The directive names which serial-numbered aircraft are covered and makes action in Socata Mandatory Service Bulletin SB 70-038-24 (February 1994) and its Erratum (June 1994) compulsory for those aircraft (Requirement; Applicability).\n\nWho it affects and who decides:\n\n- Affected parties are owners/operators of Model TBM 700 aeroplanes with serial numbers 1–22 and 24–91 inclusive (Applicability). The Civil Aviation Safety Authority issues this airworthiness directive and requires compliance (header: Schedule of Airworthiness Directives).\n\nWhat operators must do and by when:\n\n- Operators must perform the work described in Socata TBM 700 Mandatory Service Bulletin SB 70-038-24 and the associated Erratum, unless they have already done so (Requirement). The work must be completed within 100 hours time in service after 8 December 1994 (Compliance).\n\nWhy the action is required (official rationale) and how that compares with practical effects:\n\n- The stated purpose is to prevent corrosion developing on the ground power receptacle shunt attaching screws (Background). Mechanically, complying means inspecting/altering/repairing the shunt attachment per the service bulletin, which affects maintenance tasks, parts used, and time the aircraft is unavailable.\n\nCosts, incentives and trade-offs (source-grounded):\n\n- Who pays: owners/operators must bear the direct costs of labour, any replacement parts, and the opportunity cost of aircraft downtime required to carry out the service (Requirement; Compliance).\n- Incentives: compliance lowers the risk of corrosion-related failure of the ground power receptacle shunt (Background), which can reduce future repair costs or operational disruptions. The directive creates a compliance incentive by making the service mandatory for the listed serial numbers (Requirement).\n- Trade-offs and opportunity costs: time spent completing the service consumes maintenance resources and aircraft availability that could be used for other work. Operators must prioritise allocating those resources within the specified 100-hour window (Compliance).\n\nCompliance burden and discretion:\n\n- Compliance burden is centred on carrying out the specific manufacturer service bulletin and erratum; the AD does not set alternative methods in the text itself (Requirement). That means operators must follow the SB details unless another approved method exists elsewhere (the AD text does not provide alternate approvals). The AD imposes a clear deadline for compliance (Compliance), leaving limited discretion about timing beyond the 100 hours requirement and limited discretion about whether to perform the SB (it is mandatory unless already done).\n\nImplementation risks and dependencies:\n\n- The directive depends on an external manufacturer document (SB 70-038-24 and Erratum) for technical instructions; if parts, tooling, or technical clarification from the manufacturer are delayed or unclear, that creates an implementation risk (Requirement).\n- The AD also references a related foreign airworthiness directive (DGAC AD 94-112(B)) but does not change the technical requirement set by the Socata service bulletin (Note).\n\nNet effect in practice:\n\n- Designated TBM 700 aircraft must undergo the manufacturer-prescribed maintenance action on the ground power receptacle shunt within the stated time window. The direct consequences are maintenance cost and aircraft downtime paid by operators, and a reduction in the risk of corrosion at the specified attachment points as stated by the AD (Requirement; Compliance; Background)."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, targeted safety directive focused on a specific mechanical defect in a specific aircraft model range. It has not expanded beyond its original purpose of mandating a corrosion-prevention fix."},"complexity_factors":["Very short document (approximately 150 words)","Only 4 defined elements: applicability (serial number range), requirement (reference to external service bulletin), compliance deadline, and background","No nested conditional logic or exceptions","Single cross-reference to French aviation authority (DGAC) directive for context only","Straightforward command structure: 'Unless previously accomplished, do X by Y date'"],"plain_english_summary":"This is an **Airworthiness Directive (AD)** — essentially a mandatory safety order issued by Australia's Civil Aviation Safety Authority (CASA) for specific aircraft.\n\n**What it does:**\nOrders owners and operators of certain Socata TBM 700 aeroplanes to carry out a specific maintenance fix. The fix involves following instructions in a manufacturer service bulletin (SB 70-038-24) to prevent corrosion on screws that attach the ground power receptacle shunt — a component that helps manage electrical grounding when the plane is plugged into external power on the ground.\n\n**Who it affects:**\nOwners and operators of TBM 700 model aeroplanes with serial numbers 1–22 and 24–91 (serial number 23 is excluded for some reason, likely already modified or different configuration).\n\n**Why it matters:**\nCorrosion on these screws could compromise the electrical grounding system. In aviation, faulty grounding can lead to electrical failures, sparks, or fire hazards. This AD ensures the problem is fixed before it becomes dangerous.\n\n**Key deadlines:**\nThe work must be done within 100 hours of flight time after 8 December 1994.\n\n**The bottom line:**\nIf you own one of these specific TBM 700 planes, you must get this corrosion-prevention work done by a qualified mechanic following the manufacturer's instructions, and you have a limited flight-hour window to comply."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt","history":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt/history","analysis":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt/analysis","conflicts":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt/conflicts","importantCases":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt/important-cases","documents":"/api/acts/ad-tbm-700-6-ground-power-receptacle-shunt/documents"}}
