Flight History
On 6 August 2012, an Embraer EMB-505 Phenom 300 aircraft, registration CN-MBR, departed from Geneva (LSGG) at 12:59 UTC on a commercial flight to St. Gallen-Altenrhein (LSZR). After the initial call to St. Gallen tower, the crew accepted a direct approach to runway 10 using the instrument landing system (ILS) following an inquiry from the air traffic controller. Shortly thereafter, the landing gear and flaps were extended. The flaps jammed at approximately 10 degrees, and the FLAP FAIL warning message was displayed. The crew executed a go-around shortly before landing. The landing gear remained extended, and the flaps stayed jammed for the remainder of the flight.
Approach and Overrun
The crew immediately commenced a second ILS approach with jammed flaps. According to manufacturer information, this configuration required an increased approach speed. During the second approach, the crew had difficulty reducing the airspeed to this increased approach speed. At 13:40 UTC, the aircraft touched down on the wet runway at an indicated airspeed of 136 kt, approximately 290 meters after the runway threshold. The aircraft could not be brought to a stop on the remaining runway length. It rolled over the end of runway 10, broke through the aerodrome perimeter fence, and overran the road Rheinholzweg, which runs perpendicular to the runway centerline. At the time, a public transport bus was traveling on that road. The aircraft rolled very close behind the bus and came to a standstill in a maize field, approximately 30 meters from the end of the runway.
Damage and Injuries
The aircraft was badly damaged. The accident also resulted in crop damage and damage to the aerodrome perimeter fence. The female passenger and the two pilots were not injured.
