It could be and the landing system is called "LI" Inductor...These switch are adjusted with a "gram gauge" and are sensitive. Don't adjust these with needle nose pliers. Is this a new job you just inherited or did this just start happening. How is the approach to the floor in both direction? Does it feel OK!

If it's coming in out of control and just stopping...Most likely a ground in the loop...On the controller will tell you type of control..Sounds like an REL...You should have 3 armatures on generator?
