This paper presents a summary of the airvehicle modifications (largely structural) that were made and the airworthiness qualification flight test program that was conducted to expand the operational gross weight capability and enhance the structural integrity of the subject helicopter. The impact on both vibration and dynamic component retirement times are discussed. The paper includes both technical and cost information to support program benefits of this modernization approach, but will address only the basic airvehicle, including its rotor/drive and propulsion systems. Discussion of special mission equipment peculiar to the special operational forces mission and most shipboard operations features, can not be included.
