2.1. WING
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 lead-
ing edge is attached to the front spar whereas the flap (“slotted”) and the aileron (“frise”) 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 120
litres each (31,7 gallons).
The ailerons and flaps are made by an aluminium spar attached to a formed sheet metal
leading edge and metal ribs; an aluminium skin surrounds the aileron structure.
