Not sure about the S.E.P.1 I know that the Smiths S.E.P 2 was fitted to the Vickers Viscount. As following the accident of Viscount 803 Aircraft EI-AOM near Tuskar Rock, Co. Wexford on 24th March, 1968 an examination of components of the autopilot – a Smiths S.E.P.2 was done at Dublin Airport on 21st October, 1968.
