Appendix 5 APPENDIX 5. ADDITIONAL COURSE MATERIAL RECOMMENDATIONS The introduction of new aerospace technologies and maintenance requirements have imparted the knowledge, skills, and abilities required of AMTSs. A number of AMTSs have developed course materials to instruct students in emerging disciplines. Although the current regulations do not require it, a significant number of AMTSs are establishing these courses to satisfy industry demands. Following are some examples of courses offered in emerging areas:
1. Composite Material Repair. A composite repair course can be as simple as teaching fiberglass repair using prepackaged student instruction kits available from various sources, or as complex as a full-scale repair facility. Full-scale composite repair facilities teach and repair many types of composite materials, such as fiberglass, Kevlar, boron, and carbon materials.
Instructional aids and shop equipment can include clean rooms, downdraft worktables, positively vented rooms, composite autoclaves, refrigerated material storage, and various aircraft composite structures for instruction. Some AMTSs offering composite repair courses combine a nondestructive inspection course along with the basic course.
2. Nondestructive Inspection. A nondestructive inspection course that teaches beyond the requirements of part 147 (for example, magnetic particle) generally includes training in radiography (x-ray), ultrasound, eddy current inspection, and borescope techniques. Information on and equipment for nondestructive inspection course development are widely available from commercial sources.
3. Solid-State Electronics/Avionics/Built-In Test Equipment. Many AMTSs currently offer extended training or stand-alone course work leading to an electronics subspecialty in addition to an FAA A&P mechanic certificate. Although the FAA does not grant certification in the subspecialties, many potential aviation employers are requiring AMTs to have this enhanced training. These courses may be incorporated into existing required AMTS courses, such as basic electricity and basic physics. Course material, curriculums, and laboratory and shop equipment are readily available from commercial sources.
4. Principles of Troubleshooting. Broad-based principles of troubleshooting are well known and may be available commercially or developed by the school. An AMTS should focus on logical approaches to solving common aircraft problems. An AMTS may also include hands-on workshops using simulated aircraft system malfunctions.
5. Human Factors. Human factors principles should be incorporated throughout an AMTS’s curriculum. Many training programs are available commercially. The FAA also maintains a list of human factors reference materials at http://www.faa.gov/avr/afs/.
