 Amdt 1

 Boundary Layer Fence 10/86

 Applicability: All model F28 with S/Nos 11092, 11093, 11111 to 11234, 11237 and 11238. Requirement:               Action in accordance with Fokker S.B. F28/57-75, Rev. 1.

            Air-leakage through boundary layer fences results in a deterioration of the wing performance. Modified boundary layer fences provide labyrinth-type seals to overcome this problem. Amendment 1 of this Directive references Rev 1 of Fokker SB F28/57-75 which requires additional work.
