Aviation Computerized Maintenance

All repair and supply activities were subject to detailed tracking in two separate databases Aviation Computerized Maintenance System (ACMS) and Aviation Maintenance Management System (AMMIS). The ACMS database tracks all individual parts installed on individual aircraft, flags the required maintenance, and records the history of repairs using each part s unique serial number. The AMMIS database in contrast tracks every step of the process once the part comes off the aircraft. It tracks demand requisitions (orders) placed to the warehouse, and the shipment of good parts to the air stations and maintenance facility, as well as the receipt of failed parts (carcasses), their shipment to vendors or in-house for repair, and their induction back into the system. Historically, there was no connection between the AMMIS and ACMS systems, and there was no advance information regarding impending demands or repair lead times.
