CUTS
POSSIBLE CAUSES
Cuts are most often caused by foreign objects present on runways or taxiways.
RECOMMENDATION
If cuts reach the carcass ply or belt cut limits, the tire must be removed from the aircraft.
If the Cut Depth Limit (CL) has not been reached, but the cut length exceeds the Length Limit (LL), remove the tire from the aircraft.
* Tires with cuts reaching more than 40% of the actual number of plies, or 40% of the belts for radial tires, must be scrapped.
* WARNING
Do not probe cuts or embedded foreign objects while tire is inflated.
Note:
CL designates the depth from the groove bottom to the outer carcass ply (bias) or outer belt (radial). Neither the reinforcing fabric (bias) nor aramid cord protector (radial) shall be confused with the belt or carcass plies. Refer to the CL and LL limits table.
