ESCAPE SLIDE PACKAGE (DOOR-MOUNTED) - ADJUSTMENT/TEST
1. General
A. This procedure provides instructions for a system test of the door-mounted escape slide system at each entry or service door.
2. Equipment and Materials
A. Protective Pad - Ensolite - 1 inch x 48 inches - commercially available.
3. Test Door-Mounted Escape slide
A. Install a protective pad to the external airplane skin panel below the door. Tape the pad to airplane skin to prevent ingestion by the slide aspirator.
CAUTION: PLACE A PROTECTIVE PAD ON THE FUSELAGE SKIN. THE FUSELAGE SKIN COULD BE DAMAGED BY THE AIR CYLINDER IF THE SYSTEM IS TESTED WITHOUT THE PROTECTIVE PAD IN POSITION.
NOTE: We also recommend that you lay carpet on the surface where the slide will fall to protect the slide from abrasions.
B. Close and latch the entry or service door.
WARNING: CLEAR ALL PERSONNEL AND EQUIPMENT FROM THE PATH OF DEPLOYING SLIDE INSIDE AND OUTSIDE OF THE ENTRY/SERVICE DOOR. THE SLIDE INFLATES WITH A GREAT FORCE. SERIOUS INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT COULD OCCUR FROM CONTACT WITH THE SLIDE.
C. Make sure the needle on the pressure gage is within the green band.
D. Make sure the girt bar floor bracket fittings are clear of any obstructions.
E. Remove the girt bar from the retainer hooks on slide cover and install the girt bar into the floor bracket fittings.
F. Open the door in a normal manner. DO NOT HESITATE. Continue pushing the door to fully open.
G. Make sure the slide is opened and inflated to usable condition within 10 seconds after the compartment latch assembly is released.
H. Restore airplane to normal.
