Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C1 and AS332L1 helicopters. This AD was prompted by a report that the affected helicopters use the same "flight/ground" logic signal, instead of independent redundant signals. This AD requires amending the emergency procedures of the existing rotorcraft flight manual (RFM) for your helicopter, a wiring modification of the "flight/ground" logic signal source of the attitude and heading reference system (AHRS) 1, and then removal of the amendment to the existing RFM for your helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
