d. Designate a unit point of contact to monitor activity compliance with oil analysis requirements and to

establish close liaison with the supporting oil analysis laboratory for all matters relating to activity support and

equipment condition.

e. In accordance with OPNAVINST 4790.2 Series, U.S. Navy customers (aircraft reporting custodians)

operating aircraft are additionally responsible for maintaining records of oil analysis results to highlight equipment

trends. Although the laboratory operator/evaluators are responsible for evaluating analysis results and providing

recommendations to the customers, the customer has the ultimate responsibility to determine what action, if any,

is required in response to a laboratory recommendation. In order to fulfill this responsibility, certain equipment oil

analysis and maintenance information must be available to the maintenance manager. The content and format of

the oil analysis trend record may vary between activities but the basic information to establish a trend record must

be maintained by all aircraft reporting custodians. Figures 3-1 and 3-2 illustrate formats considered adequate for

Oil Analysis Trend Forms and may be adapted for use by operating activities. Oil Analysis Trend Records are not

available as standard forms and must be produced by individual user activities. Oil Analysis Trend Forms shall be

maintained for each item of organizational equipment entered in the oil analysis program. Trend records shall

remain on file until the equipment undergoes overhaul/first degree repair, at which time a new base line/trend will

be established for the equipment.

3-3. Laboratory Support of Customers. The JOAP laboratory listed in Appendix B closest to their area of

operation or capable of providing the most responsive support will normally support operational activities.

Activities experiencing any problems with laboratory support or anticipating changing supporting laboratories due

to change of operating site should request guidance via the normal chain of command. The Major/Type

Command, the laboratory's parent command and the appropriate service oil analysis Program Management office

will coordinate assignment or transfers of customers between laboratories. Interservice laboratory support

workload matters should be coordinated through the appropriate service chain of command directly to the service

Program Management office. Customers desiring to obtain oil analysis support from an oil analysis laboratory not

currently approved and qualified within the Joint Oil Analysis Program must submit a request through the chain of

command to the appropriate service Program Manager. The following information will be provided:

Laboratory name/location and affiliation

Type spectrometer

Type standards

Laboratory operator qualifications

Description of support work to be performed

Details of proposed support agreement

Service Program Managers may approve such laboratories if they qualify for entry in the JOAP

Correlation Program in accordance with paragraph 4-3. Laboratories may be approved for interim

operational support by the appropriate service Program Manager(s) following successful completion of

analysis of three special sets (six pairs) of correlation samples as specified in paragraph 4-3.e.

Laboratories shall then be entered in the JOAP Correlation Program and receive final Program Manager

approval or disapproval based on Correlation Program performance results.

Sampling Intervals. Sampling intervals have been established for specific equipment based upon

3-4.

engineering design, average wear rates, projected failure points, and the hazards related to potential

system/equipment failures. Therefore, equipment sampling should be closely monitored for compliance with

established intervals. The sampling interval should not vary more than plus or minus 10 percent of that specified

for each Type/Model/Series of equipment except as modified by appropriate equipment managers.
