Notice 8900.74, Parts Marking, was recently issued by the Federal Aviation Administration (FAA). The agency clarifies how operators and maintenance providers should treat parts whose identification information becomes missing or illegible during the normal course of operations and maintenance.

The Notice stresses that when identification data for a component is compromised it does not automatically mean the part or aircraft is not airworthy. The FAA identifies other methods, such as visual inspections, operational or functional checks and reference to illustrated parts catalogues or component maintenance manuals as possible alternatives for determining an article’s identity and airworthiness.
