The directive mandates inspection and corrective actions to ensure continued airworthiness.

What changed

This directive introduces a one-time inspection requirement for the affected fuel supply hose on EC 225 LP helicopters and specifies corrective actions if defects are found. It also establishes installation requirements for the affected part and the left hand side engine to prevent improper installation. The directive is considered an interim measure pending further action.

Why it matters

This directive is critical for aviation professionals as it addresses a potential in-flight engine power loss that could compromise helicopter control. Operators and maintenance organizations must comply to ensure safety and regulatory adherence, preventing incidents related to fuel supply hose defects. Compliance helps maintain aircraft airworthiness and operational reliability.
