Study Notes

Tool Care and Control

Proper handling and care of tools reflect professionalism and attention to detail.
Keep hand tools clean, organized, and free from dirt and grease to ensure efficiency and longevity.
Store tools promptly in designated spaces within toolboxes to maintain order and prevent loss.

Tool Control Significance

Misplaced tools pose significant safety risks and can lead to costly foreign object damage (FOD).
The National Aerospace FOD Prevention Inc. estimates $4 billion in annual costs due to FOD in the aerospace industry, primarily from engine damage.

Tool Control Programs

Aircraft maintenance organizations implement Tool Control Programs to track tools from the moment they're used until they're returned.
Details of such programs may vary by workplace, but key components generally remain consistent.

Individual Toolboxes

Toolboxes should allow quick verification of tool presence at the end of a task, minimizing the potential for missing tools.
Custom foam inserts can indicate missing tools, revealing a contrasting color when a tool is removed, showcasing an efficient visual management method.

Shadow Boards

Shadow boards serve as visual management tools, promoting accountability among employees to report missing tools instead of replacing them.

Tool Inventory Practices

Conduct tool inventories regularly, ideally after each task or shift, to ensure all tools are accounted for.
Timely identification of missing tools is crucial for maintaining safety standards in aircraft maintenance.

Missing Tool Reporting

A clear and structured process for reporting missing tools is essential for safety.
Employees should be encouraged to report missing tools, with designated personnel responsible for addressing these issues.

Workshop Practices and Materials

Proper allowances and tolerances are crucial for ensuring the correct fit of mating cylindrical parts in aircraft components.
A positive allowance indicates clearances, whereas a negative allowance indicates interference, reflecting the importance of precise manufacturing tolerances.

Calibration of Tools

Regular inspection and calibration of precision tools is required in aircraft maintenance organizations.
Each tool should have clear labeling that details the last inspection date, next due date, and the signature of an authorized individual.

Dimensions and Tolerances

Aircraft drawings utilize a reference edge for dimensional accuracy, with dimensions traditionally presented either perpendicular or parallel to the drawing.
Tolerance defines the acceptable size range for components, underscoring the accuracy needed in engineering specifications.

Sheet Metal Working

Acceptable sizes for aircraft sheet metal components range between maximum and minimum limits, with sizing indicated in inches.
The double prime symbol (″) is used in drawings to denote inches, critical for accurate fabricating and dimensions.
