The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

Empresa Brasileira de Aeronautica S.A. 

(EMBRAER): Docket No. FAA–2007–

27981; Directorate Identifier 2007–NM–

021–AD. 

Comments Due Date 

(a) We must receive comments by May 24, 

2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to EMBRAER Model 

EMB–145XR airplanes; certificated in any 

category; as identified in EMBRAER Service 

Bulletin 145–28–0026, dated May 16, 2006. 

Subject 

(d) Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

It has been found that the refueling line 

inside the ventral fuel tank on the Embraer 

EMB–145XR aircraft model is not protected 

in accordance with SFAR–88 (Special 

Federal Aviation Regulation 88) 

requirements. 

The unsafe condition is potential ignition 

sources inside fuel tanks, which, in 

combination with flammable fuel vapors, 

could result in fuel tank explosions and 

consequent loss of the airplane. The MCAI 

requires installation of a bonding jumper 

between the pilot valve line tube and the 

pressure refueling system tube. 

Actions and Compliance 

(f) At the time specified in paragraphs (f)(1) 

and (f)(2) of this AD, unless already done, 

install a bonding jumper between the pilot 

valve line tube and the pressure refueling 

system tube, after removing ventral fuel tank 

access panel 196FR, as described in 

EMBRAER Service Bulletin 145–28–0026, 

dated May 16, 2006. 

(1) For airplanes that have accumulated 

less than 5,000 total flight hours as of the 

effective date of this AD: Prior to the 

accumulation of 10,000 total flight hours. 

(2) For airplanes that have accumulated 

5,000 or more total flight hours as of the 

effective date of this AD: Within 5,000 flight 

hours after the effective date of this AD.

Airworthiness Directives; Avions 

Marcel Dassault-Breguet Model Falcon 

10 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) that applies to all 

Dassault Model Falcon 10 series 

airplanes. The existing AD currently 

requires revising the airplane flight 

manual (AFM) and installing a placard 

in the flight deck to prohibit flight into 

known or forecasted icing conditions. In 

lieu of the AFM revision and placard 

installation, that AD allows identifying 

the part number of each flexible hose in 

the wing (slat) anti-icing system, 

performing repetitive inspections of 

each hose for delamination, and 

performing corrective actions if 

necessary. That AD allows the following 

actions (also in lieu of the AFM revision 

and placard installation): new repetitive 

inspections for delamination at reduced 

intervals, corrective actions if necessary, 

and an additional AFM revision to 

include a statement to track flight cycles 

when the slat anti-icing system is 

activated. That AD also provides 

optional terminating action for the 

repetitive inspection requirements. This 

proposed AD would mandate the 

previously optional terminating action. 

This proposed AD results from a report 

of in-service delamination of a flexible 

hose in the slat anti-icing system at a 

time earlier than previously reported. 

We are proposing this AD to prevent 

collapse of the flexible hoses in the slat 

anti-icing system, which could lead to 

insufficient anti-icing capability and, if 

icing is encountered in this situation, 

could result in reduced controllability 

of the airplane. 

DATES: We must receive comments on 

this proposed AD by May 24, 2007. 

ADDRESSES: Use one of the following

proposed AD.

Discussion 

On August 26, 2005, we issued AD 

2005–18–14, amendment 39–14254 (70 

FR 53540, September 9, 2005), for all 

Dassault Model Falcon 10 series 

airplanes. That AD requires revising the 

airplane flight manual (AFM) and 

installing a placard in the flight deck to 

prohibit flight into known or forecasted 

icing conditions. In lieu of the AFM 

revision and placard installation, that 

AD allows identifying the part number 

(P/N) of each flexible hose in the wing 

(slat) anti-icing system, performing 

repetitive inspections of each hose for 

delamination, and performing corrective 

actions if necessary. That AD allows the 

following actions (also in lieu of the 

AFM revision and placard installation): 

new repetitive inspections for 

delamination at reduced intervals, 

corrective actions if necessary, and an 

additional AFM revision to include a 

statement to track flight cycles when the 

slat anti-icing system is activated. That 

AD also provides an option to 

repetitively replace the existing flexible 

hoses with improved flexible hoses, 

which terminates the repetitive 

inspection requirements. That AD 

resulted from a report of in-service 

delamination of a flexible hose in the 

slat anti-icing system at a time earlier 

than previously reported. We issued 

that AD to prevent collapse of the 

flexible hoses in the slat anti-icing 

system, which could lead to insufficient 

anti-icing capability and, if icing is 

encountered in this situation, could 

result in reduced controllability of the 

airplane. 

Actions Since Existing AD Was Issued 

The preamble to AD 2005–18–14 

explains that we considered the 

requirements ‘‘interim action’’ and were 

considering further rulemaking. The 

European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has since mandated the 

previously optional terminating action. 

We now have determined that further 

rulemaking is indeed necessary. This 

proposed AD follows from that 

determination. 

Relevant Service Information 

AD 2005–18–14 refers to Dassault 

Service Bulletin F10–313, dated August 

10, 2005, as the appropriate source of 

service information for the optional 

terminating action. The manufacturer 

has since revised the service bulletin. 

Revision 1, dated May 10, 2006, advises 

of revised related maintenance 

documents and revised life limits for 

hoses having P/N FAL1007. The 

procedures in Revision 1 are the same 

as those in the original version of the 

service bulletin. Accomplishing the 

actions specified in the service 

information is intended to adequately 

address the unsafe condition. The EASA 

mandated the service information and 

issued EASA airworthiness directive 

2006–0114, dated May 10, 2006, to 

ensure the continued airworthiness of 

these airplanes in the European Union. 

FAA’s Determination and Requirements 

of the Proposed AD 

These airplanes are manufactured in 

France and are 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. As described 

in FAA Order 8100.14A, ‘‘Interim 

Procedures for Working with the 

European Community on Airworthiness 

Certification and Continued 

Airworthiness,’’ dated August 12, 2005, 

the EASA has kept the FAA informed of 

the situation described above. We have 

examined the EASA’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. 

This proposed AD would supersede 

AD 2005–18–14. This proposed AD 

would retain the existing requirements 

except the requirement to report 

inspection results, and mandate the 

previously optional terminating action. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with this proposed AD, at an 

average hourly labor rate of $80.

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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

It has been determined that the surface 

roughness of the wing stub safety walks 

Series 300, gray color (equals sandpaper grid 

40), installed during production on some 

aeroplane S/Ns, adversely affects the aircraft 

single engine climb performance. 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 24, 2007. 

ADDRESSES: You may send comments by 

any of the following methods:

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
