Relatives of the victims of a September air crash that killed 154 people in Brazil have filed a lawsuit against two U.S. companies.

The accident occurred on September 29, when a Boeing 737-800 operated by Brazilian airline Gol, clipped a corporate jet operated by ExcelAire Service Incorporated. The Gol plane crashed, killing everyone on board, while the executive jet landed safely.

The families of 10 of those killed in the Gol flight filed suit in New York Monday against ExcelAire, and Honeywell, which made some of the plane's safety equipment.

The lawsuit alleges that the pilots of the ExcelAire jet were flying at the wrong altitude and the jet's transponder was not operating at the time of the accident.
