A wire harness (a bundle of electrical wires) has been rubbing against and damaging a hydraulic line that maintains pressure in the aircraft's systems. If left unfixed, this could cause the hydraulic line to fail, potentially leading to loss of aircraft control.\n\n**Who must comply:**\n- All AS 332 helicopters, specifically versions C, C1, L, and L1\n- **Unless** the helicopter has already been modified using specific Eurocopter service kits (AMS 332A 07.26.044 or kit No 332A.08.8133)\n\n**What action is required:**\nFollow the repair instructions in **Eurocopter France Service Bulletin AS 332 No 24.20** (dated 2 June 1992). This bulletin contains the technical steps to prevent the wire harness from interfering with the hydraulic line.\n\n**When it must be done:**\nWithin **300 flight hours** OR **3 months** from 15 October 1992 — whichever comes first.\n\n**Why it matters:**\nThis is a **flight safety issue**. Hydraulic system failure in a helicopter can be catastrophic. The directive forces operators to address a known design flaw before it causes an accident."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive's scope, as stated, is limited to preventing wire-harness interference with a pressurisation hydraulic line on specified AS 332 variants that have not already received the listed modifications.
