Quality Assurance through Condition Monitoring

Quality assurance is the primary governing aspect of your business. When safety is paramount to your daily operation a condition monitoring program is an inherent part of your procedures. Oil and wear particle analysis is the most widely accepted method of condition monitoring, in use today, for aviation systems. It is no wonder why most OEMs recommend, or insist, upon some form of oil and wear particle analysis.

Oil and wear particle analysis is a combination of spectrometric, ferrographic, and filter analysis. When used as part of your quality assurance program, oil and wear particle analysis will detect abnormal wear modes in aviation systems, long before the wear can lead to any serious damage. WearCheck's analysis will indicate when components are near failure. This gives you time to plan maintenance. Worn components can be replaced at your local facility avoiding rental, and shipping charges. In flight shutdowns, as a result of failed critical components, are avoided, as WearCheck's analysis pinpoints the wear signatures of rolling element bearings, gears, splines, and other critical components.

WearCheck's filter and ferrographic analysis utilizes the morphology of wear particles to detect specific wear modes. Avoid installation errors, and rapid failures, when analysis detects cutting wear from misaligned components. WearCheck's oil and wear particle analysis will allow you to realize a reduction in the cost of equipment maintenance, and an increase in aircraft availability and reliability.

WearCheck's oil and wear particle analysis is effectively used today for a broad range of aviation systems including jet turbine and turbo props, reciprocating engines, helicopter rotors, gearboxes and transmissions and aircraft hydraulic systems.

Test Test Method DescriptionAVI 1AVI 2AVI 3
ICP Analysis
ASTM D5185
Determines the parts per million (ppm) of all wear metals (Fe, Cr, Ni, Pb, Cu…), contaminants (Si, Na, K….), and additives (Ca, P, Zn, Mg, Mo…).
Viscosity
ASTM D7279
Determine the viscosity of the oil at 40°C (non-engine), or 100°C (engine) to determine if oil is still within specification. High viscosity can indicate oxidation, low viscosity can indicate contamination, improper make-up oil.
Visual Screen
WC Method
A picture of both the oil color/clarity and the bottom of the sample bottle are taken, and any level of contamination, visual oil problems or visible wear debris of the oil is recorded.
Acid Number
ASTM D974
Determines overall acidity (AN) of the oil which is an indication of degradation. Single best test to determine change-out interval. AN for non-engine oil samples. 
Water Content
ASTM D6304
Determines level of moisture or water contamination in the oil. 
Particle Count
ASTM D7647
Determine cleanliness levels of oil to ISO4406:1999. High particle count levels can indicate gross contaminant ingress, wear, filter by-pass or all of these issues. 
Filter Debris Analysis
FDA
Microscopic analysis of the trapped debris from the oil filter. Morphological analysis of the wear particles reveals specific components that are wearing and the cause of the wear.  
Ferrography
ASTM D7690
A detailed morphological analysis of the wear debris particles suspended in the oil. A-Ferr can determine the type of wear process and cause of wear in a lubricated system.  
Submitting Samples to the Laboratory

How to properly prepare your samples for return to the WearCheck laboratory using the new QR-coded sample information forms and poly pack mailer.

How not to Submit Samples to the Laboratory

How not to submit samples to the laboratory","Common issues with samples submitted to the WearCheck laboratory are reviewed. Sample issues cause delays, and slow down the sample layout process. Please ensure that you are completing your sample forms, and properly packing your sample when sending them to the WearCheck laboratory.
