Airworthiness Directive · Amendment 39-19221 · Navigation
Airbus Airplanes
This AD applies to Airbus airplanes, all manufacturer serial numbers, certificated in any category, as identified in paragraphs (c)(1) through (c)(11) of this AD; except those Model A318, A319, A320 and A321 series airplanes that have been modified by a supplemental type certificate (STC) that installs Honeywell traffic alert and collision avoidance system (TCAS) 7.1 processor, part number (P/N) 940-0351-001.
(1) Model A318-111, -112, -121, and -122 airplanes.
(2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Model A320-211, -212, -214, -216, -231, -232, -233, -251N, and -271N airplanes.
(4) Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes.

(7) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
(8) Model A340-211, -212, and -213 airplanes.
(9) Model A340-311, -312, and -313 airplanes.
(10) Model A340-541 airplanes.
(11) Model A340-642 airplanes.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes; all Model A330-200 Freighter, -200, and -300 series airplanes; and all Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of false traffic collision avoidance system (TCAS) resolution advisories. This AD requires modifying the software in the TCAS computer processor or replacing the TCAS computer with a new TCAS computer. We are issuing this AD to address the unsafe condition on these products.
(1) For the purposes of this AD, Group 1 airplanes are those that have a Honeywell TPA-100B TCAS P/N 940-0351-001 processor that was installed during production, or in-service using the procedures in the applicable service information identified in paragraphs (g)(1)(i) through (g)(1)(xii) of this AD.

(x) Airbus Service Bulletin A340-34-4254.
(xi) Airbus Service Bulletin A340-34-5076.
(xii) Airbus Service Bulletin A340-34-5087.
(2) For the purposes of this AD, Group 2 airplanes are airplanes that do not have a Honeywell TPA-100B TCAS P/N 940-0351-001 processor installed.
For Group 1 airplanes, as identified in paragraph (g)(1) of this AD: Within 12 months after the effective date of this AD, do a modification of the TCAS processor to upgrade the software, or replace the TCAS processor with a TCAS TPA-100B processor having P/N 940-0351-005, in accordance with the Accomplishment Instructions of the applicable service information identified in paragraph (i) of this AD.
Note 1 to paragraph (h) of this AD: Guidance for modifying an affected TCAS processor and re-identifying the processor as P/N 940-0351-005 can be found in paragraph 3.F. of Honeywell Service Bulletin 940-0351-34-0005, dated January 20, 2017.
Use the applicable service information specified in paragraphs (i)(1) through (i)(5) of this AD to accomplish the actions required by paragraph (h) of this AD.
(1) For Model A318 and A319 series airplanes; Model A320-211, A320-212, A320-214, A320-216, A320-231, A320-232, and A320-233 airplanes; and Model A321 series airplanes: Airbus Service Bulletin A320-34-1656, Revision 01, dated September 6, 2017.
(2) For Model A320-251N and Model A320-271N airplanes: Airbus Service Bulletin A320-34-1657, Revision 01, dated September 6, 2017.
(3) For Model A330-200, A330-200 Freighter, and A330-300 series airplanes: Airbus Service Bulletin A330-34-3342, Revision 01, dated November 13, 2017.
(4) For Model A340-200 and A340-300 series airplanes: Airbus Service Bulletin A340-34-4304, dated April 19, 2017.
(5) For Model A340-500 and A340-600 series airplanes: Airbus Service Bulletin A340-34-5118, Revision 01, dated September 12, 2017.
An airplane on which Airbus modification 159658 or Airbus modification 206608, as applicable, has been embodied in production and on which it can be positively determined that no TCAS processor has been replaced or modified on that airplane since its date of manufacture is a Group 2 airplane, as identified in paragraph (g)(2) of this AD. Group 2 airplanes are not affected by the requirements of paragraph (h) of this AD. A review of airplane maintenance records is acceptable to make this determination, provided those records can be relied upon for that purpose and that the TCAS processor part number and software standard can be positively identified from that review.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
