: "F-PPPM is the sole B-EC-7 Tout-Terrain (All-Terrain). Alhough at one time it was reported that additional aircraft were under construction, none was completed. Emilien Croses designed and built many Mignet type light aircraft and the B-EC-7 two-seater was built by him together with René Bujon and the designation B-EC-7 stands for Bujon and Emilien Croses design no.7. The unusual tandem wheel undercarriage allowed operations from various surfaces as indicated by the name."
