1996 brought the biggest changes to date. No.1 Tactical Aviation Support Squadron, an air maintenance unit co-located in St-Hubert, was absorbed by 438 Squadron, as was 401 Squadron which had been the CH-136 Kiowa Operational Training Unit. Although only officially disbanded on 1 January 1998, 401 Squadron only remained active on paper. With 401 Squadron came the Field Tactical Training Flight, formerly the 3 Field Tactical Training Unit moved to St-Hubert from CFB Bagotville the year before. This technical school currently located within the Ecole Nationale d'Aerotechnique also located on the St-Hubert airfield, offers all Griffon related technical training for technicians, maintenance managers, and flight engineers.
