The hosting boom assembly should NEVER be lifted to the raised position by means of winching the
boom with another vehicle. Boom could free-fall resulting in possible death or injury to personnel.
In the event of a power loss to both main engine and auxiliary power unit (APU), the hoisting boom assembly has no
RAISE/STOW capabilities. If the boom is in the STOWED position, it is impossible to perform engine deck maintenance.
It should be stressed that removal of the hoisting boom assembly takes about two hours and requires a crane for lifting off, but re-
moval is the best method for performing maintenance from a safety aspect.
Should operation of the boom be considered necessary, the following emergency operation procedure could be
applied using an M88A1 Recovery Vehicle as the slaving vehicle.
