PART I

GENERAL

The MDHI Litter Kit has been designed to facilitate rapid conversion of the
helicopter to an air ambulance configuration. The Litter Kit provides for trans−
porting one or two litter patients as well as one or two attendants in the cargo
compartment of the helicopter. The kit consists of two litters, folding litter sup−
port structure, attaching hardware, and two special doors. The special doors
incorporate provisions for quick installation of bubble windows which permit
high speed and/or long distance transportation of patients and attendants in
comfort. Also included in the kit is a set of basic shape door window glass pan−
els for quick interchange with the bubble glass panels, for normal operation.
