sessions of Congress, the effective date 

of the regulations is March 31, 2007.

Airworthiness Directives; Airbus Model 

A318, A319, A320, and A321 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to certain Airbus Model 

A318–100, A319–100, A320–200, A321–

100, and A321–200 series airplanes; and 

Model A320–111 airplanes. That AD 

currently requires modification of the 

electrical bonding of all structures and 

systems installed inside the center fuel 

tank. This new AD requires 

modification of additional bonding 

points inside the center fuel tank. This 

AD results from a report that additional 

bonding points need to be modified in 

order to prevent electrical arcing in the 

center fuel tank. We are issuing this AD 

to prevent electrical arcing in the center 

fuel tank due to inadequate bonding, 

which could result in an explosion of 

the center fuel tank and consequent loss 

of the airplane. 

DATES: This AD becomes effective May 

8, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of May 8, 2007. 

On October 26, 2005 (70 FR 55228, 

September 21, 2005), the Director of the 

Federal Register approved the 

incorporation by reference of Airbus 

Service Bulletin A320–28–1104, 

Revision 01, dated December 8, 2004.

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.

(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 

supersedes AD 2005–19–14, amendment 

39–14279 (70 FR 55228, September 21, 

2005). The existing AD applies to 

certain Airbus Model A318–100, A319–

100, A320–200, A321–100, and A321–

200 series airplanes; and Model A320–

111 airplanes. That NPRM was 

published in the Federal Register on 

January 12, 2007 (72 FR 1467). That 

NPRM proposed to continue to require 

modification of the electrical bonding of 

all structures and systems installed 

inside the center fuel tank. That NPRM 

also proposed to require modification of 

additional bonding points inside the 

center fuel tank. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the NPRM or on 

the determination of the cost to the 

public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with this AD. There are 

approximately 720 U.S.-registered 

airplanes. The average labor rate is $80 

per work hour.

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 removing amendment 39–14279 (70 

FR 55228, September 21, 2005) and by 

adding the following new airworthiness 

directive (AD): 

2007–07–09 Airbus: Amendment 39–15006. 

FAA–2007–26812; Directorate Identifier 

2006–NM–199–AD.

Unsafe Condition 

(d) This AD results from a report that 

additional bonding points need to be 

modified in order to prevent electrical arcing 

in the center fuel tank. We are issuing this 

AD to prevent electrical arcing in the center 

fuel tank due to inadequate bonding, which 

could result in an explosion of the center fuel 

tank and consequent loss of the airplane.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

EMBRAER Model ERJ 170 airplanes. 

This AD requires replacing the minilatches on certain lavatory waste 

compartment doors with new, stronger 

latches, and other specified actions. 

This AD results from reports of certain 

lavatory waste compartment doors 

opening during flight due to movement 

of the waste compartment during 

takeoff, because the mini-latches 

installed on the doors of those 

compartments lose their strength over 

time. We are issuing this AD to prevent 

the inability of the waste compartment 

doors to adequately contain a fire inside 

the lavatory waste compartment, and 

consequent uncontained fire and smoke 

within a lavatory during flight. 

DATES: This AD becomes effective May 

8, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 8, 2007.

Discussion 

The FAA issued a supplemental 

notice of proposed rulemaking (NPRM) 

to amend 14 CFR part 39 to include an 

AD that would apply to certain 

EMBRAER Model ERJ 170 airplanes. 

That supplemental NPRM was 

published in the Federal Register on 

January 26, 2007 (72 FR 3761). That 

supplemental NPRM proposed to 

require replacing the mini-latches on 

certain lavatory waste compartment 

doors with new, stronger latches, and 

other specified actions. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the supplemental 

NPRM or on the determination of the 

cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed in the 

supplemental NPRM. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with this AD.
