Leutnant Franz Piechulek was a German World War I flying ace credited with 14 aerial victories.
He was assigned to Kampfeinsitzerstaffel 5 on 27 October 1917.[1] He scored his first aerial victory there, downing a Nieuport on 22 November.[2] He then moved on to Royal Prussian Jagdstaffel 41 on 14 December.[1] On 5 January 1918, he set an enemy observation balloon afire for his second win.[2] Four days later, he moved to Royal Prussian Jagdstaffel 56 to pilot an Albatros D.Va or a Fokker D.VII.[1] He arrived the same day as his new Staffelführer, Franz Schleiff.[3] Between 5 March and 4 October 1918, Piechulek rolled up another dozen triumphs,[1] outlasting both Schlieff and his replacement, Dieter Collin.[4]
