## Summary

We propose to adopt a new airworthiness directive (AD) for certain Agusta S.p.A. (Agusta) Model AW139 helicopters. This proposed AD is prompted by the discovery of improper installation of solder splices on the co-pilot audio system causing intermittent noise through the audio system during flight. The proposed actions are intended to prevent degradation and complete loss of communications between the pilot and co-pilot during flight, impairing the co-pilot's capability to react immediately to operational difficulties, which could lead to subsequent loss of control of the helicopter.
