## Analysis

THE COMMERCIAL PLT WAS PRACTICING SHORT FIELD LANDINGS FROM THE RIGHT SEAT ON A 7,498 X 100 FT ASPHALT RWY. THE PLT SAID HE ENCOUNTERED A THERMAL AT 10 FT AGL AND STALLED THE AIRPLANE. HE REPORTED THAT THE ACFT HIT HARDER THAN HE EXPECTED AND BOUNCED TWICE. HE STATED THAT HE ADDED THROTTLE AND MADE A GO-AROUND. HE LANDED SAFELY AND HE AND THE FBO VISUALLY INSPECTED THE ACFT, FINDING NO DAMAGE. LATER DURING ROUTINE MAINTENANCE, A MECHANIC FOUND SUBSTANTIAL DAMAGE TO THE FIREWALL AND NOTIFIED THE FAA.
