DD Form 2026: Oil Analysis Request

Enter the designated Oil Analysis Program (OAP) laboratory, which will perform the sample analysis. Contact your respective Service Oil Analysis Program Management Office for a list of available laboratories.

Enter the designation of the operating activity submitting the sample.

Enter complete address information for the operating activity. This is optional for Ships and USAF activities.

Enter the six-character unit identification code (Ex: N00421).

Enter the name and rank of the person submitting the sample.

Enter the phone number and email address of the person submitting the sample.

Enter the name and email address of the Maintenance Supervisor responsible for the submitted sample. For Navy, enter information for the Maintenance Material Control Officer (MMCO) or other responsible individual.

Check the appropriate block for the source of the sample.

Enter the designation or description of the component or equipment being sampled. For engines, include the type, model, and series.

Enter complete serial number of the component or equipment being sampled.

If applicable, enter position or position number of the component. This is common for engines and some gearboxes.

Enter mission, design and series (type, model, series) of end item which contains the component or system being sampled. This is often an aircraft or vehicle.

Enter the complete end item serial number (aircraft bureau number).

Enter the date in the format day/month/year on which the sample was taken, e.g., 03DEC2023 for December 3, 2023.

Enter local time sample was taken using 24 hour clock, e.g., 0700, 1600, 2200, etc.

Enter local time the engine was shutdown prior to oil sampling using the 24-hour clock.

Enter the total hours/miles since new of the component being sampled to the nearest whole hour/mile (round up at 0.5). Indicate if the number reported is in hours or miles.

Enter the total hours/miles since overhaul of the component being sampled to the nearest whole hour/mile (round up at 0.5). If the equipment has never been overhauled, the total operating hours/miles since new are reported.

Air Force personnel will normally enter total flying hours.

For Navy ship equipment enter hours if known, otherwise leave blank.

Enter hours/miles since oil change on the component being sampled to the nearest whole hour/mile (round up at 0.5).

If available, enter the miles or hours of the aircraft or vehicle upon which the component is installed. This is equivalent to the odometer reading. Specify if hours or miles are reported.

Enter reason for taking sample. Mark applicable block; if "Other" block is marked, specify reason for sample, e.g., initial sample, warning light, etc. NOTE Oil consumption information is essential to the evaluation process for trend analysis and to determine if a system is using excessive amounts of oil.

If the sample is a special sample, it must be prominently marked in red (such as red borders), both on the form and on the outside of the mailing container to alert the laboratory to the need for immediate processing.

Report suspected excessive oil usage to both the local system manager(s) and the local oil analysis laboratory.

Enter the quantity of oil added since the last sample and specify the measurement used.

Mark the appropriate block. See Volume 1, Work Package 003 of the JOAP Manual for definitions of Tube, Drain, or Valve sampling.

Mark the appropriate block.

For Oil Type, enter the specification number, product designation or product name.

In Remarks, enter any pertinent sample information.

On initial samples of new equipment, provide the JOAP laboratory with the following: (1). System oil capacity. (2). Sampling / Oil change interval. (3). Minor maintenance actions within the oil system.

If visual inspection of MCD is required, Air Force or Army customers are to check the appropriate block for the debris observed on the chip detector, i.e. "WITHIN LIMITS", "EXCEEDS LIMITS". If not required, the submitter should mark "UNKNOWN/NA".

Submitting activities may use this space to assign a designation to the sample being submitted thus facilitating the submission of multiple samples and oil analysis requests in one shipping envelope or container.

The For Laboratory Use Only section of the form is completed by the laboratory personnel performing the analysis of the oil sample. It is rarely used since most oil analyses are automated and use computer systems to record results and provide results back to customers.

Check the appropriate block for the elemental / wear metal instrument used, i.e. "SPECTROMETER" or "FL-58". Fill in all values obtained for each element as indicated by the instrument.

Fill in the results for the tests performed.

Fill in the results along with the Overall Class and/or Overall ISO Code, if performed.

Enter the appropriate recommendation code based upon the oil analysis test results.

Provide any additional information appropriate based on the results obtained.

Reporting Chip Detector Inspection Results.

Documenting / Reporting Analysis Results when automated reporting systems are not available.

The Transient Aircraft Oil Analysis Record section of the form is on the back side. It is used in the uncommon situation where the oil analysis servicing of a specific component is being transitioned from one oil analysis laboratory to another and the losing laboratory is not equipped with an automated data system.
