75-17-01 BRITISH AIRCRAFT CORPORATION: Amendment 39-2301. Applies to Viscount Model 744, 745D, and 810 Series airplanes, with Modification D.1860 incorporated.

Compliance is required within the next 125 hours time in service after the effective date of this AD, unless already accomplished.

To prevent interference with the movement of the aileron control in-flight, accomplish the following:

(a) Remove the two A25-1C attachment bolts on the false trailing edge member access door adjacent to the gust lock unit lever, if they are presently installed, and replace with rivets, or an FAA-approved equivalent as shown in Figure 1 of BAC Alert Preliminary Technical Leaflet No. 160, Issue 2, dated December 8, 1972, for 810 series airplanes or Figure 1 of BAC Alert Technical Leaflet No. 292, Issue 2, dated December 8, 1972, for 700 series airplanes.

(b) For false trailing edge member access doors not having the two A25-1C attachment bolts adjacent to the gust lock unit lever presently installed, block off the two bolt- holes with rivets, or an FAA-approved equivalent.

This amendment becomes effective September 1, 1975.
