Airworthiness Directives; Kaman Aerospace Corporation

We propose to adopt a new airworthiness directive (AD) for Kaman Aerospace Corporation (Kaman) Model K-1200 helicopters. This proposed AD would require revising the ``Flight Limitations--NO LOAD'' and ``Flight Limitations--LOAD'' sections of the rotorcraft flight manual (RFM). This proposed AD is prompted by a report of certain flight maneuvers that may lead to main rotor (M/R) blade to opposing hub contact. The proposed actions are intended to prevent damage to the M/R flight controls and subsequent loss of control of the helicopter.
