MNT.2:1 - Problem frame

Use this pattern when a recurring maintenance task, inspection interval or proposed technology needs a reason to be retained or changed. A calendar says “replace every year,” but the planner cannot explain which failure this prevents or why a different task would be worse.

Choose a reusable maintenance policy for the identified functioning and failure situation. Here a policy states which task applies and under what condition it is performed. The first result can be a justified decision to retain the current policy. A one-off response to today’s condition belongs in MNT.6; a fleet-wide support and work decision belongs in MNT.13.
