[2] They were returned to service in September 1932 having reinforced wing bracing and engine mounts, and new three-bladed metal propellers.
In 1934, they were relegated to shore duties, but were put aboard the Béarn again in 1936, where they were still in service (albeit now thoroughly obsolete) at the outbreak of the Second World War.
This was fitted with a Gnome et Rhône 9A Jupiter engine and had a revised fuselage with side-by-side seating for a pilot and mechanic and an enclosed cabin for six passengers.
