This advisory circular (AC) provides guidelines that industry may use to develop and revise the minimum scheduled interval/tasking requirements for derivative or newly type-certificated aircraft and powerplants for Federal Aviation Administration (FAA) approval. This AC refers to these minimum scheduled interval/tasking requirements as the Maintenance Review Board Report (MRBR), Maintenance Type Board. After FAA approval, the requirements become a basis upon which operators develop their own individual maintenance programs. The report will become a living report for each type-certificate holder.

Use this AC to standardize development, implementation, and update of FAA-approved minimum scheduled maintenance/inspection requirements.
