Analysis

The pilot was returning to land at the non-towered airport after aborting a cross country flight because of deteriorating weather conditions. The pilot said he was focused on the proper glide path during the final approach and that he forgot to lower the landing gear. The airplane slid to a stop on the runway with the landing gear still retracted. There were no injuries to the solo pilot on board, but substantial structural damage to the belly of the fuselage.
