1 Citation Mustang Throttle Lever Rigging TLA Rigging Guide

2 This guide is designed to assist maintenance and avionics technicians in using the Pratt & Whitney Ground Based Software or GBS to rig the throttle levers on the Cessna Citation Mustang. The GBS system is sometimes referred to as DPHM which stands for Diagnostics, Prognostics and Health Management. In this document it will be referred to as GBS. For further information concerning the purchase or subscription of the GBS equipment see the latest revision of P&WC Service Information Letter S.I.L. PW

3 Caution This document is supplemental information only, and not technical approved data. It does not replace the Cessna Citation Mustang Maintenance Manual or the Pratt & Whitney Canada PW615F-A Line Maintenance Manual.

4 Abbreviations CDMS= Citation Diagnostics Maintenance System (onboard diagnostics) DPHM= Diagnostics, Prognostics and Health Management EEC= Electronic Engine Control FADEC= Full Authority Digital Engine Control GBS= Ground Based Software TLA= Throttle Lever Angle

5 TLA Rigging Notes Ensure that the fuel boost switches are in the off position before moving throttles. On each screen the throttle lever angle will be displayed real time. Move the throttle through the range and record in the chart. In the above example the cruise detent is out of spec by degrees and degrees respectively. A TLA trim of would be a good starting point to change to. Remember that the value you put in changes all the values for a given channel. The maximum value allowed to be inputted is 5 degrees.

6 Turn battery power and avionics power on.

7 When the Splash Screen displays on the MFD, push the softkey on the right as indicated.

8 Ensure that the system is in the AUX page.

19 Rotate the small FMS knob to drop down the menu. Scroll down to Main Engine and R FADEC A Status. Select the enter button on the FMS pad.

20 Note the TLA in degrees at the lower part of the page. Move the throttle through its range and record the values in the rigging chart.

21 Rotate the small FMS knob to drop down the menu. Scroll down to Main Engine and R FADEC B Status. Select the enter button on the FMS pad.

22 Note the TLA in degrees at the lower part of the page. Move the throttle through its range and record the values in the rigging chart.

23 If TLA is out of range then adjust using the GBS kit.

24 GBS kit P/N consists of the following: 1) PWC69317 Download Cable Assembly 2) PWC90191 RS232-USB Adapter and Cable 3) CD containing the drivers for the RS232-USB adapter 4) CD containing the following software: a. GBS Transfer Module b. GBS Diagnostic Module (GBSLite) c. Interactive Engine Technical Manual (IETM)

25 Make sure that the maintenance switch is in the true position before connecting to the aircraft.

26 Connect the cable- pull the carpet up at the back of the drop aisle in the aft cabin.

27 Select desired channel.

28 Make certain that the engine sync switch is off.

29 Connect the cable to the laptop computer through the serial port. If the computer does not have a serial port, then use the adapter to connect to the USB port. The driver from the CD must be installed before using the adapter.

30 Turn battery power on, avionics is not necessary.
