Course DescriptionsAVIA120 Ground Operation and ServicingCredits: 2Prerequisites: noneThis course introduces servicing and ground operations ofaircraft and covers the choice and identification of fuels forboth reciprocating and turbine engine-powered aircraft and thenecessary precautions to observe when fueling an aircraft. Sinceawareness of ground operations and hazards is emphasized inthis section, the student is also introduced to “Safety in the Shopand on the Flight Line.” This increment also covers the properprocedure for starting reciprocating and turbine engines andthe procedures for proper engine run-up, aircraft movement,and tie-down.AVIA125 Maintenance Publications/Forms and Records/Mechanic Privileges and LimitationsCredits: 2Prerequisites: noneThis course introduces the importance of understandingthe regulations governing aviation maintenance and theinformation furnished by the aircraft, engine, and componentmanufacturers, and it emphasizes the importance of the legalaspects of aviation maintenance. The student will learn how toproperly describe the work done to an aircraft and must be ableto make the proper maintenance record entries, and explainthese records and forms step-by-step to what is expected of themechanic by the aircraft owner and what is allowed by the FAA.AVIA130 Basic AerodynamicsCredits: 2Prerequisites: noneThis course introduces knowledge of basic aerodynamics, whichdeals with the motion of air and the forces acting on bodiesmoving relative to the air. In the study of aerodynamics, thestudent learns about why and how an airplane flies. Althoughaerodynamics is a complex subject, exploring the fundamentalprinciples which govern flight is the main challenge inunderstanding what makes an airplane fly and begins withlearning the four forces of flight, which are lift, weight, thrust,and drag.AVIA135 Assembly and Rigging/Airframe InspectionCredits: 3Prerequisites: noneThis course introduces knowledge of the correct assemblyand rigging of an aircraft, which is vital to safe and efficientflight. This section explains the relationship between aircraftrigging and the aerodynamics of flight. The course alsointroduces how to determine the legal airworthiness of anaircraft, its powerplant, and components. The student willlearn the inspection aspects from a legal standpoint in whichthe emphasis is placed on the practical aspects and performanceof required inspections.AVIA140 Sheet MetalCredits: 3Prerequisites: noneThis course introduces knowledge of sheet metal structures,which is one of the most important types of modern aircraftconstruction. This section gives students a solid lesson in thetypes and materials for metallic aircraft structures, a discussionthat includes the stresses on aircraft structure and the strengthof various metal materials. The student is taught to installconventional, special rivets and fasteners; hand form, layout,and bend sheet metal; and to inspect and repair sheet metalstructures.AVIA145 Composites and PlasticsCredits: 3Prerequisites: noneThis course introduces knowledge of nonmetallic compositestructures, which is the second most important type of modernaircraft construction. This section gives students a solid lesson inthe types of composite materials and their manufacture details,a discussion that includes the foundation for the understandingof “Nonmetallic Aircraft Structures” and “Composite StructureInspection and Repair.”AVIA150 Wood StructuresCredits: 2Prerequisites: noneThis course introduces aircraft wood structures; the student willlearn and be able to identify defects and the different kinds ofwoods suitable for their application, describe the kinds of gluesand gluing techniques, and to restore old aircraft that have woodwing spars, ribs, and plywood structures.AVIA155 Aircraft Covering/Aircraft FinishesCredits: 2Prerequisites: noneThis course introduces the student to the application andmaintenance of fabric covered aircraft. They will learn abouthow a fabric covering is properly attached to aircraft structures.The student will become familiar with the different types ofcovering materials that are used to cover an aircraft plus thedope fillers, paints, and rejuvenator finishes used on the fabric.AVIA160 WeldingCredits: 3Prerequisites: noneThis course introduces the knowledge of welding, which isimportant because modern structures are so complex andhighly stressed that welding is usually a specialized type ofrepair done under highly controlled conditions. This sectionconcludes the discussion of Metallic Aircraft Structures with adetailed description of the types, tools, materials, and methodsof welding for aircraft construction, maintenance, and repair.88 2011 - 2012 Academic Catalog UM-Helena College of Technology
