Summary
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. Model A109S helicopters. This proposed AD is prompted by a report of a cabin liner detaching from the helicopter and hitting the main rotor (M/R) blades during flight. This proposed AD would require adding limitations to the rotorcraft flight manual (RFM). The proposed actions are intended to prevent an unsafe condition on these products.
