ING
Each wing is connected to the fuselage by means of two bolt attachments and a
single strut brace per side. The wings are made up of a central light alloy torsion
box; a light alloy leading edge is attached to the front spar whereas the flap
(“slotted”) and the aileron are attached to a rear spar through two hinges each.
The torsion box consists of a front and rear spar that represent its front and rear
vertical walls; a series of ribs and wrap-around panels complete the structure. Front
and rear spars are integrated with wing-fuselage attachment fittings.
Integral fuel tanks are located in the wing box, behind the main spar, with a capacity
of 70 litres each (18.5 gallons).
The ailerons and flaps are made by an aluminium spar attached to a formed sheet
composite material leading edge and metal ribs; an aluminium skin surrounds the
aileron structure
