simple test means a test described in maintenance data that meets all of the following criteria:
1. the serviceability of the system can be verified using aircraft controls, switches, built-in test equipment (BITE), central maintenance computer (CMC) or external test equipment not involving special training;
2. the outcome of the test is a unique go/no-go indication or parameter. No interpretation of the test result or interdependence of different values is allowed.
small aircraft has the same meaning as in the CASR Dictionary.
subsystem means a system which, while capable of functioning on its own, is part of a larger system and includes, for this MOS:
1. the electrical subsystem comprised of electrical parts, appliances and motors, within mechanical, powerplant and structural systems; or
2. the instrument subsystem comprised of avionic systems within mechanical, powerplant and structural systems.
this MOS means the Part 66 Manual of Standards.
troubleshooting means the published approved fault isolation maintenance procedures and actions outlined in maintenance data, used as necessary in order to identify the root cause of a defect or malfunction. It may include the use of BITE or external test equipment. Troubleshooting may involve avionic LRU changes, however, it does not involve multiple avionic LRU changes in pursuit of a system fault, unless the changes are made in accordance with a published approved fault isolation maintenance procedure (e.g. Troubleshooting Manual, Fault Isolation Manual procedure).
      (c) Unless the contrary intention appears, the term carry out maintenance includes, within its normal meaning, both the supervision of maintenance and carrying out the physical tasks of maintenance.

       66.6 Meaning of hold, or obtain, a unit of competency
