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 A319–100 series 

airplanes, Model A320–111 airplanes, 

Model A320–200 series airplanes, and 

Model A321–100 series airplanes 

equipped with any additional center 

tank (ACT). This AD requires 

identifying the part number of the ACT 

and, for certain ACTs, replacing the 

outer ACT manhole cover and seal. This 

AD results from reports of an ACT fuel 

transfer failure due to air leakage around 

the seal of the outer manhole covers of 

the ACTs. We are issuing this AD to 

prevent this leakage, which could result 

in fuel or fuel vapor leaking into the 

cargo compartment, and consequent 

increased risk of a fire in the cargo 

compartment. 

DATES: This AD becomes effective 

December 19, 2005. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of December 19, 2005.

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 A319–

100 series airplanes, Model A320–111 

airplanes, Model A320–200 series 

69068 Federal Register / Vol. 70, No. 218 / Monday, November 14, 2005 / Rules and Regulations 

airplanes, and Model A321–100 series 

airplanes equipped with certain 

additional center tanks (ACT). That 

NPRM was published in the Federal 

Register on August 17, 2005 (70 FR 

48336). That NPRM proposed to require 

identifying the part number (P/N) of the 

ACT and, for certain ACTs, replacing 

the outer ACT manhole cover and seal. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the single comment 

received. The commenter supports the 

NPRM. 

Additional Service Bulletin Information 

After the NPRM was issued Airbus 

released Revision 02 of service bulletin 

A321–28–1105, dated March 11, 2005. 

We have reviewed it, and it is 

substantially similar to Revision 01, 

which was referred to in the NPRM as 

the acceptable source of service 

information. We have revised paragraph 

(g) of this AD to refer to Revision 02 of 

the service bulletin as the acceptable 

source of service information, and to 

give credit for doing Revision 01 before 

the effective date of this AD. 

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. 

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 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 

The following table provides the 

estimated costs for U.S. operators to 

comply with this 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 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.

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Learjet Model 23, 24, 24A, 24B, 24B–A, 

24C, 24D, 24D–A, 24E, 24F, 24F–A, 25, 

25A, 25B, 25C, 25D, and 25F airplanes. 

This AD requires replacement of the 

spherical accumulator for the main 

hydraulic system with a new cylindrical 

accumulator. For certain airplanes, this 

AD also requires modification of the 

accumulator pressure gauge. This AD 

results from reports of the failure of two 

thrust reverser accumulators (which are 

similar to the main hydraulic system’s 

spherical accumulator) and fatigue 

cracks found on four thrust reverser 

accumulators. We are issuing this AD to 

prevent failure of the spherical 

accumulator for the main hydraulic 

system, due to fatigue cracking on the 

threads, which could result in the loss 

of hydraulic power, damage to the 

surrounding airplane structure, and loss 

of airplane control. The failure of the 

accumulator could also result in injury 

to any persons in the surrounding area. 

The loss of hydraulic fluid could also 

leak onto a potential source of ignition 

and result in a consequent fire. 

DATES: This AD becomes effective 

December 19, 2005. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of December 19, 2005.

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 Learjet Model 23, 24, 

24A, 24B, 24B–A, 24C, 24D, 24D–A, 

24E, 24F, 24F–A, 25, 25A, 25B, 25C, 

25D, and 25F airplanes. That NPRM was 

published in the Federal Register on 

August 23, 2005 (70 FR 49210). That 

NPRM proposed to require replacement 

of the spherical accumulator for the 

main hydraulic system with a new 

cylindrical accumulator. For certain
