SUMMARY: 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 partnumbered 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: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Revise the Limitations section of the AFM or AFMS. .5 work-hour × $85 per hour = $42.50.

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.

    This airworthiness directive (AD) is effective April 29, 2021.

(b) Affected ADs

    This AD replaces AD 2019-12-09, Amendment 39-19664 (84 FR 32260, 
July 8, 2019) (AD 2019-12-09).

(c) Applicability

    This AD applies to Rockwell Collins, Inc., (Rockwell Collins) 
Flight Display System Application FDSA-6500 part numbers (P/Ns) 810-
0234-1H0001, 810-0234-1H0002, 810-0234-1H0003, 810-0234-2H0001, 810-
0234-2C0001, 810-0234-2C0002, and 810-0234-4B0001. These

airplanes, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 3400, NAVIGATION 
SYSTEM.

(e) Unsafe Condition

    This AD was prompted by a conflict between the traffic collision 
avoidance system (TCAS) primary display indications and aural alerts 
during a resolution advisory (RA) scenario. The FAA is issuing this 
AD to prevent conflicting TCAS information, which could result in 
the pilot under-correcting or over-correcting and may lead to 
inadequate aircraft separation and a mid-air collision.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Actions

    (1) Within 30 days after July 23, 2019 (the effective date of AD 
2019-12-09), do the following:
    (i) Revise the airplane flight manual (AFM) or AFM supplement 
(AFMS) by adding the following text to the Limitations section: For 
TCAS II installations, during flight, do not operate TCAS in the 
``TA/RA'' mode; TCAS may only be operated in ``TA Only'' mode.
    (ii) Fabricate a placard for each aircraft primary flight 
display, using at least \1/8\ inch letters, with the following text: 
TCAS Flight Ops--TA Only mode (TA/RA mode prohibited).
    (iii) Install the placard on the bottom of each aircraft primary 
flight display bezel in the area depicted in figure 1 to paragraph 
(g)(1)(iii) of this AD.

    Note 1 to paragraph (g)(1): In ``TA/RA'' mode, the TA stands for 
traffic advisory and RA stands for resolution advisory.
