Specifically, they must incorporate specific inspection schedules and \"life limitations\" (maximum usage limits before parts must be replaced or overhauled) from a particular document: the **Shorts SD3-60 Maintenance Programme, Revision 3 dated 22 January 1988**.\n\n**Who it affects:**\n- Owners and operators of all Short SD3-60 aircraft models\n- Maintenance organisations servicing these aircraft\n- Anyone responsible for keeping these planes airworthy\n\n**Why it matters:**\nThis directive ensures these aircraft are maintained according to the manufacturer's latest safety standards. The change from referencing the \"Maintenance Manual\" to the \"Maintenance Programme\" (which is Chapter 5 of that manual) clarifies exactly which document contains the critical safety limits. \"Forthwith\" means compliance is required immediately — there's no grace period.\n\n**Key change in this version (Amendment 2):**\nThe directive originally pointed to the Maintenance Manual. This amendment updates the reference to point specifically to the Maintenance Programme document, which contains the airworthiness limitations. This is a technical clarification to ensure maintenance providers are looking at the right section of the documentation."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The amendment does not expand or narrow the set of aeroplane models subject to the Directive; it retains applicability to all SD3-60 models (Applicability). The substantive maintenance requirement — that the approved maintenance system include the listed inspections and life limitations — remains the same. The revision only changes the documentary reference from the Maintenance Manual to the separate Shorts SD3-60 Maintenance Programme (Background), which the Background notes forms Chapter 5 of the Maintenance Manual. Therefore the operational scope of the requirement is unchanged; the amendment clarifies which specific document operators must use (Background; Requirement)."},"complexity_factors":["Narrow applicability: applies only to Short SD3-60 series aeroplanes (Applicability).","Single, specific requirement: mandates inclusion of the inspections and life limitations from one named document (Requirement).","Immediate compliance timeline: no phased implementation or conditional dates, compliance is 'Forthwith' (Compliance).","Document-reference change: the amendment replaces a reference to the Maintenance Manual with the separate Maintenance Programme (Background), requiring operators to obtain and apply a particular revision (Rev 3, 22 Jan 1988).","Regulatory control point: relies on the operator's 'approved system of maintenance', implying oversight by the approving authority (Requirement; header)."],"plain_english_summary":"This Directive requires owners and operators of Short SD3‑60 aircraft to immediately incorporate the inspections and life‑limits listed in the Shorts SD3‑60 Maintenance Programme (Rev 3, 22 Jan 1988) into their approved maintenance systems.
