The Army Preliminary Evaluation APE of the Hughes Tool Company - Aircraft Division HTC-AD prototype Model 369C OH-6C helicopter was conducted at the Hughes facility in Culver City, California. A total of 34.6 productive flight hours were accumulated during the period 26 August to 22 September 1971. Engineering flight tests were conducted to evaluate the performance, handling qualities, and contractor-proposed flight envelope and to provide data for future use in the evaluation of the HTC-AD New Initiatives - Aerial Scout Program proposal. The data indicate that, in comparison with the OH-6A, the Hughes Model 369C can hover out of ground effect on a 35 C day at 4000 feet with a 207-pound increase in payload. The Model 369C can achieve a maximum level flight airspeed of 141 knots calibrated airspeed KCAS with a 660-pound payload - an increase of 14 percent over the 124-KCAS never-exceed velocity of the OH- 6A.
