This technical report describes the F-15 programmed depot maintenance (PDM) process as performed at the Warner Robins Air Logistics Center (WR-ALC) in FYs 2004-2006. The average WR-ALC F-15 PDM visit runs behind schedule and lasts about four months. Also, PDM can wait a long time for parts; aircraft move through PDM steps out of sequence, with missing parts catching up with the aircraft when they become available, or cannibalize other aircraft.
