What happened
On May 8, 2013, an Aero Boero AB-115, registration PP-GMR, was conducting a commercial pilot training flight at the Londrina Aerodrome in Paraná, Brazil. The flight, operated by Aeroclube de Londrina, carried an instructor and a student. After performing maneuvers in the southern sector of the aerodrome, the aircraft attempted to land.
During the landing roll, as the pilot began to lower the tail, the aircraft experienced a leftward yaw. In an attempt to correct this directional deviation, the instructor took control of the aircraft and applied right rudder. This intervention caused the aircraft to swing abruptly to the right, resulting in the left wingtip making contact with the ground. The aircraft eventually came to a stop at a 90-degree angle to the runway. The impact caused light damage to the left wingtip and aileron, but both occupants remained uninjured.
The investigation
CENIPA's investigation confirmed that all relevant documentation for the crew and the aircraft was valid, including medical certificates for the pilots and the airworthiness certificate for the aircraft. The aircraft was within weight and balance limits, and maintenance records for the airframe, engine, and propeller were up to date. The investigation focused on the sequence of control inputs during the landing phase and the experience levels of the crew members involved.
