad_1999_404_293.pdf/AD_1999-404- 

293 to require modification of the harness 

routing in accordance with the instructions 

of Airbus SB [service bulletin] A300–28– 

0058 or SB A300–28–6020, as applicable to 

aeroplane model. 

Since that [DGAC] AD was issued, 

maintenance work on modified A300–600 

aeroplanes revealed some chafing of the 

harness, creating a potential contact between 

the electrical wire and fuel tank structure. 

Investigations have shown that although 

measures were taken to prevent contact of the 

harness with the MFLI (through modification 

04489),the installation can be subject to 

human error. As the MFLI is integral to the 

access panel in this location, any potential 

contact with the harness (as a result of 

incorrect installation) is hidden. 

This condition, if not detected and 

corrected, could lead to electrical arcing, 

possibly resulting in a fuel tank explosion 

and loss of the aeroplane. To address this 

potential unsafe condition, Airbus issued SB 

A300–28–0091 for A300 aeroplanes, SB 

A300–28–6109 for A300–600 aeroplanes, and 

A300–28–9022 for A300–600ST aeroplanes. 

For the reasons described above, this 

[EASA] AD requires a one-time inspection of 

the harness and, depending on findings, 

corrective actions, as well as replacement of 

angle brackets by error-proof harness 

brackets. 

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– 

2014–0189. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletins A300–28–0091, dated March 

5, 2013; and A300–28–6109, Revision 

01, dated December 20, 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. 

Repair Approvals 

In many FAA transport ADs, when 

the service information specifies to 

contact the manufacturer for further 

instructions if certain discrepancies are 

found, we typically include in the AD 

a requirement to accomplish the action 

using a method approved by either the 

FAA or the State of Design Authority (or 

its delegated agent). 

We have recently been notified that 

certain laws in other countries do not 

allow such delegation of authority, but 

some countries do recognize design 

approval organizations. In addition, we 

have become aware that some U.S. 

operators have used repair instructions 

that were previously approved by a 

State of Design Authority or a Design 

Approval Holder (DAH) as a method of 

compliance with this provision in FAA 

ADs. Frequently, in these cases, the 

previously approved repair instructions 

come from the airplane structural repair 

manual or the DAH repair approval 

statements that were not specifically 

developed to address the unsafe 

condition corrected by the AD. Using 

repair instructions that were not 

specifically approved for a particular 

AD creates the potential for doing 

repairs that were not developed to 

address the unsafe condition identified 

by the MCAI AD, the FAA AD, or the 

applicable service information, which 

could result in the unsafe condition not 

being fully corrected. 

To prevent the use of repairs that 

were not specifically developed to 

correct the unsafe condition, certain 

requirements of this proposed AD 


rmajette on DSK2TPTVN1PROD with PROPOSALS
19298 Federal Register / Vol. 79, No. 67 / Tuesday, April 8, 2014 / Proposed Rules 

specify that the repair approval 

specifically refer to the FAA AD. This 

change is 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 use the phrase ‘‘its 

delegated agent, or the DAH with State 

of Design Authority design organization 

approval, as applicable’’ in this 

proposed AD to refer to a DAH 

authorized to approve certain required 

repairs for this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 123 airplanes of U.S. registry. 

We also estimate that it would take 

about 3 work-hours per product to 

comply with the inspection required by 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of 

this inspection proposed by this AD on 

U.S. operators to be $31,365, or $255 per 

product. 

We estimate that it would take about 

12 work-hours per product to comply 

with the modification requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $500 per 

product. Based on these figures, we 

estimate the cost of this modification 

proposed by this AD on U.S. operators 

to be $186,960, or $1,520 per product. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition repairs 

specified in this proposed AD. 

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.

Federal Aviation Administration 

14 CFR Part 39

Identifier 2013–NM–157–AD]

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 reports of two in-service 

incidents where one side of the main 

landing gear (MLG) did not achieve 

down-lock. This proposed AD would 

require a detailed inspection of the apex 

joints of the stabilizer brace lock link in 

the MLG for clearance; rectifying and 

repairing the clearance gap, if necessary; 

and lubricating the apex joints of the 

stabilizer brace lock link in the MLG. 

We are proposing this AD to detect and 

correct insufficiently greased stabilizer 

brace lock linkage of the MLG and overtorqued lock linkage attachment bolts, 

which could lead to the failure to 

extend and down-lock the MLG, and 

could affect the safe landing of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by May 23, 2014. 

ADDRESSES: You may send comments by 

any of the following methods:
