Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Dassault Aviation Model MYSTERE-FALCON 50 airplanes and FALCON 2000 
airplanes. This AD was prompted by a report indicating that during 
ground maintenance, a Model FALCON 2000 airplane experienced a loss of 
hydraulic pressure affecting both hydraulic systems due to damage to 
both brake hoses on the main landing gear (MLG). This AD requires an 
inspection for certain brake hoses, installation of protective wraps or 
installation of certain brake hoses, and replacement of certain brake 
hoses. We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective September 25, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 25, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Dassault Aviation Model 
MYSTERE-FALCON 50 airplanes and FALCON 2000 airplanes. The NPRM 
published in the Federal Register on March 23, 2017 (82 FR 14832) 
(``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2013-0255, dated October 23, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Dassault Aviation Model MYSTERE-
FALCON 50 airplanes and FALCON 2000 airplanes. The MCAI states:

    During ground maintenance, a Falcon 2000 aeroplane experienced a 
loss of hydraulic pressure, affecting both hydraulic systems.
    The investigation results revealed that this event was due to 
damage to both brake hoses on the same main landing gear (MLG), 
which chafed against the torque link assembly during MLG extension/
retraction cycle. The Part Numbers (P/N) of the affected brake hoses 
are P/N AE705317-1 and P/N 00-200-1268, which are made of a braided 
stainless steel sleeve.
    This condition, if not detected and corrected, could lead to 
loss of braking during landing or a rejected take-off, possibly 
resulting in a runway excursion. In addition, there is a risk of 
fire if the leaking brake hydraulic fluid reaches hot parts.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the brake hoses to identify the P/N and determine 
the presence of protection against chafing and, depending on 
findings, installation of protective wraps or replacement of the 
brake hoses with serviceable parts that have a Dacron sleeve 
protection.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0130.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Clarify the Applicability

    Dassault Aviation requested that the ``Applicability'' paragraph of 
the proposed AD be clarified. Dassault Aviation stated the 
``Applicability'' paragraph should be clarified to state that the 
proposed AD affects Dassault Aviation Model MYSTERE-FALCON 50 airplanes 
(including all commercial variants) and FALCON 2000 airplanes. Dassault 
Aviation stated that all commercial variants include F50EX airplanes.
    We agree to clarify the applicability of this AD. Paragraph (c) of 
this AD specifies all Dassault Aviation Model MYSTERE-FALCON 50 
airplanes and FALCON 2000 airplanes. The applicability of this AD 
identifies model designations as published in the most recent type 
certificate data sheet for the affected models. We have revised this AD 
by adding a new Note 1 to paragraph (c) of this AD to state that Model 
MYSTERE-FALCON 50 airplanes include all commercial variants, including 
F50EX airplanes.

Request To Revise the Compliance Time Threshold

    NetJets requested that we revise the compliance time threshold in 
paragraph (h) of the proposed AD. NetJets commented that paragraph (h) 
of the proposed AD requires that the protective wrap installation be 
performed concurrently with paragraph (g) of the proposed AD. NetJets 
stated that if the compliance time threshold in paragraph (h) of the 
proposed AD was changed to ``within 9 months after the effective date 
of this AD,'' it would allow a records review per paragraph (g) and 
compliance with paragraph (h) without unnecessarily grounding airplanes 
and also maintain the intended compliance threshold of the NPRM. 
NetJets stated that paragraph (g) of the proposed AD may be performed 
by a records inspection, which could be accomplished independently of 
access to the airplane and could possibly ground an airplane due to 
records discrepancies well before the compliance time threshold 
specified in paragraph (g) of the proposed AD.
    We agree with the commenter's request. We have revised paragraph 
(h) of this AD to include a compliance time of 9 months, which 
corresponds with the compliance time in the MCAI.

Request To Use Messier-Dowty Service Information

    NetJets requested that the NPRM be revised to include Messier-Dowty 
service information as an optional method of compliance. NetJets stated 
that paragraph (i) of the proposed AD specifies compliance using 
Dassault Service Bulletin F50-518, dated April 14, 2011, and Dassault 
Service Bulletin F2000-368, dated May 29, 2009, which incorporate 
Messier-Dowty Service Bulletin C23791-32-062, dated February 22, 2011, 
and Messier-Dowty Service Bulletin D23345-32-020, dated May 14, 2009, 
respectively. Net Jets stated that new and overhauled landing gear 
include compliance information with the Messier-Dowty service 
information, but not with the Dassault service information; therefore, 
compliance with the Messier-Dowty service information should be 
included as optional methods of compliance with paragraph (i) of the 
proposed AD in addition to the Dassault service information.
    We agree with the commenter's request. We agree that in the 
Accomplishment Instructions of Dassault Service Bulletin F50-518, dated 
April 14, 2011; and Dassault Service Bulletin F2000-368, dated May 29, 
2009, specifies to replace the MLG brake hose using Messier-Dowty 
Service Bulletin C23791-32-062, dated February 22, 2011, and Messier-
Dowty Service Bulletin D23345-32-020, dated May 14, 2009, as 
applicable. For clarification, we have added Note 2 to paragraphs 
(h)(2) and (i) of this AD to state that Dassault Service Bulletin F50-
518, dated April 14, 2011, refers to Messier-Dowty Service Bulletin 
C23791-32-062, dated February 22, 2011; and Dassault Service Bulletin 
F2000-368, dated May 29, 2009, refers to Messier-Dowty Service Bulletin 
D23345-32-020, dated May 14, 2009; as additional sources of guidance 
for doing the replacement of certain brake hoses.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We have reviewed the following Dassault service information.
     Dassault Service Bulletin F50-510, Revision 2, dated 
December 20, 2012; and Dassault Service Bulletin F2000-382, Revision 2, 
dated May 12, 2011. This service information describes procedures for 
an inspection of the brake hoses to identify whether brake hoses having 
certain part numbers are

[[Page 39527]]

installed, and installation of protective wraps on the brake hoses or 
installation of certain brake hoses that are fitted with Dacron 
sleeves. These documents are distinct since they apply to different 
airplane models.
     Dassault Service Bulletin F50-518, dated April 14, 2011; 
and Dassault Service Bulletin F2000-368, dated May 29, 2009. This 
service information describes replacement of certain brake hoses. These 
documents are distinct since they apply to different airplane models.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 302 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs

                                      = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary installations 
and replacements that would be required based on the results of the 
inspection. We have no way of determining the number of aircraft that 
might need these installations and replacements:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    We 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 this AD:
    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.
