In case of propeller/tail proximity, a blade break can hit the tail or produce destructive vibrations, leading to a loss of control.<ref>[[Grinvalds Orion]] crash in 1985, Experimental magazine n°2, March 1986, pages 20-24, Extrait du Rapport d'expertise: "La cause initiale de l'accident la plus probable est la rupture du mécanisme de commande de pas d'une pale de l'hélice. Cette rupture a a engendré des vibrations importantes de la partie arrière de l'avion... ruptures structurales... privant les pilotes des commandes de vol de profondeur et de direction". Failure of the pitch command system of one blade, important propeller vibrations, structural break, loss of pitch and yaw control</ref>
