1.3.2 Wings
The wings are of the rectangular type with rounded wing tips. The airfoil is a modified 4412. The
structure is made up of two tubular spars in aeronautical aluminium alloy (doubled on the inside
where necessary) and a classically designed system of compressors and diagonals. Each wing
consists of 10 bays and a wing tip and 11 ribs attached to the tubular structure. Each wing root
contains a welded aluminium tank containing 9 gallons of fuel (or more with extender fuel tank
option). The in-tank fuel gauge is visible to both pilots from inside the cockpit. The wing is
covered with 3.6oz Dacron fabric, which is sewed to the ribs on both the upper and the lower wing
surface.
Wing struts and jury struts are of extruded aviation grade alloy.
There are some easily removable round inspection panels kept in place by a spring allowing
inspection of the wing attachment connections and optional strobe lights.
The flaps can be set to 3 different positions with a maximum extension of 35 degrees. The
employed alloys are of the 2024-6061/T6 type. All nuts and bolts are of aircraft quality (AN).
All
the engineering documentation concerning load tests and studies was completed with the aid of
sophisticated software such as the French Catia (Dassault) and Nastran.
NOTE:
no major repair or alteration, as outlined in ASTM 2483, are authorised at this time. For
eventually obtaining engineering approval for any major repair or alteration, contact Zlin Aviation.
