Families of the victims who died in last month’s deadly UPS plane crash in Louisville, Kentucky, filed the first wrongful death lawsuits against the shipper on Wednesday.

Both lawsuits, filed in Kentucky state court, argue UPS and other defendants should have known that the McDonnell Douglas MD-11 airliner “was in disrepair or was otherwise dangerous and unsafe.” After the accident, the Federal Aviation Administration grounded that particular aircraft fleet.
