Who is responsible for performing the static system leakage checks as part of maintenance?

The responsibility for performing static system leakage checks is typically assigned to an aviation maintenance technician. These checks are essential for ensuring the integrity of the aircraft's altimeter and other pressure-sensitive instruments that rely on a closed static system. The aviation maintenance technician has the expertise and training necessary to carry out these checks correctly and interpret the results.

In this context, static system leakage checks are vital for flight safety, as any leaks could lead to inaccurate altitude readings, which can jeopardize safe aircraft operation. Technicians utilize specific equipment and procedures to identify and assess leaks in the static system, ensuring that all components meet regulatory standards and function reliably.

Pilots, flight engineers, and safety inspectors also play critical roles in aircraft operations but are not primarily responsible for performing these specific maintenance checks. Instead, they may rely on the findings of the maintenance technicians to inform them of the aircraft's airworthiness before flight. Therefore, the role of the aviation maintenance technician is essential and aligns with regulatory expectations for aircraft maintenance practices.
