What happened
On June 2, 2013, an Aero AT3 was performing a landing attempt at the EPML aerodrome. During the approach, the student pilot experienced a bounced landing, causing the aircraft to rebound from the runway surface and gain a small amount of altitude.
In an attempt to soften the landing, the student pilot applied additional power while simultaneously applying left rudder and left aileron input. This sequence of actions caused the aircraft to bank heavily to the left. The instructor on board attempted to intervene by leveling the flight path and initiating a go-around procedure. However, the student pilot maintained excessive control inputs, preventing the instructor from effectively correcting the aircraft's attitude. Consequently, the left wingtip and aileron made contact with the runway surface.
The investigation
The PKBWL investigation focused on the control inputs applied by the student pilot during the bounce and the subsequent inability of the instructor to regain control of the aircraft's flight path.
