Analysis

The pilot stated that after lowering the nosewheel during the landing, he heard a 'popping sound' and immediately raised the nosewheel off the runway. After the aircraft slowed and the pilot could no longer hold the nosewheel off, the aircraft veered to the left as soon as the nosewheel touched down. The aircraft then went into a ditch at the left side of the runway and nosed over. An investigation revealed that a nut securing the nosewheel axle 'had backed off,' allowing the nosewheel to become misaligned.
