Description
Summary:Tests were conducted to (1) determine the suitability of the YAC-1DH Carbon airplane for Army use under arctic winter conditions; (2) determine whether it has any deficiencies or shortcomings which should be corrected in the production models; and (3) determine the suitability of the T62-T-7 turbine auxiliary power unit (APU) as installed in the YAC-1DH. The YAC-1DH Caribou (test airplane) is a twin-engine, high-wing, utility transport-type airplane. Results indicate that the test airplane was satisfactory with respect to operating characteristics, flight and performance characteristics, tactical suitability, and maintenance at the temperatures encountered (32F through -35F). The T62-T-7 turbine was satisfactory as an APU and engine preheat unit. It was recommended that the YAC-1DH airplane be considered suitable for Army use after correction of the deficiencies and shortcomings which are noted.
