Ground Event / Encounter Loss Of Aircraft Control
Aircraft Aircraft Damaged
Aircraft; Human Factors
I was flying the aircraft from the rear-seat (pilot seat; two seats in the aircraft with one is front of the other) performing multiple touch & go's. On the last landing; the plane had bounced which started to cause the CG to shift making the aircraft want to swerve from left to right. In attempt to prevent the aircraft from swerving any further; I attempted to put in the correct rudder inputs while the aircraft began to swerve. The passenger (an experienced pilot) then took controls and also attempted to prevent the swerving. The aircraft resulted in ground looping on the runway which caused damage to the right landing gear.
Riding in front (passenger/copilot) seat while partner performing multiple touch and goes. on the last landing; he bounced and started to lose control; on approximately the third left/right oscillation; I took controls in attempt to regain control but it was too late and the plane ground looped. RH landing gear was damaged.
Two pilots in a Christen Eagle II reported a loss of control and ground looped during landing.
