4.19 USE AND CARE OF FALL ARREST
SYSTEM
The external fall arrest system is designed to provide a
lanyard attach point while allowing the operator to access
areas of an aircraft for inspection and maintenance pur-
poses. Exit/Enter the platform through the gate area only.
The system is designed for use by one person.
DO NOT OPERATE ANY MACHINE FUNCTIONS WHILE OUTSIDE
OF PLATFORM. BE CAREFUL WHEN ENTERING/EXITING THE
PLATFORM AT ELEVATION.
THE EXTERNAL FALL ARREST SYSTEM REQUIRES AN ANNUAL
INSPECTION AND CERTIFICATION. THE ANNUAL INSPECTION
AND CERTIFICATION MUST BE PERFORMED BY A COMPETENT
PERSON.

IF THE FALL ARREST SYSTEM IS USED TO ARREST A FALL OR IS
OTHER WISE DAMAGED, THE ENTIRE SYSTEM MUST BE
REPLACED AND THE PLATFORM FULLY INSPECTED. REFER TO
THE SERVICE MANUAL.
Prior to Use Inspection
Fall arrest systems must be inspected prior to each use.
Replace if there are any signs of wear or damage to any of
the components.
Prior to use inspection should include a visual inspection
of the following items:
Cable: Proper tension, broken strands, corrosion.
Fittings: Loose fittings and fractures, damage to
hanger
Transfastener: Damage, free and proper sliding
Attaching Hardware: Loose, missing, properly
tightened
Inspecting Cable Tension and Slip
Indicator
Cable tension is adjusted by using the Line Tenser. The
Line Tenser is the disc at the end of the cable (shown
below). When proper tension is achieved, the disc will
spin by hand. When less than proper tension is present
the disc will not turn by hand. The cable will stretch nor-
mally over time. In order to tension the cable the turn-
buckle can be tightened. Rotate the turnbuckle until the
proper tension is achieved.
The slip indicator is the short tube crimped beside the end
connection of the cable. If the cable slips from the end
connection a gap will be present between the slip indica-
tor and the end connection. No gap is acceptable. A cable
that is slipped should be taken out of service and the sys-
tem replaced.
Shown below is the slip indicator as it should appear.
