What happened
The pilot was performing a 45-degree entry to the traffic pattern on the downwind leg when the Mode S Traffic Alert & Collision Avoidance System (TCAS) indicated the presence of several other aircraft in the vicinity. During this time, the pilot also received an audible "traffic traffic" warning.
In response to these alerts, the pilot increased his visual scan due to concerns that another aircraft might be positioned above or below him within the pattern. This heightened focus contributed to a hard landing. Upon impacting the runway, the right tire sustained damage, causing the aircraft to swerve to the right, across the grass, and onto an adjacent taxiway. There were no reported injuries.
