Job Task Planning and Organizing
  • Aircraft instrument, electrical and avionic mechanics, technicians and inspectors generally receive their project assignments and priorities from their supervisors. Their ability to manage priorities and sequence tasks is critical for meeting deadlines. System malfunctions, instrument breakdowns and emergencies make frequent prioritizing and sequencing of job tasks necessary. They may work in teams during system overhauls. They integrate job tasks with co-workers when coordinating access to confined working spaces, testing equipment and tools. They plan and coordinate their testing tasks with resident pilots and air traffic controllers. Aircraft instrument, electrical and avionic mechanics, technicians and inspectors may be responsible for planning work assignments and training experiences for apprentices. (2)
Back to Top

Decision Making
  • Decide when to seek technical assistance and when to outsource testing and repairs. Consider the existing test results, experience, completion deadlines and the type of repairs. (2)
  • Choose materials and methods for carrying out troubleshooting and repair tasks. Set procedures are in place, but decide the order of troubleshooting and the sequence of tests based on knowledge of instruments, avionic equipment, and information from manuals and other documents. The ability to correctly decide which procedures to use is important to ensure project deadlines are met. (2)
  • Decide to replace defective parts, components and instruments. For example, when inspecting wiring, wire casings and analog instruments consider the external wear, flight hours, age of parts, stress indicators, replacement availability and cost and time constraints. When making replacement decisions, seek approval, as appropriate, on larger items and items that may delay the completion of jobs. (3)
  • Make decisions about aircraft instruments' and avionic equipment airworthiness. For example, avionic technicians choose to approve the airworthiness of repaired instruments and release them back into active use. They consider testing results, wear on instruments and flight hours. Avionic inspectors decide to approve installed aviation systems such as flight tracking systems after reviewing technicians' notes and comparing diagnostic and testing results to specifications and standards. Their decisions must always be correct to ensure the safety of passengers and crew members. (4)

Problem Solving
  • Replacement parts cannot be found when repairing instruments and avionic equipment. Identify alternative sources such as parts and equipment from grounded aircraft and unserviceable instruments. Consider the quality, wear, maintenance schedules and compatibility of the borrowed parts before requesting approvals from supervisors. (2)
  • Experience intermittent instrument and avionic equipment malfunctions. Systematically check all equipment readings, test results, flight logbook entries and previous maintenance records to isolate faults. For example, find loose components are creating vibrations, which are causing malfunctions. Request modifications to mounting structures to minimize vibrations. (3)
  • Apprentices are failing to meet work standards and expectations. For example, find that apprentices are failing to meet deadlines or not using the proper steps and procedures to complete work. Observe apprentices to identify problem areas, provide instructions and closely monitor their work until standards are achieved. (3)
  • Encounter lack of cooperation, which affects the work environment. For example, inspectors may encounter maintenance technicians who are unreceptive to their feedback. They ask their supervisors for suggestions and may take management and communication courses to improve their own skills to ensure interactions are more effective. (3)
Back to Top

Finding Information
  • Locate technical information such as testing and component specifications, operational tolerances, troubleshooting, repair and installation procedures and 'theory of operations' in data and maintenance manuals, service bulletins, troubleshooting checklists, flowcharts and decision trees. (2)
  • Consult co-workers who have expertise with particular instruments for information about repairing aircraft equipment and systems which are unfamiliar. (2)

Critical Thinking
  • Judge the functionality, ergonomics and safety of new instrument and equipment installations. Consider the layout on aircraft drawings, the function of the individual modules and the ease of access for future repairs. (Aircraft Instrument, Electrical and Avionics Mechanics, Technicians and Inspectors) (2)
  • Evaluate the usability of individual instruments, parts and components from grounded planes and unserviceable instruments for use in repairing other instruments. Gather information by reviewing past work orders, completing diagnostic testing and reviewing results. In addition, consider visible wear, age, flight hours and stresses which parts have been subjected. (Aircraft Instrument, Electrical and Avionics Mechanics, Technicians and Inspectors) (2)
  • Judge the quality and completeness of written work procedures. For example, when reviewing new testing and diagnostic procedures consider the tone and clarity of the language, the completeness of explanations for each step and specialized terms to make recommendations. (Aircraft Instrument, Electrical and Avionics Mechanics, Technicians and Inspectors) (3)
  • Evaluate the performance of co-workers and contractors. Assess the quality of their work by observing their attitudes and abilities to meet deadlines. The inspectors' judgments of employees' performance is critical to meeting required guidelines, specifications and standards. (Aircraft Instrument, Electrical & Avionics Inspectors) (3)
  • Evaluate the quality of mechanics' and technicians' work. Carry out visual inspections, read technicians' and pilots' notes in logbooks and on work cards and compare diagnostic test results to specifications and standards. (Aircraft Instrument, Electrical & Avionics Inspectors) (3)
  • Assess the usability of aircraft that have outstanding avionic repairs. Consider the importance of individual instruments and parts to the overall performance of flight systems and flights. Consider the number of faulty components and parts and their interdependence to the overall functioning and operability of the aircraft. Your expert judgement is critical when the sum of all faults will not necessarily ground a plane. Use your experience to recommend it be grounded or only used on limited flights. (Aircraft Instrument, Electrical and Avionics Mechanics, Technicians and Inspectors) (3)
  • Evaluate the performance of aircraft instrument, electrical and avionic systems. Gather information by taking measurements, reading flight logs, viewing test results, and talking to air crew. Analyze data such as test and diagnostic as part of the evaluation process. Your expert judgement is critical in an industry where concern for costs and safety are high.
