59-10-10 VICKERS: Applies to All Viscount Model 745D Aircraft.
Compliance required as soon as possible but not later than July 1, 1959.
A case has occurred of the failure of flap telescopic tie rod end, Vickers P/N 70103-3139. The investigation revealed that the depth of the drilling for the internal thread had been extended beyond the normal drawing dimension of 0.95 inch which resulted in a reduction in wall thickness and strength across the shoulder.
Inspect flap telescopic tie rod ends, Vickers P/N 70103-3139, assembled on No. 3 and 4 flap telescopic tie rods. If the depth of the internal threads exceeds 0.95 inch measured from the end face of the tie rod end, the part must be replaced. The above inspection must also be made on all stocks of parts prior to installation on an aircraft.
(Vickers-Armstrongs PTL 207 covers this subject.)
