This self-paced, individualized course, adapted from military curriculum materials for use in vocational and technical education, teaches students the skills needed to become a qualified avionics worker and aircrew rescuer on the HH-3F helicopter. The course materials consist of four pamphlets: two student workbooks and two student syllabuses. The first pamphlet covers such subjects as rotary wing theory of flight, HH-3F familiarization, aircraft systems and communications. In order to give the student a thorough knowledge of the aircraft and systems in order to perform routine inspections and systems troubleshooting, the pamphlet includes the following aircraft systems: hydraulics, electrical, landing gear, wheel brakes, ramp, rescue hoist, auxiliary power unit, engine fire detection, heating, ventilation, anti-ice, and fuel. The second pamphlet concerns the HH-3F helicopter power train covering the main rotor assembly, transmission system, flight control system, and an in-depth study of the T58-GE-5 engine. These workbooks include reading assignments with student objectives, self-tests, and answers to the tests. The two student syllabuses contain material for the flight mechanic and for the hoist operator. (KC)
