Question

Which type of engine FOD does not require engine fan blade, turbine, module removal and replacement?

1) Bird strike
2) Foreign object debris
3) Hail damage
4) Water ingestion

Answer 1

Water ingestion generally does not require engine fan blade, turbine, or module removal and replacement due to an engine's ability to handle water without sustaining permanent damage.

Step-by-step explanation:

The type of engine Foreign Object Debris (FOD) that typically does not require engine fan blade, turbine, or module removal and replacement is water ingestion. Water ingestion can cause temporary issues such as a reduction in engine thrust or stalling, but the engines are generally designed to handle significant amounts of water without sustaining permanent damage. In contrast, bird strikes, foreign object debris, and hail damage often cause physical damage to fan blades and turbines that necessitate careful inspection and potentially removal and repair or replacement of the damaged parts.
