   2. Explain the purpose of flaps and describe how they improve aircraft performance during take-off and landing.
6. Aircraft Engines
   
   1. Describe the common types of aircraft engines (piston, turbo-prop, turbo-shaft, turbo-fan and turbo-jet) and explain the difference between a piston and turbine engine.
   2. Explain how a piston engine works using the four-stroke cycle: intake, compression, power and exhaust.
   3. Identify the following components on an aircraft or from diagrams, and explain the function of each:
      • Air filter
      • Carburettor
      • Engine-driven fuel pump
      • Magnetos
      • Oil filter
      • Spark plugs
   4. Explain the common types of aircraft fuel, what octane means, and why it is important.
7. Aircraft Systems
   Describe the difference between hydraulic and pneumatic systems and give two examples of where each is used on an aircraft.
8. Engine Controls
   1. Explain how the throttle, fuel mixture control, and propeller pitch control (where fitted) affect engine operation.
   2. Describe the common types of aircraft propellers (such as fixed-pitch and constant-speed) and explain how changing the propeller blade pitch in a constant-speed propeller affects engine performance.
9. Instrument Panel
   1. Explain the purpose of the fuel pressure, oil pressure, oil temperature and engine temperature indicator(s).
   2. Demonstrate where the engine instruments are located on an aircraft or instrument panel and correctly identify each instrument.
   3. Identify the primary flight instruments ('six pack') and distinguish them from the engine instruments.
   4. Explain how abnormal engine instrument readings can indicate potential engine problems and describe the importance of reporting or investigating these indications before flight.
10. Aircraft Inspection and Maintenance
    Visit an aircraft maintenance facility or maintenance hangar and, with the guidance of an aircraft engineer or suitably qualified person:
    1. Discuss how routine inspections and scheduled maintenance help keep aircraft safe and airworthy.
    2. Assist with cleaning and inspecting an aircraft, identifying items that would require further inspection or maintenance before flight.
    3. Demonstrate your understanding of a pre-flight inspection by accompanying a pilot during a pre-flight inspection and explaining what is being checked and why each step is important.
    4. Describe the importance of recording maintenance performed and inspections completed in the aircraft logbook and explain why only authorised persons may certify maintenance.
    5. Explain why locking wire (safety wire) is used to secure fasteners on an aircraft and describe how it helps prevent components from loosening in service.
    6. Demonstrate how foreign object debris (FOD) can damage an aircraft and describe the measures used to prevent it.
11. Airworthiness and Maintenance Responsibilities
    1. Explain the difference between type-certified and non-type-certified (experimental) aircraft.
    2. Explain why approved aircraft parts must meet recognised standards, be correctly documented, be traceable throughout their service life, and, where required, be sourced from an approved manufacturer or supplier.
    3. Describe why aircraft components and parts require regular inspection, servicing or replacement, and explain how maintenance intervals may be based on condition, calendar time, operating hours and/or operating cycles.
    4. Describe the routine maintenance tasks that may be carried out by a pilot and/or aircraft owner, and explain when maintenance must be performed by a suitably qualified aircraft maintenance engineer.
    5. Describe the role and responsibilities of the following aircraft maintenance specialisations. Explain the type of maintenance each is qualified and authorised to carry out, and why aircraft maintenance must only be performed by appropriately qualified personnel.
       • Airframe and Powerplant
       • Structures (Sheet metal and composites)
       • Electrical Systems
       • Instruments and Avionics

Recommended Age Range: The Air Mechanic Scout Interest Badge is recommended for Scouts aged 14 to 17 years. At this age, Scouts have the maturity to understand basic mechanical systems, safety procedures, and aircraft maintenance practices. The badge encourages practical problem-solving, teamwork, and career exploration without requiring the advanced technical knowledge expected of licensed aircraft engineers.

Badge Examiner: Training and examination for this badge must be conducted by a suitably qualified individual who has relevant experience or formal training in the specific field of expertise being assessed. The ideal examiner should be a licensed aircraft maintenance engineer (AME), aircraft maintenance technician (AMT), appropriately qualified aviation engineer, aircraft maintenance instructor, or an experienced aviation professional or Adult Leader with suitable aircraft maintenance knowledge and practical experience. Note to the Examiner:

• This is a Scout Interest Badge intended to introduce Scouts to the fundamentals of aircraft maintenance, safe working practices, and the importance of maintaining airworthiness. It is not intended to assess the knowledge or competency of a trainee aircraft maintenance engineer.
• The emphasis should be on the Scout's practical understanding, safe application of maintenance principles, and appreciation of how routine maintenance contributes to aircraft safety, rather than detailed engineering theory or professional-level technical knowledge.
• Wherever possible, Scouts should complete the practical requirements using a serviceable aircraft at an aerodrome or maintenance hangar, allowing them to gain hands-on experience under appropriate supervision. Where access to a serviceable aircraft is not available, suitable aircraft components, maintenance manuals, diagrams, models, photographs, or other training aids may be used to demonstrate and assess the required skills and knowledge.
• Practical activities involving aircraft or maintenance equipment should be conducted under the supervision of an appropriately qualified person and in accordance with the safety procedures of the maintenance facility or organisation being visited.
• Encourage the Scout to participate actively in demonstrations, discussions, and practical activities. Assess the Scout's ability to apply knowledge, explain maintenance practices in their own words, and demonstrate an understanding of why maintenance tasks are performed and how they contribute to keeping aircraft safe and airworthy.
