Narrative:

During my preflight, engine running and emergency brakes on, I was programming my GPS when I suddenly felt the plane moving. When I looked up there was no time for evasive action. I ran into another aircraft and I shut down as soon as possible, only doing minimum damage to both aircraft. I believe the accident was caused by a faulty brake caliper.
