As reported to the FAA. Reports are unverified, and codes are left as the FAA publishes them.

What was found

UPON REPLACING THE NR 1 MAIN TIRE THAT WAS SKIDDED OFF AND BLEW OUT ON LANDING, THE BRAKE TORQUE PLATE WAS FOUND CRACKED AT FWD UPPER BUSHING. IT WAS NOTED THAT BOTH THE FWD UPPER AND THE REAR LOWER BUSHINGS HAD BEGUN TO CREEP OUT. THIS COULD POSSIBLY HAVE BEEN A CONTRIBUTING FACTOR IN THE BRAKES NOT RELEASING PROPERLY, AND CAUSING THE TIRE TO BLOW OUT.
