AGENCY: PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 ACTION: 39525 Final rule. 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.

E:\FR\FM\21AUR1.SGM 21AUR1 39526 Federal Register / Vol. 82, No. 160 / Monday, August 21, 2017 / Rules and Regulations 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. sradovich on DSK3GMQ082PROD with RULES 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 VerDate Sep<11>2014 16:12 Aug 18, 2017 Jkt 241001 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 PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 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 E:\FR\FM\21AUR1.SGM 21AUR1 39527 Federal Register / Vol. 82, No. 160 / Monday, August 21, 2017 / Rules and Regulations 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 Action Labor cost Inspection ................................ 1 work-hour × $85 per hour = $85 ......................................... We estimate the following costs to do any necessary installations and replacements that would be required Cost per product Parts cost based on the results of the inspection. We have no way of determining the $0 Cost on U.S. operators $85 $25,670 number of aircraft that might need these installations and replacements: ON-CONDITION COSTS Action Labor cost Installation of brake hose .............................................

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. 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.

AD 2014–20–09 applied to certain Bombardier, Inc., Model DHC–8–400 series airplanes. The NPRM published in the Federal Register on February 22, 2017 (82 FR 11325). The NPRM was prompted by reports of missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension. The NPRM proposed to continue to require an PO 00000 Frm 00039 Fmt 4700 Sfmt 4700 39529 inspection for missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension, could result in an in-flight fire. Since we issued AD 2014–20–09, the FAA has determined that certain airplane serial numbers that are in a premodification MS 4M153025 configuration have sufficient space between the AC feeder cables and the landing gear alternate extension hydraulic line, and do not pose an inflight fire risk. Therefore, these airplanes are not subject to the identified unsafe condition. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–16R1, effective July 26, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model DHC–8–400 series airplanes. The MCAI states: During production checks, it was found that the appropriate clamps required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension were omitted. The AC feeder cable could sag and be in direct contact with the swage fitting of the landing gear alternate extension hydraulic line, resulting in chafing of the AC feeder cable. The chafed and arcing AC feeder cable could puncture the adjacent hydraulic line. In combination with the use of the alternate extension system, this could result in an in-flight fire. The original issue of this [Canadian] AD was issued to mandate the incorporation of [Bombardier] service bulletin (SB) 84–24–53 to * * * [do a general visual inspection for the presence of correctly installed clamps] and rectify, as necessary, for proper clamp installation. Bombardier, Inc. has revised [Bombardier] SB 84–24–53 to remove serial numbers 4001 through 4034 from the Effectivity section, as it was determined that these serial numbers are Pre-Mod MS 4M153025, which allowed sufficient space between the AC feeder cables and the landing gear alternate extension hydraulic line to not pose an in-flight fire risk. Accordingly, revision 1 of this [Canadian] AD is issued to revise the Applicability section to reflect the Effectivity changes in [Bombardier] SB 84–24–53 Revision B, dated 10 September 2015.

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.

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:

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

    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.

Instructions of Dassault Service Bulletin F50-518, dated April 14, 
2011; or Dassault Service Bulletin F2000-368, dated May 29, 2009; as 
applicable.
    Note 2 to paragraphs (h)(2) and (i) of this AD: 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.

(i) Replacement

    Within 6,000 flight cycles, or within 149 months, whichever 
occurs first after the effective date of this AD: Replace brake 
hoses having P/N AE705317-1 and P/N 00-200-1268 with brake hoses 
having P/N 00-200-1534 that are fitted with Dacron sleeves, in 
accordance with the Accomplishment Instructions of Dassault Service 
Bulletin F50-518, dated April 14, 2011; or Dassault Service Bulletin 
F2000-368, dated May 29, 2009; as applicable. Once brake hoses 
having P/N 00-200-1534 are fitted in an MLG leg, no further action 
is required for that MLG leg, as specified in paragraph (j) of this 
AD.

(j) Provisions for Unaffected MLG Leg Assemblies

    If, during the inspection required by paragraph (g) of this AD, 
it is determined that the airplane is equipped with an MLG leg 
assembly with a part number specified in table 1 to paragraph (j) of 
this AD, the requirement of paragraph (h) of this AD is not 
applicable, provided that the MLG leg assembly has not been modified 
in service after its installation on an airplane.
