Key Takeaways:

A range of limit switch malfunctions (defective, ice-contaminated, out of adjustment, or physically bent/intermittent) were reported across multiple aircraft types.
These failures primarily affected critical aircraft systems such as wing flaps and landing gear, leading to issues like incomplete flap extension, continuous motor operation, incorrect indicator lights, or gear warning activations.
All reported incidents were resolved by either replacing the faulty limit switch or adjusting its rigging to proper specifications.
