Redoine Faid, who had multiple convictions for armed robbery, was sprung from the jail in Reau, 50 kilometres (30 miles) southeast of Paris, in 2018.
The 51-year-old, who was arrested after three months on the run, went on trial last month.
The Assize Court in the capital was packed with more than 100 members of the public.
The 14-year sentence handed down by the judge was lighter than the 22 years that prosecutors had requested.
As his previous sentences for robbery and jailbreak were due to run to 2046, he could now be in prison until 2060.
Rachid Faid, who took a helicopter pilot hostage and forced him to land in front of the visiting rooms of Reau prison, got 10 years.
A third brother, 63-year-old Brahim, who was inside the visiting rooms with Redoine at the time, swore during the seven-week trial that he had not known of the plan.
