Narrative:
Landing at yow runway 32. We crossed the threshold at approximately our reference speed of 118 KIAS upon landing I first landed on the left main gear (due to light crosswind from the left) almost immediately thereafter I placed the right main gear down, the aircraft began to sway rather violently. I used what available resources I had to my disposal ie, nose wheel steering, differential power to control the aircraft from exiting the runway. The aircraft skidded approximately 3500 ft with all 4 main tires locked. All main tires blew in subsequent skidding and a fire started on left main gear. Passengers were evacuated from right side of aircraft with no injuries. Investigation revealed a major compound failure of brake/anti-skid system which allowed us to touch down with all main tires locked. Damage was severe to tires and rims including brake systems. I feel that situation was handled as best as possible considering situation. According to manufacturer technicians the light transport is not capable of landing with locked brakes. This is the first known incident of this type of failure on an light transport aircraft worldwide. I feel an investigation should be launched into the possible cause of this failure and corrective actions: possibly an a.D. Should be issued on this aircraft for this failure. The possible outcome of this may have been quite different if the aircraft would have slid sideways or off the runway.

Title: LTT LANDS WITH LOCKED BRAKES, BLOWS 4 TIRES AND HAS A FIRE IN ONE WHEEL.
Narrative: LNDG AT YOW RWY 32. WE CROSSED THE THRESHOLD AT APPROX OUR REF SPD OF 118 KIAS UPON LNDG I FIRST LANDED ON THE L MAIN GEAR (DUE TO LIGHT XWIND FROM THE L) ALMOST IMMEDIATELY THEREAFTER I PLACED THE R MAIN GEAR DOWN, THE ACFT BEGAN TO SWAY RATHER VIOLENTLY. I USED WHAT AVAILABLE RESOURCES I HAD TO MY DISPOSAL IE, NOSE WHEEL STEERING, DIFFERENTIAL PWR TO CTL THE ACFT FROM EXITING THE RWY. THE ACFT SKIDDED APPROX 3500 FT WITH ALL 4 MAIN TIRES LOCKED. ALL MAIN TIRES BLEW IN SUBSEQUENT SKIDDING AND A FIRE STARTED ON L MAIN GEAR. PAXS WERE EVACUATED FROM R SIDE OF ACFT WITH NO INJURIES. INVESTIGATION REVEALED A MAJOR COMPOUND FAILURE OF BRAKE/ANTI-SKID SYS WHICH ALLOWED US TO TOUCH DOWN WITH ALL MAIN TIRES LOCKED. DAMAGE WAS SEVERE TO TIRES AND RIMS INCLUDING BRAKE SYSTEMS. I FEEL THAT SITUATION WAS HANDLED AS BEST AS POSSIBLE CONSIDERING SITUATION. ACCORDING TO MANUFACTURER TECHNICIANS THE LTT IS NOT CAPABLE OF LNDG WITH LOCKED BRAKES. THIS IS THE FIRST KNOWN INCIDENT OF THIS TYPE OF FAILURE ON AN LTT ACFT WORLDWIDE. I FEEL AN INVESTIGATION SHOULD BE LAUNCHED INTO THE POSSIBLE CAUSE OF THIS FAILURE AND CORRECTIVE ACTIONS: POSSIBLY AN A.D. SHOULD BE ISSUED ON THIS ACFT FOR THIS FAILURE. THE POSSIBLE OUTCOME OF THIS MAY HAVE BEEN QUITE DIFFERENT IF THE ACFT WOULD HAVE SLID SIDEWAYS OR OFF THE RWY.
