## Analysis

UPON LANDING FOLLOWING A NORMAL 70 KNOT FINAL APPROACH THE AIRCRAFT INITIALLY TOUCHED DOWN ONE-THIRD OF THE WAY DOWN THE 2500 FT GRASS RUNWAY. A BOUNCE CARRIED THE AIRCRAFT TO A POINT HALFWAY DOWN THE RUNWAY WHERE THE AIRCRAFT LANDED IN A FULL STALL. THE PILOT COMMENCED BRAKING BUT THE AIRCRAFT VEERED OFF THE RIGHT SIDE INTO TREES AND A DITCH. AN EXAMINATION OF THE ACFT LOGBOOK REVEALED THAT THE RIGHT BRAKE LININGS WERE REPLACED TWICE SINCE 04-23-84. AN EXAMINATION OF THE BRAKE SYSTEM ITSELF REVEALED NOTHING THAT WOULD CAUSE INADVERTENT BRAKE LOCKING, HOWEVER THE PILOT DESCRIBED THE GRASS RUNWAY SURFACE AS DRY BUT SLIPPERY.
