A. Get Access

WARNING: DO NOT OPEN THE PASSENGER/CREW DOOR IF THE WIND SPEED IS MORE THAN 65 KNOTS.

WARNING: BEFORE YOU START WORK ON THE DOOR, MAKE SURE THAT:

THE EMERGENCY CONTROL HANDLE IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED.
THE PERCUSSION LEVER OF THE DOOR-DAMPER AND EMERGENCY-OPERATION CYLINDER IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED.

IF YOU DO NOT OBEY THESE INSTRUCTIONS, THE DOOR CAN OPEN WITH FORCE OR THE ESCAPE SLIDE CAN DEPLOY SUDDENLY. THIS CAN CAUSE INJURY AND/OR DAMAGE.

WARNING: STOP THE OPENING PROCEDURE IF THE RED WARNING LIGHT FLASHES. IF THE RED WARNING LIGHT FLASHES, REMAINING PRESSURE CAN CAUSE THE DOOR TO OPEN SUDDENLY AND CAN:

KILL OR CAUSE SERIOUS INJURY TO PERSONS
CAUSE DAMAGE TO THE AIRCRAFT.

(1) Put the ACCESS PLATFORM 5M (16 FT)- ADJUSTABLE in position in front of passenger/crew door 832 or 842.
(2) Open passenger/crew door 832 842 (Ref. AMM TASK 52-10-00-010-001).
(3) Obey the special precautions before you start work on the applicable door (Ref. AMM TASK 52-10-00-860-001).

Subtask 52-13-14-210-051-A ** ON A/C NOT FOR ALL

A. Inspection of the Door Damper and Emergency Operation Cylinder.

Bottle of the Damper and Emergency Operation Cylinder of the Aft Door ** ON A/C NOT FOR ALL

(1) Make sure that the door is open.
(2) Do a visual inspection of the door damper and emergency operation cylinder. Make sure that there are no fluid leakage, corrosion, cracks, marks or dents and that the components are correctly attached.
(3) Do a visual inspection of the paint. Make sure that the paint is not flaked or peeled.
(4) Do a check of the pressure.

CAUTION: THE PRESSURE ON THE PRESSURE INDICATOR OF THE BOTTLE MUST BE RELATED TO THE PRESSURE CORRECTED FOR TEMPERATURE.

(a) Write the pressure value shown on the pressure gauge (1).
(b) Compare this value with the value shown on the placard (2) for the ambient temperature.

NOTE: The minimum operating pressure value for the door to be serviceable is 1305 PSI at 20°C.

NOTE: To get a correct pressure value, let the air bottle become stable at ambient temperature before you do the inspection.

NOTE: Bubbles in the pressure gauge with a maximum diameter equal to the dial are permitted.

(c) If the oil level, in the pressure gauge, is not sufficient to have the pointer in the liquid (with the dial horizontal), you must discard the pressure gauge.
(d) If the pressure is not correct, pressurize the cylinder bottle (Ref. AMM TASK 52-10-00-614-001).
