An F-15 Eagle flies over the Pacific during Valiant Shield Aug. 9. The directive follows Nov. 27 findings stemming from the investigation of an F-15C mishap that resulted in the loss of that aircraft on Nov. 2 . Based on those new findings, all F-15 A through D models will undergo a stand down that will require additional inspections and possible repair actions.
