Dewoitine D 570

At the end of March 1933, criticism of the gulled wing of the D 560 led Emile Dewoitine to replace this with a wing of classic parasol form and of marginally reduced span and area. Re-designated D 570, the modified prototype entered flight test on 27 November 1933, transferring from Francazal to the Centre d'Essais at Villacoublay early in December. It flew back to Francazal for minor modifications, and, on 21 December, while returning to Villacoublay, suffered an aileron failure and was destroyed.
