SUPERSEDED BY EASA AD 2023-0076
Summary
EASA Airworthiness Directive 2023-0049 is an airworthiness directive issued for Airbus Helicopters AS 332 C, C1, L, and L1 models. It mandates inspection and measurement of the main gearbox suspension bar attachment plates to ensure correct installation and structural integrity. The directive addresses potential unsafe conditions caused by incorrect installation of attachment plates originally designed for other helicopter models.
What Changed
This new airworthiness directive introduces a one-time inspection and measurement requirement for the main gearbox rear and front suspension bar attachment plates on affected AS 332 helicopters. It requires operators to identify any discrepancies and, if found, to contact Airbus Helicopters for approved corrective actions before further flight. The directive also clarifies that these attachment plates can only be installed during D-level maintenance by Airbus Helicopters staff.
Why It Matters
This directive is critical for aviation professionals because incorrect installation of suspension bar attachment plates can lead to structural damage or failure of load-carrying elements, posing a safety risk. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid potential in-service failures. Compliance helps prevent costly repairs and ensures continued safe operation of the affected helicopter fleet.
What To Do
Operators of Airbus Helicopters AS 332 C, C1, L, and L1 must perform the required inspection and measurement of the main gearbox suspension bar attachment plates within 50 flight hours from 21 March 2023. If any discrepancies are found, they must contact Airbus Helicopters for corrective instructions and complete the repairs before the next flight. Compliance with Airbus Helicopters Alert Service Bulletin AS332-53.02.15 is mandatory.
