ACS Troubleshooting Techniques & Inspection Standards 1 — Questions and Answers
Question 1: What is the first step in troubleshooting an aircraft system?
- Replace suspected parts
- Identify the problem (Correct answer)
- Disassemble the system
- Check battery voltage
Correct answer: Identify the problem
The first step is identifying the problem through observation or pilot reports.
Question 2: Which tool is commonly used to check continuity in electrical circuits?
- Caliper
- Multimeter (Correct answer)
- Torque wrench
- Rivet gun
Correct answer: Multimeter
A multimeter is used to check continuity and diagnose electrical faults.
Question 3: Which method is best for locating hydraulic leaks?
- Thermal imaging
- Visual and tactile inspection (Correct answer)
- X-ray scanning
- Ultrasonic testing
Correct answer: Visual and tactile inspection
Visual inspection and tactile checks are standard for detecting leaks in hydraulic systems.
Question 4: What standard must aircraft inspections comply with?
- Mechanic's experience
- FAA and manufacturer standards (Correct answer)
- Pilot's opinion
- Local weather reports
Correct answer: FAA and manufacturer standards
Inspections must comply with the manufacturer's instructions and FAA regulations.
Question 5: What type of inspection uses sound waves to detect material flaws?
- Dye penetrant inspection
- Ultrasonic inspection (Correct answer)
- Visual inspection
- Magnetic particle inspection
Correct answer: Ultrasonic inspection
Ultrasonic inspection uses high-frequency sound waves to detect flaws inside materials.
Question 6: Which part of the maintenance manual specifies troubleshooting steps?
- General Information section
- Troubleshooting section (Correct answer)
- Schematics section
- Parts Catalog section
Correct answer: Troubleshooting section
The Troubleshooting section of the manual provides step-by-step diagnostic guidance.
Question 7: How should discrepancies be documented during inspection?
- By verbal communication only
- In maintenance logbooks (Correct answer)
- On personal notes
- Only after repairs
Correct answer: In maintenance logbooks
All discrepancies should be clearly recorded in the maintenance records/logbooks.
Question 8: What is a borescope used for?
- Cleaning components
- Internal visual inspections (Correct answer)
- Removing corrosion
- Measuring airspeed
Correct answer: Internal visual inspections
A borescope allows internal inspection of engines and airframes without disassembly.
Question 9: Which method is primarily used to detect corrosion on aircraft structures?
- Visual inspection (Correct answer)
- Ultrasonic inspection
- X-ray imaging
- Magnetic field mapping
Correct answer: Visual inspection
Visual inspection is the first method to identify corrosion before using specialized tests.
