ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain EMBRAER Model ERJ 170 

airplanes. This proposed AD would 

require replacement of certain electrical 

bonding clamps and attaching hardware 

with new or serviceable parts, as 

applicable, and other specified action. 

This proposed AD results from failure of 

an electrical bonding clamp, used to 

attach the electrical bonding straps to 

the fuel system lines. We are proposing 

this AD to prevent loss of bonding 

protection in the interior of the fuel 

tanks or adjacent areas that, in 

combination with lightning strike, could 

result in a fuel tank explosion and 

consequent loss of the airplane. 

DATES: We must receive comments on 

this proposed AD by October 26, 2006. 

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.

Discussion 

The Ageˆncia Nacional de Aviac ̧a ̃o 

Civil (ANAC), which is the 

airworthiness authority for Brazil, 

notified us that an unsafe condition may 

exist on certain EMBRAER Model ERJ 

170 airplanes. The ANAC advises that 

an electrical bonding clamp, used to 

attach the electrical bonding straps to 

the fuel system lines, failed in one 

instance. Investigation revealed that a 

batch of electrical bonding clamps was 

manufactured with the incorrect 

material. These discrepant clamps were 

installed on several airplanes, which 

may lead to loss of bonding protection 

in the interior of the fuel tanks or 

adjacent areas. In combination with 

lightning strike, this condition, if not 

corrected, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 

Relevant Service Information 

EMBRAER has issued Service Bulletin 

170–28–0009, Revision 01, dated 

February 23, 2006. The service bulletin 

describes procedures for replacing all 

electrical bonding clamps having part 

number AN735D4 or AN735D6 with 

new parts and accomplishing the other 

specified action. The other specified 

action is an electrical bonding test of the 

reconnected strap. Accomplishing the 

actions specified in the service 

information is intended to adequately 

address the unsafe condition. The 

ANAC mandated the service 

information and issued Brazilian 

airworthiness directive 2006–06–03, 

effective July 7, 2006, to ensure the 

continued airworthiness of these 

airplanes in Brazil. 

FAA’s Determination and Requirements 

of the Proposed AD 

This airplane model is manufactured 

in Brazil and is type certificated for 

operation in the United States under the 

provisions of section 21.29 of the 

Federal Aviation Regulations (14 CFR 

21.29) and the applicable bilateral 

airworthiness agreement. Pursuant to 

this bilateral airworthiness agreement, 

the ANAC has kept the FAA informed 

of the situation described above. We 

have examined the ANAC’s findings, 

evaluated all pertinent information, and 

determined that we need to issue an AD 

for airplanes of this type design that are 

certificated for operation in the United 

States. 

Therefore, we are proposing this AD, 

which would require accomplishing the 

actions specified in the service 

information described previously. 

Costs of Compliance 

This proposed AD would affect about 

68 airplanes of U.S. registry. The 

proposed actions would take about 1 

work hour per airplane, at an average 

labor rate of $80 per work hour. 

Required parts would cost about $41 per 

airplane. Based on these figures, the 

estimated cost of the proposed AD for 

U.S. operators is $8,228, or $121 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 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would 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 the proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

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 proposed AD and placed it in the 

AD docket. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment

2. The Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD):

which the AMOC applies, notify the 

appropriate principal inspector in the FAA 

Flight Standards Certificate Holding District 

Office.

Airworthiness Directives; Boeing

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: The FAA is revising an earlier 

proposed airworthiness directive (AD) 

for certain Boeing Model 747 airplanes. 

The original NPRM would have 

required repetitive tests to detect hot air 

leaking from the trim air diffuser ducts 

or sidewall riser duct assemblies 

(collectively referred to in this proposed 

AD as ‘‘TADDs’’), related investigative 

actions, and corrective actions if 

necessary. The original NPRM also 

would have provided an optional 

terminating action for the repetitive 

tests. The original NPRM resulted from 

reports of sealant deteriorating on the 

outside of the center wing fuel tank and 

analysis that sealant may deteriorate 

inside the tank due to excess heat from 

leaking TADDs. This action revises the 

original NPRM by referring to improved 

inspection procedures and extending 

the repetitive interval for certain related 

investigative actions. We are proposing 

this supplemental NPRM to prevent 

leakage of fuel or fuel vapors into areas 

where ignition sources may be present, 

which could result in a fire or 

explosion. 

DATES: We must receive comments on 

this supplemental NPRM by October 23, 

2006.
