The duties and responsibilities of the Aviation Special Processes Technician are wide-ranging and the task of identifying duties common to most technicians in the industry was a challenging one. The Occupational Standard attempts to define the scope of these tasks and the required knowledge and abilities to perform them to the level of a qualified practitioner.
The main duties of an Aviation Special Processes Technician consist of the following: cleaning and stripping components and materials using chemical, electrical and mechanical processes; surface treatment of components and materials such as conversion coating, deposition, plating, thermal spray, diffusion coating and etching; shot, glass and flap peening processes and heat treatment such as hardening and stress relief and furnace brazing.
Aviation Special Processes Technicians are thoroughly familiar with the principles of chemistry and have extensive knowledge of safety requirements, as well as rules and regulations that apply to their work.
To qualify for certification with CCAA, the applicant must possess the necessary knowledge and skills and have acquired a minimum of twenty-four (24) months in the occupation. In addition, the applicant must also demonstrate a minimum of six (6) months experience in each of the appropriate specializations and sub-areas for specialization.
The four (4) main areas of specialization are:
- Cleaning / Stripping
- Surface Treatment
- Heat Treatment
The tasks in the logbook were made as generic as possible to accommodate the largest amount of work environments and equipment / tools but do not necessarily cover all tasks performed by individuals.
