During a postaccident examination of the engine and airframe, substantial damage to the firewall was discovered.

The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

Probable Cause: The pilot's failure to maintain pitch control during the landing, resulting in a hard landing.
