The airworthiness directive

56-26-04 VICKERS-ARMSTRONG: Applies to All Viscount Model 745D Aircraft.

Compliance required as indicated.

Service experience has indicated that cracks may develop in certain pre-Modification D.1031 engine nacelle attachment brackets. Accordingly, Vickers-Armstrong (Aircraft) Ltd. issued Preliminary Technical Leaflet No. 111, Issue 1, dated October 19, 1956, covering this subject. The British Air Registration Board considers the inspections recommended therein mandatory, in which the FAA concurs. When brackets to Mod. D.1031 are installed, the special inspections detailed in PTL No. 111 do not apply.

This supersedes AD 55-22-05.
