Abstract
For the past two decades filter debris analysis (FDA) has been used as a diagnostic technique to ascertain information about the wear state of CH124 main gearboxes (MGB) and turbine engines. Two FDA technologies, which optimize sample prepration and eliminate analyst variability were evaluated for first-line filter debris analysis capability for the CH124 Sea King helicopter. 1. FilterCHECK, which backwashes the filter, running the fluid through a sensor which simulataneoulsy counts and sizes metallic wear particles. 2. Intelligent Debris Analyzer (IDA), which optically counts, sizes, and determines the morphology of metallic wear particles. The Intelligent Debris Analyzer (IDA) was an accurate FDA analysis tool but was found to be sensitive to the operator and its environment. Therefore, the IDA is an unlikely candidate for first-line FDA. The FilterCHECK was observed to be an accurate filter debris extraction and analysis tool for use by the first-line maintenance technicians. Therefore, FilterCHECK should be field trialed to further assess its design, operation and operator training requirements.
