In the CT line of aircraft, it is very common for pilots to land left. It doesn't seem to matter if they are students or high-time pilots making the transition. The problem is probably related to the width of the cabin, the lack of a visible cowling, and the curved shape of the panel.
The problem eventually fixes itself as the pilots get used to the sight-picture. Many have reported that an indicator stuck to the windscreen has helped immensely. What I did was just take a few dots and stick them on the inside of the windscreen, showing proper alignment. I used a bit of the sticky section of a Post-It, about the size of a pencil eraser. Others have used map tape, or just a few marks from a grease pencil.
Just align the plane with a long straight line on the ground, and put the dots on the windscreen so they align with the line. Easy, quick, fix.
