R  C. 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.

R  D. Operational Check to Ensure Safety Valve Closes at 260 kts 
R  CAUTION : OBEY THESE PRECAUTIONS WHEN YOU DO THE TEST TO PREVENT DAMAGE_______ 
R  TO INSTRUMENTS: 
R  - PRESSURE SET MUST NOT BE MORE THAN 1050 hPa (31 in Hg) OR 
R  LESS THAN 115 hPa (3.39 in Hg) 
R  - CHANGES IN PRESSURE MUST NOT BE MORE THAN 6000 FEET/MINUTE 
R  - DO NOT SUDDENLY OPEN LINES TO AMBIENT AIR WHILE THE PRESSURE 
R  GENERATOR IS CONNECTED. 
R  CAUTION : THE TOTAL PRESSURE IN THE PITOT SYSTEM MUST NEVER BE LESS THAN_______ 
R  THE STATIC PRESSURE. THE DIFFERENCE BETWEEN THE PITOT AND THE 
R  STATIC PRESSURE CIRCUITS MUST NEVER BE MORE THAN 368 hPa (10.86 
R  in Hg).

5.
 Remove the FALSE TARGET from the applicable proximity sensor 21GA(20GA).

 6.
 Make sure that the travel range of the applicable MLG door is clear.

 7.
 Move the applicable ground door-operating handle to the CLOSE position.

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.
The safety-valve 49GA is energized(valve OPEN).
The applicable MLG door closes.
