Airbus Industrie A319, A320 and A321 Series Aeroplanes
AD/A320/145 Transformer Rectifier Unit 13/2002
Applicability: Airbus model A319, A320 and A321 series aeroplanes without Airbus modification 30737 incorporated during production or either Airbus Industrie Service Bulletin (SB) A320-24-1099 dated 5 March 2002 or A320-24-1099 Revision 1 dated 26 July 2002 embodied.
Requirement: 1. Replace the Kollmorgen Artus transformer rectifier unit (TRU) part number (P/N) Y005-2 installed in position 2 (1PU2) by TRU P/N Y005-3 in accordance with SB A320-24-1099 Revision 1.
2. TRU P/N Y005-2 may not be installed in position 2 (1PU2) as a replacement part.
Note: DGAC AD 2002-554(B) refers.
Compliance: For Requirement 1 - Either before 31 March 2004 or before the TRU has accumulated 15,000 hours’ time in service, whichever occurs later.
For Requirement 2 - After 31 March 2004.
This Airworthiness Directive becomes effective on 26 December 2002.
Background: The Direction Générale de l’Aviation Civile has received reports of smoke smells in the cockpit. Investigations have revealed that the smoke and/or smell is caused by the failure of the TRU input filter capacitors.
This Directive requires replacement of TRUs in position 2 (1PU2).

Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serve as the foundational regulatory framework governing civil aviation safety within the country. A specific legislative instrument within this broader act, the Airworthiness Directive (AD) issued on 18 November 2002, addresses an identified safety issue concerning the Airbus Industrie A319, A320, and A321 series aeroplanes. The directive aims to rectify an unsafe condition related to the transformer rectifier unit (TRU) by mandating the replacement of specific TRU components to prevent occurrences of smoke or smell in the cockpit, which had been traced to failures in the TRU input filter capacitors. This Airworthiness Directive was issued by the Civil Aviation Safety Authority (CASA) to ensure the continued airworthiness and safety of the specified aircraft models, aligning with the overarching policy objective of maintaining the highest standards of aviation safety in Australia.
Scope and Application
The Airworthiness Directive AD/A320/145 issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 (CAR 1998) applies specifically to Airbus Industrie A319, A320, and A321 series aeroplanes that do not have Airbus modification 30737 incorporated during production or Airbus Industrie Service Bulletin (SB) A320-24-1099 dated 5 March 2002 or its revision dated 26 July 2002 embodied. The directive mandates that the Kollmorgen Artus transformer rectifier unit (TRU) part number Y005-2 installed in position 2 (1PU2) be replaced with TRU part number Y005-3, as per SB A320-24-1099 Revision 1. Additionally, TRU P/N Y005-2 must not be installed in position 2 (1PU2) as a replacement part. The compliance requirement stipulates that the replacement must occur either before 31 March 2004 or before the TRU has accumulated 15,000 hours’ time in service, whichever is later, and TRU P/N Y005-2 must not be installed in position 2 (1PU2) after 31 March 2004. The AD became effective on 26 December 2002 and was notified in the Commonwealth of Australia Gazette on 4 December 2002.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the framework under which Airworthiness Directives (ADs) are issued by the Civil Aviation Safety Authority (CASA) (39.1(1)). This AD (AD/A320/145) targets Airbus Industrie A319, A320, and A321 series aeroplanes that do not have Airbus modification 30737 incorporated during production or have not implemented Service Bulletins (SB) A320-24-1099 dated 5 March 2002 or A320-24-1099 Revision 1 dated 26 July 2002. The directive mandates the replacement of the Kollmorgen Artus transformer rectifier unit (TRU) part number (P/N) Y005-2 installed in position 2 (1PU2) with TRU P/N Y005-3, as per SB A320-24-1099 Revision 1. Additionally, TRU P/N Y005-2 must not be reinstalled in position 2 (1PU2). The directive was issued in response to reports of smoke smells in the cockpit traced to failures in the TRU input filter capacitors.
Entities governed by this AD must adhere to specific requirements to maintain the airworthiness of their aircraft. For Requirement 1, the replacement of the TRU must occur either before 31 March 2004 or before the TRU has accumulated 15,000 hours of service, whichever comes later. For Requirement 2, TRU P/N Y005-2 must not be reinstalled in position 2 (1PU2) after 31 March 2004. Non-compliance with these directives may result in serious safety implications, potentially leading to operational restrictions or grounding of the affected aircraft.
Failure to comply with the AD’s requirements can lead to significant consequences. Although the Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with ADs, non-compliance may result in enforcement actions by CASA. Such actions can include fines, operational restrictions, or even the grounding of the aircraft until the necessary actions are taken. The severity of the penalties may depend on the extent of non-compliance and its impact on aviation safety. The AD became effective on 26 December 2002, and its implementation is crucial for ensuring the continued safe operation of the specified Airbus aircraft models.
