The preliminary airworthiness evaluation of the OH-58D helicopter was conducted in Arlington, TX. The test required 56 flights for a total of 57 hours, of which 42.8 hours were productive. Handling qualities and vibration tests were conducted. The OH-58D in its present configuraion is unsuitable for single pilot instrument meteorological conditions flight. Two enhancing characteristic were identified and concerned the capability to change pilot displays and switch prepogrammed radio frequencies without removing either hand from flight controls. Two deficiencies were identified: the warning displayed on the multifunction display masked the altitude display; and the copilot cyclic stick could be engages while misaligned with the pilot's cyclic stick which would severely restrict cyclic travel. Additionally, 19 shortcomings and 5 instances of specification noncompliance were found.
