During an annual inspection on February 26, 2014, a mechanic discovered buckling, compression, and kinking of both firewall sections. 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. The flying club was unable to factually determine when the damage took place; however, it is possible that the damage was associated with nosewheel damage that was discovered earlier on December 2, 2013.
