Analysis

The acft made an off-arpt forced landing after the engine lost power during takeoff. The flt instructor and the plt receiving instruction had flown this acft for an earlier session of training during the morning. After a break and briefing the acft was restarted. During the engine run-up the engine ran rough and the mixture was leaned for remedial action before further run-up and check. Engine had been started on the left tank which was used for the previous flt. Sometime prior to takeoff the right tank was selected. At about 350 ft AGL after takeoff the engine lost power. The CFI took over and checked most of the controls with no mention of the tank selector positioning. The engine did not regain power before the CFI cut the throttle for the landing.
