## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to AS332L2 helicopters. This action requires inspecting each main rotor head drag damper (damper) for a tear, crack, or bonding separation in the elastomer and, if necessary, replacing the damper with an airworthy damper. This amendment is prompted by a report of increased helicopter vibration in flight that was traced to the delamination of the elastomer on a damper. This condition, if not corrected, could result in failure of a damper and subsequent loss of control of the helicopter.
