Narrative

ACFT ON STANDARD ILS RWY 21R APCH. THE APCH WAS STABILIZED. ALL GEAR WERE DOWN AND LOCKED. ALL '3 GREEN' LIGHTS OF THE LNDG GEAR INDICATORS WERE LIT AND OBSERVED. APCH SPD WAS NORMAL; ACFT CROSSED RWY 21R THRESHOLD; WHILE TRACKING ON GS AND ON LOC; FULL LNDG FLAPS WERE DEPLOYED. LNDG SPD WAS NORMAL. L AND R MAIN GEAR TOUCHED DOWN ON EITHER SIDE OF CTRLINE. AS NOSE GEAR TOUCHED DOWN; THE ACFT IMMEDIATELY WITHOUT WARNING VEERED VIOLENTLY TO THE L. PLT APPLIED MAX R LEG/FOOT PRESSURE TO R RUDDER IN ATTEMPT TO MAKE ACFT REMAIN ON THE CTRLINE BUT NOTICED ABSOLUTELY NO EFFECT. R RUDDER FELT STUCK. ACFT CONTINUED TO SKID UNCTLABLY TO THE L. RWY WAS WET AND SLIPPERY. ACFT EVENTUALLY VEERED OFF TO APPROX 10-15 FT OFF THE RWY L EDGE; COMPOSED OF MAINLY GRASS AND GRAVEL. PLT CONTINUED TO MODERATE R RUDDER PRESSURE AND BRAKING PRESSURE. EVENTUALLY; ACFT GAINED TRACTION AND BEGAN TO STEER TO THE R; RETURNING BACK ONTO THE ASPHALT HARD RWY SURFACE. DUE TO THE WETNESS AND POTENTIAL BLACK ICING CONDITION ON THE SURFACE; THE ACFT TURNED AROUND AND CAME TO A FULL STOP; BACK ON THE RWY ASPHALT SURFACE; FACING THE OPPOSITE DIRECTION. TWR CTLR ASKED WHETHER THE AFT HAD COME IN CONTACT WITH ANY KNOWN PATCHES OF BLACK ICE ON THE RWY. THE PLT REPLIED THAT HE DID NOT KNOW. THE CTLR TOLD PLT TO CHANGE TO GND FREQ. PLT THEN ENGAGED ONLY EMER GND CLRNC SWITCH; COM #1; TO REMAIN IN COM WITH TWR. THE CTLR RADIOED MECHS ON FIELD TO CALL FOR THE TUG. INITIAL OBSERVATIONS: THE NOSE GEAR REMAINED INTACT AND WAS RAISED ON THE TUG. THE ACFT WAS TOWED BACK TO THE HANGAR. FAA FSDO OFFICIAL WAS ON THE SCENE. WHEN EXAMINING THE NOSE GEAR UNDERCARRIAGE; THE MECHS FOUND THAT THE ENG MOUNT PORTION WHICH CONNECTED TO THE NOSE GEAR HYD ACTUATOR AND THEN TO THE NOSE GEAR TRUNNION; WAS CRACKED. NO HYD FLUID LEAK WAS FOUND. THE MECHS COMMENTED THAT THE PLT NEVER HAD ANY CHANCE OF REGAINING STEERING CTL OF THE ACFT. BROKEN AND CRACKED ENG MOUNT IN PIPER PA46 ACFT IS A KNOWN AND RECURRING ISSUE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE LCL FAA FLT SAFETY INSPECTOR WAS AT THE FIELD AND INVESTIGATED THE INCIDENT WHEN THE ACFT WAS TOWED IN THE HANGAR. THE MAINT PEOPLE AND THE INSPECTOR CONCLUDED THE LOWER MOTOR MOUNT WAS CRACKED PRIOR TO LNDG AND FAILED ON LNDG WITH THE NOSE LNDG GEAR LOSING SUPPORT. THE PIPER PA46 MOTOR MOUNTS HAVE A KNOWN RECORD OF FAILURES.
