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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) AD 2019-
12-09 for certain Rockwell Collins, Inc. (Rockwell Collins) FDSA-6500 
flight display system applications installed on airplanes. AD 2019-12-
09 imposed operating limitations on the traffic collision avoidance 
system (TCAS). AD 2019-12-09 was prompted by conflict between the TCAS 
display indications and aural alerts that may occur during a resolution 
advisory (RA) scenario. This AD retains the requirements of AD 2019-12-
09 until a software upgrade is completed. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective April 29, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 29, 
2021.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-12-09, Amendment 39-19664 (84 FR 
32260, July 8, 2019), (AD 2019-12-09). AD 2019-12-09 applied to certain 
part-numbered Rockwell Collins FDSA-6500 flight display system 
applications that 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. The NPRM published in the Federal Register on December 14, 
2020 (85 FR 80686).
    AD 2019-12-09 prohibited operation with the TCAS in TA/RA mode by 
requiring a revision to the Limitations section of the airplane flight 
manual (AFM) or AFM supplement (AFMS) and by fabricating and installing 
a placard on each aircraft primary flight display. AD 2019-12-09 
resulted from a report that a conflict could occur between the TCAS 
primary cockpit display indications and the aural alerts during an RA 
scenario. The FAA issued AD 2019-12-09 as an interim action to address 
the immediate urgency to prevent the pilot from over-correcting or 
under-correcting for aircraft separation, which may result in a mid-air 
collision.
    In the NPRM, the FAA proposed to retain the actions of AD 2019-12-
09 and install updated software on the flight data system applications 
within 12 months. Once the software is upgraded, the FAA proposed to 
allow removal of the limitations and placard. Because the requirements 
proposed in the NPRM had a longer compliance time, the FAA provided the 
public an opportunity to comment. The FAA is issuing this AD to address 
the unsafe condition on these products.

Discussion of Final Airworthiness Directive Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adoption of the AD as proposed. Accordingly, the FAA is 
issuing this AD to address the unsafe condition on these products. This 
AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Rockwell Collins Service Information Letter FDSA-
6500-19-1, Revision No. 2, dated June 12, 2019. This service 
information letter contains information regarding hardware and software 
compatibility for the FDSA-6500 flight display system and provides 
software download instructions. 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 
ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 932 FDSA-6500 flight display 
system applications installed on 311 airplanes worldwide. The FAA has 
no way of knowing the number of FDSA-6500 applications installed on 
airplanes of U.S. Registry. The estimated cost on U.S. operators 
reflects the maximum possible cost based on worldwide applications.
    The FAA estimates the following costs to comply with this AD:

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

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected operators.

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 Findings

    The FAA has 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) Will not affect intrastate aviation in Alaska, and
    (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.
