## Analysis (aircraft 1)

The student pilot reported that, he was taxiing on the parking row centerline and did not see that another airplane had moved and came to a stop about 5 feet into the taxiway. The left wing of the taxing airplane collided with the propeller of the other airplane, resulting in substantial damage to the left wing and aileron. The other airplane sustained minor damage to the propeller. The pilots of both airplanes reported that there were no preaccident mechanical malfunctions and failures with the airplanes that would have precluded normal operation.
