Investigator assessment
Analysis narrative
The pilot reported that, during a straight-in approach, he forgot to extend the landing gear and that he landed with the landing gear retracted. Subsequently, the airplane slid on the runway before it came to rest. The airplane sustained substantial damage to the lower fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
