Contractors did the aircraft maintenance aside from the day to day that the US squadrons did. Phases/engine change. Helo maintenance is pretty intensive, ain’t seeing the Talis doing that in house. All the more reason those birds could have easily been put out of action with a hammer, let alone thermite grenades (the preferred method). And pilot skills in high density altitude (Afghanistan) perish quickly if you aren’t getting hours.
GLAD to see all your maintenance comments - keep us appraised, okay??
