Airworthiness Directives; Avions Marcel Dassault-Breguet Model 
Falcon 10 Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding 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. This AD adds 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. This AD also provides an option to repetitively 
replace the existing flexible hoses with improved flexible hoses, which 
terminates the repetitive inspection requirements. This 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 
issuing 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: This AD becomes effective September 26, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 26, 
2005.
    On April 26, 2005 (70 FR 18282, April 11, 2005), the Director of 
the Federal Register approved the incorporation by reference of 
Dassault Alert Service Bulletin F10-A312, dated February 25, 2005, 
including the Service Bulletins Compliance Card.
    We must receive any comments on this AD by November 8, 2005.

SUPPLEMENTARY INFORMATION: 

Discussion

    On March 31, 2005, the FAA issued AD 2005-07-23, amendment 39-14048 
(70 FR 18282, April 11, 2005). That AD applies to all Dassault Model 
Falcon 10 series airplanes. That AD requires revising the Limitations 
section of the airplane flight manual (AFM) to include a statement 
prohibiting flight into known or forecasted icing conditions, and 
installing a placard in the flight deck. 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 detailed inspections of each hose for delamination, and 
performing corrective actions if necessary. That AD resulted from a 
report of delamination of the internal wall of a flexible hose in the 
slat anti-icing system. The actions specified in that AD are intended 
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 AD Was Issued

    Since we issued that AD the Direction G[eacute]n[eacute]rale de 
l'Aviation Civile (DGAC), which is the airworthiness authority for 
France, informed us of an in-service delamination of a flexible hose in 
the slat anti-icing system at a time earlier than previously reported.
    In addition, the preamble to AD 2005-07-23 explains that we 
consider the requirements ``interim action'' and were considering 
further rulemaking. We now have determined that further rulemaking is 
indeed necessary, and, although a final action has not yet been 
developed, this AD follows from that determination.

Relevant Service Information

    Avions Marcel Dassault-Breguet has issued Dassault Alert Service 
Bulletin F10-A312, Revision 1, dated June 27, 2005. The existing AD 
refers to Dassault Alert Service Bulletin F10-A312, dated February 25, 
2005, as the appropriate source of service information for 
accomplishing the required actions of that AD. Dassault Alert Service 
Bulletin F10-A312, Revision 1, describes procedures for a visual check 
and an improved boroscope inspection of the internal walls of each 
flexible hose in the slat anti-icing system for blistering 
(delamination), and performing corrective actions if necessary. The 
corrective actions include replacing any hose that doesn't have a 
certain part number with a hose having the part number specified in the 
service bulletin, and replacing any damaged hose with a new hose having 
the part number specified in the service bulletin. The DGAC mandated 
the service bulletin and issued French emergency airworthiness 
directive EASA.A.AD.01001, dated June 29, 2005, to ensure the continued 
airworthiness of these airplanes in France.
    Avions Marcel Dassault-Breguet has also issued Dassault Service 
Bulletin F10-313, dated August 10, 2005. This service bulletin 
describes procedures for replacing the existing flexible hoses with 
improved flexible hoses, having a new part number. These new flexible 
hoses have a temporary life limit of 90 flight cycles during which the 
slat anti-icing system is in use.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of This 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 products of this type design that are certificated for 
operation in the United States.
    Therefore, we are issuing this AD to supersede AD 2005-07-23. This 
new AD retains the requirements of the existing AD. This AD also:
     Provides an improved inspection method and reduces the 
intervals for the inspections;
     Provides an option to repetitively replace the existing 
flexible hoses with improved flexible hoses, which terminates the 
repetitive inspection requirements;
     Requires revising the Limitations section of the AFM to 
provide a mechanism for tracking flight cycles in which the slat anti-
icing system is activated; and
     Requires sending the inspection results to the 
manufacturer.

Differences Between the AD and the French Emergency Airworthiness 
Directive

    This AD differs from the French emergency airworthiness directive 
in that it includes the option to install improved flexible hoses. The 
airplane manufacturer is requesting that the DGAC approve this option 
as an alternative method of complying with French emergency 
airworthiness directive EASA.A.AD.01001.
    This AD also differs from the French emergency airworthiness 
directive by requiring an AFM revision to enable the tracking of flight 
cycles in which the slat anti-icing system is activated. The French 
emergency airworthiness directive contains instructions to the 
flightcrew to record in the flight log any time the anti-icing system 
switch is on during flight, but does not specify an AFM revision.
    These differences have been coordinated with the DGAC.

Interim Action

    This AD is considered to be interim action. The inspection reports 
that are required by this AD will enable the manufacturer to obtain 
better insight into the nature, cause, and extent of the delamination 
of the internal walls of a flexible hose, and eventually to develop 
final action to address the unsafe condition. Once final action has 
been identified, we may consider further rulemaking.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD; therefore, providing notice and opportunity for public comment 
before the AD is issued is impracticable, and good cause exists to make 
this AD effective in less than 30 days.

[[Page 53542]]

Explanation of Change to Applicability

    We have revised the applicability of the AD to identify the model 
designation as published in the most recent type certificate data sheet 
for the affected model.

Clarification of Inspection Terminology

    In this AD, the ``visual check'' specified in Dassault Alert 
Service Bulletin F10-A312, Revision 1, is referred to as a ``detailed 
inspection.'' We have included the definition for a detailed inspection 
in a note in this AD.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any relevant written 
data, views, or arguments regarding this AD. Send your comments to an 
address listed in the ADDRESSES section. Include ``Docket No. FAA-2005-
22309; Directorate Identifier 2005-NM-159-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD that might 
suggest a need to modify it.
    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 with FAA 
personnel concerning this AD. Using the search function of that Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.). 
You can review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78), or you can visit

Examining the Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Management Facility office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT 
street address stated in the ADDRESSES section. Comments will be 
available in the AD docket shortly after the Docket Management System 
receives them.

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 AD will not have federalism 
implications under Executive Order 13132. This AD will 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 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

actions have already been done.

Restatement of the Requirements of AD 2005-07-23

Repetitive Inspections, or Airplane Flight Manual (AFM) Revision 
and Placard Installation

    (f) Within 14 days after April 26, 2005 (the effective date of 
AD 2005-07-23), perform the actions specified in either paragraph 
(f)(1) or (f)(2) of this AD:
    (1) Revise the Limitations section of the Dassault Aviation 
Falcon 10 AFM, and install a placard in the flight deck, to include 
the following information.

``Flights into known or forecasted icing conditions are 
prohibited.''

    The AFM revision may be done by inserting a copy of this AD into 
the AFM. Install the placard on the pedestal in clear view of the 
pilot.
    (2) Determine the part number of each flexible hose installed in 
the slat anti-icing system, perform a detailed inspection of the 
internal walls of the hoses for delamination, and perform any 
applicable corrective action, by accomplishing all of the applicable 
actions specified in the Accomplishment Instructions of Dassault 
Alert Service Bulletin F10-A312, dated February 25, 2005. If the 
part number for any hose cannot be determined, before further 
flight, replace that hose with a hose having part number (P/N) 
FAL1005D. Any corrective action must be

[[Page 53543]]

done before further flight. Repeat the detailed inspection 
thereafter at intervals not to exceed 60 flight cycles or 3 months, 
whichever is first, until the actions required by paragraph (i) of 
this AD are accomplished.

    Note 1: When a statement identical to that in paragraph (f)(1) 
of this AD has been included in the general revision of the AFM, the 
general revision may be inserted into the AFM, and the copy of this 
AD may be removed from the AFM.


    Note 2: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

    (g) For airplanes on which the actions described in paragraph 
(f)(1) of this AD are performed, doing the actions described in 
paragraph (f)(2) of this AD is terminating action for the 
requirements of paragraph (f)(1) of this AD. Once the initial 
detailed inspection specified in paragraph (f)(2) of this AD is 
performed, the AFM limitation and placard required by paragraph 
(f)(1) of this AD may be removed.

New Requirements of This AD

New Inspections and Intervals

    (h) For airplanes not operated under the limitation in paragraph 
(f)(1) of this AD, before the next 10 flight cycles in which the 
slat anti-icing system is activated after the effective date of this 
AD: Do a boroscope inspection of each flexible hose installed in the 
slat anti-icing system. Do all the inspections and any applicable 
corrective action (including replacing the hose with a new hose 
having P/N FAL1005D), by accomplishing all of the applicable actions 
specified in the Accomplishment Instructions of Dassault Alert 
Service Bulletin F10-A312, Revision 1, dated June 27, 2005. Any 
corrective action must be done before further flight. Repeat the 
inspection thereafter at intervals not to exceed 10 flight cycles in 
which the slat anti-icing system is activated. Doing this inspection 
terminates the repetitive inspection requirements of paragraph 
(f)(2) of this AD.
    (i) For airplanes on which the actions described in paragraph 
(f)(1) of this AD are performed, doing the actions described in 
paragraph (h) of this AD is terminating action for the requirements 
of paragraph (f)(1) of this AD. Once the initial boroscope 
inspection specified in paragraph (h) of this AD is performed, the 
AFM limitation and placard required by paragraph (f)(1) of this AD 
may be removed.

AFM Revision

    (j) For airplanes not operated under the limitation in paragraph 
(f)(1) of this AD, before further flight after the effective date of 
this AD: Revise the Limitations section of the Dassault Aviation 
Falcon 10 AFM, to include the following information.

    ``After each flight in which the slat anti-ice system is 
activated, inform maintenance.''

    The AFM revision may be done by inserting a copy of this AD into 
the AFM.

    Note 3: When a statement identical to that in paragraph (j)(1) 
of this AD has been included in the general revision of the AFM, the 
general revision may be inserted into the AFM, and the copy of this 
AD may be removed from the AFM.

Optional Replacement

    (k) For airplanes not operated under the limitation in paragraph 
(f)(1) of this AD: Replacing the flexible hose installed in the slat 
anti-icing system with a new hose having P/N FAL1007, in accordance 
with the Accomplishment Instructions of Dassault Service Bulletin 
F10-313, dated August 10, 2005, terminates the repetitive inspection 
intervals of paragraph (h) and (f)(2) of this AD. Repeat the 
replacement thereafter at intervals not to exceed 90 flight cycles 
in which the slat anti-icing system is activated.

Reporting Requirement

    (l) At the applicable time specified in paragraph (l)(1) or 
(l)(2) of this AD: After performing any inspection required by this 
AD, submit a report of the findings (positive and negative) of the 
inspection to: Dassault Falcon Jet, Attn: Service Engineering/Falcon
