Job Task Planning and Organizing
  • Aircraft mechanics and aircraft inspectors organize their daily job tasks to accomplish the work assigned to them by supervisors and schedulers. They are generally assigned one work order at a time but may be required to plan tasks for multiple repair jobs and to ensure the efficient use of labour, parts and equipment. Aircraft mechanics and inspectors working in line maintenance departments are frequently required to modify job task plans to perform and inspect repairs to aircrafts that are unexpectedly grounded due to serious mechanical faults. Mechanics and aircraft inspectors may organize the activities of apprentices and helpers to ensure tools and equipment are used properly and that regulations established by employers, manufacturers and certifying bodies are followed. (2)

Decision Making
  • Decide to replace, refurbish and repair parts. For example, aircraft mechanics decide to replace parts that are worn beyond allowable specifications. (1)
  • Select the parts, tools, and equipment required to perform tasks and the order in which repairs are carried out. Consider the scope of repairs, manufacturers' specifications, the availability of parts and equipment, and procedures established by regulatory bodies. (2)
  • Select the service, reporting and inspection procedures required for various types of repairs. Consider your own certification levels, types of repairs being performed and the regulations and protocols established by employers, regulatory bodies and manufacturers. (2)
  • Decide to issue airworthiness certificates as appropriate. For example, aircraft maintenance engineers consider the results of repair and maintenance activities and the dangers posed by deficiencies before allowing aircraft to fly. They may allow aircraft to fly with known deficiencies if no danger is posed to safe operations. (3)
Back to Top

Problem Solving
  • Deal with incorrectly completed and inadequately documented repairs. For example, aircraft inspectors may inform co-workers and supervisors that repairs will not be certified until completed properly. Aircraft mechanics report documentation problems to supervisors and restart their work once the required documentation is available. (1)
  • You are unable to complete and inspect repairs because data such as specifications and instructions are unavailable. Consult with service managers, co-workers, suppliers and colleagues for advice and research websites to locate useable information. (2)
  • You are unable to meet repair and inspection deadlines due to scheduling changes and heavy workloads. Ask supervisors to prioritize repairs, enlist the help of co-workers and work overtime to complete high priority work. (2)
  • You have to delay jobs due to equipment breakdowns and lack of parts. Inform supervisors of the delays and carry out other work until equipment repairs are completed and the needed parts arrive. (2)
