Airworthiness Directives; Dassault Model Falcon 2000 Airplanes 
Equipped With CFE Company CFE738-1-1B Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Dassault Model Falcon 2000 airplanes equipped with CFE 
Company CFE738-1-1B turbofan engines. This proposed AD would require 
determining the serial number of the engines installed on the airplane, 
inspecting any affected engine to verify that a spherical bearing is 
installed on the attachment fitting of the engine mount, and corrective 
action if necessary. This proposed AD results from a report of a 
missing spherical bearing on the attachment fitting of the front engine 
mount on an in-service airplane, and subsequent damage and abnormal 
fatigue of the attachment fitting. We are proposing this AD to prevent 
reduced structural integrity of the engine mount, which could result in 
possible separation of an engine from the airplane.

DATES: We must receive comments on this proposed AD by October 31, 
2005.

Discussion

    The Direction Generale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, notified us that an unsafe 
condition may exist on certain Dassault Model Falcon 2000 airplanes 
equipped with CFE Company CFE738-1-1B turbofan engines. The DGAC 
advises that there has been a report of a missing spherical bearing 
found on the attachment fitting of the front engine mount on an in-
service airplane. The absence of the spherical bearing resulted in 
damage and abnormal fatigue of the attachment fitting. Investigation 
revealed that the missing spherical bearing was one intended for pickup 
of loads perpendicular to the engine thrust. After the engine was moved 
from the right-hand to the left-hand side of the airplane, the 
spherical bearing was found in the outer ring of the opposite side. 
Airplanes affected by this defect would be those on which one or both 
engines were moved from one side of the airplane to the other during 
production. This condition, if not corrected, could cause reduced 
structural integrity of the engine mount, which could result in 
possible separation of an engine from the airplane.

Relevant Service Information

    Dassault has issued Service Bulletin F2000-299, dated July 23, 
2004. The service bulletin describes procedures for determining the 
serial number of the engines installed on the airplane, performing a 
borescope inspection of any affected engine to verify a spherical 
bearing is installed on the attachment fitting of the front engine 
mount, and corrective action if necessary. If a spherical bearing is 
missing, the corrective action involves removing the engine and sending 
it to a CFE service center for repair. The DGAC mandated the service 
information and issued French airworthiness directive F-2004-128, dated 
August 4, 2004, to ensure the continued airworthiness of these 
airplanes in France.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in France 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 DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC'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, except as discussed under ``Differences Among 
Proposed AD, French Airworthiness Directive, and Service Bulletin.''

Differences Among Proposed AD, French Airworthiness Directive, and 
Service Bulletin

    The French airworthiness directive and the service bulletin specify 
that if a spherical bearing is missing, operators should return the 
engine to a CFE service center for repair. This proposed AD would 
require you to repair those conditions using a method that we or the 
DGAC (or its delegated agent) approve. In light of the type of repair 
that would be required to address the unsafe condition, and consistent 
with existing bilateral airworthiness agreements, we have determined 
that, for this proposed AD, a repair we or the DGAC approve would be 
acceptable for compliance with this proposed AD.
    Although the French airworthiness directive referenced in this AD 
specifies to submit certain information to the manufacturer, this 
proposed AD does not include that requirement.

Costs of Compliance

    This proposed inspection would affect about 7 airplanes of U.S. 
registry. The proposed inspection would take about 2 work hours per 
airplane, at an average labor rate of $65 per work hour. Based on these 
figures, the estimated cost of the proposed AD for U.S. operators is 
$910, or $130 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

[[Page 57219]]

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.
