What to do
Operators of Airbus Helicopters AS 332 C, C1, L, and L1 must perform inspections of the main gearbox suspension bar attachment fittings and screws within the compliance time specified in the applicable Airbus Helicopters Alert Service Bulletin. If any corrosion or discrepancies are found, corrective actions must be completed before the next flight. Inspection results with discrepancies must be reported to Airbus Helicopters within 30 days.
Summary
EASA Airworthiness Directive 2019-0295 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Airbus Helicopters AS 332 C, C1, L, and L1 models. It addresses corrosion found on the main gearbox suspension bar attachment fittings and screws, which could lead to structural failure and detachment of the suspension bars. The directive mandates inspections and corrective actions to ensure continued airworthiness.
What changed
This directive introduces a one-time inspection requirement for the affected attachment screws and fittings on the main gearbox suspension bars of specified AS 332 helicopter models. It also requires corrective actions if discrepancies are found and mandates reporting inspection results to Airbus Helicopters. Additionally, it enforces the proper application of compound sealant during maintenance to prevent corrosion.
Why it matters
This directive is critical for aviation professionals as it addresses a potential safety risk that could lead to structural failure of key helicopter components. Operators and maintenance organizations must comply to avoid unsafe conditions that could result in in-flight failures. Compliance ensures the structural integrity of the main gearbox suspension system, thereby maintaining flight safety and regulatory adherence.
