EASA SIB 2010-13

Mar 12, 2010

WITHDRAWN - Current status can be followed on the EASA SUP website: https://www.easa.europa.eu/en/domains/aircraft-products/suspected-unapproved-parts.

EASA Safety Information Bulletin SIB No. 2010-13 notifies operators and maintenance organizations about unapproved Main Gear Box (MGB) parts stolen from a EUROCOPTER subcontractor in Marseille, France. The affected parts include Bevel Gear Wheels (P/N M1157 to M1166) for EUROCOPTER AS 350, AS 355, and EC130 B4 helicopters, and Forward Reduction Gears (P/N M2793 to M2807) for EUROCOPTER AS 332 and EC225 LP models. These parts have completed manufacturing but lack final compliance checks and EASA Form One certification, rendering them unapproved for installation.
