(-23) DURING LANDING ROLLOUT, GRUMMAN G-164A, N5416, WAS SUBSTANTIALLY DAMAGED WHEN THE RIGHT HAND BRAKE FAILED, CAUSING THE AIRCRAFT INTO A GROUND LOOP. THE PILOT REPORTED THAT WHILE ALL 4 WINGS APPEARED WRINKLED, THE LOWER RIGHT WING WAS BENT UP. THE RIGHT HAND MAIN LANDING GEAR ASSEMBLY WAS ALSO SEPARATED FROM THE AIRFRAME.
