ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 2013-11-12, which applied to certain Bombardier, Inc., Model BD-100-1A10 airplanes. AD 2013-11-12 required inspecting for the correct serial number of a certain hydraulic system accumulator, and replacing affected hydraulic system accumulators with new or serviceable accumulators. This AD expands the applicability and requires modifying or replacing certain hydraulic brake system accumulators. This AD also requires revising the maintenance or inspection program to add life limits for the accumulators. This AD was prompted by a determination that certain other hydraulic system accumulators must be modified or replaced and life limits must be added. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective November 23, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 23, 2018. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of July 9, 2013 (78 FR 33206, June 4, 2013).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013-11-12, Amendment 39-17472 (78 FR 33206, June 4, 2013) (``AD 2013-11-12''). AD 2013-11-12 applied to certain Bombardier, Inc., Model BD-100-1A10 airplanes. The NPRM published in the Federal Register on March 9, 2018 (83 FR 10415). The NPRM was prompted by a determination that certain other hydraulic system accumulators must be modified or replaced and life limits must be added. The NPRM proposed to continue to require inspecting for the correct serial number of a certain hydraulic system accumulator, and replacing affected hydraulic system accumulators with new or serviceable accumulators. The NPRM also proposed to expand the applicability and require modifying or replacing certain hydraulic brake system accumulators. The NPRM also proposed to require revising the maintenance or inspection program to add life limits for the accumulators. We are issuing this AD to prevent failure of a screw cap or end cap and loss of the related hydraulic system, which could result in damage to airplane structure and consequent reduced controllability of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2011-41R1, dated March 27, 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-100- 1A10 airplanes. The MCAI states: Seven cases of on-ground hydraulic accumulator screw cap/end cap failure have been experienced on CL-600-2B19 aeroplanes, resulting in loss of the associated hydraulic system and high-energy impact damage to adjacent systems and structure. To date, the lowest number of flight cycles accumulated at the time of failure has been 6991. Although there have been no failures to date on any BD-100-1A10 aeroplanes, accumulators similar to those installed on the CL-600- 2B19 are installed on the BD-100-1A10. The affected part numbers (P/ Ns) of the accumulators installed on BD-100-1A10 are 900095-1 (Auxiliary Hydraulic System accumulator), 33-155500 (Inboard Brake accumulator), and 33-147500 (Outboard Brake accumulator). A detailed analysis of the calculated line of trajectory of a failed screw cap/end cap for the accumulators has been conducted, resulting in the identification of areas where systems and/or structural components could potentially be damaged. Although all of the failures on the CL-600-2B19 to date have occurred on the ground, an in-flight failure affecting such components could potentially have an adverse effect on the controllability of the aeroplane. Revision 1 of this [Canadian] AD is issued to mandate the [inspection and] replacement [of] Brake System Hydraulic accumulators that are not identified by the letter ``E'' or ``NAE'' after the serial number on the identification plate. Revision 1 also mandates the re-orientation of the brake accumulators P/N 33-147500 and P/N 33-155500 and the insertion of three discard tasks in the Challenger 300 Time Limits/Maintenance Checks (TLMC) Manual. 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-2018- 0161. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA's response. Request To Add Maintenance Manual NetJets Aviation stated that paragraph (n) of the proposed AD, which requires revising the maintenance or inspection program to incorporate certain life limit tasks, does not reference the Bombardier Challenger 350 Time Limits/Maintenance Check (TLMC) Manual. NetJets Aviation noted that only the Bombardier Challenger 300 TLMC Manual is referenced. We infer that the commenter is asking that the Bombardier Challenger 350 TLMC Manual be added as another source of service information for accomplishing the actions required by paragraph (n) of this AD. We agree with the commenter's request and have changed paragraph (n) accordingly. Although the tasks identified in the Bombardier Challenger 300 TLMC Manual also apply to Bombardier Challenger 350 airplanes, we have included the Bombardier Challenger 350 TLMC in this AD for clarity. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule with the change 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 addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that this change will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information: Service Bulletin 100-32-20, Revision 02, dated April 14, 2015, which describes procedures for modifying (e.g., re-orienting) the installation of the hydraulic brake accumulators. Service Bulletin 100-32-21, dated May 24, 2012, which describes procedures for replacing the hydraulic brake system accumulators. Task 29-21-13-101 Discard the Auxiliary Hydraulic System Accumulator, Part No. 900095-1, of Section 5-10-11 of Part 2, ``Airworthiness Limitations,'' of Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Manual, Revision 17, dated December 15, 2016; and Bombardier Challenger 350, BD-100 Time Limits/Maintenance Checks Manual, Revision 9, dated December 18, 2017, which describes procedures for removal and installation of the hydraulic brake system accumulators. These tasks are distinct since they apply to different airplane models. Task 32-43-37-101 Discard the Brake Accumulator, Part No. 33-147500, of Section 5-10-11 of Part 2, ``Airworthiness Limitations,'' of Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Manual, Revision 17, dated December 15, 2016; and Bombardier Challenger [[Page 52758]] 350, BD-100 Time Limits/Maintenance Checks Manual, Revision 9, dated December 18, 2017, which describes procedures for removal and installation of the brake accumulators. These tasks are distinct since they apply to different airplane models. Task 32-44-05-101 Discard the Emergency/Parking Brake Accumulator, Part No. 33-155500, of Section 5-10-11 of Part 2, ``Airworthiness Limitations,'' of Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Manual, Revision 17, dated December 15, 2016; and Bombardier Challenger 350, BD-100 Time Limits/Maintenance Checks Manual, Revision 9, dated December 18, 2017, which describes procedures for removal and installation of the emergency parking brake accumulators. These tasks 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 187 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs -------------------------------------------------------------------------------------------------------------------------------------------------------- Action Labor cost Parts cost Cost per product Cost on U.S. operators -------------------------------------------------------------------------------------------------------------------------------------------------------- Inspection to determine part 1 work-hour x $85 per $0............................ $85........................... $15,895. numbers (retained actions from AD hour = $85. 2013[dash]11[dash]12). Modifying or replacing hydraulic 58 work-hours x $85 Up to $31,500................. Up to $36,430................. Up to $6,812,410. brake system accumulators (new per hour = $4,930. actions). -------------------------------------------------------------------------------------------------------------------------------------------------------- We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per- operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour). We estimate the following costs to do any necessary replacements that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements. On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Hydraulic accumulator replacement.......... 5 work-hours x $85 per hour = $340. $4,510 $4,850 ---------------------------------------------------------------------------------------------------------------- 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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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) 2013-11-12, Amendment 39-17472 (78 [[Page 52759]] FR 33206, June 4, 2013), and adding the following new AD: 2018-20-16 Bombardier, Inc.: Amendment 39-19450; Docket No. FAA- 2018-0161; Product Identifier 2017-NM-088-AD. (a) Effective Date This AD is effective November 23, 2018. (b) Affected ADs This AD replaces AD 2013-11-12, Amendment 39-17472 (78 FR 33206, June 4, 2013) (``AD 2013-11-12''). (c) Applicability This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, having serial numbers 20003 through 20604 inclusive. (d) Subject Air Transport Association (ATA) of America Code 29, Hydraulic Power. (e) Reason This AD was prompted by reports of failure of a screw cap or end cap of the hydraulic system accumulator while on the ground, which resulted in loss of use of that hydraulic system and high-energy impact damage to adjacent systems and structures. We are issuing this AD to prevent failure of a screw cap or end cap and loss of the related hydraulic system, which could result in damage to airplane structure and consequent reduced controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done.
