Inspection When servicing or repairing the instrument, routinely begin with a visual
Techniques inspection of the hardware and components for signs of damage. Signs of
damage require further inspection of the surrounding area for peripheral
breakage or damage.
Exterior Inspection Visually inspect the entire instrument for wear, corrosion, deterioration, and
damage resulting from extreme temperatures or dropping. Lift and hold the
instrument upside down while listening for loose hardware.
Interior Inspection Table 4-1, Inspection Techniques, lists the major hardware components of
the instrument, possible problems associated with each item, and
recommended corrective actions.
