GENERAL
The R44 is a four-place, single main rotor, single engine
helicopter constructed primarily of metal and equipped
with skid-type landing gear.
The primary fuselage structure is welded steel tubing and
riveted aluminum sheet. The tailcone is a monocoque
structure in which aluminum skins carry most primary
loads. Fiberglass and thermoplastics are used in secondary
cabin structure, engine cooling shrouds, and various other
ducts and fairings. The cabin doors are also constructed
of fiberglass and thermoplastics.
Four right-side cowl doors provide access to the main
gearbox, drive system, and engine. A left-side engine
cowl door provides access to the engine oil filler and dip
stick. Additional access to controls and other components
for maintenance is provided by removable panels and
cowlings.
Stainless steel firewalls are located forward of and above
the engine.
The four cabin doors are removable. Refer to Section 8 for
removal and installation procedures.
