831044-1 – Spectro Engine Oil Contamination Sampling (SOAP) Kit
Available now on the Airparts.aero Marketplace.
The 831044-1 is a professional-grade Spectrometric Oil Analysis Program (SOAP) kit, engineered for the precision collection of engine lubricant samples. In the aerospace industry, oil analysis is a fundamental pillar of Condition-Based Maintenance (CBM).1 By analyzing the microscopic metallic particles suspended in the oil, maintenance teams can identify internal engine wear before it leads to catastrophic component failure. This kit provides all the necessary sterile components to extract a representative sample from a turbine or piston engine, ensuring that the fluid reaches the laboratory without external contamination that could skew the analytical results.
The 831044-1 is designed for use in both military and commercial aviation sectors, following standardized protocols for sampling intervals (e.g., every 25, 50, or 100 flight hours). The data derived from these samples—measured in parts per million (PPM)—allows for the trend monitoring of critical internal components such as main shaft bearings, gearsets, and piston rings. For flight departments, the 831044-1 is an essential tool for maximizing engine Time Between Overhaul (TBO) and ensuring the highest levels of operational safety.
Key Features
Sterile Sampling Vials: High-density polyethylene (HDPE) bottles designed to be chemically inert, preventing the leaching of plasticizers into the oil sample.
Leak-Proof Security: Features specialized double-seal caps or parafilm wraps to ensure the sample remains contained during the extreme pressure changes of air transport.
Contamination Control: Includes medical-grade flexible tubing and extraction tools to reach the center of the oil reservoir, avoiding the "sludge" at the bottom or surface contaminants.
Integrated Documentation: Comes with standardized data cards for recording engine hours, oil brand, time since last change, and specific component serial numbers.
Universal Compatibility: Suitable for all major aerospace lubricants, including MIL-PRF-23699 turbine oils and Ashless Dispersant (AD) piston oils.

Why Is SOAP Analysis Critical?
The laboratory uses an Atomic Emission Spectrometer to "burn" the sample, identifying the unique light wavelengths emitted by different metals. The 831044-1 kit captures the evidence required to identify specific wear modes:
| Metal Found | Potential Component Source |
| Iron (Fe) | Cylinder walls, gears, shafts, or camshafts. |
| Copper (Cu) | Bronze bushings, thrust washers, or oil coolers. |
| Silver (Ag) | Main engine bearings or turbocharger bearings. |
| Chromium (Cr) | Piston rings or chrome-plated cylinders. |
| Aluminum (Al) | Pistons, accessory housings, or cooling fins. |
Why Choose 831044-1?
Accuracy in oil analysis starts at the moment of collection. If a sample is taken in a non-sterile container or contaminated by ambient dust (silicon), the laboratory may issue a false "High Wear" alert, leading to an unnecessary engine teardown. The 831044-1 ensures the sample integrity required for high-stakes decision-making. By maintaining a consistent sampling history using this kit, operators can transition from reactive "break-fix" maintenance to a predictive model, significantly reducing unscheduled downtime and improving the residual value of the aircraft.
Note: The 831044-1 is a diagnostic tool. For the most accurate results, the engine should be at operating temperature before sampling (within 30 minutes of shutdown). Always take the sample from the same location (e.g., the oil tank dipstick tube) to ensure trend consistency. Maintenance personnel should refer to the specific Engine Maintenance Manual (EMM) for the correct SOAP sampling intervals and wear metal limits.
