D.  Control Cabin Equipment
WARNING:  FAILURE TO REMOVE COVERS FROM PITOT PORTS BEFORE FLIGHT MAY CAUSE LARGE ERRORS IN AIRSPEED-SENSING AND ALTITUDE SENSING SIGNALS, WHICH MAY LEAD TO LOSS OF SAFE FLIGHT.
CAUTION:  REMOVE ALL COVERS. ENGINES SHOULD NOT BE OPERATED WITH COVERINGS IN PLACE BECAUSE THE COVERINGS CAN COME OFF AND DAMAGE THE ENGINES.
(1)  
Remove the pitot covers.

(2)  
Remove the covers from the vertical stabilizer pitot tubes.

(3)  
Remove the “PITOT PROBES COVERED” tag from the left control wheel in the flight deck.

(4)  
Remove the tape or covers from these components:

(a)  
The temperature probe

(b)  
The angle of attack sensor

(c)  
The ice detector

(d)  
The static pressure sources

WARNING:  FAILURE TO REMOVE BARRICADE TAPE AND VINYL ADHESIVE TAPE FROM THE STATIC PORTS BEFORE FLIGHT MAY CAUSE LARGE ERRORS IN AIRSPEED-SENSING AND ALTITUDE SENSING SIGNALS, WHICH MAY LEAD TO LOSS OF SAFE FLIGHT.
CAUTION:  REMOVE ALL BARRICADE TAPE AND VINYL ADHESIVE TAPE. ENGINES SHOULD NOT BE OPERATED WITH COVERINGS IN PLACE BECAUSE THE COVERINGS CAN COME OFF AND DAMAGE THE ENGINES.
(5)  
Remove all barricade tape and vinyl adhesive tape from the static ports.

(a)  Inspect each static port and if necessary use naphtha or equivalent to remove all tape residue, dirt and other contaminants around the port.

(6)  
Remove the “STATIC PORTS COVERED” tag from the left control wheel in the flight deck.

(7)  
Install the quick-opening drain valve assembly and the drain plug to the pitot and static drain tubes (Ref 34-11-01) if they were removed.

(8)  
Do a check of the portable fire extinguishers:

(9)  
Weigh the fire extinguishers.

(10)
If the weight is less than the quantity shown on the nameplate, remove the fire extinguisher and recharge or replace it.

(11)
Install the windshield wipers, if they are not installed.

(12)
Install the rain repellent bottle (Ref 30-43-0).

(13)
Make sure all the control cabin equipment installations are completed.

(14)
Do a test of the operation of the pitot-static system (Ref 34-11-01).

(15)
Do a test of the operation of the rain repellent system (Ref 30-43-0).

(16)
Do a test of the operation of the windshield wipers (Ref 30-42-0).

(17)
Drain all the pitot and static lines.

(18)
Visually examine the pitot heads and the static ports for damage of contamination.

(19)
Do an operational check of the pitot-static system instruments (Ref 34-11-01).
