Narrative:

Shot a normal approach. On short final I noticed the runway had been ploughed down the middle but the edges had not been ploughed. Upon landing my aircraft started pulling to the left. I tried to correct but it was to late. My left wheel hit the snow berm and started turning me to the left. I spun around off the runway. After realizing what happened I pulled out of the the snow bank by throttling up the engines. This caused snow to damage my flaps. I was in a state of shock and did not want to get in trouble. I wasn't thinking clearly. After unloading my cargo on the ramp I took back off to my next destination. When shooting my next approach my flaps would not come down. I flew back to my base and landed without event.
