## Analysis

THE TAILWHEEL (CONVENTIONAL GEAR) AIRCRAFT WAS EQUIPPED WITH A ROBERTSON STOL MODIFICATION. THE PILOT REPORTED THAT WITH THIS MODIFICATION, THE PLANE'S STALL SPEED WAS LOWERED TO 28 TO 30 KTS. WHILE IN THE TRAFFIC PATTERN, TOWER ASKED HIM TO KEEP HIS SPEED UP AND LAND LONG TO MAKE ROOM FOR ANOTHER AIRCRAFT THAT WAS FOLLOWING. A LANDING WAS MADE ON RUNWAY 22 WITH A HEAD WIND AT 10, GUSTING 15 KTS. DURING TOUCHDOWN, THE AIRCRAFT BOUNCED INTO THE AIR. THE PILOT THEN ADDED POWER, LANDED AND APPLIED BRAKES. SHORTLY THEREAFTER, THE AIRCRAFT NOSED OVER. NO MECHANICAL MALFUNCTIONS OF THE FLIGHT CONTROL OR BRAKE SYSTEM WERE REPORTED. THE PILOT STATED THAT HE WAS TRAVELING AT NOT OVER 15 MPH WHEN THE ACCIDENT OCCURRED.
