minimise the risk of injury to self and others
prevent damage and wastage of goods, equipment and products
maintain required production output and product quality.
Complete failure analyses on a minimum of three different light marine transmission systems with real or simulated multi-system and intermittent faults and identify, evaluate, select and document the most appropriate rectification measure.
Analyse and validate or recommend variations to a minimum of two available repair/modification procedures for different light marine transmission systems.
Document and report the diagnostic process and findings and recommended rectification for the above.

Context of, and specific resources for assessment
Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.
Access to a requirement and objective(s) for analysis and evaluation, light marine transmission systems with real or simulated faults, monitoring processes and testing equipment appropriate to the objective(s), research facilities and technical information and a work environment.
Method of assessment
Assessment of this unit of competence is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may include certification of compliance of the final outcome/product or authorisation for use by a competent authority.
Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other circumstances.
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.
