Course Description

Materials used in aircraft, cleaning of parts, hardware and other fastener identification, and aircraft welding. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

1. Identify and select correct hardware and materials for installation on aircraft.
2. Identify different types of corrosion and determine correct method for corrosion removal treatment and prevention.
3. Demonstrate the ability to solder, braze and weld aircraft materials.

Course Objectives

• 1. Determine the correct length of bolts
• 2. Demonstrate the correct procedure to install bolts with castle nuts and bolts with self-locking nuts and torque to correct valves.
• 3. Identify the various family groups of aluminum alloy by visual recognition of code designators
• 4. Identify appropriate alloys for five specified aircraft applications.
• 5. Identify the SAE code markings and, referring to the SAE or AISA publications, and interpret the coding for ten samples.
• 6. Identify each rivet by head shape, alloy, dimensions, and where applicable, type letter designating strength characteristics
• 7. Identify various samples of materials suitable for use in aircraft firewalls and exhaust shrouds. He/She will use pertinent technical reference information or aircraft manuals to illustrate the suitability of the materials.
• 8. Identify six different samples of aircraft control able as to type of cable, number of strands, number of wires per strand, materials, and whether preformed or non-preformed.
• 9. Identify samples of aluminum alloys, at least five of which are considered heat-treatable, five nonheat-treatable, and three with trademarks indicating surface corrosion prevention treatment.
• 10. Will explain the steps in heat treatment of aluminum alloys, including the effect of heating a metal such as steel slightly above its critical temperature, then cooling it rapidly,
• 11. Will explain strain hardening and its effect on the tensile strength of aluminum alloy.
• 12. Demonstrate how to anneal a piece of copper tubing and how to stress relieve a welded steel part
• 13. Inspect and evaluate the quality of the weld in each of ten welded aircraft assemblies.
• 14. Identify heat treatable and weldable aluminum alloys.
• 15. Demonstrate the proper use of the cleaning operation with the proper precautions while cleaning aircraft components.
• 16. Select and employ the correct materials and clean the exterior surfaces of an airplane.
• 17. Select those parts which indicate intergranular corrosion. He/She will describe the methods of preventing and/or controlling this type of corrosion.
• 18. Evaluate corrosion such as metal flake, scale powder and salt deposits. They will describe how the corrosion should best be removed and the part then be treated from further corrosion.
• 19. Remove corrosion products, such as metal flakes, scale, powder and salt deposits from aluminum parts. He/She will describe how parts are protected from dissimilar metal corrosion.
• 20. Apply paints and/or similar organic coatings to aircraft parts.
• 21. Demonstrate cleaning and protecting battery compartments and adjacent areas by neutralizing the acid, removing corrosion, and applying acid-proof paints.
• 22. Identify "fretting" corrosion.
• 23. Describe the methods of protecting the interior of steel tubing and demonstrate the use of blast cleaning methods.
• 24. Explain the preparation of metal for soldering, brazing and welding, preheating prior to welding and the precautions regarding welding over previously brazed or soldered joints.
• 25. Demonstrate soldering electrical wires or cables to solder type connectors, sweat-soldering lap-joints of brass, tinned steel and stainless steel.
• 26. Identify and select parts which he considers repairable by welding. He/She will set up an oxy-acetylene welding set, clean and prepare steel parts for welding, and use the welding set to repair the steel parts by welding. He/She will make a similar repair appropriate to the damaged area selected. He/She will preheat the parts, select correct size tip and adjust an oxy-acetylene torch for correct type flame, select and use filler rod; perform welding of the steel parts and normalize them.
• 27. Identify ten welded splices, joints and sleeve repairs in tubing and tubular welded clusters. He/She will inspect ten samples of aircraft welded tubular structures and list whether each selected weld meets return-to-flight standards as specified in FAA publications.
• 28. Explain the use of silver brazing for stainless steel bonding,
• 29. Demonstrate how the metal should be prepared, what brazing tools to use, required brazing temperatures, and methods of cleaning after silver brazing.
• 30. Explain the method of cleaning magnesium for welding, the function of flux, the types of gases to use the use of butt joints when welding magnesium, and the methods of welding titanium.
