If an end fitting fails in service, it could cause loss of engine control.\n\n**Who pays, who decides, and what behavior changes**\n\n- Aircraft operators bear the cost and downtime of inspecting serial/batch numbers and replacing affected cables according to the Service Bulletin. Maintenance organisations carry out the replacement per the SB or an LBA‑approved revision.\n- The regulator (Civil Aviation Safety Authority delegate) mandated the action through the AD; the Service Bulletin determines the technical procedure.\n- Operators must check installed cable batch numbers and, if affected, remove and replace the cables by the next scheduled C‑Check.\n\n**Implementation mechanics and dependencies**\n\n- Compliance requires: (a) checking aircraft and cable records or physical inspection to confirm the batch number; (b) performing the replacement following the referenced Service Bulletin; and (c) using a later revision only if it is LBA‑approved.\n- The AD cross‑references an earlier LBA AD (2002‑252) and defers to LBA approvals for later SB revisions, which creates a dependency on foreign authority approvals for any future SB changes.\n\n**Costs, incentives and trade‑offs**\n\n- Direct costs: purchase of replacement cables (if supplied by manufacturer or authorised supplier), labour, and aircraft downtime around the next scheduled C‑Check.\n- Timing trade‑off: the AD allows deferral until the next C‑Check, which reduces immediate grounding risk but concentrates work at scheduled maintenance (possible opportunity cost of using C‑Check capacity earlier than planned).\n- Supply risk: if replacement cables are scarce, operators may face longer downtime or need sourcing from alternate suppliers.\n- Concentrated benefits and costs: the safety benefit accrues directly to operators and their passengers/crew (reduced risk of engine‑control failure); costs are concentrated on those operators of affected serial numbers. Parts suppliers that sell replacements will see increased demand.\n\n**Implementation risk and compliance burden**\n\n- Verification burden is modest but precise: maintenance staff must confirm part number and batch number.\n- There is limited regulator discretion in the AD itself (it prescribes replacement and points to a Service Bulletin). However, future changes to the SB require LBA approval.\n\n**Relevant AD text references**\n\n- Applicability: specific Dornier 328‑100 serial numbers and two affected cable batch numbers.\n- Requirement: replacement per Dornier SB‑328‑76‑409 Rev 1 or later LBA‑approved revision.\n- Compliance time: not later than the next scheduled C‑Check after the AD effective date.\n- Background: destructive tests identified cracks in end fittings; possible loss of engine control if not corrected.\n\n(Prepared as an analyst's note describing mechanisms, costs and implementation implications.
