Progress continued this month on the NASTRAN model of the forward cabin. Some program slippage was experienced in both the mass distribution and updating cabin stiffness. The transmission and sponson geometry definition was reassigned to the CAD group and new commitments from the weights group were obtained. The program should be back on schedule by April 15. Screening of sensitive dynamic components has also been started. Overall expenditures are about 18% of budget at this point. Although light, the charges are expected to rise as the NASTRAN model of the aft fuselage is generated. This will have to be a complete new model unlike the forward cabin which is a modified CH-53E model. (Author)
