AD 2020-19-13

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by a report that fast and easy access to the portable oxygen bottle may be prevented by the portable oxygen bottle installation's upper bracket latch assembly catching on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. This AD requires a check to identify the manufacturer and part number of the portable oxygen bottle installation, and, if necessary, modification of the portable oxygen bottle installation. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

Discussion \n\n\n\tTransport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2019-26, dated July 9, 2019 (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020- 0203. \n\tThe FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601- 3A, 601-3R, and 604 Variants) airplanes. The NPRM published in the Federal Register on March 23, 2020 (85 FR 16284). The NPRM was prompted by a report that fast and easy access to the portable oxygenbottle may be prevented by the portable oxygen bottle installation's upper bracket latch assembly catching on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. The NPRM proposed to require a check to identify the manufacturer and part number of the portable oxygen bottle installation, and, if necessary, modification of the portable oxygen bottle installation. The FAA is issuing this AD to address the portable oxygen bottle installation's upper bracket latch assembly catching on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle, which, if not detected and corrected, could prevent fast and easy access to the portable oxygen bottle in an emergency situation. See the MCAI for additional background information. \n\nComments \n\n\n\tThe FAA 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 to each comment. \n\nSupportfor the NPRM \n\n\n\tAn anonymous commenter had no objection to the NPRM. \n\nRequest To Revise or Clarify the Applicability of Paragraph (i) of the Proposed AD \n\n\n\tNetJets requested that the FAA either revise the language in the first sentence of paragraph (i) of the proposed AD to clearly state that the paragraph applies to airplanes having a serial number of 6119 and below that is not listed in section 1.A. of the applicable Bombardier service information specified in figure 1 to paragraphs (g), (h), and (i) of the proposed AD, or that the FAA clarify paragraph (c)(3) of the proposed AD to state that all serial numbers are affected. \n\tThe FAA agrees to clarify. Paragraph (i) of the proposed AD is applicable to only airplanes having the serial numbers specified in paragraph (c) of this AD, but not listed in section 1.A. of the applicable Bombardier service information specified in figure 1 to paragraphs (g), (h), and (i) of this AD, and equipped with specified part numbers of Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot portable oxygen bottle(s). As such, any serial number not specified in paragraph (c)(3) of this AD for Bombardier Inc. Model CL-600-2B16 (601- 3A, 601-3R, and 604 Variants) airplanes, is not affected by paragraph (i) of this AD. The FAA has not changed this AD in this regard. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: \n\tAre consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tBombardier has issued the following service information: \n\tBombardier Service Bulletin 600-0772, dated June 29, 2018; \n\tBombardier Service Bulletin 601-0646, dated June 29, 2018; \n\tBombardier Service Bulletin 604-35-006, dated June 29, 2018; \n\tBombardier Service Bulletin 605-35-005, dated June 29, 2018; and \n\tBombardier Service Bulletin 650-35-001, dated June 29, 2018. \n\tThis service information describes procedures for a check to identify the manufacturer and part number of the portable oxygen bottle installation, and, if necessary, modification of the portable oxygen bottle installation. 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. \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 188 airplanes of U.S. registry. We estimate the following costs to comply with this AD: \n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tLabor cost Parts cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- 3 work-hours x $85 per hour = $255 $1,530 per installation $1,785 per installation $335,580 per \n\tper installation. installation. ---------------------------------------------------------------------------------------------------------------- \n\n\n\n((Page 60889)) \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tThe FAA is issuing this rulemaking under the authority described in Subtitle VII, PartA, 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. \n\nRegulatory Findings \n\n\n\tThis 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Will not affect intrastate aviation in Alaska, and \n\t(3) 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. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
