Summary
We are adopting a new airworthiness directive (AD) for AHD Model EC135P1, P2, P2+, T1, T2, and T2+ helicopters. This AD requires repetitive visual inspections of the ring frame X9227 for a crack and, if there is a crack, replacing the ring frame before further flight. This AD is prompted by a fatigue crack in the ring frame. These actions are intended to detect a crack in the ring frame and prevent loss of the tail rotor and subsequent loss of control of the helicopter.
