In addition, the front floor sections, front belly sections, front belly skin, center pedestal, and numerous stringers and angles were damaged.
The airplane was operated by a flying club in South Bend, Ind. The flying club was unable to determine when the damage took place, however, it is possible that the damage was associated with nosewheel damage that was discovered earlier on Dec. 2, 2013.
The NTSB determined the probable cause as the pilot involved and the phase of flight when the damage was incurred were not determined.
