CAUTION
The Magnetic RPM Sensor must be installed in the
prescribed position or an incorrect blade may be
used as the reference blade. Blade color-coding
must be determined to be correct prior to starting
work on rotor.
CAUTION
Always install lockwire after tightening the jam nut.
A loose jam nut could cause aircraft damage.

1. GENERAL PROCEDURES
This section includes unpacking instructions, installation instructions, self-test procedures, and operating procedures.
2. UNPACKING
The following is a general procedure for unpacking and installing the AVA equipment on the aircraft to be tested. This
procedure should be considered a guideline.
The AVA equipment is contained in two carrying cases. The component case, marked AVA Basic Kit, contains the
Data Acquisition Unit (DAU), Control and Display Unit (CADU), and Universal Tracking Device (UTD). It also contains
the Credit Card Memory (CCM) device and room for several accelerometers and their cables.
The accessory case, marked Adapter Kit, may contain the specific aircraft power cables, the UTD mounting brackets,
a multi-pin connector cable, accelerometer mounting blocks, and various cables for the optical and magnetic RPM
sensors. Each accessory case is aircraft specific and contains the items required for use with that aircraft.
3. INSTALLATION
Refer to WP0002 00 table 1 for a list of items included in the basic kit. WP0002 00 table 2 provides a list of items for
each type of aircraft. WP0002 00 table 3 is a list of available accessories. Figure 1 shows a typical AVA system
interconnect.
a. AIRCRAFT CONFIGURATION.
The aircraft equipment setup configuration will vary widely depending on the type of aircraft and operation
being performed. This paragraph describes basic installation procedures and guidelines common to all
installations. For aircraft specific details, consult the appropriate work package.
The number, type, and position of the required aircraft sensors are dependent upon the aircraft setup script.
For simpler aircraft, generally two accelerometers, a Magnetic RPM Sensor, a UTD, a CADU, and a DAU
must be installed. WP0001 00 figure 1 shows a typical system setup of an aircraft installation.
