ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 2016-25-18, which applied to certain Bombardier, Inc., Model BD-700-1A10 and BD- 700-1A11 airplanes. AD 2016-25-18 required an inspection for discrepancies of the attachment points of the links between the engine rear mount assemblies, and corrective actions if necessary. This AD requires an inspection of certain attachment points, corrective action if necessary, and replacement of certain bolts and nuts in the engine rear mount assemblies. This AD also adds airplanes to the applicability. This AD was prompted by the determination that replacement of certain nuts and bolts in the engine rear mount assemblies is necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective June 15, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 15, 2018.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2016-25-18, Amendment 39-18744 (81 FR 90961, [[Page 21856]] December 16, 2016) (``AD 2016-25-18''). AD 2016-25-18 applied to certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the Federal Register on August 15, 2017 (82 FR 38626). The NPRM was prompted by the determination that replacement of certain nuts and bolts in the engine rear mount assemblies is necessary. The NPRM proposed to continue to require an inspection for discrepancies of the attachment points of the links between the engine rear mount assemblies, and corrective actions if necessary. The NPRM also proposed to require an inspection of certain attachment points, corrective action if necessary, and replacement of certain bolts and nuts in the engine rear mount assemblies. The NPRM also proposed to add airplanes to the applicability. We are issuing this AD to detect and correct broken engine attachment hardware, which could result in separation of an engine from the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2016-23R1, dated February 20, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700- 1A11 airplanes. The MCAI states: Bombardier reported that during maintenance of a BD-700 aeroplane, the engine mount pin, part number (P/N) BRR15838, was found backed out of the rear mount link. The retaining bolt, P/N AS54020, which passes through the engine mount pin was also found fractured at the groove which holds the locking spring. An investigation revealed the most probable root cause of failure to be a single axial tension static overload, with no evidence of fatigue contributing to the failure. The above condition if not detected, may result in the loss of engine attachment to the airframe. As an interim corrective action, Bombardier issued Service Bulletins (SBs) 700-71-002, 700-71-6002, 700-71-5002, and 700-1A11- 71-002 to inspect the attachment points of the links between the engine rear mount assemblies, and install replacement hardware if required. The original version of this [Canadian] AD was issued to mandate incorporation of the above Bombardier SBs to inspect and maintain integrity of the affected engine rear mount assembly. Revision 1 of this [Canadian] AD is issued to mandate incorporation of the Bombardier SBs 700-71-003, 700-71-6003, 700-71- 5003, and 700-1A11-71-003 to replace the existing bolts and self- locking nuts with new bolts and nuts, as a final corrective action. The MCAI also adds airplanes having serial numbers 9764, 9766, and 9771 through 9785 inclusive to the applicability. Those airplanes are also affected by the identified unsafe condition. 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-2017-0775. 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. Requests To Provide Credit for Actions Previously Accomplished NetJets Aviation requested that we provide credit for accomplishing the actions specified in paragraphs (j) and (k) of the proposed AD prior to the effective date of this AD. Bombardier requested that we provide credit for accomplishing the actions specified in paragraphs (k) and (l) of the proposed AD prior to the effective date of this AD. We acknowledge the commenters' requests and agree to clarify. Paragraph (f) of this AD states to accomplish the required actions within the compliance times specified, ``unless already done.'' Therefore, if operators have accomplished the actions required for compliance with this AD before the effective date of this AD, no further action is necessary. We have not revised this AD in this regard. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for 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.

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 97 airplanes of U.S. registry. The actions required by AD 2016-25-18, and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2016-25-18 is $85 per product. The retained on-condition costs in this AD take about 2 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $730 per product. Based on these figures, the estimated cost of the on-condition actions that are required by AD 2016-25-18 is $900 per product. We have received no definitive data that would enable us to provide cost estimates for other retained on-condition actions specified in AD 2016-25-18. We also estimate that it will take about 4 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost up to $14,940 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be up to $1,482,160, or up to $15,280 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. According to the manufacturer, some of the costs of this AD may be covered [[Page 21857]] under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate. 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.
