Narrative: We were dispatched an aircraft that had previously been reported with a directional control discrepancy with the right main gear (time frame between this being reported and me getting this aircraft I assume was less than 15 min). This aircraft was not taken off the line for maintenance to check. In the aircraft book I had not seen this discrepancy listed when I opened it. I had gone out and done a preflight of the aircraft and did not see any issue with either landing gear (treads and wheel pressure were all fine and no sign of brake fluid leak). We took off with no incident. We proceeded to ZZZ where we did a few landings. I noted that the aircraft slid a bit which I thought was my new student locking up the brakes. I told him; 'I have controls' and told him to get off the brakes (also visually inspected his feet were off). I assumed it was due to improper use of brakes and we continued to do landings. On our last takeoff at our rotation speed; I noticed the aircraft's right wing dip and an 'odd' experience in the rudder pedals. I believed it was a gust of crosswind (as we experienced this multiple times during our ground reference maneuvers earlier). I took controls and had us climb. However; after thinking about the sensation I got from the rudder pedals I came to the conclusion that my wheel might have been deflated. I decided I wanted to fly back to ZZZ as the runway was longer; wider and ATC could inspect my gear. I came in and Approach addressed me as 'priority aircraft' which I responded that we were not in an emergency as I wanted my tire inspected first before I declared my situation as an emergency (At no point did I declare myself as an aircraft in an emergency). Once I was handed off to Tower I noticed an ambulance and firetruck holding short of the runway. I did a low approach for [Runway] XXR where I was told my gear looked fine. I concluded with a landing and noticed no issue on my landing or taxi. Maintenance followed me back and inspected the tire which they found no issue with.I do respect the fact that as the PIC of this flight I hold the final authority for the safety of the flight. However; this aircraft should not have made it through to be redispatch moments after it was just reported as 'having a discrepancy'. At the time I heard 'Green' aircraft in the pattern. If I was a few minutes early or late a 'Green' could have easily been given this aircraft. Sending a solo student up with an aircraft with known directional control issues very easily could have resulted in a far worse safety report. I believe an outdated software resulted in this. There were a lot of people this problem slipped through and all of us had been trained by the best flight school in the world. I believe any aircraft that has been reported not fit to fly should be marked by the computer system and shouldn't be able to be redispatch. As noted above; this problem had slipped through a number of very well trained personal. Just like the swiss cheese model when analyzing an accidents or incidents. This problem should have been picked up but its wasn't and I believe this highlights a vulnerability in our procedures. This problematic aircraft could have very easily ended up in the hands of a solo student. I would recommend software that allows the dispatcher the ability to straight away remove an aircraft from the line without having to wait for the aircraft's book to be brought in. Or simply marking an aircraft as having been reported as having a discrepancy.




Synopsis: GA nstructor reported loss of control during landing and takeoff and discovered that this issue was not addressed by maintenance before flight.
