What is a potential risk of not clearing fuel after a no light off?

In the context of a no light off scenario during engine start, failing to clear fuel presents a significant risk of starter overheating. When fuel is not cleared, and the starter continues to crank the engine without ignition, it may lead to excessive and prolonged operation of the starter. This sustained operation generates heat, potentially pushing the starter beyond its operational limits, leading to overheating.

If the starter overheats, it can result in damage to internal components, increasing the likelihood of failure either during the current start attempt or potentially during future operations. Managing fuel and ensuring proper engine start procedures is crucial for preventing unnecessary wear and tear on the starter and ensuring safe aircraft operation. This understanding is essential for pilots and maintenance personnel to mitigate risks associated with engine starts.
