Japanese safety investigators concluded that work done by Bombardier on one of its Q400 turboprops before delivery to All Nippon Airways subsidiary Air Central caused a 13 March 2007 incident in which the aircraft's nose landing gear failed to deploy on landing at Japan's Kochi airport. The latest report by Japan's aircraft and railway accidents investigation commission ARAIC on the damage to the aircraft, registered JA849A, confirms an earlier finding that the failed deployment occurred because a 30mm (1.2in)-long strip of metal bushing moved and prevented the front landing gear doors from opening. However, while ARAIC originally found the bushing moved because a bolt dislodged, it has now concluded there never was any bolt because the manufacturer failed to install it following repair work carried out before delivery to the airline in July 2005.
