What is the location of the chip detector?

• A. Bottom of RGB
• B. Top of RGB
• C. Near the fuel pump
• D. Inside the engine compartment

Answer: (B)

The chip detector is strategically located at the top of the Reduction Gear Box (RGB). This position is critical because it allows the chip detector to effectively monitor the lubrication system for any metal particles that may indicate wear or damage within the gearbox components. By being situated at the top, the chip detector can efficiently collect debris that rises to the surface due to the motion of oil and the operation of the RGB, ensuring timely detection of potential mechanical issues. This is crucial for maintaining the overall operational integrity and safety of the aircraft.

In contrast, other locations such as the bottom of the RGB, near the fuel pump, or inside the engine compartment may not provide the same effectiveness in detecting metal chips and particles, as they could either miss debris due to settling or fail to monitor the specific gear mechanisms adequately.
