What can be used to verify the integrity of the static system after repairs?

The static pressure test is the most appropriate method to verify the integrity of the static system after repairs. This test involves applying a known pressure to the static system and monitoring for any leaks or discrepancies in pressure readings. By ensuring that the system can maintain this pressure without significant loss, the technician can confirm that the repairs made have successfully restored the system to a functioning state.

This testing method is critical in aircraft maintenance, as a compromised static system can lead to inaccurate altitude and airspeed readings, which are essential for safe flight operations. A static pressure test allows for a direct evaluation of the system's seals, connections, and overall integrity.

Other methods, while important in various contexts, do not specifically address the verification of a static system's integrity in the same way. For instance, electromagnetic testing is generally used to evaluate the material properties of components, shock loading can diagnose strength and failure under sudden forces, and vibration analysis focuses on assessing the health of mechanical components under operational conditions. None of these methods directly lead to verifying static pressure retention and the associated performance of the static system, which is the primary concern after repairs.
