What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot statement:
After a stable approach and normal soft landing on the centerline of the runway, I held the nose wheel off until it settled and began to apply the brakes. As soon as brakes were applied, the plane began to pull left so I applied right rudder and more right braking but it was not enough to stay on the runway. At this point I was concerned that we were on ice and sliding, there was no sound of grinding or indication of a flat tire. I was approaching a taxiway A3, we were too fast to try and make the turn, I was fearful that if I over corrected that I could induce a slide to the right and hit the taxiway sign so I chose to steer between the taxiway lights and head for the grass, still unaware of the flat tire. We came to a stop approximately 25 feet into the grass.
