What would likely happen if a pre-flight engine inspection is skipped?

Skipping a pre-flight engine inspection greatly increases the risk of overlooking critical issues that could lead to a safety hazard. Pre-flight checks are essential for identifying potential problems, such as leaks, mechanical abnormalities, or wear and tear that could compromise engine performance. If these issues are not detected and addressed, they could lead to catastrophic failures during flight, posing a significant threat to the safety of the aircraft, crew, and passengers. Regular inspections are designed to catch these hazards before they develop into serious issues, helping to ensure operational safety. This highlights the critical role of thorough checks in maintaining aviation safety standards.
