What happened
During an on-demand passenger charter flight, a MU-300 experienced a significant runway excursion while attempting to land on runway 30. The aircraft was operating under instrument meteorological conditions, with recent weather reports indicating the presence of snow and freezing rain in the area. Prior to the arrival, the flight crew was informed that braking action on the asphalt runway was reported as fair to poor.
As the aircraft approached the runway, radar data revealed that the plane was traveling at a ground speed exceeding 200 knots between the final approach fix and the runway threshold. Additionally, a significant localizer deviation was noted 5.5 nautical miles from the antenna. The flight crew had not received updated weather observations for the destination airport until approximately 30 nautical miles from the field. The aircraft sustained substantial damage during the overrun event, though no fatalities or injuries were reported.
Findings
Several contributing factors were identified regarding the approach and landing. The pilot in command was unaware that runway 30 possessed a 0.7 percent downslope, a detail that was missing from the company's airport directory, although the official directory at the time did include this information. The lack of stabilized approach criteria within the operator's training manual was also noted, as the company had no established procedures for executing a missed approach or go-around based on approach stability.
Furthermore, the aircraft's operating manual did not provide specific landing performance data for the MU-300 on runways covered in ice or snow. While the crew was aware of the wind conditions and poor braking action, the high ground speed and the runway slope contributed to the loss of control during the landing phase.
