This directive makes compliance with French DGAC AD 93-131-051 (B) R1 mandatory for Eurocopter AS332 C/C1/L/L1 helicopters fitted with epicyclic module P/N 332A32-2007-00 or -01. It requires operators to follow the referenced French corrective actions after discovery of over‑length bolts that may contact the second‑stage planet gear, so affected aircraft must be inspected/rectified to mitigate gearbox risk.
