Course Description

Fundamental theory of assembly, cabin control systems, and rigging. Practical experience in rigging, assembly, disassembly, repair, overhaul, testing, inspection, and operation of component parts. ADVISORY: AMT A153. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

1. Rig aircraft flight controls on fixed wing and helicopters, balance controls surfaces, jack airplanes and assemble flight control components.
2. Inspect, check, troubleshoot, service and repair heating, cooling, air-conditioning and pressurization systems.
3. Inspect and check pneumatic power system components.

Course Objectives

• 1. Identify, and label the three axes of the aircraft.
• 2. Illustrate the displacement or motion of an airplane about each of the three axes.
• 3. Describe the aerodynamics forces action upon an airplane in flight.
• 4. Describe the design features which contribute to the stability of the airplane.
• 5. Illustrate the relationship between center of pressure and center of gravity at three different angles of attack. With the aileron and flap in various displaced positions, the student will illustrate the movement of the center of pressure of the airfoil.
• 6. Identify and select the required hardware (bolts, nut, screws, etc.) from an assortment or supply room. They will install, torque and safety these fasteners on the mock-up panel or in the assembly.
• 7. Recognize and explain the cause and effect of blade stall when helicopters are operating at high speed.
• 8. Recognize and explain the cause of vertical vibrations.
• 9. Recognize and explain the methods of tracking main rotor blades.
• 10. Recognize and explain the preparation required prior to rigging a rotorcraft.
• 11. Interpret information and make the measurements necessary to verify the alignment of landing gear, wings and fixed tail surfaces.
• 12. Install a nicopress sleeve and thimble at one end of the cable and a swaged fitting at the other end.
• 13. Install an elevator, rudder, or aileron cable, use a tensiometer to establish correct cable tension, safety all turnbuckles and attaching devices in accordance with the service manual.
• 14. Inspect the control systems of the airplane for cable wear, tension, pulley wear and rotation, swaged terminal slippage, turnbuckle safety, corrosion and control surface travel, and record discrepancies on a report form.
• 15. Interpret the manufacturers instructions, follow procedure and use equipment to check the unbalance of the control surface.
• 16. Inspect the bellcranks, push-pull tubes, rod ends, guides, adjust the travel of the movable control surfaces and safety the control systems in accordance with the service manual for that particular make and model of aircraft.
• 17. Accomplish a 100 hour or annual inspection of the airplane and evaluate conditions disclosed as a result of the inspection.
• 18. Solder electrical wires or cables to solder type connectors, sweat-solder lap-joints of brass, tinned steel and stainless steel.
• 19. Identify and select parts which they considers repairable by welding.
• 20. Perform welded bead seams on samples of aluminum alloy and stainless steel sheet.
• 21. Perform welding of the steel parts and normalize them.
• 22. Interpret information and explain the principles of pneumatics and the operation of the specific system.
• 23. Identify and label the major components of a freon vaporcycle cooling system.
• 24. Identify and label the major components of an air cycle cooling system.
