## Analysis

THE STUDENT PLT LANDED THE ACFT AND ALLOWED IT TO SLOW BEFORE APPLYING BRAKES. THE STUDENT STATED, THE ACFT THEN BEGAN VEERING TO THE RIGHT SIDE OF THE RWY. ATTEMPTS BY THE STUDENT AND CFI TO CORRECT THE SITUATION WERE INEFFECTIVE AND THE ACFT DEPARTED THE RIGHT SIDE OF THE RWY. IT MADE A SHARP RIGHT TURN AND DESCENDED DOWN SLOPING TERRAIN. THE NOSE GEAR THEN COLLAPSED AND THE ACFT NOSED OVER INVERTED. INSPECTION OF THE BRAKE SYSTEM REVEALED A LEAKING HYDRAULIC LINE 90 DEGREE FITTING AT THE BRAKE. THE SYSTEM WAS INSPECTED 10 MONTHS AND 103 FLT HOURS PRIOR TO THIS ACCIDENT.
