The ST8842 Tap Test Tool is a dedicated aircraft inspection tool designed for tap testing of composite and honeycomb structures. By producing a controlled tapping sound and allowing technicians to evaluate changes in acoustic response, the tool supports the identification of potential defects such as disbonding, delamination, or other structural anomalies during aircraft maintenance inspections.

The ST8842 is specifically identified in Boeing maintenance documentation as a tap test tool available from Boeing Spares. It is also listed by aviation tooling suppliers as a Boeing Tap Test Tool, making it suitable for non-instrumented composite structure inspection in professional aircraft MRO environments.
