Pilatus PC-8D Twin Porter

The Pilatus PC-8D Twin Porter was a Swiss ten-seat light transport built by Pilatus Aircraft. The type did not go into production and only one was built.

Work on the Twin Porter started in 1966, it was a modified Pilatus PC-6 high-wing monoplane with the nose-mounted engine removed and two 290 hp Lycoming IO-540-GIB engines mounted on the wing leading edges. The prototype first flew on 28 November 1967. Only one aircraft was built as flight testing was halted in 1969.
