Airworthiness Directives; Dassault-Aviation Model FALCON 7X 
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:

    A design review has revealed a potential dormant failure of the 
Ram Air Turbine (RAT) heating system. If this failure occurs, it 
could lead to the freezing of the RAT mechanism and the consequent 
non-deployment of the RAT when needed.
* * * * *

Non-deployment of the RAT could result in insufficient electrical power 
to operate the fly-by-wire system, and

[[Page 481]]

subsequent loss of control of the airplane. 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 February 22, 
2011.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2010-0033, dated March 3, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    A design review has revealed a potential dormant failure of the 
Ram Air Turbine (RAT) heating system. If this failure occurs, it 
could lead to the freezing of the RAT mechanism and the consequent 
non-deployment of the RAT when needed.

    The purpose of this AD is to require a repetitive functional 
test of the RAT heater * * *.

Non-deployment of the RAT could result in insufficient electrical power 
to operate the fly-by-wire system, and subsequent loss of control of 
the airplane. The corrective action is repairing using a method 
approved by either the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA; or the European Aviation Safety 
Agency (EASA) (or its delegated agent). You may obtain further 
information by examining the MCAI in the AD docket.

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 21 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $1,785, or $85 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-2010-1306; Directorate Identifier 
2010-NM-112-AD.

Comments Due Date

    (a) We must receive comments by February 22, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Dassault-Aviation Model FALCON 7X 
airplanes, certificated in any category, all serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 24: 
Electrical power.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    A design review has revealed a potential dormant failure of the 
Ram Air Turbine (RAT) heating system. If this failure occurs, it 
could lead to the freezing of the RAT mechanism and the consequent 
non-deployment of the RAT when needed.
* * * * *
Non-deployment of the RAT could result in insufficient electrical 
power to operate the fly-by-wire system, and subsequent loss of 
control of the airplane.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Actions

    (g) At the applicable times specified in paragraph (g)(1) or 
(g)(2) of this AD, do a functional test of the RAT heater using a 
method approved by either the Manager, International Branch, ANM-
116, Transport Airplane Directorate, FAA; or the European Aviation 
Safety Agency (EASA) (or its delegated agent). Repeat the functional 
test of the RAT heater thereafter at the applicable time specified 
in paragraph (g)(1) or (g)(2) of this AD. If any functional test 
fails, before further flight, repair using a method approved by 
either the Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA; or EASA (or its delegated agent).
    (1) For Falcon 7X airplanes on which modification M0305 has not 
been done and on which Dassault Service Bulletin 7X-018, dated March 
6, 2009, has not been done: Within 650 flight hours after the 
effective date of this AD, do a functional test of the RAT heater 
and repeat the functional test of the RAT heater thereafter at 
intervals not to exceed 650 flight hours.
    (2) For Falcon 7X airplanes on which modification M0305 has been 
done or on which Dassault Service Bulletin 7X-018, dated March 6, 
2009, has been done: Within 1,900 flight hours after the effective 
date of this AD or after modification M0305 or Dassault Service 
Bulletin 7X-018, dated March 6, 2009, has been done, whichever 
occurs later, do a functional test of the RAT heater: Repeat the 
functional test of the RAT heater thereafter at intervals not to 
exceed 1,900 flight hours.

    Note 1: Additional guidance for doing the functional test of the 
RAT heater required by paragraph (g) of this AD can be found in Task 
24-50-25-720-801, Functional Test of the RAT Heater, dated January 
16, 2009, of the Dassault Falcon 7X Aircraft Maintenance Manual 
(AMM).

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows:
    (1) The MCAI provides an option of inserting the MCAI into the 
Falcon 7X AMM Chapter 5-40, pending publication of the revised AMM 
Chapter 5-40. This AD does not have that option.
    (2) The MCAI requires doing the actions in accordance with 
Maintenance Task 24-50-25-720-801, Chapter 5-40, of the Dassault 
Falcon 7X AMM. However, this AD requires that the actions be done 
using a method approved by the FAA or EASA (or its delegated agent).

Other FAA AD Provisions

    (h) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. Send information to ATTN: Tom Rodriguez, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone 
(425) 227-1137; fax (425) 227-1149. Before using any approved AMOC 
on any airplane to which the AMOC applies, notify your principal 
maintenance inspector (PMI) or principal avionics inspector (PAI), 
as appropriate, or lacking a principal inspector, your local Flight 
Standards District Office. The AMOC approval letter must 
specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: A Federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5 
minutes per response, including the time for reviewing instructions, 
completing and reviewing the collection of information. All 
responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing 
the burden should be directed to the FAA at: 800 Independence Ave., 
SW., Washington, DC 20591, Attn: Information Collection Clearance 
Officer, AES-200.
