Embraer S A EMB-505 N327FL accident near Eden Prairie, Minnesota

Probable cause

The flight crew's failure to execute a go-around during a non-stabilized approach, which resulted in a runway overrun.

NTSB analysis

The flight crew of the light jet was conducting a landing to a wet 5,000-ft-long runway. Their preflight calculations indicated an approach speed of 110 knots given the airplane's estimated landing weight. Data obtained from the flight recorder showed that, as the airplane descended through about 500 ft above ground level on final approach, its speed was 186 knots and its rate of descent was over 3,000 ft per minute. The airplane crossed the runway threshold about 158 knots, and touched down about 1,000 feet down the runway about 145 knots. The airplane subsequently departed the end of the runway, impacted obstructions, and came to rest upright on a four-lane highway about 1,000 ft beyond the runway surface. A postaccident examination of the engines, airframe, and braking system revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.

The operator's procedures stated that all approaches to land must be stabilized at 500 feet above airport elevation, and any approach that became unstabilized required an immediate go-around. Among the company's criteria for determining a stable approach was: airspeed no more than 20 knots over target, and descent rate no greater than 1,000 ft per minute. During the approach, the airspeed was 76 knots over the target approach speed and the descent rate of 3,000 ft per minute greatly exceeded the criteria for a stabilized approach.
