Summary
EASA Airworthiness Directive 2025-0146-E is an emergency directive affecting Airbus Helicopters AS 332 L, L1, L2, and EC 225 LP models. It addresses the inspection and possible replacement of the emergency sea anchor pin, part numbers 704A42695001 and 704A42695002, due to reported corrosion issues. The directive mandates inspections to prevent potential anchor failure that could lead to rotor damage and loss of helicopter control.
What changed
This new emergency airworthiness directive introduces mandatory inspections of the emergency sea anchor pin within 10 flight hours or 7 days after the effective date. If corrosion or defects are found, the affected part must be replaced or temporarily plugged with a locally made plug, which must be replaced with a serviceable part within six months. It also allows the installation of only serviceable parts from the effective date onward.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could result in catastrophic helicopter failure. Operators and maintenance organizations must ensure compliance to prevent in-flight anchor detachment, which could cause rotor damage and loss of control. Timely inspections and corrective actions are essential to maintain airworthiness and regulatory compliance.
