R (c) Seal the drain holes of the pitot probe 9DA1 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 3FP1 to the top (nose-up)
R position. Keep the vane in this position with colored adhesive
R tape.
4. Procedure_________
Subtask 32-31-00-720-059
R A. Operational Check to Ensure Safety Valve Closes at 360 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).
NOTE : For corrective action, do the necessary trouble-shooting____
procedures (Ref. TSM 32 PB 101).
