The directive appears to address a safety issue where these rods need additional protection (likely from damage, corrosion, or interference).\n\n**Who it affects:**\n- Owners and operators of Piaggio P166 aircraft with **serial numbers prior to 359**\n- Maintenance organisations servicing these aircraft\n\n**Why it matters:**\nEngine control failures are potentially catastrophic. If the Teleflex rods fail or become damaged, the pilot could lose the ability to control engine power — a critical safety risk during flight. This directive mandates a fix \"forthwith\" (immediately), indicating CASA considers this an urgent safety issue.\n\n**Compliance:**\nThe directive references **Piaggio Change Order No. 66-1** — this is the manufacturer's official technical instruction for making the required modification. \"Forthwith\" means operators must comply immediately, not at the next scheduled maintenance."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The text of the directive sets a clear, limited scope: Piaggio P166 aeroplanes with serial numbers prior to 359 must comply with Piaggio Change Order No. 66-1 forthwith.
