n. CASE Vent Hose 145GS278-17. (See fig. 1-3.)
(1) The hose is attached to the left end of the unit and is stored with two plastic quick-release
clips on the back of the panel.
(2) The hose is a ¼ in. x 36 in. high pressure hose with flared fittings. It is used to pressurize the
ILCA case cavity during a relief valve test.
o. Transducer Test Adapter 145GS278-20. (See fig. 1-2.)
(1) The adapter is stored in the cover of the electrical unit and is connected to SAS 1 connector by
Test cable 145GS278-5 or -6.
(2) The adapter enables the internal transducer of an ILCA to be turned during adjustment
without interconnecting the wiring to the ILCA WIRE HARNESS.
1-11. Test Set Capabilities.
The test set provides control functions to test thrust ILCA 145H7300-8, the boost actuator and extensi-
ble link sections of spare ILCA 145H7300-16, and spare extensible link 145H7350-8.
Pitch actuator 145H7300-13, roll actuator 145H7300-14, and yaw ac-
tuator 145H7300-15 are tested as spare actuators 145H7300-16.

1-13. Leading Particulars.
a. Each ILCA test unit is contained in a two-piece combination case. Each case is airtight and
b. Each unit includes manually operated relief valves which permit the equalizing of test unit
internal air pressure to atmosphere. The electrical unit has two relief valves, one in the cover and one in
the case. The hydraulic unit has one relief valve in the case.
c. The physical dimensions and weights of the units are as follows:
(1) Electrical unit.
