Incorrect, AIR 5376 Phase 3.2 (HUG 3.2) Reassessment revised this to 10 airframes only from the original plan of 49. The remaining airframes have been managed out to a max of 6,000hrs or a specific Fatigue Life Expended Index (FLEI) of 0.64 for ARDU jets, 0.85 for all non-CBR jets, and 1.0 for CBR jets through restrictions on use, scheduling and monitoring. The RCAF have received the 18 jets with the lowest FLEI.
