In 1996, RAND and the AFLMA initiated a joint study, Leveraging Logistics to Enhance the Effectiveness of Rapid Air Expeditionary Forces AEF. Over the course of this study, the AFLMAs focus was on deploying unit preparations. The AFLMA looked at three scheduled maintenance activities for the F-15DEs the number of phase inspections accomplished, the number of engines changed, and the number of egress time change items TCI replaced in preparation for a deployment. An area of concern was the significant spike in the number of egress TCIs that were being replaced on the aircraft scheduled for deployment Three alternatives were looked at for the replacement of egress TCIs a 36-month maintenance cycle which consolidates egress TCIs with the 36-month seat inspection, a 30-month maintenance cycle which requires the 36-month seat inspection to be done early, but is In sync with a 15-month AEF concept of operations, and a 12-month look-out policy which affords units more flexibility when schedulingreplacing egress TCIs. Both the 36-month and 30-month maintenance cycles result in increased parts cost due to an increase in the frequency of part replacements, a decrease in maintenance man-hours due to a decrease in the frequency of seat removals, and a possible decrease in aircraft downtime by eliminating any downtime specifically for egress TCI maintenance. The 12-month look-out policy is an extension of current procedures, allowing schedulers to look out further for any maintenance coming due. This policy will cause parts to be replaced ahead of schedule, resulting in an increased parts cost, though the increase is much less than a 30-month or a 36-month maintenance cycle. Under this policy there is no reduction in the number of seat removals, however, there is the possibility for a decrease in egress TCI maintenance events and aircraft downtime.
