Summary
EASA Airworthiness Directive 2022-0209-E is an emergency directive addressing a potential fire hazard in Leonardo AB139 and AW139 helicopters. It mandates inspections of the harness installation in the forward roof area, specifically focusing on electrical cable routing, the collective torque tube, and diode components. The directive applies to specific serial numbers of AB139 and AW139 helicopters and aims to prevent electrical short circuits that could lead to fire and loss of control.
What changed
This new emergency airworthiness directive introduces mandatory one-time borescope and visual inspections of the forward cabin roof ceiling electrical harness installation. It requires corrective actions if incorrect cable routing, chafing, or damage to components such as the diode or torque tube is found. The directive also establishes reporting requirements for any discrepancies discovered during inspections.
Why it matters
This directive is critical for aviation professionals as it addresses a serious safety risk involving potential fire and loss of helicopter control. Operators and maintenance organizations must ensure compliance to prevent in-flight emergencies caused by electrical wiring damage. Timely inspections and corrective actions are essential to maintain airworthiness and regulatory compliance.
