WICHITA, Kan. (AP) — A federal judge has summarily ruled in favor of Boeing and one of its suppliers in a whistleblower lawsuit that alleged the company’s planes were unsafe.

U.S. District Judge Monti Belot sided with the aircraft maker and one of its California-based suppliers, Ducommun Inc., in the lawsuit filed in 2005 by three former Wichita workers who claimed Boeing defrauded the U.S. government by using “bogus parts” in a $1.6 billion contract for 24 planes.

Wednesday’s 79-page decision rejected all claims brought by former employees Taylor Smith, Jeannine Prewitt and James Ailes. Their attorney, Corlin Pratt, said in an email that his clients are “extremely disappointed in the ruling” and are continuing to analyze the lengthy court opinion.

Boeing was reviewing the decision and its spokesman had no immediate comment.
