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.

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; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Due to quality escape during serial 

production, the jumpers at the Right Fuel 

Standby Pump Connector 4Q1 were 

manufactured from 14 AWG electrical wiring 

instead of 12 AWG wires as required per 

approved drawing. The possible overheating 

of the 14 AWG jumpers routed in vicinity of 

the fuel tank may present the unsafe flight 

condition. 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective April 

18, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication, listed in the AD 

as of April 18, 2007. 

We must receive comments on this 

AD by May 3, 2007.

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. This streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This AD references the MCAI and 

related service information that we 

considered in forming the engineering 

basis to correct the unsafe condition. 

The AD contains text copied from the 

MCAI and for this reason might not 

follow our plain language principles. 

Discussion 

The Civil Aviation Authority of Israel 

(CAAI), which is the aviation authority 

for Israel, has issued Israeli 

Airworthiness Directive 28–07–02–03, 

dated February 11, 2007 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Due to quality escape during serial 

production, the jumpers at the Right Fuel 

Standby Pump Connector 4Q1 were 

manufactured from 14 AWG electrical wiring 

instead of 12 AWG wires as required per 

approved drawing. The possible overheating 

of the 14 AWG jumpers routed in vicinity of 

the fuel tank may present the unsafe flight 

condition. 

The corrective actions include 

replacing the wiring, inspecting for 

other components damaged by 

overheating, and replacing damaged 

components if necessary. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Relevant Service Information 

Gulfstream has issued Alert Service 

Bulletin 200–28A–315, dated February 

5, 2007. 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 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 issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between the AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice
