Cancel Fault

Explanation

Technicians, supervisors, and crew leads can cancel a fault from the Task Details or Fault Details page. Use this option when the fault needs to be moved to a cancelled state and all related assignments, references, and records are handled consistently.

Clicking Cancel Task opens the Cancel Task assistant. The assistant displays indicators for any existing Part Issue, Part Reserve, and Tools Checked-in records, so that dependencies are visible before cancellation.

The assistant requires a Cancellation Cause and a Cancellation Comment before the cancellation can be saved.

Prerequisites

• The task must be in Active status. This includes tasks associated with faults where No Fault Found has already been applied.
• At least one Cancel Cause must be configured in Aviation Maintenance > Solution Configuration > Maintenance Execution Basic Data > Cancel Causes, with the Work Task toggle enabled.
