RIO DE JANEIRO, Brazil (AP):

Air traffic controllers share some of the blame for the midair collision over the Amazon in September that killed 154 people in Brazil's worst air disaster, a spokeswoman for the chief investigator said yesterday.

The pilots of the Embraer Legacy 600 executive jet, who survived the collision with a Gol airlines Boeing 737, as well as the air traffic controllers, will likely be held responsible when the official investigation is concluded in just over a month, said the spokeswoman, Tamares Carvalho.

Carvalho confirmed statements by lead investigator Renato Sayao to local media Sunday. It was the first time Brazilian authorities have said that anyone other than the two U.S. pilots of the executive jet could be held responsible for the Sept. 29 crash.

All those aboard Gol Flight 1907 were killed when it plunged into the Amazon rainforest, while the executive jet landed safely with all seven people aboard unharmed.

Because air traffic controllers are military personnel, federal police can only submit their findings to military justice officials, who would then decide whether to prosecute them, Carvalho said.

The air traffic controllers could face up to 12 years in prison on homicide charges and exposing an aircraft to danger because they failed to divert the Boeing after the Legacy disappeared from their radar, Carvalho said.

Carvalho said she did not know if authorities would pursue criminal charges against the American pilots - Joseph Lepore, 42, of Bay Shore, New York, and Jan Paladino, 34, of Westhampton Beach, New York - who have been formally accused by police with exposing an aircraft to danger.

Shortly after the crash, Lepore and Paladino had their passports seized and were forced to remain in Brazil for 71 days before being allowed to return home on condition they agreed to return to face any charges.
