True or False: The drill guide must be assembled by threading the appropriate size bushing into it.

The statement that the drill guide must be assembled by threading the appropriate size bushing into it is true because the use of a bushing is essential for achieving precise drilling in aerospace assembly. The bushing serves as a guide that aligns the drill bit accurately with the workpiece, ensuring that holes are drilled to the correct diameter and depth, which meets strict tolerances required in aerospace manufacturing.

This assembly process is crucial due to the critical nature of aerospace components, where any misalignment or incorrect hole size can lead to serious implications for structural integrity and safety. The proper bushing ensures that the drill guide functions effectively, providing the necessary support and aligning features that are vital during the assembly process.
