Airworthiness Directives; Rockwell Collins, Inc. Flight Display System Application Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is superseding Airworthiness Directive AD AD 2019
1209 for certain Rockwell Collins, Inc.
Rockwell Collins FDSA6500 flight display system applications installed on airplanes. AD 20191209 imposed operating limitations on the traffic collision avoidance system TCAS. AD
20191209 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
20191209 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.

SUMMARY:

Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20191209, Amendment 3919664 84 FR 32260, July 8, 2019, AD 20191209. AD
20191209 applied to certain partnumbered Rockwell Collins FDSA6500
flight display system applications that may be installed on, but not limited to, Bombardier Inc. Model CL6002B16
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 20191209 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 20191209 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
20191209 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 20191209
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 FDSA6500
191, Revision No. 2, dated June 12, 2019. This service information letter contains information regarding hardware and software compatibility for the FDSA6500 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 FDSA6500 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:
