AUSTIN (KXAN) -- The National Transportation Safety Board (NTSB) released a preliminary report on the plane crash in Laredo that killed an Austin tech entrepreneur mid-June. According to the report, a business jet, a Textron 680A, carrying six people crashed June 16 around 10 p.m. onto a major Laredo highway. One person, identified as Joshua Baer, was killed and five others were injured.  The Federal Aviation Administration said the aircraft departed from San José del Cabo, Mexico, and was headed to Austin, Texas.  According to the NTSB report, the fight crew noticed an “unusual vibration” early in the flight and described it as a “low frequency vibration and a humming noise.” “It sounds like a fan is on … you can feel it in the dashboard,” the NTSB reported. The pilots contacted NetJet, a private jet company, and reported that the vibration had gone away, the report states. A maintenance controller suggested that the vibration could have been caused by a cooling fan in the instrument panel. During a continued conversation with the maintenance controller and Flight Operations Duty Manager, it was determined the flight could proceed to its destination.  As the plane approached the U.S.-Mexico border, the pilots received another message indicating a low fuel pressure in the right fuel system. Investigators said shortly after, three other messages displayed indicating low fuel, the heat was inoperative on the right-hand side and an electrical system failure also affecting the right-hand side.  According to the report, the pilots prepared for an emergency landing and requested they divert to the Laredo International Airport. Investigators say they were cleared to land, but as they approached, both engines "flamed out." The pilot asked if there were any open pastures or fields to avoid landing on the highway. “It’s just going to be the main highway and that’s just about it,” the air traffic controller said.  The plane crashed on the northbound lanes of the Bob Bullock Loop, also known as Loop 20, about one mile southeast of the airport, the report states.  Video surveillance and doorbell camera footage showed flames around the airplane as it was on its final descent. As the plane touched down the northbound lanes of traffic, it “sheared off light poles, struck a vehicle and came to rest straddling the right-hand edge of an overpass,” the NTSB reports. The captain sustained serious injuries while the co-pilot and three others received minor injuries, the report states. A person in a vehicle hit by the plane on the highway also received minor injuries.  According to the report, the airplane was relocated to a secure facility for further examination.  The NTSB report is preliminary and is subject to change.
