It addresses a specific technical maintenance requirement for a specific aircraft type's safety system.

Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires owners and operators of **Fairchild (Swearingen) SA226 and SA227 series aeroplanes** to inspect and/or modify their **Stall Avoidance System** (a safety device that warns pilots when the plane is at risk of stalling — losing lift and potentially crashing).\n\n**Specific requirements:**\n- **Who must comply:** Anyone operating these specific Fairchild aircraft models\n- **What to do:** Follow the instructions in **FAA Airworthiness Directive 85-22-06 R1** (the US aviation safety authority's equivalent order — Australia is adopting it here)\n- **When:** Within **100 hours of flight time** after 24 January 1991\n\n**Why it matters:** Stalls are dangerous. This system gives pilots early warning to prevent accidents. The directive ensures this critical safety equipment is working properly.\n\n**Key point:** This is a **reference directive** — it doesn't spell out the technical steps itself, but points to the US FAA document for the actual procedures."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive, as written, stays within the original airworthiness-control scope: it applies to the listed SA226/SA227 models (as defined in the Requirement Document) and requires inspection/modification in accordance with FAA AD 85-22-06 R1 within a specified 100‑hour window. There is no text in this instrument that expands or narrows the technical or regulatory scope beyond adopting the FAA AD and specifying the compliance timeframe.
