Airworthiness Directives; Airbus Model 

A320–111, –211, –212, and –231 

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 A320–111, –211, –212, 

and –231 airplanes. This AD requires, 

for certain airplanes, modifying the 

cables and access holes to the inner tank 

fuel pumps; and, for certain other 

airplanes, inspecting the fuel pump 

access holes and modifying the access 

holes, if necessary. This AD results from 

fuel system reviews conducted by the 

manufacturer. We are issuing this AD to 

prevent chafing of the fuel pump cables, 

which could result in electrical arcing 

and possible ignition of fuel vapors and 

consequent explosion of the fuel tank. 

DATES: This AD becomes effective 

November 30, 2005. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 30, 2005.

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 A320–

111, –211, –212, and –231 airplanes. 

That NPRM was published in the 

Federal Register on August 23, 2005 (70 

FR 49213). That NPRM proposed to 

require, for certain airplanes, modifying 

the cables and access holes to the inner 

tank fuel pumps; and, for certain other 

airplanes, inspecting the fuel pump 

access holes and modifying the access 

holes, if necessary. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment received. The 

commenter supports the NPRM. 

Clarification of Alternative Method of 

Compliance (AMOC) Paragraph 

We have revised this action to clarify 

the appropriate procedure for notifying 

the principal inspector before using any 

approved AMOC on any airplane to 

which the AMOC applies. 

Editorial Change 

As stated in the ‘‘Relevant Service 

Information’’ section of the NPRM, 

Airbus Service Bulletin A320–28–1054, 

dated August 23, 1993, describes 

procedures for performing an 

inspection, and ‘‘as applicable, 

modifying the fuel pump access holes.’’

We have revised paragraph (f)(2) of the 

final rule to state ‘‘* * * modify the 

access holes, as applicable * * *’’

instead of ‘‘* * * modify the access 

holes, as necessary * * *.’’

Conclusion 

We have carefully reviewed the 

available data, including the comment 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

This AD will affect about 17 airplanes 

of U.S. registry. The actions will be 

performed at an average labor rate of 

$65 per work hour, and any needed 

parts will be supplied from operator 

inventory. 

For about 7 U.S.-registered airplanes 

subject to Airbus Service Bulletin 

A320–28–1008, Revision 1, dated April 

10, 1989, the modification will take 

about 3 work hours. Based on these 

figures, the estimated cost of this 

modification for U.S. operators is 

$1,365, or $195 per airplane. 

For about 10 U.S.-registered airplanes 

subject to Airbus Service Bulletin 

A320–28–1054, dated August 23, 1993, 

the inspection will take about 1 work 

hour. Based on these figures, the 

estimated cost of this inspection for U.S. 

operators is $650, or $65 per airplane. 

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; 

Federal Register / Vol. 70, No. 206 / Wednesday, October 26, 2005 / Rules and Regulations 61721 

(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.

28–1054, dated August 23, 1993. Do any 

applicable repairs before further flight. 

Note 1: For the purposes of this AD, a 

general visual inspection is: ‘‘A visual 

examination of an interior or exterior area, 

installation, or assembly to detect obvious 

damage, failure, or irregularity. This level of 

inspection is made from within touching 

distance unless otherwise specified. A mirror 

may be necessary to ensure visual access to 

all surfaces in the inspection area. This level 

of inspection is made under normally 

available lighting conditions such as 

daylight, hangar lighting, flashlight, or 

droplight and may require removal or 

opening of access panels or doors. Stands, 

ladders, or platforms may be required to gain 

proximity to the area being checked.’’

No Reporting Requirement 

(g) Although Airbus Service Bulletin 

A320–28–1054, dated August 23, 1993, 

describes procedures for reporting inspection 

findings to Airbus, this AD does not require 

that report. 

Alternative Methods of Compliance 

(AMOCs)
