MODIFICATIONS

MODIFICATION CLASSIFICATION MAJOR 206608S34248 MINOR None NOTE : As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Unjustified Traffic Alert and Collision Avoidance System (TCAS) resolution advisory (RA) triggered with Honeywell TCAS TPA100-B PN 940-0351-001 have been reported. The unexpected RAs are triggered when two aircraft are crossing at the same flight level or are in vertical convergence but when conditions for RA generation are not satisfied. Usually, the unexpected RA is preceded by a very short TA (traffic advisory) and in some cases no aural TA is provided.

The duration of unexpected RA can be up to 1 minute.

The crew has then to comply with TCAS order that lead to unnecessary avoidance maneuvers.

This Service Bulletin is published to advise all operators of A340 aircraft family of the issue of HONEYWELL Service Bulletin No. 940-0351-34-0005.

This Service Bulletin replaces the TCAS (FIN 1SG) Honeywell TPA-100B change 7.1 PN 940-0351-001 installed with MOD 57609S30373 (Service Bulletin No. A340-34-5076 or Service Bulletin No.

A340-34-5087) by a new one PN 940-0351-005 which corrects unjustified resolution advisory with software changes.

The introduction of this new TCAS standard will include the following changes:

(2) Install the Traffic Collision Avoidance System (TCAS) Computer E. COMPLIANCE

(1) Classification MANDATORY: Service Bulletin must be accomplished.

(2) Accomplishment Timescale Accomplishment of this Service Bulletin shall be completed within 12 months from the issue date of this Service Bulletin.

This Service Bulletin has been classified Mandatory by the issue of an Airworthiness Directive (AD) published by the European Av iation Safety Agenc y (EASA). The AD must be used as the reference document for the mandated accomplishment timescale.

F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031.

If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin.

G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances.
