Read the passage below:
Aviation hydraulic fluid must be regularly sampled and tested for particulate contamination using optical particle counters. When microscopic metal shavings or elastomer fragments exceed allowable ISO cleanliness codes, they cause accelerated spool valve erosion and seal degradation throughout flight control actuators. Rather than immediately flushing the entire hydraulic circuit upon detecting elevated particulate counts, maintenance technicians must first isolate specific sub-circuits using inline bypass sampling. This diagnostic isolation identifies whether component failure is localized to a single pump or widespread across the system, thereby preventing unnecessary fluid waste and reducing aircraft downtime.
Statement: The author's primary purpose is to explain the rationale behind isolating hydraulic sub-circuits during contamination troubleshooting before resorting to a complete system flush.
