Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-19-
08, for all Dassault Aviation Model Falcon 10 airplanes. AD 2008-19-08 
currently requires repetitive replacement of the flexible hoses 
installed in the wing (slat) anti-icing system with new hoses. Since we 
issued AD 2008-19-08, additional reports were received of collapse of 
the flexible hoses installed in the slat anti-icing systems on 
airplanes equipped with new, improved hoses. This proposed AD would 
require reducing the life limit of these flexible hoses, which would 
reduce the repetitive replacement intervals. We are proposing 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: We must receive comments on this proposed AD by June 17, 2016.

Discussion

    On September 12, 2008, we issued AD 2008-19-08, Amendment 39-15675 
(73

[[Page 26496]]

FR 54492, September 22, 2008) (``AD 2008-19-08''). AD 2008-19-08 
requires actions intended to address an unsafe condition on all 
Dassault Aviation Model Falcon 10 airplanes.
    Since we issued AD 2008-19-08, additional reports were received of 
collapse of the flexible hoses installed in the slat anti-icing systems 
on airplanes equipped with new, improved hoses.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0104, dated May 7, 2014 (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition on all Dassault Aviation Model 
Falcon 10 airplanes. The MCAI states:

    Occurrences were reported involving an in-service Falcon 10 
aeroplane, where wing anti-ice hoses collapsed. The subsequent 
investigation revealed that the flexible hose, Part Number (P/N) 
FAL1005, collapsed because of an internal ply separation.
    This condition, if not corrected, could lead to failure of the 
ice-protection system to remove ice accretion on the wing, possibly 
resulting in reduced control of the aeroplane.
    To address this potential unsafe condition, EASA issued AD 2005-
0020 and AD 2006-0114 [which corresponds to AD 2008-19-08], 
respectively, imposing flight limitations and requiring replacement 
of the flexible hoses P/N FAL1005 with improved hoses P/N FAL1007.
    Since those [EASA] ADs were issued, further occurrences were 
reported concerning aeroplanes with improved hoses, which led to the 
conclusion that the life limit of the flexible hose P/N FAL1007 must 
be reduced.
    For the reasons above, this [EASA] AD retains the requirements 
of EASA AD 2006-0114, which is superseded; supersedes EASA AD 2005-
0020; requires replacement of flexible hoses having P/N FAL 1000, P/
N 1001, P/N FAL1005, or P/N FAL1005D, and reduces the life limit of 
the flexible hoses P/N 1007 [which would reduce the repetitive 
replacement intervals].

6146.

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. 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.

Costs of Compliance

    We estimate that this proposed AD affects 124 airplanes of U.S. 
registry.
    The actions that are required by AD 2008-19-08 and retained in this 
proposed AD take about 8 work-hours per product, at an average labor 
rate of $85 per work-hour. Required parts cost about $880. Based on 
these figures, the estimated cost of the actions that are required by 
AD 2008-19-08 is up to $1,560, per replacement cycle.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $936 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $158,224, or $1,276 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, 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

0
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]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2008-19-08, Amendment 39-15675 (73 FR 54492, September 22, 2008), and 
adding the following new AD:

Dassault Aviation: Docket No. FAA-2016-6146; Directorate Identifier 
2014-NM-120-AD.

(a) Comments Due Date

    We must receive comments by June 17, 2016.

(b) Affected ADs

    This AD replaces AD 2008-19-08, Amendment 39-15675 (73 FR 54492, 
September 22, 2008) (``AD 2008-19-08'').

(c) Applicability

    This AD applies to all Dassault Aviation Model Falcon 10 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 30, Ice and Rain 
Protection.

(e) Reason

    This AD was prompted by reports of collapse of the flexible 
hoses installed in the slat anti-icing systems on airplanes equipped 
with new, improved hoses. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

[[Page 26497]]

(g) Retained Repetitive Hose Replacement With Revised Compliance 
Language

    This paragraph restates the requirements of paragraph (h) of AD 
2008-19-08, with revised compliance language. As of October 27, 2008 
(the effective date of AD 2008-19-08), replace the flexible hoses 
installed in the slat anti-icing system with new hoses having part 
number (P/N) FAL1007, in accordance with the Accomplishment 
Instructions of Dassault Service Bulletin F10-313, Revision 1, dated 
May 10, 2006, within 700 flight hours since the last replacement or 
within 100 flight hours after October 27, 2008, whichever occurs 
later, and thereafter at intervals not to exceed 700 flight hours. 
Accomplishing the replacement required by paragraph (h) of this AD 
ends the repetitive inspections required by this paragraph.

(h) New Requirement of This AD: Hose Replacement for Certain Part 
Numbers

    Within 65 days after the effective date of this AD: Replace any 
flexible hose having part number (P/N) FAL1000, P/N FAL1001, or P/N 
FAL1005D with a new, improved flexible hose having P/N FAL1007, 
using a method approved by the Manager, International Branch, ANM-
116, Transport Airplane Directorate, FAA; or the European Aviation 
Safety Agency (EASA); or Dassault Aviation's EASA Design 
Organization Approval (DOA).

(i) Life-limit for P/N FAL1007--Repetitive Replacements

    At the later of the times specified in paragraphs (i)(1) and 
(i)(2) of this AD, replace any flexible hose having part number P/N 
FAL1007 with a serviceable flexible hose having P/N FAL1007, using a 
method approved by the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA; or EASA; or Dassault Aviation's 
EASA DOA. Thereafter, before the accumulation of 350 flight hours on 
any flexible hose having P/N FAL1007, replace the flexible hose with 
a serviceable flexible hose having P/N FAL1007.
    (1) Before the accumulation of 350 flight hours on the flexible 
hose P/N FAL1007 since first installation on an airplane.
    (2) At the earlier of the times specified in (i)(2)(i) and 
(i)(2)(ii) of this AD.
    (i) Within 200 flight hours after the effective date of this AD.
    (ii) Before the accumulation of 700 flight hours on the flexible 
hose P/N FAL1007 since first installation on an airplane, or within 
65 days after the effective date of this AD, whichever occurs later.

(j) Definition of Serviceable Flexible Hose

    For the purpose of this AD, a serviceable flexible hose is a 
flexible hose having P/N FAL1007 that has accumulated 350 flight 
hours or less since first installation on an airplane.

(k) Parts Installation Limitation

    After accomplishing the replacement required by paragraph (h) of 
this AD, no person may install a flexible hose in the slat anti-
icing system on any airplane, unless that hose is a serviceable 
flexible hose having P/N FAL1007, and thereafter repetitive hose 
replacements are done as required by paragraph (i) of this AD.
