Narrative:

At approximately XA30 we were inbound from lse to ane and had every intention on canceling our IFR flight plan after conducting the visual approach. We simply forgot. The approach controller got ahold of my boss and was quite upset (understandably). I recall us both being very tired and I would definitely say that this played a role in our mistake. We obviously need to be more aware of our condition and learn better how to evaluate this to stay as safe as possible.
