 An investigative commission concluded on 4 May 1932 that even the improved M.F.9c model was not usable for training purposes and recommended that the type should be discarded entirely.Director Høver strongly opposed this view, but did not win through with his view that further improvements could save the aircraft and the type was retired and put in reserve on 17 July 1932.The document sent by the Ministry of Defence to the RNNAS was signed by the Agrarian Party Minister of Defence, Vidkun Quisling.
