Narrative:

The #2 engine mini turbine was overflown by 110 cycles. Components overflown were the first stage wheel P/north #a serial #ob and the second stage wheel P/north #C, serial #od. Total time 1157.4 hours and 3110 cycles. These turbine wheels comprise mini turbine section which was installed on a turbine engine, serial #east. I have tracked the life and cycle limited items on a program I helped design for 5 yrs now. The program was written on computer program F. Recently, the company upgraded to computer program G. Since then, I have had a lot of problems with my computer in this program. Obviously, I have not paid proper attention to the life and cycle limited parts program. Since this occurrence, our new parts coordinator is undertaking the task of updating and printing weekly status reports of the aircraft cycle and life limited components. Copies are sent to each aircraft crew, the director of maintenance and also posted under the aircraft inspection status board. We are currently looking at different computer programs that are more comprehensive.

Title: MECH OF AN SMT ATX HELI FOUND THAT ONE OF THE ENGS HAD BEEN OPERATED 110 CYCLES OVER THE LIFE LIMITED REQUIRED CYCLES DUE TO CHANGE IN THE TYPE OF COMPUTER RECORD AND COMPLACENCY.

Narrative: THE #2 ENG MINI TURBINE WAS OVERFLOWN BY 110 CYCLES. COMPONENTS OVERFLOWN WERE THE FIRST STAGE WHEEL P/N #A SERIAL #OB AND THE SECOND STAGE WHEEL P/N #C, SERIAL #OD. TOTAL TIME 1157.4 HRS AND 3110 CYCLES. THESE TURBINE WHEELS COMPRISE MINI TURBINE SECTION WHICH WAS INSTALLED ON A TURBINE ENG, SERIAL #E. I HAVE TRACKED THE LIFE AND CYCLE LIMITED ITEMS ON A PROGRAM I HELPED DESIGN FOR 5 YRS NOW. THE PROGRAM WAS WRITTEN ON COMPUTER PROGRAM F. RECENTLY, THE COMPANY UPGRADED TO COMPUTER PROGRAM G. SINCE THEN, I HAVE HAD A LOT OF PROBS WITH MY COMPUTER IN THIS PROGRAM. OBVIOUSLY, I HAVE NOT PAID PROPER ATTN TO THE LIFE AND CYCLE LIMITED PARTS PROGRAM. SINCE THIS OCCURRENCE, OUR NEW PARTS COORDINATOR IS UNDERTAKING THE TASK OF UPDATING AND PRINTING WKLY STATUS RPTS OF THE ACFT CYCLE AND LIFE LIMITED COMPONENTS. COPIES ARE SENT TO EACH ACFT CREW, THE DIRECTOR OF MAINT AND ALSO POSTED UNDER THE ACFT INSPECTION STATUS BOARD. WE ARE CURRENTLY LOOKING AT DIFFERENT COMPUTER PROGRAMS THAT ARE MORE COMPREHENSIVE.
