0075 00TM 1-6625-724-13&P0075 00-22PROCEDURE 2: PERFORM FWDVIB TESTa. Perform task 1, Test Equipment Installation/Checkout, procedures 2 &10.b. Turn on aircraft power.c. Setup the measurement mode on the CADU using the flight plan FWDVIB.d. After the measurement setup parameters have been run, the available Test States are displayed (FWDOIL,H/B#1, H/B#2, and H/B#3).e. Operate aircraft on the ground at 100% NR, flat pitch.f. Select FWDOIL using the arrow keys. Press the DO key twice. This test will measure data from theaccelerometer mounted to the forward transmission oil cooling fan.NOTEIf measurement errors occur, press QUIT on the CADU.Either “partial” or “failed” is displayed. When an erroroccurs, an error code is displayed and the error isidentified. Either correct the cause of the error or, if safeto do so, continue with the sequence tests.g. Repeat measurements for all accelerometers that are installed.h. If all Test States are measured a menu will appear to either finish or continue. Highlight finish and press DO,and then select Main Menu and press DO.i. If all Test States were not measured press QUIT, then highlight Save and Exit and press DO to go to the MainMenu.j. Press F2 to enter DISPLAY mode.k. Select Summary Displays and press DO. Select the appropriate component and press DO to display the syncshaft peak vibration for that component. Press QUIT to return back to the Summary Display Menu and selectother components described above.l. Press QUIT to return back to the Display Mode menu.m. Select One Test State to view spectrum data plots for each accelerometer if desired.n. Remove AVA equipment from the aircraft.o. Inventory AVA kit and adapter kit to ensure all parts are removed from the aircraft.PROCEDURE 3: PERFORM AFTVIB TESTa. Perform task 1, Test Equipment Installation, procedures 2 & 9.b. Turn on aircraft power.c. Setup the measurement mode on the CADU using the flight plan AFTVIB.d. After the measurement setup parameters have been run, the available Test States are displayed (H/B#4,H/B#5, H/B#6, H/B#7, XSHFT1 and XSHFT2).e. Operate aircraft on the ground detent at 100% NR, flat pitch.f. Select the desired Test State using the arrow keys. Press the DO key twice. This test will measure vibrationdata.NOTEIf measurement errors occur, press QUIT on the CADU.Either “partial” or “failed” is displayed. When an erroroccurs, an error code is displayed and the error isidentified. Either correct the cause of the error or, if safeto do so, continue with the sequence tests.g. Repeat measurements for all accelerometers that are installed.h. If all Test States are measured a menu will appear to either finish or continue. Highlight finish and press DO,and then select Main Menu and press DO.
