## Analysis

THE PRIVATE PLT WAS PRACTICING LANDINGS IN HIS ACFT. DURING TAKEOFF GROUND RUN, WHILE MAKING A TOUCH AND GO LANDING, THE PLT REPORTED EXPERIENCING VIBRATIONS FROM BOTH MAIN GEAR AND HIS ACFT DEPARTED THE 5,000 X 50 FT RWY TO THE LEFT. THE PLANE TRAVELED 100 YDS, HIT A ROCK, AND NOSED OVER. A WITNESS REPORTED THAT THE ACFT APPEARED TO LAND HARDER THAN NORMAL. THE PLT SAID HE SUSPECTED THE RIGHT MAIN GEAR CAME LOOSE AT THE FUSELAGE ATTACHING POINT AND FORCED THE ACFT TO DEPART THE RWY. A POST ACCIDENT INSPECTION BY AN A & P MECHANIC WITH INSPECTION AUTHORIZATION, REVEALED DAMAGE TYPICAL OF THAT INCURRED DURING A LANDING ACCIDENT.
