3.7 Overhaul Tools & Equipment
3.7.1 Tool & Gauge Control
Tool and gauge control is an important part of aviation maintenance systems. Tools and gauges must
be accu
rate enough for the intended use (i.e. you would not use a 12” steel ruler to measure the
cylinder bore diameter) and be accurately calibrated
– for example by an approved laboratory.
Calibrations must be kept up to date. This means a check calibration every year or more frequently for
regularly used, critical tooling.
Even quality equipment will wear over time so items like reams, go / no-go gauges and valve seat
cutting tools must periodically be checked to ensure they remain within limits.
