Installation of the Radome
WARNING:
BECAUSE THE RADOME IS LARGE AND HEAVY, A MINIMUM OF TWO PERSONS (OR SUPPORT EQUIPMENT, SUCH AS A CRANE AND SLINGS) ARE NECESSARY TO MOVE IT. IF YOU MOVE IT WITHOUT THE NECESSARY NUMBER OF PERSONS (OR SUPPORT EQUIPMENT), YOU CAN CAUSE INJURY TO PERSONNEL OR DAMAGE TO THE RADOME.
WARNING:
BECAUSE THE RADOME IS LARGE AND HEAVY, A MINIMUM OF TWO PERSONS (OR SUPPORT EQUIPMENT, SUCH AS A CRANE AND SLINGS) ARE NECESSARY TO MOVE IT. IF YOU MOVE IT WITHOUT THE NECESSARY NUMBER OF PERSONS (OR SUPPORT EQUIPMENT), YOU CAN CAUSE INJURY TO PERSONNEL OR DAMAGE TO THE RADOME.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
WARNING:
BEFORE YOU START WORK, YOU MUST PUT ON A SAFETY HARNESS AND ATTACH IT TO THE ACCESS PLATFORM. WITHOUT A SAFETY HARNESS, YOU CAN FALL. THIS CAN KILL YOU OR CAUSE YOU INJURY.
WARNING:
MAKE SURE THAT:
- THERE ARE NO PERSONS OR OBSTACLES IN THE RADOME AREA.
- THE CAPT AND F/O DISPLAY SELECTOR SWITCHES ON THE WEATHER RADAR CONTROL UNIT ARE SET TO OFF (THIS PREVENTS SYSTEM EMISSIONS ON THE GROUND).
WARNING:
DO NOT OPEN THE RADOME IF THE WIND SPEED IS MORE THAN 25 KNOTS.
CAUTION:
BEFORE YOU INSTALL/REMOVE THE GSE-TOOL, READ THE INSTRUCTIONS IN THE APPLICABLE GSE INSTRUCTION MANUAL. WHILE YOU OPERATE THIS TOOL, CAREFULLY OBEY THEM. IF YOU DO NOT OBEY THE INSTRUCTIONS, DAMAGE TO EQUIPMENT CAN OCCUR.
CAUTION:
TAP THE SURFACE OF THE COMPONENT LIGHTLY. IF YOU APPLY TOO MUCH FORCE, YOU CAN CAUSE DAMAGE TO THE RADOME.
CAUTION:
ONLY USE HAND TOOLS TO REMOVE OR INSTALL OR TORQUE THE RADOME OR SKIRT FASTENERS. IF YOU USE POWER OR IMPACT TOOLS, YOU CAN CAUSE DAMAGE TO THE AIRCRAFT.
CAUTION:
WHEN YOU REMOVE OR INSTALL THE RADOME OR THE ANTENNA, MAKE SURE THAT YOU DO NOT CAUSE DAMAGE TO THE SURFACES THAT ARE PAINTED WITH RADIO-ABSORBENT MATERIAL.
CAUTION:
WHEN YOU INSTALL THE RADOME, MAKE SURE THAT YOU INSTALL THE CORRECT SCREWS/BOLTS (THEY HAVE DIFFERENT LENGTHS) AND TORQUE THEM IN THE CORRECT SEQUENCE. IF THE SCREWS/BOLTS ARE INCORRECTLY INSTALLED, THE RADOME CAN BECOME LOOSE DURING FLIGHT.
1. Reason for the JobNOTE: This procedure is applicable to the S2 GLASS radome (Part Number (P/N) D53132210000).
NOTE: The weight of this equipment is approximately 28kg (62lb).
