   ASC 330-908 governs inventory accounting for airlines, where "inventory" consists of expendable spare parts, materials, and supplies held for internal consumption rather than sale. Expendable parts are recorded at cost in a current asset account akin to a prepaid expense, carry an allowance for obsolescence tied to the lives of the related fleets, and are charged to expense as used.
