The defence in French Polynesia's trial over the 2007 Air Moorea crash has called for all suspects to to cleared.
Twenty people died when the Twin Otter fell into the sea shortly after taking off from Moorea for Tahiti.
The defence lawyers spoke shortly before the trial ended, with a verdict expected on January 22nd.
The prosecution wants four people, including the head of French Polynesia's civil aviation, to be given jail sentences on charges of involuntary homicide.
It also wants each of them to be fined $US24,000 and the airline to be fined $US240,000.
The crash investigation showed steering cables tore in several places in the front section of the aircraft, but the defence has challenged the findings.
A month ago French Polynesia's court of appeal ruled that $US3.3 million had to be paid in compensation to the families of the victims.
