The class surveyor will typically check the turbocharger's performance, vibration, and temperature, as well as inspect the compressor and turbine blades, bearings, and seals for signs of wear or damage. The surveyor will also verify that the turbocharger is properly installed, aligned, and maintained, and that all safety devices and alarms are functioning correctly.
