The directive mandates initial detailed and repetitive inspections to detect cracks caused by corrosion under residual stress, which could lead to part failure and loss of helicopter control.
What changed
EASA Airworthiness Directive 2020-0199 introduces mandatory inspections for the rotating and non-rotating scissors fittings on the main rotor hub and swashplate guide of Cabri G2 helicopters. It requires an initial detailed inspection within 30 flight hours or 30 days and repetitive visual inspections every 50 flight hours or 6 months, along with corrective actions if cracks are found.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could result in loss of helicopter control. Operators and maintenance organizations must comply to ensure continued airworthiness and safety of Cabri G2 helicopters. Failure to detect and correct cracks in the affected parts could lead to serious safety risks and regulatory non-compliance.
