Airworthiness Directives; Airbus Model 

A300 B4–620, A310–304, A310–324, 

and A310–325 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A300 B4–620, A310–304, 

A310–324, and A310–325 airplanes. 

This AD requires installing fused 

adaptors between the external wiring 

harness and the in-tank wiring at the 

connectors on the fuel tank wall of the 

auxiliary center tank (ACT). This AD 

results from fuel system reviews 

conducted by the manufacturer. We are 

issuing this AD to prevent an ignition 

source in the ACT, which, in 

combination with flammable fuel 

vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 

DATES: This AD becomes effective 

November 10, 2005. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 10, 2005. 

ADDRESSES: You may examine the AD 

docket on the Internet at http:// 

dms.dot.gov or in person at the Docket

of Transportation, 400 Seventh Street

SUPPLEMENTARY INFORMATION: 

Examining the Docket 

You may examine the airworthiness 

directive (AD) docket on the Internet at 

http://dms.dot.gov or in person at the 

Docket Management Facility office 

between 9 a.m. and 5 p.m., Monday 

through Friday, except Federal holidays. 

The Docket Management Facility office 

(telephone (800) 647–5227) is located on 

the plaza level of the Nassif Building at 

the street address stated in the 

ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to certain Airbus Model A300 B4–

620, A310–304, A310–324, and A310–

325 airplanes. That NPRM was 

published in the Federal Register on 

August 8, 2005 (70 FR 45587). That 

NPRM proposed to require installing 

fused adaptors between the external 

wiring harness and the in-tank wiring at 

the connectors on the fuel tank wall of 

the auxiliary center tank (ACT). 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Clarification of Alternative Method of 

Compliance (AMOC) Paragraph 

We have revised this AD to clarify the 

appropriate procedure for notifying the 

principal inspector before using any 

approved AMOC on any airplane to 

which the AMOC applies. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD with the change 

described previously. We have 

determined that this change will neither 

increase the economic burden on any 

operator nor increase the scope of the 

AD. 

Costs of Compliance 

This AD affects about 2 airplanes of 

U.S. registry. The actions take about 52 

work hours per airplane, at an average 

labor rate of $65 per work hour. 

Required parts cost about $5,410 per 

ACT (up to two ACTs per airplane). 

Based on these figures, the estimated 

cost of the AD for U.S. operators is 

$8,790 per ACT, per airplane. 

Currently, there are no Model A300 

B4–620 airplanes of U.S. registry with 

one or more ACTs. However, if an 

affected airplane is imported and placed 

on the U.S. Register in the future, the 

required actions would take about 52 

work hours, at an average labor rate of 

$65 per work hour. Required parts 

would cost about $10,730 per ACT, per 

airplane. Based on these figures, we 

58304 Federal Register / Vol. 70, No. 193 / Thursday, October 6, 2005 / Rules and Regulations 

estimate the cost of this AD to be 

$14,110 per ACT. 

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 have 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 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

■ 2. The Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD): 

2005–20–14 Airbus: Amendment 39–14308. 

Docket No. FAA–2005–22032; 

Directorate Identifier 2005–NM–049–AD. 

Effective Date 

(a) This AD becomes effective November 

10, 2005.

Unsafe Condition 

(d) This AD is prompted by the results of 

fuel system reviews conducted by the

prevent an ignition source in the ACT, 

which, in combination with flammable fuel 

vapors, could result in a fuel tank explosion 

and consequent loss of the airplane.
