The National Transportation Safety Board said Wednesday that the aircraft's wheels had very little rubber remaining and its brakes were severely damaged. The plane crashed upon an aborted takeoff around midnight Sept. 19.
"Oftentimes, we find that as we collect more information, the picture changes," said NTSB Public Affairs Officer Peter Knudson, who said the physical evidence of the crash – such as skid marks and the condition of the brakes – is being analyzed.
The cockpit voice recorder indicated that crewmembers expressed their belief that a tire blew as the jet was on the runway.
Having both suffered severe burns in the crash, Barker, 32, and DJ AM (real name: Adam Goldstein), 35, are now expected to recover fully.
