Proposed is a use of our patented technology to assist aircraft maintenance management in check-in and check-out of CTKs which is time and labor intensive. We will adapt our proprietary system for use with existing CTKs and/or propose complete new CTKs which will accommodate reading of RFID tags. Information will be collected to define the variables to be considered, i.e. current CTKs used and their limitations and configurations (hand-carry, roll-around), number and type of tools included in target CTKs, number of different CTKs, etc.
