The affected cables were delivered after 1 January 2006.\n- Affected cables in stock must also be returned and are not to be installed on an aircraft.\n- Replacement timing: replace the affected cable at the first 1,200 flight-hour inspection after installation, but in any event no later than 30 April 2008. The AD became effective on 14 February 2008.\n\n**Why it matters (safety trigger and background)**\n\n- During production testing a batch of these control cables showed cracks inside the cable terminal. Although the cables met strength requirements at delivery, there is a risk their mechanical properties could degrade in service. The directive is intended to remove that risk by taking the suspect parts out of service.\n\n**Who it affects and who decides**\n\n- Who must act: aircraft operators and maintenance organisations that operate the specified Dornier 228 models and/or hold stock of the listed cable part number/batch.\n- Who issues the requirement: the Civil Aviation Safety Authority (via its delegate) issued the AD and sets the compliance deadline.\n- Who pays: the AD text does not state who bears replacement costs. Practically, costs fall on whichever party (operator, owner or manufacturer under commercial arrangement) arranges the removal, shipping back to RUAG and installation of replacements. The directive mandates return to the manufacturer but does not in itself allocate financial responsibility.\n\n**Practical effects and compliance actions required of operators**\n\n- Operators must inspect their maintenance records and physical stock to identify the EASA Form One number RS52074/05 or the batch number 1141044 on the fork end.\n- Any affected cable found installed must be removed at the stated inspection interval or by the final date. Cables held in stock must be sent back and must not be installed.\n- Operators will need to schedule the removal/replacement work into existing maintenance checks; there is an operational cost in parts, labour, paperwork and aircraft downtime.\n\n**Implementation issues, incentives and trade-offs**\n\n- Identification: the AD provides two clear ways to identify affected parts (EASA Form One number or batch number printed on the fork end), which reduces ambiguity but requires physical inspection of parts or paperwork.\n- Timing: the 'first 1200 flight-hour inspection after installation but no later than 30 April 2008' creates a binding deadline; parts recently installed could be subject to near-term removal, increasing short-term maintenance demand.\n- Enforcement and compliance burden: the AD introduces a discrete compliance task for operators and maintenance organisations (record checks, part tagging/withdrawal, shipping). That is a direct compliance cost and requires administrative/maintenance scheduling.\n- Financial incentives and allocation of costs are not specified. If the manufacturer bears replacement costs under warranty or commercial agreement, operators' direct expense will be reduced; if not, operators will incur parts and labour costs and potential downtime.\n- Market effects: the measure restricts the ability of operators to use certain stocked parts (temporary reduction in usable spare inventory). It imposes modest transaction costs (returns logistics) and potential short-run maintenance capacity effects for operators of the affected models.\n\n**Summary statement**\n\n- The AD is narrowly targeted: remove and return a specific batch of rudder control cables for Dornier 228 aircraft because of detected terminal cracks, and replace them within a short, specified timeframe. The directive defines how to identify the affected items, prohibits their installation, and sets a clear compliance deadline. The law shifts immediate costs and operational disruption to operators unless separate commercial arrangements with the manufacturer allocate those costs differently."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a targeted safety directive addressing a specific manufacturing defect in a specific aircraft part.
