6.18 J250 Wings (J250/J450)
6.18.1 Description
The J250 wing is a semi-cantilever, stressed-skin type with a main spar. The wing is a moulded
structure with a series of ribs that are bonded through the moulding process to the fibreglass skin,
fuel tanks and to the spar.
The forward wing attachment is an extension of the forward sub-spar. The rear attachment is an
extension of the rear sub-spar (also known as the wing attachment lug or fork). Both wing
attachments are contained in a reinforced Wing End Plug and bond to the wing skins. The Wing End
Plug distributes load from the attachments to the main spar. Both attachments are through stainless
steel threaded bushes bonded into the attachment blocks.
The wing internal structure is sealed and only needs to be accessed for repairs.
The J250 family wings are different to the modular wing families discussed above. While major parts
(ailerons, flaps etc) are different, similar principles and procedures are used while the hardware used
– hinges, nuts bolts etc are the same. Figure 59 and Figure 60 refer for the overall assemblies while
details are as shown in Figure 48 & Figure 49.
Note that early example of this wing type used plain flaps - where the flap is similar in cross-section
to the aileron and pivots on simple hinges built directly into the trailing edge of the wing (Figure 59).
Later versions used slotted flaps similar in design to those used on all other Jabiru wings (Figure 60).
