What happened
On December 30, 2013, an Aero Boero AB-115, registration PP-GQW, was conducting a local flight for Private Pilot training at the Carazinho Aerodrome in Rio Grande do Sul, Brazil. The aircraft was occupied by an instructor and a student pilot.
During the seventh landing of the flight, specifically during a touch-and-go maneuver, the student pilot lost the centerline to the right. The instructor took control of the aircraft and applied full left rudder to correct the deviation. This action caused the aircraft to trend toward the left. In an attempt to recover, the instructor applied right rudder and attempted to lift the aircraft off the ground; however, due to insufficient airspeed, the aircraft briefly climbed before returning to the runway.
Following this sequence, the aircraft veered off the runway and performed a 1ered 180-degree turn on the grass to the right. The impact resulted in the failure of the landing gear. The aircraft sustained substantial damage to the propeller, engine, and landing gear, along with minor damage to the fuselage and left wing. Both occupants were uninjured.
The investigation
CENIPA's investigation confirmed that both pilots held valid medical and technical certificates. The instructor was highly experienced, with 1,000 flight hours in the model, while the student pilot had 26 flight hours. The aircraft was found to be airworthy, with all maintenance logs up to date, and was within weight and balance limits at the time of the accident.
