Non-Destructive Testing

Non-destructive testing (NDT) involves using advanced techniques to assess the integrity of the aircraft’s structure without causing damage. NDT methods include ultrasonic testing, dye penetrant inspections, and magnetic particle inspections. By utilizing NDT, technicians can identify internal flaws or defects that may not be visible during visual inspections.

Structural Integrity Checks

Structural integrity checks are comprehensive assessments of the aircraft’s structure to ensure it meets the necessary standards and regulations. These checks involve detailed inspections and testing of critical parts such as wings, fuselage, and landing gear. Technicians utilize specialized equipment and techniques to assess the structural integrity and identify any areas that require repairs or replacements.

Engine Inspections

The engines are the heart of any aircraft, and regular inspections are crucial to maintaining their performance and reliability. Engine inspections typically consist of oil analysis, borescope inspections, and engine performance monitoring.

Oil Analysis

Oil analysis is a proactive method of monitoring the health of the engine. By analyzing the oil, technicians can detect any abnormal wear patterns, contaminants, or other signs of engine degradation. Regular oil analysis allows for timely maintenance and addressing potential issues before they lead to major engine failures.

Borescope Inspection

Borescope inspections involve using a specialized instrument to visually inspect the internal components of the engine. Technicians insert the borescope into the engine through access points to assess its condition. This inspection allows for a detailed examination of critical engine components and early detection of any abnormalities or damage.

Engine Performance Monitoring

Engine performance monitoring involves collecting data during operation to assess the engine’s efficiency and performance. This data is analyzed to identify any deviations or potential issues that may require attention. By continuously monitoring engine performance, technicians can intervene before problems escalate and ensure the engines operate optimally.

Avionics Inspections

Avionics refer to the electronic systems and instruments that control and support the aircraft’s navigation, communication, and flight control. Avionics inspections are crucial to maintaining the functionality and accuracy of these systems. They typically include electrical system checks, flight control system checks, and instrument calibration.

Electrical System Checks

Electrical system checks involve assessing the aircraft’s electrical components and systems to ensure they are functioning correctly. Technicians inspect the wiring, circuit breakers, generators, and other electrical components to detect any issues that may affect the aircraft’s electrical system’s reliability and safety.

Flight Control System Checks

Flight control system checks are essential to ensure the aircraft can be maneuvered safely and efficiently. Technicians inspect the control surfaces, such as the ailerons, elevators, and rudder, to ensure they are properly aligned and functioning as intended. They also inspect the hydraulic and mechanical systems that control these surfaces to detect any potential failures or malfunctions.

Instrument Calibration

Instrument calibration is the process of verifying the accuracy of the aircraft’s instruments, such as altimeters, airspeed indicators, and navigation systems. Technicians use specialized tools and equipment to compare the readings of these instruments against known standards to ensure their accuracy. Proper instrument calibration is crucial for safe and precise flight operations.
