What happened
During the final stages of an approach to the airport, the pilot reported maintaining a normal approach procedure with an indicated airspeed of 100 knots. Environmental conditions at the time included winds originating from 110 degrees at approximately 10 knots. As the aircraft reached the short final phase, the pilot encountered a significant gust of wind from the right side of the aircraft.
After the pilot performed corrections to compensate for this wind gust, the aircraft experienced a sudden and severe drop toward the runway surface. This descent occurred without prior warning to the crew. Eyewitnesses on the ground observed that the approach appeared routine until the moment the aircraft descended sharply and bounced upon contact with the runway.
Findings
Reports indicate that a thunderstorm had moved through the immediate vicinity just before the aircraft began its approach. The pilot noted that a windshear encounter is the suspected cause of the sudden loss of altitude and subsequent impact.
