Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for Kaman Aerospace Corporation (Kaman) Model K-1200 helicopters. This AD requires revising the "Flight Limitations--NO LOAD" and "Flight Limitations-- LOAD" sections of the rotorcraft flight manual (RFM). This AD was prompted by a report of certain flight maneuvers that may lead to main rotor (M/R) blade to opposing hub contact. These actions are intended to prevent damage to the M/R flight controls and subsequent loss of control of the helicopter.
