What to do
Operators of AS 332 L2 helicopters with the affected part installed must inspect the yaw control damper support attachment points within specified flight hour limits and at intervals not exceeding 825 flight hours. If cracks are found, the affected part must be replaced with the reinforced serviceable part before the next flight. Installation of the affected part is prohibited from the effective date of 7 April 2021.
Summary
EASA Airworthiness Directive 2021-0086 is an airworthiness directive addressing the Airbus Helicopters AS 332 L2 model. It mandates inspection and replacement requirements for the yaw control damper support, specifically part number 332A25-1334-00, to prevent structural failure and potential loss of yaw flight control.
What changed
This directive supersedes EASA AD 2014-0080 and retains its inspection requirements while introducing mandatory replacement of any cracked yaw control damper support with a reinforced serviceable part, part number 332A07-2820-7071. It also prohibits the installation of the affected part on any helicopter from the effective date.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk involving cracks in the yaw control damper support that could lead to loss of yaw control. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent potential accidents caused by structural failure of the damper support.
