What happened
The pilot reported that the aircraft was on final approach for landing on runway 15 when it encountered wake vortices generated by an airplane that had just departed from runway 33. At approximately 50 feet above ground level, the aircraft experienced a hard roll to the left, which triggered the stall warning horn.
In response, the pilot applied power, causing the aircraft to roll hard to the right. Although the pilot successfully stopped the roll, the nose of the aircraft dropped significantly. The right main landing gear then impacted the runway surface, resulting in substantial damage to the airframe.
The pilot did not report any anomalies with the airframe, flight controls, engines, or weather conditions at the time of the incident.
