Sub Contractors are restricted to tasks that do not require base maintenance or engine changes. In aviation maintenance regulation, base maintenance and engine change are large-scale, specialized activities that need facilities, approvals, and a formal release to service from the organisation with base/engine capabilities. Therefore a Sub Contractor may perform only smaller, non-base tasks authorized within the primary maintenance organisation’s scope, not base maintenance or an engine change. That’s why the best choice states that no base maintenance or engine change may be performed by a Sub Contractor.
