Airworthiness Directives; Dassault Model Falcon 2000 Airplanes

AGENCY: Federal Aviation Administration (FAA), 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) 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:

    In service events have shown that, after implementation of 
Dassault Aviation SB

[[Page 13512]]

F2000-133 and F2000-166, a risk of engine cowlings separation from 
the airplane still exists, and may cause potential damages to the 
engine itself and to the horizontal stabilizer.
    It is suspected that on-ground improper latching may lead to a 
radial deformation of engine cowlings in flight and to their 
eventual escape out of their locking devices. This situation may 
represent a hazard to the aircraft propulsive system and/or its 
structural integrity.

* * * * *
The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
Airworthiness Directive 2007-0016, dated January 12, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    In service events have shown that, after implementation of 
Dassault Aviation SB F2000-133 and F2000-166, a risk of engine 
cowlings separation from the airplane still exists, and may cause 
potential damages to the engine itself and to the horizontal 
stabilizer.
    It is suspected that on-ground improper latching may lead to a 
radial deformation of engine cowlings in flight and to their 
eventual escape out of their locking devices. This situation may 
represent a hazard to the aircraft propulsive system and/or its 
structural integrity.
    The purpose of this Airworthiness Directive (AD) is to secure 
safe closure of engine cowlings and improve the existing locking 
devices.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Dassault has issued Service Bulletins F2000-166, Revision 1, dated 
October 24, 2001, and F2000-298, Revision 3, dated September 26, 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 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, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an 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 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 229 products of U.S. registry. We also estimate that 
it would take about 90 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $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 $1,648,800, or $7,200 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 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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Dassault Aviation: Docket No. FAA-2008-0272; Directorate Identifier 
2007-NM-275-AD.

Comments Due Date

    (a) We must receive comments by April 14, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Dassault Model Falcon 2000 airplanes, 
certificated in any category, all serial numbers, except those that 
have incorporated Modification M2275 during production or Dassault 
Service Bulletin F2000-298 in service.

Subject

    (d) Air Transport Association (ATA) of America Code 54: 
Nacelles/Pylons.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    In service events have shown that, after implementation of 
Dassault Aviation SB F2000-133 and F2000-166, a risk of engine 
cowlings separation from the airplane still exists, and may cause 
potential damages to the engine itself and to the horizontal 
stabilizer.
    It is suspected that on-ground improper latching may lead to a 
radial deformation of engine cowlings in flight and to their 
eventual escape out of their locking devices. This situation may 
represent a hazard to the aircraft propulsive system and/or its 
structural integrity.
    The purpose of this Airworthiness Directive (AD) is to secure 
safe closure of engine cowlings and improve the existing locking 
devices.

Actions and Compliance

    (f) Within 12 months after the effective date of this AD unless 
already done, do the following actions.
    (1) Modify the existing engine cowls locking system in 
accordance with the instructions contained in Dassault Service 
Bulletin F2000-298, Revision 3, dated September 26, 2007.
    (2) Before or concurrent with the modification required by 
paragraph (f)(1) of this AD, modify the engine cowling attachments 
in accordance with the instructions contained in Dassault Service 
Bulletin F2000-166, Revision 1, dated October 24, 2001 (Modification 
M1579).
    (3) Actions done before the effective date of this AD in 
accordance with Dassault Service Bulletins F2000-298, Revision 1, 
dated October 31, 2006, or Revision 2, dated April 12, 2007; and 
F2000-166 dated June 27, 2001; are acceptable for compliance with 
the corresponding actions of this AD.
