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
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
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
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.
