## Discrepancy

THE FIBER LOCK NUT USED TO SECURE THE NOSE WHEEL AXLE BOLT APPEARS TO HAVE BEEN UNABLE TO MAINTAIN TORQUE. THIS LED TO THE DEPARTURE OF THE NUT FROM THE WHEEL AXLE BOLT AND CAUSED THE WHEEL ASSEMBLY TO BECOME FREE ON ONE SIDE OF THE MOUNTING FORKS RESULTING IN THE NOSE WHEEL LOCKING UP AND DAMAGING THE NOSE GEAR ASSEMBLY. IMAGES OF THE EVENT AND THE IPC WILL BE SENT TO 9-AMC-SDR-PROGMGR@FAA.GOV. THE OPERATOR OF THIS AIRCRAFT HAVE SEVERAL OTHER AIRCRAFT OF THE SAME MAKE MODEL WITH THE BERINGER BRAND WHEEL THAT ARE EXPERIENCING LOOSE FIBER LOCK NUTS AND ARE HAVING TO RETORQUE THE NUTS TO THE VALUE INDICATED IN THE TECNAM P2010 MM.
