58-10-08 VICKERS: Applies to All Viscount 700 Series Aircraft Equipped With 14-Inch Stroke Landing Gear Oleos.
Compliance required by July 31, 1958.
Failures have occurred in the main chassis retraction jack bolts, Vickers P/N 74450-341, which are located in the inner nacelle, port and starboard, due to overtightening of the nut, Vickers P/N 74450-85.
In order to preclude these failures, a nut of improved design, Vickers P/N 74450-423 must be installed to replace the old nut, Vickers P/N 74450-85. The British Air Registration Board considers this mandatory.
The FAA concurs with this action and considers compliance therewith mandatory.
