uality assurance is the primary governing aspect of yourbusiness. When safety is paramount to your dailyoperation a condition monitoring program is an inherentpart of your procedures. Oil and wear particle analysis isthe most widely accepted method of condition monitoring,in use today, for aviation systems. It is no wonder whymost OEMs recommend, or insist, upon some form of oiland wear particle analysis.

il and wear particle analysis is a combination ofspectrometric, ferrographic, and filter analysis. When usedas part of your quality assurance program, oil and wearparticle analysis will detect abnormal wear modes inaviation systems, long before the wear can lead to anyserious damage. WearCheck's analysis will indicate whencomponents are near failure. This gives you time to planmaintenance. Worn components can be replaced at yourlocal facility avoiding rental, and shipping charges. Inflight shutdowns, as a result of failed critical components,are avoided, as WearCheck's analysis pinpoints the wearsignatures of rolling element bearings, gears, splines, andother critical components. WearCheck's filter andferrographic analysis utilizes the morphology of wearparticles to detect specific wear modes. Avoid installationerrors, and rapid failures, when analysis detects cuttingwear from misaligned components. WearCheck's oil andwear particle analysis you will allow you to realize areduction in the cost of equipment maintenance, and anincrease in aircraft availability and reliability.

SSSpectrometric, or SOAP,analysis is the foundation of anymonitoring system. SOAPmeasures concentrations of theshear mixed layer wear particlespresent in the oil. Trendlineanalysis of this data detects subtlechanges to wear modes in thesystem, usually long before anysigni f icant wear to thosecomponents occurs.

SSpectrometric Oil Analysis

CComponents such as rolling elementbearings have unique failure modes.To detect this, Direct ReadingFerrography (DR-Ferr) is used tomonitor the concentrations of smalland large ferrous wear particles in theoil. Sudden increases in largeparticles, or shifts in the normalbaseline, when compared to historicaldata, indicate an abnormal wearmode.

CDirect Reading Ferrography

llllllny indication of abnormal wear,either by DR-Ferr or SOAP analysis,will trigger an Analytical Ferrogram(A-Ferr). A sample of the microscopicwear metals, and contaminantspresent in the oil, are deposited on aslide and examined under a high-powered microscope. By analyzingparticle morphology, A-Ferr indicatesthe mode(s) of wear present in thesystem, and can detect the cause(s) ofabnormal wear modes.
