Analysis

The plt-in-command (PIC) stated he was taking off on a training flt with a student, using a 2 place, ultralight vehicle. During the takeoff roll, the rubber tread separated from the tailwheel & it began to dig into the airstrip. The PIC reported that after becoming airborne, the wind shifted to a quartering tail wind, and consequently he steered the vehicle to the left to avoid hitting terrain. However, the left main gear hit a dirt bank & the ultralight came to rest in a thicket. The PIC was registered with aopa air safety foundation as an asf examiner. Also, he was designated by the manufacturer to give instruction in the tierra ii ultralight as required by FAA exemption 3783. The PIC had logged aprx 25 hrs in single eng land acft, but had accumulated aprx 850 hrs in ultralight vehicles.
