Required 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. ER25MR21.001 (2) In addition to the provisions of 14 CFR 43.3 and 43.7, the actions required by paragraphs (g)(1)(i) through (iii) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417. This authority is not applicable to aircraft being operated under 14 CFR part 119. (3) Within 12 months after the effective date of this AD, upgrade the FDSA-6500 field loadable software for your airplane as listed in the table in Section C and by following the instructions in Section F of Rockwell Collins Service Information Letter FDSA-6500-19-1, Revision No. 2, dated June 12, 2019. (4) The airplane flight manual revision and placards required by paragraph (g)(1) of this AD may be removed after completing the software upgrade required by paragraph (g)(3) of this AD. (5) As of the effective date of this AD, do not install a Rockwell Collins Flight Display System Application FDSA-6500 P/N 810-0234-1H0001, 810-0234-1H0002, 810-0234-1H0003, 810-0234-2H0001, 810-0234-2C0001, 810-0234-2C0002, or 810-0234-4B0001 on any airplane.
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.
Affected ADs
This AD replaces AD 2019-12-09, Amendment 39-19664 (84 FR 32260, July 8, 2019) (AD 2019-12-09).
