Learjet Denies Responsibility for Travis Barker Plane Crash

"Learjet alleges that any and all conditions [of the aircraft], if any there were, were solely a result of the failure to properly maintain and service the aircraft," say the papers, filed Jan. 16 in Los Angeles.
Both pilots of the plane, as well as Barker's assistant Chris Baker, 29, and bodyguard Charles Still, 25, perished in the crash. Barker and DJ AM were hospitalized for weeks with serious burns.
Barker, DJ AM, Still's mother and Baker's widow have filed wrongful death lawsuits against various corporations they allege were responsible. Baker's widow and DJ AM are also suing the estates of the two pilots.
Learjet added that the damages suffered by the plaintiffs were "either excessive, exaggerated, unreasonable, speculative, inflated or otherwise unnecessary and/or unrelated to the alleged incident."
Peter Knudson, a spokesman for the National Transportation Safety Board, which is investigating the crash, recently told PEOPLE, "It is far too early to say who or what is to blame for the crash," adding that investigations can take more than a year.
"Learjet's lawyers get paid by the hour to regurgitate stock paragraphs from word processing programs in every case they're involved in," said Barker's lawyer Walter J. Lack. "This case is no exception."
