6.14 J160 Wings (J160)
6.14.1 Description
The J160 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.
For details of wing assemblies, refer to Figure 48 & Figure 49 for earlier aircraft and Figure 50, Figure
51 & Figure 52 for later variants.
