(Requirement)\n- The work must be done before 30 June 2002. (Compliance)\n\n**Which aircraft are affected**\n\n- All Airbus A319, A320 and A321 series aircraft that have PPG Aerospace windshields with the part numbers listed in the AD (NP-165311-1 through NP-165311-6) and a serial number listed in Airbus AOT A320-56A1010 Revision 1. (Applicability)\n\n**Why this is required**\n\n- Airbus investigated a windshield breakage on an A320 and found the cause was abnormal overheating of an internal power lead. The overheating was caused by damage to that power lead at the windshield manufacturer’s facility. The AD implements Airbus’s recommended corrective action to remove suspect windshields before another failure occurs. (Background)\n\n**Who must act and who pays**\n\n- Aircraft owners/operators are required to carry out the removal, scrap the suspect parts, and install replacement windshields according to the Airbus AOT. They bear the direct costs of parts, labour, aircraft downtime and any associated operational disruption. (Requirement)\n\n**Who decides how it is done**\n\n- The Civil Aviation Safety Authority (CASA), through the delegated AD, mandates compliance; the technical steps and approved replacement procedure are defined by Airbus AOT A320-56A1010 Revision 1. The AD also cross‑refers the French DGAC AD for the same issue. (Requirement; Note)\n\n**Practical effects on operators (behavioural and economic effects)**\n\n- Operators must inspect fleet records against the serial‑number list in the Airbus AOT, remove any matching windshields, destroy them (scrap), and fit approved replacements.\n- This may cause aircraft to be taken out of service for maintenance and could require expedited procurement of replacement windshields, affecting scheduling and costs.\n- The safety benefit is concentrated (reduces risk of windshield failure on affected aircraft); the cost is borne by operators whose aircraft contain the listed serial numbers.\n\n**Implementation and compliance risks / trade‑offs**\n\n- If replacement parts are not immediately available, operators may face grounded aircraft or short‑term schedule disruption.\n- There is an operational cost (parts + labour + downtime) and a recordkeeping burden (confirming serial numbers against the AOT list).\n- The AD relies on the Airbus AOT for the exact serial numbers and replacement instructions; any ambiguity or delay in that AOT could slow compliance. (Requirement; Applicability)\n\n**Source’s stated purpose and how it is delivered mechanically**\n\n- The stated purpose is to correct an unsafe condition identified after a windshield breakage due to internal overheating. The AD achieves that by mandating removal and destruction of windshields with affected serial numbers and replacement per the Airbus AOT, with a fixed compliance deadline.
