The appeal court in French Polynesia has confirmed jail sentences over the 2007 Air Moorea crash, in which 20 people died.
The Twin Otter fell into the sea shortly after taking off because a steering cable ruptured.
The former manager of Air Moorea, Freddy Chanseau, has been given a three-year prison sentence of which 18 months are suspended.
The airline's former technical director, Jacques Gobin, has also been given a three-year prison sentence of which two years are suspended.
The former head of the government's air safety unit, Andriamanonjisoa Ratzymbasafy, has also been given a three-year prison sentence, of which 18 months are suspended.
One more Air Moorea employee was sentenced while two others were acquitted on appeal.
Chanseau was also fined as was the airline itself.
The case first went to court in 2018 when at the insistence of the victims' families the airline employees and aviation officials were charged with involuntary homicide.
Also in 2018, in a separate decision the court of appeal ruled that $US3.3 million had to be paid in compensation to the families of the victims.
