AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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) 

issued 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 some stringer 

reinforcements (F900DX) and some 

rivets (F900DX/F2000EX) missing from 

the skin panels on each side of the 

fuselage between frames 9 and 10 on 

certain Falcon 900DX and Falcon 

2000EX EASy aircraft; this situation 

affects the structural integrity of the 

fuselage. 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 14, 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 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This proposed AD references the 

MCAI and related service information 

that we considered in forming the 

engineering basis to correct the unsafe 

condition. The proposed AD contains 

text copied from the MCAI and for this 

reason might not follow our plain 

language principles. 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–27849; Directorate Identifier 

2006–NM–249–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal 

information you provide. We will also 

post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency Airworthiness Directive 

2006–0320–E, dated October 18, 2006 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states 

that following the incorporation of a 

design change to the Karman fairing, it 

has been determined that some stringer 

reinforcements (F900DX) and some 

rivets (F900DX/F2000EX) are missing 

from the skin panels on each side of the 

fuselage between frames 9 and 10 on 

certain Falcon 900DX and Falcon 

2000EX EASy aircraft. This situation 

affects the structural integrity of the 

fuselage and may lead to an unsafe 

condition if left uncorrected. The MCAI 

was issued to recover the certificated 

structural strength by adding the 

missing rivets and checking the 

condition of the adjacent structure, and 

to add the missing stringer caps on 

F900DX (as appropriate). These actions 

include inspecting the area, including 

holes and structure, where missing 

rivets are found, and contacting the 

manufacturer if the holes are out-ofround beyond tolerance, or if cracks are 

found, as applicable. 

Relevant Service Information 

Dassault has issued Service Bulletin 

F900EX–308, dated October 18, 2006, 

and Service Bulletin Falcon F2000EX–

133, dated September 28, 2006. 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 Proposed 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, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information provided by the State of 

Design Authority and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

Differences Between This 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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

described in a separate paragraph of the 

proposed AD. These requirements, if 

ultimately adopted, will take 

precedence over the actions copied from 

the MCAI. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 2 products of U.S. registry. 

We also estimate that it would take 

about 170 work-hours per product to 

comply with this proposed AD. The 

average labor rate is $80 per work-hour. 

Required parts would cost $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these costs. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$27,200, or $13,600 per product. 

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 


rmajette on PROD1PC67 with PROPOSALS
Federal Register / Vol. 72, No. 70 / Thursday, April 12, 2007 / Proposed Rules 18417 

products identified in this rulemaking 

action. 

Regulatory Findings 

We 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 this 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

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: 

Dassault Aviation: Docket No. FAA–2007–

27849; Directorate Identifier 2006–NM–

249–AD. 

Comments Due Date 

(a) We must receive comments by May 14, 

2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault Model 

Falcon 2000EX airplanes, S/N (serial 

number) 82; and Falcon 900EX (version 

F900DX) airplanes, S/Ns 601 through 605; 

certificated in any category. 

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) states that 

following the incorporation of a design 

change to the Karman fairing, it has been 

determined that some stringer reinforcements 

(F900DX) and some rivets (F900DX/ 

F2000EX) are missing from the skin panels 

on each side of the fuselage between frames 

9 and 10 on certain Falcon 900DX and Falcon 

2000EX EASy aircraft. This situation affects 

the structural integrity of the fuselage and 

may lead to an unsafe condition if left 

uncorrected. The MCAI was issued to recover 

the certificated structural strength by adding 

the missing rivets and checking the condition 

of the adjacent structure, and to add the 

missing stringer caps on F900DX (as 

appropriate). These actions include 

inspecting the area, including holes and 

structure, where missing rivets are found, 

and contacting the manufacturer if the holes 

are out-of-round beyond tolerance, or if 

cracks are found, as applicable. 

Actions and Compliance 

(e) Within 3 months after the effective date 

of this AD, unless already done, do the 

following actions: Inspect and repair the 

aircraft in accordance with the instructions of 

Dassault Service Bulletin F900EX–308, dated 

October 18, 2006, for version F900DX, S/N 

601 through 605; and Dassault Service 

Bulletin F2000EX–133, dated September 28, 

2006, for Model F2000EX S/N 82. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: No 

differences.
