Woman Suing Bell Helicopter

A woman whose son was killed when his helicopter went down in the Gulf of Mexico is suing Bell Helicopter.

The lawsuit also includes transportation company Rotorcraft Leasing, L.L.C.

Her son was among five men who died in December when their air taxi helicopter crashed into the gulf on its way to an oil platform.

The lawsuit alleges Bell Helicopter is at fault for designing the aircraft to be "susceptible to engine failure caused by ingestion of snow and ice."
