## Discrepancy

DURING A SCHEDULED INSPECTION CRACKING WAS FOUND ON THE AFT SIDE OF THE HEATED LIP ASSEMBLY, THE CRACKING WAS IDENTIFIED BY VISUAL INSPECTION. THE PILATUS PC-12 REPAIR INVOLVES REPLACEMENT OF THE ENTIRE HEATED ANTI-ICE LIP ASSEMBLY P/N 530.24.12.151, OR P/N 530.24.12.155 THE HEATED LIP ASSY. SEEMS TO HAVE A CONSISTENT FAILURE RATE AROUND 1500- 4000 HOURS OF OPERATION. WE HAVE REPLACED SEVERAL HEATED LIP ASSEMBLIES WITHIN OUR FLEET. THIS CURRENT LIP WAS ON SINCE 12/2020 AND HAD ACCUMULATED A TOTAL TIME IN SERVICE OF 4,167.4.
