It applies to a specific type of aircraft: the **Aerospatiale (Socata) TBM 700 Series** with serial numbers 1 through 49.\n\n**What it requires:**\nOwners or operators of these aircraft must install **pneumatic de-icing equipment** on the \"elevator horns\" — small aerodynamic surfaces on the tail of the plane that help control pitch. Without this equipment, ice can build up during slow flight in icy conditions, potentially causing loss of control.\n\n**Who must act:**\nAnyone operating one of these 49 specific aircraft in Australia.\n\n**By when:**\nThe work had to be completed before **30 June 1993**.\n\n**Why it matters:**\nIce accumulation on control surfaces is a serious flight safety hazard. This directive prevents accidents by ensuring these particular aircraft have proper anti-icing protection on a vulnerable part of the tail."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD’s scope is stated explicitly in the source: it applies only to Aerospatiale TBM 700 aircraft with serial numbers 1–49 inclusive (Applicability) and requires installation of pneumatic de-icing equipment in accordance with Socata TBM SB 70-20-30 (Requirement), to be completed prior to 30 June 1993 (Compliance).
