In \cite{PK}, the authors constructed a translation plane Π of order 112 arising from replacement of a sporadic chain F′ of reguli in a regular spread F of PG(3,11). They also showed that two more non isomorphic translation planes, called Π1 and Π13, arise respectively by derivation and double derivation in F∖F′ which correspond to a further replacement of a regulus with its opposite regulus and a pair of reguli with their opposite reguli, respectively. In \cite{AL}, the authors proved that the translation complement of Π contains a subgroup isomorphic to \SL(2,5). Here, the full collineation group of each of the planes Π, Π1 and Π13 is determined
