<p>No Fault Found (NFF), No Trouble Found (NTF) or No Defect Found (NDF) are terms used in the field of maintenance, where a unit is removed from service following a complaint of a perceived fault by operators or an alarm from its BIT (built-in test) equipment. The unit is then checked, but no anomaly is detected by the maintainer. Consequently, the unit is returned to service with no repair performed.</p> <p>See also: <a href="https://en.wikipedia.org/wiki/No_fault_found">NFF</a></p>
