What to do
Operators of Airbus Helicopters SA 330 J must inspect all affected pyrotechnical cartridges within three months of 2025-11-04 or within six months of the last resistance check, whichever is sooner, and repeat inspections every three months. Any cartridge found with discrepancies must be replaced before the next flight. Installation of affected parts is only allowed if the part is serviceable and has passed inspection within seven days prior to installation.
Summary
EASA Airworthiness Directive 2025-0231 is an airworthiness directive addressing the inspection of pyrotechnical cartridges used in the fire protection system of Airbus Helicopters SA 330 J helicopters. It mandates repetitive inspections of specific pyrotechnical cartridges identified by part and serial numbers to ensure their proper function in activating engine fire extinguishers. The directive applies to all serial numbers of the SA 330 J helicopter model.
What changed
This new airworthiness directive introduces mandatory repetitive inspections of affected pyrotechnical cartridges installed on SA 330 J helicopters. It requires operators to inspect these parts within three months of the effective date or six months since the last resistance check, and then every three months thereafter. If discrepancies are found, the affected cartridges must be replaced before further flight.
Why it matters
This directive is critical for aviation professionals because it addresses a potential failure in the engine fire extinguisher activation system, which could lead to insufficient fire suppression and risk to the helicopter and its occupants. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in unsafe conditions and regulatory penalties.
