A second U.S. law firm has filed a lawsuit against the operator of a business jet involved in Brazil’s deadliest air disaster, alleging pilot negligence led to the accident.

The complaint, a copy of which attorneys gave The Associated Press, cites ExcelAire Service Inc. of Ronkonkoma, N.Y., and its New York pilots, Joseph Lepore and Jan Paladino, as well as Honeywell International Inc., saying its “defectively designed” equipment contributed to the crash.
