A defective metal bracket was found during an investigation into the “partial equipment failure” that left six people injured during an incident on a jet bridge at Baltimore-Washington International Thurgood Marshall Airport on Saturday.

Officials with the Maryland Department of Transportation confirmed the find Sunday, per the Associated Press, adding that brackets on five other jet bridges made by the same manufacturer will be replaced.

Emergency crews responded to the incident on Saturday night, after a Southwest Airlines aircraft had arrived and deplaned at BWI following a flight from Punta Cana, in the Dominican Republic.

In a statement, Southwest Airlines had said the jet bridge failed while paramedics were assisting a passenger getting off the plane. The airline was not immediately available to specify whether the passenger was among the six injured.

Maryland’s Transportation Authority confirmed that the six passengers had been released from the hospital as of Sunday.

Officials also confirmed that a total of 33 jet bridges at BWI were inspected following the failure, and that the five other jet bridges needing new brackets were taken out of service until the parts could be replaced.

"Our passengers' safety is the top priority and BWI Marshall Airport has moved quickly to address this issue," state Transportation Secretary Pete Rahn said in a statement.

Shortly after the incident, BWI confirmed on Twitter that the incident did not have a significant impact on operations.
