INTRODUCTION
Section I. GENERAL INFORMATION
1-1. SCOPE.
a. This manual provides operating and Aviation
Intermediate Support Maintenance instructions for
personnel on the Modular Engine Test System, (METS),
Part No. LTCT10465-02. The METS is used to test the
T53L-5, -9, -11 and -13 turboshaft; the T53L-7 and -15
turboprop; the T55L-7 and -11 turboshaft, the T63A5A
and A-700 turboshaft; the T74 turboprop; the T73CPCP-
700 and CP-702 turboshaft, and the T700-GE-700, -701,
and -701C turboshaft gas turbine engines in detail.
b. This manual applies only to the METS engine test
trailer assembly, auxiliary trailer assembly and engine
accessories. Detailed instructions for operation, testing
and maintenance of engines tested by METS are given
in the applicable technical manuals.
1-2. DETERMINING COMPONENT LOCATION.
Figure 1-1 illustrates the set-up of the METS. The
forward end of the engine test trailer is determined by
the location of the engine test deck. The forward end of
the auxiliary trailer is determined by the location of the
water tank. The forward end of the engine test dolly is
determined by the location of the mount ring. Directions
are expressed as viewed from the aft end of each trailer,
the engine dolly and each engine.
1-3. FORMS AND RECORDS.
Maintenance forms, records and reports which are
to be used by maintenance personnel at all maintenance

descriptive sequence progresses from each trailer
assembly to the trailer module and to the modular
systems and individual system components. Included
within each portion of descriptive text are supporting
illustrations. Tables 1-1
and 1-2 depicts and identifies the electrical, pneumatic,
and hydraulic symbology used in the schematic
diagrams.
a. METS System Capability. The modular engine test
system provides the basic interchangeable components
or modules for use in two distinct mission objectives:
