(Requirement)\n- Directs operators to carry out that inspection following the procedures in Airbus Service Bulletin A330-56-3006. (Requirement)\n- Sets the deadline for compliance as \"within 6 months after 15 May 2003.\" (Compliance)\n\nWhich aircraft are affected\n\n- Only certain A330 serial numbers are covered: Model A330-202, -223, -243 and -343 with Manufacturing Serial Numbers 0396–0398, 0400, 0401, 0403–0405, 0407–0409, 0412, and 0418–0421. (Applicability)\n\nWhy the rule exists (stated reason)\n\n- The manufacturer found a risk that windshield central retainer bolts fitted at production might be too short to give safe nut engagement. The inspection is intended to detect and correct that condition. (Background)\n\nPractical effects, incentives and costs\n\n- Who pays: the aircraft operator or owner pays for the inspection and any corrective work (parts, labour, and aircraft downtime). (Requirement + Compliance)\n- Who decides: CASA (through its delegate) mandates the inspection; Airbus Service Bulletin A330-56-3006 provides the technical instructions operators must follow. Operators must apply the Service Bulletin to demonstrate compliance. (Requirement)\n- Behaviour change: affected operators must schedule and perform the inspection within the prescribed timeframe; if insufficient bolt engagement is found they must perform repairs or replacements as detailed in the Airbus service instructions. (Requirement)\n- Direct costs: labour hours, possible parts replacement, and loss of aircraft availability while maintenance is performed. The AD does not itself fund or supply parts. (Requirement + Compliance)\n- Compliance burden: the AD is narrowly targeted (specific serial numbers) and relies on an external service bulletin for procedure details, so the main administrative burden is identifying affected aircraft and booking maintenance per the SB. (Applicability + Requirement)\n- Implementation risk: effectiveness depends on the clarity and completeness of the Airbus Service Bulletin and the availability of suitable replacement parts or approved repair instructions if bolts are defective. (Requirement + Background)\n\nHow the instrument is limited and what it does not do\n\n- This AD does not impose any ongoing inspection program; it requires a single inspection action within the specified window. (Compliance)\n- It does not itself prescribe corrective action details beyond referring to Airbus Service Bulletin A330-56-3006, so the technical remedy follows the manufacturer's procedures. (Requirement)\n\nNotes on inter-governmental cross-reference\n\n- The AD references a related French DGAC airworthiness directive (DGAC AD 2003-123(B) R1) and states Amendment 1 was issued to align applicability with the DGAC revision. (Note / Amendment 1)\n\nSummary judgement about scope and trade-offs (analytical lens)\n\n- The measure concentrates costs on a defined group of A330 operators (those with the listed MSNs) while spreading the safety benefit to anyone using those aircraft. The regulatory action is specific and time-limited, reducing ongoing administrative costs but creating a near-term maintenance burden. The main implementation risk is operational (availability of maintenance capacity and parts) and depends on the content and execution of the Airbus Service Bulletin.
