What to do
Owners, operators, and maintenance organizations should inspect their helicopter parts inventory for the specified MGB part numbers. If found, these parts should be quarantined immediately to prevent installation and EUROCOPTER should be informed without delay. No mandatory compliance deadline is specified, but prompt action is recommended to ensure safety.
Summary
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.
What changed
This bulletin introduces a notification regarding stolen and unapproved MGB parts intended for specific EUROCOPTER helicopter models. It informs stakeholders that these parts should not be installed due to missing conformity and certification. The bulletin does not amend previous regulations but serves as an advisory to prevent use of these suspect parts.
Why it matters
This information is critical for aviation professionals to ensure the safety and airworthiness of EUROCOPTER helicopters by preventing installation of unapproved and potentially unsafe MGB parts. Operators, maintenance organizations, and inventory managers must be vigilant to avoid using stolen parts that have not undergone required quality control and certification. Compliance helps maintain regulatory standards and reduces risk of mechanical failure.
