What is the purpose of diving the ducts on the aircraft?

Diving the ducts on an aircraft serves the crucial purpose of ensuring that the engine is in a Foreign Object Damage (FOD) free state. This process involves thoroughly inspecting the ducts and pathways that lead to the engine to identify any potential debris or foreign objects that could cause damage during operation. FOD can lead to severe engine failure or performance issues, so maintaining a FOD-free environment is essential for aircraft safety and operational efficiency.

The act of diving the ducts is part of routine maintenance practices to safeguard the engine and other critical components. By ensuring that these ducts are clear, aircraft maintenance personnel help to prevent costly repairs and enhance the overall reliability of the aircraft during flight operations. This preventative measure is vital for maintaining high safety standards in aviation and protecting the crew and passengers onboard.
