EASA AD US-2020-02-23

Feb 21, 2020

Equipment / Furnishings - Emergency Float Kit Pull Cables - Inspection

Federal Aviation Administration Airworthiness Directive 2020-02-23 is a final rule addressing certain Airbus Helicopters models AS350B series and AS355 series equipped with emergency float kits. It mandates repetitive inspections of the pull cable installation on the emergency float kits to ensure proper activation of the float inflation system. This directive aims to prevent asymmetric float inflation or failure to deploy, which could lead to capsizing during water landings.
