Narrative:
Our tracking program has a software problem tracking 'cycle' retirement items for this particular model engine (LTS101-750B-1). The company who created this program (wxwy) has not yet corrected the problem. I have been manually reviewing the reports for tracking these components. I have been overloaded recently with new aircraft entering the fleet and neglected to review this report. The component was overflown for 16 days/22.9 hours (56.9 cycles exceeded). There are only X amount engines of this model in the fleet. Until the vendor of the computer software corrects the problem I will create computerized spreadsheets in a basic program to track these components. Callback conversation with reporter revealed the following information: the reporter stated the mbb BK117 is a helicopter and the overtime part was a turbine engine disc with an airworthiness directive on the life cycle. The reporter said the computer software used to track this part is new and did not alert or call out replacement. The reporter stated the error was discovered in a records review but not in time to avoid the overtime.
Original NASA ASRS Text
Title: AN MBB BK117 HELI TURBINE ENG DISC EXCEEDED TIME FOR REPLACEMENT BY 22 PT 9 HRS AND 56 PT 9 CYCLES DUE TO COMPUTER TRACKING PROBS.
Narrative: OUR TRACKING PROGRAM HAS A SOFTWARE PROB TRACKING 'CYCLE' RETIREMENT ITEMS FOR THIS PARTICULAR MODEL ENG (LTS101-750B-1). THE COMPANY WHO CREATED THIS PROGRAM (WXWY) HAS NOT YET CORRECTED THE PROB. I HAVE BEEN MANUALLY REVIEWING THE RPTS FOR TRACKING THESE COMPONENTS. I HAVE BEEN OVERLOADED RECENTLY WITH NEW ACFT ENTERING THE FLEET AND NEGLECTED TO REVIEW THIS RPT. THE COMPONENT WAS OVERFLOWN FOR 16 DAYS/22.9 HRS (56.9 CYCLES EXCEEDED). THERE ARE ONLY X AMOUNT ENGS OF THIS MODEL IN THE FLEET. UNTIL THE VENDOR OF THE COMPUTER SOFTWARE CORRECTS THE PROB I WILL CREATE COMPUTERIZED SPREADSHEETS IN A BASIC PROGRAM TO TRACK THESE COMPONENTS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE MBB BK117 IS A HELI AND THE OVERTIME PART WAS A TURBINE ENG DISC WITH AN AIRWORTHINESS DIRECTIVE ON THE LIFE CYCLE. THE RPTR SAID THE COMPUTER SOFTWARE USED TO TRACK THIS PART IS NEW AND DID NOT ALERT OR CALL OUT REPLACEMENT. THE RPTR STATED THE ERROR WAS DISCOVERED IN A RECORDS REVIEW BUT NOT IN TIME TO AVOID THE OVERTIME.
