[Federal Register Volume 82, Number 160 (Monday, August 21, 2017)] [Rules and Regulations] [Pages 39525-39529] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-16579] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0130; Product Identifier 2016-NM-058-AD; Amendment 39-18986; AD 2017-16-09] RIN 2120-AA64 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.

[[Page 39526]] 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 ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection......................... 1 work-hour x $85 per hour $0 $85 $25,670 = $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: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Installation of brake hose................. 1 work-hour x $85 per hour = $85... $340 $425 Installation of protective wraps........... 1 work-hour x $85 per hour = $85... 340 425 Replacement................................ 1 work-hour x $85 per hour = $85... 340 425 ---------------------------------------------------------------------------------------------------------------- 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
