"In service" aircraft are those in the forward fleet and available to the front line and training units. Aircraft "Under repair" are those in the depth fleet which are undergoing planned routine depth maintenance. "Other" aircraft are those awaiting depth maintenance; in long-term storage; undergoing trials/development activity or subject to modifications with industry.
Within the forward fleet controlled cannibalisation is conducted as part of normal business. Cannibalised aircraft are routinely returned to service when the necessary spare parts become available. Of the aircraft in the "Under repair" category, four are subject to controlled cannibalisation to support aircraft maintenance.
