Federal Aviation Administration (FAA), DOT.
Final rule; request for comments.
The FAA is adopting a new airworthiness directive (AD) for certain part-numbered Rockwell Collins, Inc. (Rockwell Collins) FDSA-6500 flight display system applications installed on airplanes. This AD imposes operating limitations on the traffic collision avoidance system (TCAS) by revising the Limitations section of the airplane flight manual (AFM) or AFM supplement (AFMS) and installing a placard on each aircraft primary flight display. This AD was prompted by a conflict between the TCAS display indications and aural alerts that may occur during a resolution advisory (RA) scenario. The FAA is issuing this AD to require actions that address the unsafe condition on these products.
This AD is effective July 23, 2019.
The FAA must receive comments on this AD by August 22, 2019.

Start Supplemental Information
The FAA was notified that a conflict may occur between the TCAS primary cockpit display indications and the aural alerts during an RA scenario on specific part-numbered Rockwell Collins FDSA-6500 flight display system applications. These applications may be installed on, but not limited to, Bombardier Inc. Model CL-600-2B16 (604 variant) airplanes and Textron Aviation Inc. Models 525B, B200, B200C, B200CGT, B200GT, B300, B300C, and C90GTi airplanes.
During testing of a full flight simulator on a development program, the TCAS fly-to/avoidance cue indication on the primary cockpit displays conflicted with other TCAS system information, such as aural cues, during an RA scenario. While the aural alert will provide the pilot with accurate information to resolve the RA, that information is not accurately represented by the TCAS fly-to/avoidance cue display. Specifically, the TCAS fly-to/avoidance cue is displayed relative to the aircraft horizon line instead of the aircraft symbol. Rockwell Collins determined that the data from the TCAS is being translated incorrectly by the FDSA-6500 software prior to display of the RA pitch indications.
This condition, if not addressed, could lead to the pilot over-correcting or under-correcting for aircraft separation and may result in a mid-air collision. The manufacturer is developing a software update to correct this condition. The actions required by this AD are intended to prevent conflicting TCAS information by prohibiting flight operation with RA functionality enabled. The FAA is issuing this AD to address the unsafe condition on these products.
Related Service Information
The FAA reviewed Rockwell Collins Operator Bulletin OPSB 0193-19R1, Revision 1, dated April 3, 2019. The service information describes the unsafe condition and provides examples of different scenarios that could occur with the TCAS indication conflicts. The service information also contains instructions for determining the part number of the FDSA-6500 installation.
The FAA is issuing this AD because it evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
This AD prohibits operation with the TCAS in TA/RA mode by requiring a revision to the Limitations section of the AFM or AFMS and by fabricating and installing a placard on each aircraft primary flight display. An owner/operator (pilot) may revise the AFM or the AFMS and fabricate and install the required placard, and the owner/operator must enter compliance with the applicable paragraphs of the AD into the aircraft records in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). A pilot may perform these actions because they can be performed equally well by a pilot or a mechanic. This is an exception to our standard maintenance regulations.
The FAA considers this AD interim action. The operating limitation required by this AD will immediately address the unsafe condition. However, Rockwell Collins is developing a software upgrade to correct the unsafe condition and eliminate the need for the Start Printed Page 32261operating limitation required by this AD action. Because the operating limitation required by this AD addresses the unsafe condition, any rulemaking with a software upgrade would allow for public notice and comment. Thus, the FAA will consider future rulemaking when the software upgrade becomes available.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because a conflict between the displayed indications and the TCAS aural alert could lead to the pilot over-correcting or under-correcting for aircraft separation and result in a mid-air collision. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days.
This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, the FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the Docket Number FAA-2019-0469 and Product Identifier 2019-CE-028-AD at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments.
The FAA will post all comments it receives, without change, to http://www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact it receives about this final rule.
Costs of Compliance
The FAA estimates that this AD affects 932 FDSA-6500 flight display system applications installed on 311 airplanes worldwide. The number of FDSA-6500 applications installed on airplanes on the U.S. Registry is unknown.
The FAA estimates the following costs to comply with this AD:
|Action||Labor cost||Parts cost||Cost per product||Cost on operators
|Revise the Limitations section of the AFM or AFMS||.5 work-hour × $85 per hour = $42.50||Not applicable||$42.50 (per airplane)||$13,217.50|
|Fabricate and install a placard||.5 work-hour × $85 per hour = $42.50||Negligible||$42.50 (per primary flight display)||39,610|
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.
The FAA is 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.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required.
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, and
(2) Will not affect intrastate aviation in Alaska.
