The second design of Erik T.W. Addyman was the Zephyr. A single-seat sailplane built in 1933 by Addyman.
The Zephyr was of very light conventional wooden construction, with a primary type fuselage with a ply and fabric covered nacelle cockpit.
The undercarriage was a main keel, plus tail bumper. No airbrakes or flaps were fitted. The wings were wire braced.
One only was built, flown by Addyman from many fields in the Lake District and the Pennines before the war. It is believed that the Zephyr was not flown after the war and it remained in storage until Mr Addyman died in 1963. The Zephyr was the acquired by J.C. Riddell but it was found to be suffering from glue failure. It was stored in Riddell’s factory in Hunslet, Leeds.
In September 1970, when it was to have become the property of NAPS as BAPC.39, but it was mysteriously burned before delivery.
