What to do
Operators of affected Leonardo helicopter models must perform a one-time scissor coupling and axial play inspection within 25 flight hours or 3 months after 21 March 2022. Repetitive qualitative and quantitative axial play checks must be conducted at specified intervals not exceeding 50 and 200 flight hours respectively. Any failed inspections require corrective actions including part replacements within defined timeframes. Inspection results must be reported to Leonardo within 30 days after the initial inspection.
Summary
EASA Airworthiness Directive 2022-0037 is a safety directive affecting Leonardo S.p.A. helicopters including models A109E, A109LUH, A109S, AW109SP, A119, and AW119MKII. It mandates inspections of the main rotor rotating scissor assembly components to detect excessive axial play and potential ball bearing dislodgement. The directive provides detailed inspection and corrective action procedures to ensure continued airworthiness of these helicopter models.
What changed
EASA Airworthiness Directive 2022-0037 introduces a one-time and repetitive inspection regime for the main rotor rotating scissor assembly on specified Leonardo helicopter models. It corrects a previous note reference in Table 2 and clarifies inspection intervals, corrective actions, and reporting requirements. The directive also defines groups of helicopters with different compliance timelines and inspection criteria.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to loss of helicopter control due to failure in the main rotor rotating scissor assembly. Operators and maintenance organizations must comply to prevent possible damage and injury. The inspections and corrective actions ensure the reliability and safety of the affected helicopter fleet, impacting maintenance planning and operational readiness.
