    Study Notes

    Troubleshooting

    • Involves avionic LRU changes, but not multiple changes unless in accordance with a published approved maintenance procedure (e.g. Troubleshooting Manual, Fault Isolation Manual procedure)

    Type-Rated Aircraft

    • Defined as a particular type, or type and model, of large aircraft with a particular type of aircraft engine
    • Examples: Airbus A310 fitted with General Electric (GE) CF6 engines, Boeing 747-400 fitted with Rolls Royce (RR) RB211 engines
    • Small aircraft with a particular type of aircraft engine: PWC PT6 or Honeywell TPE331

    Type-Rated Aircraft Licence

    • Aircraft engineer licence that authorises certification of maintenance on specific types of (type-rated) aircraft
    • Training for the rating delivered by a maintenance training organisation in accordance with a course plan approved by CASA

    Aircraft Types

    Large Aircraft

    • Defined as:
      • Fixed-wing: MTOW > 5700 kg, or specified in Part 42 MOS as a large aircraft
      • Rotary-wing: more than one engine, or specified in Part 42 MOS as a large aircraft
    • Examples: Airbus A310, Boeing 747-400

    Small Aircraft

    • Defined as:
      • Fixed-wing: MTOW ≤ 5700 kg, and not specified in Part 42 MOS as a large aircraft, or > 5700 kg and specified in Part 42 MOS as a small aircraft
      • Rotary-wing: one engine, and not specified in Part 42 MOS as a large aircraft, or more than one engine and specified in Part 42 MOS as a small aircraft
    • Examples: PWC PT6 or Honeywell TPE331

    Primary Category Aircraft

    • Simple design, intended for pleasure and personal use only
    • Meet the description defined in CASR 21.024
    • Qualified pilot-owner can perform preventive maintenance only on a primary category aircraft

    Standard Category Aircraft

    • Operating under a Standard Certificate of Airworthiness (CofA)
    • Applicants not required to comply with an AMC, but can propose alternative ways to meet CASR requirements

    Guidance Material

    • Provides explanations and amplification of CASR policy intention
    • Should be read in conjunction with applicable CASR and AMCs
    • Identified by grey shaded text

    Aircraft Engineer Licence

    • Issued in one or more of the following categories: Category A, Category B1, Category B2, Category C
    • Categories A and B1 may be endorsed with subcategories for maintenance on combinations of aeroplanes, helicopters, and turbine and piston engines
    • Examples of subcategories: A1 and B1.1 aeroplane turbine, A2 and B1.2 aeroplane piston, A3 and B1.3 helicopter turbine, A4 and B1.4 helicopter piston

    Licence Privileges

    Category A Licence Privileges

    • Perform maintenance certification for subcategory maintenance if:
      • Carried out the maintenance, and
      • Maintenance is line maintenance of a kind mentioned in Appendix II of the Part 145 MOS
    • Issue a CRS for subcategory maintenance if:
      • Maintenance was carried out by that person, or
      • Maintenance and its maintenance certification were carried out by another person who holds a Category A licence with the appropriate subcategory, and
      • Maintenance was line maintenance of a kind mentioned in Appendix II of the Part 145 MOS, and
