Free AMT Aircraft Inspection & Troubleshooting Questions and Answers — Questions and Answers
Question 1: What is the purpose of a 100-hour inspection?
- Check radio frequencies
- Maintain logbooks
- Ensure continued airworthiness (Correct answer)
- Schedule fuel delivery
Correct answer: Ensure continued airworthiness
A 100-hour inspection is a comprehensive check required for aircraft that are used for hire or flight instruction, performed every 100 hours of flight time. Its purpose is to thoroughly examine the aircraft's systems, components, and structure to identify any wear, damage, or defects. This regular inspection is crucial for ensuring the aircraft's continued airworthiness and safe operation.
Question 2: What tool is used to check for cracks in metal surfaces?
- Borescope
- Compression tester
- Dye penetrant (Correct answer)
- Torque wrench
Correct answer: Dye penetrant
Dye penetrant inspection (DPI) is a widely used non-destructive testing (NDT) method for detecting surface-breaking defects like cracks, porosity, and laps in non-porous materials. A liquid penetrant is applied to the surface, allowed to dwell, then removed, and a developer is applied to draw the penetrant out of any flaws. This makes even minute cracks visible to the naked eye, ensuring structural integrity.
Question 3: Why are discrepancy logs important in aircraft maintenance?
- For crew entertainment
- To record maintenance tasks
- Track unresolved issues (Correct answer)
- Calculate fuel usage
Correct answer: Track unresolved issues
Discrepancy logs are crucial in aircraft maintenance for systematically documenting and tracking any identified faults, malfunctions, or issues that require attention. They ensure that all problems are recorded, assigned for resolution, and followed up on until they are corrected. This maintains a clear audit trail and contributes significantly to the aircraft's overall airworthiness and safety.
Question 4: What is borescope inspection typically used for?
- Inspect control cables
- Inspect interiors of engine parts (Correct answer)
- Apply lubricant
- Secure landing gear
Correct answer: Inspect interiors of engine parts
Upon arriving at a disaster scene, CERT members must first perform a scene size-up to assess the situation safely and effectively. This involves quickly evaluating the overall scope of the incident, identifying immediate hazards, determining the number of victims, and establishing a safe perimeter. This critical initial step ensures the safety of responders and guides subsequent actions.
Question 5: Which system provides real-time engine monitoring?
- Gyroscopic system
- Flight data recorder
- Engine monitoring system (Correct answer)
- Pitot-static system
Correct answer: Engine monitoring system
Turning off utilities like gas, electricity, and water during a disaster is a crucial safety measure. It prevents additional hazards such as gas leaks leading to explosions, electrical fires from damaged wiring, or water contamination. By proactively shutting off these services, CERT members help protect lives and property from further harm and facilitate safer rescue operations.
Question 6: How should a mechanic handle a recurring issue during inspections?
- Ignore if minor
- Perform root cause analysis (Correct answer)
- Delete from logs
- Ask pilot to monitor
Correct answer: Perform root cause analysis
CERT members are trained to assist professional responders by performing light-duty tasks that do not require specialized equipment or extensive training. Suppressing small fires, such as those in wastebaskets or involving minor spills, is within their scope of training and helps prevent escalation of hazards before professional fire services arrive. This capability is vital for immediate hazard mitigation in a disaster.
Question 7: What should a mechanic check during a pre-flight inspection?
- Flight plan
- External damage and fluids (Correct answer)
- Passenger weight
- Catering supplies
Correct answer: External damage and fluids
A pre-flight inspection is a critical safety check performed by mechanics or pilots before an aircraft takes off. It involves visually inspecting the aircraft for any signs of external damage, such as dents or cracks, and verifying fluid levels (oil, hydraulic fluid, fuel) to ensure all systems are operating correctly and safely for flight. This proactive check helps prevent potential malfunctions or failures during operation.
Question 8: Why is torque wrench calibration important?
- It prevents theft
- Ensures accurate tightening (Correct answer)
- Tracks weather changes
- Monitors flight speed
Correct answer: Ensures accurate tightening
Torque wrenches are precision tools used to apply a specific amount of rotational force (torque) to a fastener. Calibration ensures that the wrench measures and applies this force accurately. In aviation, accurate tightening is vital to prevent fasteners from being too loose (leading to failure) or too tight (causing material damage), thereby maintaining structural integrity and safety.
Question 9: What is the purpose of a pitot-static system check?
- Fuel efficiency
- Pilot communication
- Check navigation database
- Ensure accurate airspeed/altitude (Correct answer)
Correct answer: Ensure accurate airspeed/altitude
The pitot-static system is a crucial aircraft instrument system that provides data for the airspeed indicator, altimeter, and vertical speed indicator. A system check verifies the integrity and accuracy of these instruments, which rely on air pressure differences. Ensuring their accuracy is paramount for safe navigation and flight control, as pilots depend on this information to maintain correct flight parameters.
