Action
Notice of proposed rulemaking (NPRM).
Summary
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.
