A Static Test is a fundamental safety check performed on aircraft parts and structures while they're not moving. Think of it like pressure-testing a water bottle - engineers apply forces, pressure, or weight to aircraft parts to make sure they're strong enough to handle real-world conditions, but do this while the aircraft is stationary (static). This testing is crucial for ensuring aircraft safety and must be done before any new aircraft design or major modification can be approved for flight. It's different from flight testing because the aircraft stays on the ground, making it safer and more controlled.
