New York ( CNN ) -- The attorney for a family who filed a wrongful death lawsuit in the death of Mark Bavis , 31 -- who died in the September 11 , 2001 , terrorist attacks -- says new court documents offer a glimpse into airport security lapses that made the attacks possible . Security screeners at Boston 's Logan International Airport allegedly had trouble communicating in English , were unable to detect weapons -- such as a chemical spray called Mace -- and were operating under a general manager who was unaware of the al-Qaeda terrorist threat . `` What it came down to that day was that entities did not do their job , '' said Mary Schiavo , attorney for the Bavis family . Mark Bavis , a hockey scout aboard United Airlines Flight 175 , died when his flight crashed into the World Trade Center 's south tower . `` This suit is not about money , it never has been , '' Schiavo added . `` It 's about accountability . '' Thousands of families received monetary compensation following legal settlements involving 9/11 victims . The documents were filed in Manhattan federal court in a lawsuit against United Airlines , a private security company and Massachusetts Port Authority -- which owns and operates Logan airport . The defendants say they are not liable for the attacks . Massport spokesman Matthew Brelis declined to comment on the case , but his agency in May filed a motion to dismiss , saying `` Mr. Bavis 's tragic death was not due to the breach of any security layer for which Massport had authority or responsibility under federal law . '' In the filing , Massport claims the Federal Aviation Administration regulations for screening passengers and their baggage was not the responsibility of airports but the airlines . A spokesman for United Airlines declined comment . Schiavo maintains that the airline `` had exclusive control over its aircraft and over security procedures '' and are ultimately responsible for the safety of its passengers . The trial date is set for November 7 .
Court records provide evidence of misconduct in 9/11 lawsuit , attorney said . Defendants say the breach was not their fault . Mark Bavis died when his plane crashed into the World Trade Center 's south tower .
