The AS9100 Rev D standard does not use the aviation acronym PEARs (People, Environment, Activities, Resources), but instead talks about human factors and human error. This concept only appears in three clauses. First, in a note to clause 7.1.4, Environment for the operation of processes, where it highlights that a suitable environment can be a combination of human and physical factors. Secondly, in clause 8.5.1, Control of Production and service provision, where one controlled condition that should be included are actions to prevent human error. Lastly, clause 10.2.1b where it talks about including human factor considerations when determining the causes of process nonconformities while investigating corrective actions.
