AD FAA-2020-0454

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD was prompted by a report of vibrations around the 12Hz frequency due to the specific helicopter configuration. This AD requires removing the removable parts of the dual hoist installation or removing the de-icing system. This AD also allows, for certain helicopters, revising the Rotorcraft Flight Manual (RFM) for your helicopter and installing a placard as an optional method of compliance. The FAA is issuing this AD to address the unsafe condition on these products.
