Narrative:

Helicopter was inadvertently overflown the turbine engine start count inspection. I also flew the aircraft after the overflying the turbine component start count inspection. On oct/thu/95 the mistake was discovered. The aircraft was immediately grounded until the turbine sections were replaced. There is a system installed to prevent this from occurring. Late reports and miscalculation caused the late identify of the impending violation of the component life inspection. The mishap could have been prevented by closer attention to detail, more frequent reporting of impending inspections by our base maintenance office, and more detail check of maintenance tracking records by the PIC and maintenance personnel. The company maintenance office will track and report component life inspections more frequently to assist maintenance in the field from inadvertently overflying these inspections.

Title: EMS HELI FLOWN PAST RECOMMENDED START CYCLE ON TURBINES.

Narrative: HELI WAS INADVERTENTLY OVERFLOWN THE TURBINE ENG START COUNT INSPECTION. I ALSO FLEW THE ACFT AFTER THE OVERFLYING THE TURBINE COMPONENT START COUNT INSPECTION. ON OCT/THU/95 THE MISTAKE WAS DISCOVERED. THE ACFT WAS IMMEDIATELY GNDED UNTIL THE TURBINE SECTIONS WERE REPLACED. THERE IS A SYS INSTALLED TO PREVENT THIS FROM OCCURRING. LATE RPTS AND MISCALCULATION CAUSED THE LATE IDENT OF THE IMPENDING VIOLATION OF THE COMPONENT LIFE INSPECTION. THE MISHAP COULD HAVE BEEN PREVENTED BY CLOSER ATTN TO DETAIL, MORE FREQUENT RPTING OF IMPENDING INSPECTIONS BY OUR BASE MAINT OFFICE, AND MORE DETAIL CHK OF MAINT TRACKING RECORDS BY THE PIC AND MAINT PERSONNEL. THE COMPANY MAINT OFFICE WILL TRACK AND RPT COMPONENT LIFE INSPECTIONS MORE FREQUENTLY TO ASSIST MAINT IN THE FIELD FROM INADVERTENTLY OVERFLYING THESE INSPECTIONS.
