Think of it like a compulsory recall notice, but for aircraft parts.\n\n**What it does:** It requires owners and operators of specific **Eurocopter AS 332 Super Puma helicopters** to inspect or fix a problem with the **main rotor head sleeves** — the metal fittings that connect the rotor blades to the helicopter's hub. The affected part numbers are 330A31 1376.04 and 330A31 1376.16.\n\n**Who it affects:** Anyone operating the C, C1, L, or L1 versions of these helicopters that have these specific sleeves installed.\n\n**What must be done:** Operators must follow the technical instructions in a French aviation safety document (DGAC AD 86-121-025(B) Revision 1, dated 19 September 1990). There's also a reference to an Aerospatiale Service Bulletin (SB 05.09 R3) for guidance.\n\n**Why it matters:** Main rotor head failures can be catastrophic. This directive ensures potentially defective sleeves are identified and addressed before they cause an accident.\n\n**Compliance:** The work must be done according to the timeline and procedures set out in the referenced French directive."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD adopts the technical requirements of DGAC AD 86-121-025(B) Revision 1 for specified AS 332 variants fitted with two listed sleeve part numbers.
