( CNN ) -- A group of passengers who were aboard a March 27 JetBlue flight out of JFK Airport that was diverted because of erratic behavior by its pilot have filed suit against the airline and pilot . The lawsuit , obtained by CNN , was filed Wednesday in New York State Supreme Court in Queens . It lists 10 plaintiffs and accuses JetBlue of being grossly negligent for allowing Capt . Clayton Osbon to fly , claiming the airline knew or should have known that he was unfit to fly an aircraft at the time of the flight . The lawsuit alleges that Osbon caused significant distress to the passengers , specifically by yelling obscenities and things such as `` Say your prayers , '' `` We 're all going down , '' `` I 'm going to show you Iraq and Iran right now '' and `` There 's a bomb on board . '' JetBlue Airlines does not offer comment on pending legal matters . Sharon Jones , spokesperson for the airline , did say that JetBlue was aware of the claim that was filed , but has not reviewed the complaint . On April 4 , Osbon was ordered by U.S. District Judge Mary Lou Robinson to undergo a psychiatric evaluation . He is scheduled to attend a mental competency hearing Friday morning at the U.S. District Court in Amarillo , Texas , where the flight was eventually diverted . According to court documents filed April 18 by his attorney , Dean Roper , Osbon plans on using an insanity defense . Roper did not immediately return a call for comment . The co-pilot of the flight became concerned about Osbon 's bizarre behavior early in the trip from New York to Las Vegas , according to an FBI affidavit issued shortly after the flight . As the Airbus A320 was climbing out of New York 's John F. Kennedy International Airport , Osbon talked about his church and needing to `` focus , '' the affidavit says . He then told the co-pilot to take the controls and to work the radio , and began talking about religion , making statements that were incoherent , it says . The concerned co-pilot suggested they invite an off-duty JetBlue captain into the cockpit . Instead , Osbon `` abruptly left the cockpit to go to the forward lavatory , '' the affidavit says . The co-pilot used the opportunity to get the off-duty captain into the cockpit and change the combination to the door lock . When Osbon tried to enter his code into the cockpit door , the co-pilot announced over the public address system an order to restrain Osbon . Several passengers wrestled Osbon to the floor and restrained him . The lawsuit filed Wednesday does not specify the amount of damages the plaintiffs seek . CNN 's Aaron Cooper contributed to this report .
