    Study Notes

    Workshop Practices

    • Learning objectives include describing the correct care of tools, control of tools, and use of workshop materials, as well as analyzing dimensions, allowances, and tolerances.

    Standards of Workmanship

    • Workmanship refers to the degree of skill with which a product is made or a job done.
    • Factors contributing to workmanship include:
      • The art of skill of a worker
      • The quality of the product
      • The product or result of the labor and skill of a worker

      • Symbols and abbreviations
      • Types of drawings (e.g., working drawings, exploded views, sectional drawings)
      • Methods of illustrating (e.g., orthographic projection, isometric drawings)
      • Title blocks and bills of material
      • Dimensioning and tolerancing
      • Manufacturers' publications and standards
    • Understanding engineering drawings and diagrams is essential for aircraft maintenance.

      • Cable systems and construction
      • Cable termination and inspection
      • Cable installation and adjustment
      • Turnbuckle locking and travel adjustment

    • Understanding aircraft control cables is crucial for aircraft maintenance.### Sealants

    • It is crucial to check the expiry date/shelf life before using a product to maintain its integrity.

    • After use, ensure the container is properly sealed to enable re-use at a later date.

    • Mixed two-pack sealants need to cure completely before disposal, and then they can be disposed of in accordance with local council/authority regulations.

    Dimensions, Tolerances, and Allowances

    • Aircraft drawings are dimensioned using a reference edge from which all dimensions are made.
    • Dimensions can be placed on an aircraft drawing in two ways: perpendicular to the dimension lines or parallel to the bottom of the drawing.
    • The nominal dimension of an aircraft part is the size stated on the drawing.
    • A part fabricated from aircraft sheet metal has a maximum and a minimum allowable size.
    • Tolerance is the difference between the nominal dimension and the upper and lower limits of size.

    Standards

    • Standards provide benefits to business and individuals, including accurate measurements, lowered production costs, improved product performance, and more.
    • There are three types of standards: private, national, and international.
    • National standards are produced by a country's National Standards Body (NSB) and are often enforced by regulation.
    • International standards are produced by the International Organisation for Standardisation (ISO).

    Tool Control

    • Tools are designed to make a job easier and enable efficient work, but they must be properly used and cared for.
    • Without the proper tools and knowledge of how to use them, time is wasted, efficiency is reduced, and injuries may occur.
    • Tools are expensive and vital equipment, and a little preventative maintenance can prolong their usefulness.
    • A clear procedure should be in place for reporting missing tools, including how often tools need to be inventoried and the steps to be taken once a missing tool is reported.

    Workshop Practices

    • Many types of workshop materials are available, including greases, oils, solvents, sealants, contact cements, paints, and paint strippers.
    • A Material Safety Data Sheet (MSDS) and a specification sheet should be available for all materials used in the workshop.

    Material Storage

    • Storage of flammable materials is crucial for safety and maximum usage.
    • Flammable materials should be stored in an appropriate flammable storage facility when not in use.
    • Some materials are highly toxic, and it is vital to comply with the MSDS for individual materials, including using PPE and working in a well-ventilated environment.
    • Many aircraft sealants require refrigerated storage to ensure they stay usable for their shelf life.
