Aircraft; Human Factors
During takeoff I over rotated and experienced adverse yaw. Landed the aircraft causing skin damage.
Aircraft Checkout. Left seat pilot was a CFI-AI with over 3;000 hours. I asked him who would be PIC. Since he was an owner (club aircraft; new to the S-LSA airplane) he said he would be PIC. I was in the right seat as check pilot. I had flown the airplane three times for a total of 1.0 hour; as a maintenance check flight (solo) prior to its return to service two years ago.PIC lost control of the aircraft at rotation; high pitch attitude...aircraft departed the runway to the right. It was very confusing as it seemed the aircraft had the ailerons hooked up backwards. Pilot was commanding left turn; left aileron; but the aircraft was going right. In hind sight I believe this was due to EXTREME ADVERSE YAW with aileron deflection. Pilot was definitely out of control; not getting the expected result from his inputs.I heard him mutter; 'Your aircraft;' I cut the power; lowered the nose and was able to land on the runway; going sideways now right to left. We departed the left side of the runway with the left main gear (tricycle gear).Upon inspection; we damaged the right wingtip (on takeoff departing to the right); and damaged the left wingtip; and bent the skin on the outboard part of the left aileron (after landing; trying to stay on the runway).I believe this incident happened due to the ASTM Standard; and unexpected control response at slow speed and high AOA.
During the initial takeoff for an LSA checkout two instructors describe a loss of control incident from their perspective; resulting in aircraft damage and a runway excursion.
