Narrative:

On the date of the above incident, I went for a flight with another pilot for the purpose of evaluating his aircraft for potential use in conventional gear training. On a landing there was a severe wind shear experienced and the pilot appeared to be getting into a dangerous situation. In reaction,I attempted to assist the pilot; however, he over-controled the aircraft and ground-looped it. I believe that the situation here can be prevented by ensuring that any familiarization with conventional gear aircraft need only be done with a qualified instrument in the aircraft. I feel that the pilot became somewhat complacent due to the fact that he was flying with an instrument--even though I (an instrument) was not qualified in the aircraft (or serving in that capacity), and thus I was relying solely on his PIC responsibility, skill and authority throughout.

Title: GA SMA TAIL DRAGGER GND LOOP ON LNDG.

Narrative: ON THE DATE OF THE ABOVE INCIDENT, I WENT FOR A FLT WITH ANOTHER PLT FOR THE PURPOSE OF EVALUATING HIS ACFT FOR POTENTIAL USE IN CONVENTIONAL GEAR TRNING. ON A LNDG THERE WAS A SEVERE WIND SHEAR EXPERIENCED AND THE PLT APPEARED TO BE GETTING INTO A DANGEROUS SITUATION. IN REACTION,I ATTEMPTED TO ASSIST THE PLT; HOWEVER, HE OVER-CTLED THE ACFT AND GND-LOOPED IT. I BELIEVE THAT THE SITUATION HERE CAN BE PREVENTED BY ENSURING THAT ANY FAMILIARIZATION WITH CONVENTIONAL GEAR ACFT NEED ONLY BE DONE WITH A QUALIFIED INSTR IN THE ACFT. I FEEL THAT THE PLT BECAME SOMEWHAT COMPLACENT DUE TO THE FACT THAT HE WAS FLYING WITH AN INSTR--EVEN THOUGH I (AN INSTR) WAS NOT QUALIFIED IN THE ACFT (OR SERVING IN THAT CAPACITY), AND THUS I WAS RELYING SOLELY ON HIS PIC RESPONSIBILITY, SKILL AND AUTHORITY THROUGHOUT.
