Factual narrative

AS THE PLT APPLIED BRAKES DURING A FULL STOP LANDING, THE RIGHT BRAKE FAILED. THE PLT THEN MANEUVERED THE ACFT OFF THE PAVED LANDING SURFACE IN AN ATTEMPT TO GET IT TO ROLL TO A STOP. THE RIGHT LANDING GEAR STRUT COLLAPSED. THE ACFT THEN SLID INTO A FENCE AND STOPPED. AN EXAMINATION OF THE RIGHT BRAKE ASS'Y REVEALED EXTREMELY THIN INNER AND OUTER BRAKE PADS. SOME PORTIONS OF THE PADS WERE WORN COMPLETELY AWAY. FURTHER EXAMINATION REVEALED THAT THE O RING SEAL AROUND EACH BRAKE CYLINDER WAS PROTRUDING FROM THE CYLINDER ASS'Y. THE RIGHT TIRE EXHIBITED HEAVY HYDRAULIC FLUID STAINING. A LOGBOOK ENTRY OF 1/25/85 STATED THAT THE BRAKE LININGS AND SEALS FOR BOTH BRAKES WERE REPLACED DURING THAT INSPECTION.
