## Analysis

THE PLT OF THE HOME BUILT ACFT WAS PRACTICING TOUCH-&-GO LANDINGS. WHILE CLIMBING OUT AFTER THE 5TH LANDING, THE PLT'S CANOPY UNLATCHED & OPENED. THE PLT ATTEMPTED TO CLOSE THE CANOPY & NOSED THE ACFT DOWN TO MAINTAIN A SAFE AIRSPEED. WHILE TRYING TO CLOSE THE CANOPY, THE ACFT DESCENDED & STRUCK THE RWY HARD & BOUNCED BACK IN THE AIR. THE PLT HELD THE CANOPY PARTLY CLOSED AND CIRCLE TO LAND ON RWY 4. JUST BEFORE LANDING, HE LET GO OF THE CANOPY & REDUCED THE POWER. AN INSPECTION OF THE ACFT REVEALED THE SUPPORT TUBING FOR THE LANDING GEAR & THE TAILWHEEL SUPPORT TUBE WERE BENT. ALSO, APRX 4 INCHES HAD SHEARED FROM THE TIPS OF BOTH PROP BLADES.
