Airworthiness Directives; Rockwell Collins, Inc. Flight Display 
System Application

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD is effective July 23, 2019.
    The FAA must receive comments on this AD by August 22, 2019.

SUPPLEMENTARY INFORMATION:

Discussion

    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.

FAA's Determination

    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.

AD Requirements

    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.

Interim Action

    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

[[Page 32261]]

operating 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.

Comments Invited

    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:

----------------------------------------------------------------------------------------------------------------

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.

Regulatory Findings

    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.
