F-AZNS, manufacturer serial number C1-0942, is a British built DHC-1 Chipmunk, mark 20, the military export version.

This prize winning complete restoration has put back in the air a machine with a unique history. The Restoration was made in compliance with French regulations covering historic aircraft. Certificat de Navigabilit d un A ronef de Collection (CNRAC).
Built in October 1953, F-AZNS was taken on charge in February 1954, by the Royal Egyptian Air Force (REAF) of King Farouk and assigned the serial number 1655.
As far as is known, it is the only survivor of the 56 Chipmunks sold to Egypt and the only aeroplane flying today, which served in the REAF.
De Havilland drawings for the REAF order and paint traces on the structure were used to document the restoration to its original colours.
One of only two aircraft, in flying condition in the world, that were present in theatre of action during Suez war of 1956 and the only one flying in Europe.
The airframe bore traces of damage sustained when attacked on the ground during that war. In respect of its historical background, where these traces did not impact flight safety, they were retained.
Probably withdrawn from service before 1958, when Egypt changed their air force markings, it was photographed in a semi derelict state in a mechanics school in Egypt in 1986.
Restored between 1999 and 2018, it first flew again in April 2018.

The restoration spanned 18 years and required 5200 hours of professional quality work. Missing or damaged parts were replaced with new or serviceable components matching the de Havilland parts list. All components with fatigue life limitations were replaced with new parts.
