Narrative:

Tail rotor assembly was replaced on aircraft X with a freshly rebuilt assy. Entry number 5 on maintenance worksheet log page entered and signed off by local mechanics. After pulling a short term due list the tail rotor tt straps indicated they had minimal time left on them. I and the day pilot both questioned the remaining time to both mechanics and was reassured that there was a glitch in software and there was adequate time remaining. The previous short term due list had hand written 'cw' indicating the inspections were complied with. This was also reflected as signed off with an rii sign off; in form XXXX in the maintenance log. We were informed that software was the issue on clearing the inspection item off of the short term due list. This was again questioned the following day by myself and pilot; we were reassured that the issue was in software. This questioning continued for three days at xa:36 I received a call from mr. X to immediately take the aircraft out of service. He then explained to me that there was an issue with the tt straps and the likelihood that they had been overflown.all log book paperwork and maintenance entries appeared in order and the continued reassurance by both mechanics; one the area lead mechanic; we continued to perform our duties and fly dispatched flights.to have a better maintenance tracking procedure especially when using swapped aircraft components.
