Summary
We are adopting a new airworthiness directive (AD) for Kaman Model K-1200 helicopters with certain main rotor blades (MRB) installed. This AD requires inspecting each MRB for a crack or damage. This AD was prompted by a report that a crack was found on an MRB during a tear-down inspection. The actions are intended to detect a crack in the MRB, which could lead to failure of the MRB and subsequent loss of control of the helicopter.
