R to OFF.
The Air Data Inertial Reference Unit 1(ADIRU 1) energizes.
The handle will not move.
NOTE : There can be unwanted movement
____ of the ground door-operating handle because of remaining green hydraulic pressure. If the handle can be moved more than five times, it is possible that the safety valve 49GA is defective.

R H. Removal of the Test Equipment
R (1) Disconnect and remove the ADAPTER COVER-STATIC PORT equipment from
R the static probes 7DA1 and 8DA1.
R (2) Disconnect and remove the ADAPTOR-CHARGING,PITOT PROBE from the pitot
R probe 9DA1.

R J. Installation of the Test Equipment
R (1) Connect the GROUND PRESSURE GENERATOR to the static and pitot probes
R as follows:
R (a) Connect the ADAPTER COVER-STATIC PORT equipment to the static
R probes 7DA2 and 8DA2
R (b) Connect the ADAPTOR-CHARGING,PITOT PROBE to the pitot probe 9DA2.
R (c) Seal the drain holes of the pitot probe 9DA2 with colored
R adhesive tape.
R CAUTION : WHEN YOU SEAL THE DRAIN HOLE IN THE PITOT PROBE, DO NOT_______
R SEAL THE HOLE DIRECTLY WITH THE COLORED ADHESIVE TAPE.
R ALWAYS PUT A PIECE OF PLASTIC ON THE HOLE AND USE THE
R TAPE TO ATTACH THE PLASTIC.
R IF YOU SEAL THE DRAIN HOLE DIRECTLY WITH THE ADHESIVE
R TAPE, THERE IS A RISK THAT SOME OF THE ADHESIVE WILL
R STAY ON THE HOLE AND COLLECT PARTICLES. THIS CAN
R SUBSEQUENTLY CAUSE BLOCKAGE OF THE HOLE AND THUS
R INCORRECT OPERATION OF THE PROBE.
R (d) Move the vane of the AOA sensor 3FP2 to the top (nose-up)
R position. Keep the vane in this position with colored adhesive
R tape.
