AFI21-131 JOINT OIL ANALYSIS PROGRAM
MilReg AFI21-131 Frequently Asked Questions

What is AFI21-131 JOINT OIL ANALYSIS PROGRAM?
AFI21-131 is the Air Force regulation that establishes guidelines and procedures for the Joint Oil Analysis Program (JOAP), which is used to monitor the condition of lubricating oils and hydraulic fluids in Air Force equipment.

What is the purpose of the JOINT OIL ANALYSIS PROGRAM?
The primary purpose of the JOAP is to detect abnormal wear, contamination, and other fluid-related problems within Air Force equipment by analyzing oil samples on a regular basis.

Who is responsible for implementing and maintaining the JOINT OIL ANALYSIS PROGRAM?
The Air Force Materiel Command (AFMC) is responsible for implementing and maintaining the JOAP, including providing technical expertise, laboratory analysis, and training to support the program.

How often should oil samples be taken for analysis under the JOINT OIL ANALYSIS PROGRAM?
As a general guideline, oil samples should be taken at regular maintenance intervals as specified in the applicable technical publication or equipment-specific maintenance requirements. The frequency may vary depending on equipment type and operating conditions.

How should oil samples be collected for analysis under the JOINT OIL ANALYSIS PROGRAM?
The collection of oil samples should follow the procedures outlined in the applicable technical publication or equipment-specific maintenance requirements. Special care should be taken to avoid contamination and ensure representative samples are obtained.

What happens to oil samples once they are collected under the JOINT OIL ANALYSIS PROGRAM?
Oil samples are sent to an accredited laboratory for analysis. The laboratory performs a variety of tests to assess oil condition, detect contaminants, and identify abnormal wear metals.

How are oil analysis results communicated to unit personnel under the JOINT OIL ANALYSIS PROGRAM?
The laboratory generates a comprehensive report for each oil sample, detailing the test results and providing recommendations based on the findings. These reports are then distributed to the appropriate unit personnel for review and action.

What actions should be taken based on the JOINT OIL ANALYSIS PROGRAM results?
Based on the analysis results, unit personnel should take appropriate maintenance actions, such as changing the oil, cleaning filters, or addressing specific equipment issues identified in the report. These actions should be guided by the recommendations provided in the analysis report.

Is there any specialized training available for personnel involved in the JOINT OIL ANALYSIS PROGRAM?
Yes, the Air Force Materiel Command provides training courses to personnel involved in the JOAP. These courses cover sample collection, handling, interpretation of analysis results, and proper maintenance actions based on those results.
