The engine may continue in service with subsequent inspections carried out as defined below.Due to erosion at leading edge, a repeat borescope inspection and power assurance check must be carried out within 300 flight hours. Subsequent borescope inspections and power assurance checks must be carried out at intervals not to exceed 300 flight hours. Due to cat 4 damage on hp vane segments, sub-sequent borescope inspections must be carried out at 400 flight hours max. 6&7 brg vent tube is cleaned before engine test
