The old part (mechanical emergency jettison control P/N AS22-25) can cause the cargo hook to drop its load unexpectedly (\"uncommanded load jettison\"). It must be swapped for a redesigned part (P/N AS22-12).\n\n**Who it affects:**\n- **Aircraft:** Eurocopter AS 332 Super Puma models C, C1, L, and L1\n- **Specific equipment:** Only those fitted with a sling installation using a 3-ton cargo hook (Part Number AS21-7) AND the problematic emergency release control (P/N AS22-25)\n- **People:** Helicopter operators, maintenance engineers, and owners who use these aircraft for lifting external loads\n\n**Why it matters:** If the faulty part isn't replaced, the helicopter could accidentally drop whatever it's carrying — endangering people on the ground, damaging property, and potentially causing the helicopter to become dangerously unbalanced. This is a critical safety fix for external load operations.\n\n**Key deadlines:**\n- Original deadline: Before next use of the cargo hook after 27 July 1994\n- This amended version took effect: 10 November 1994\n\n**What changed in this amendment:** Just paperwork housekeeping — updating references to match the current version of the French aviation authority's directive (DGAC AD 94-150-052(B)R1) and adding a reference to the manufacturer's service bulletin (Eurocopter SB No. 01-38 R1).
