What to do
Operators of affected AS 332 L1 helicopters must replace the affected toggle switch support parts within six months of the directive's effective date. Operators of EC 225 LP helicopters must modify and re-identify the affected parts within the same timeframe. After compliance, installation of any affected parts is prohibited. All actions must follow the instructions in the applicable Airbus Helicopters Alert Service Bulletins.
Summary
EASA Airworthiness Directive 2023-0172 is an official safety directive addressing Airbus Helicopters AS 332 L1 and EC 225 LP models. It focuses on the replacement or modification of the cabin hoist shear toggle switch equipped support to prevent unsafe conditions during hoisting operations. The directive applies to specific serial numbers of these helicopter models.
What changed
This new directive introduces mandatory replacement of affected hoist shear toggle switch supports on AS 332 L1 helicopters and modification plus re-identification of these parts on EC 225 LP helicopters. It requires operators to follow Airbus Helicopters Alert Service Bulletins for the replacement or modification procedures. The directive prohibits installation of any affected parts after compliance.
Why it matters
This directive addresses a safety risk where the hoist operator's helmet cord can entangle with the toggle switch, potentially causing unintentional activation of the hoist cable cutter and in-flight release of external loads. Compliance ensures continued airworthiness and operational safety during hoisting operations. Operators, maintenance organizations, and compliance teams must act to mitigate this risk and avoid unsafe conditions.
