PART I
INTRODUCTION
The MDHI Hoist Kit is a fixed position, electrically operated unit. The hoist
assembly is designed for rapid installation and removal to facilitate maximum
utility of the helicopter. Approximately 110 feet of cable is provided with limit
switches incorporated to automatically stop the hoist at either extreme. The
rate of travel of the cable is approximately 60 feet per minute. The pilot is
provided with a recessed cable cutter button on the cyclic stick. The hoist oper−
ator is provided with a safety harness, a three position switch to raise or lower
the cable, and a guarded cable cutter button. The cable cutter is a redundant
circuit, electrically initiated, pyrotechnic device. A door ‘‘hold−open’ ’ is provided
for use during hoisting operation.
When the kit is installed, an owner or operator holding a valid Rotorcraft Ex−
ternal Load Operator Certificate may utilize the helicopter for hoisting opera−
tions, compensation for hire, when operated by a qualified pilot. OPERATIONS
WITH A LOAD ON THE HOIST SHALL BE CONDUCTED IN ACCORDANCE
WITH APPLICABLE PORTIONS OF FEDERAL AVIATION REGULATIONS
PART 133. The operator may obtain a multiple airworthiness certificate under
provisions of FAR 21.187.
