What happened
During an approach to runway 32, the pilot transitioned from a VOR approach to a visual straight-in approach after descending through 2,500 feet and exiting the cloud layer. Upon aligning with the runway, the pilot observed surface contamination, which was described as potentially consisting of ice or compacted snow covered by fresh snow. The crew established a plan to execute a go-around if the aircraft failed to decelerate sufficiently by the runway midpoint.
The aircraft made contact with the runway surface within the initial third of the available distance. As the plane reached the middle of the runway, it began to fishtail. The pilot subsequently initiated a go-around procedure, during which power was increased and airbrakes were retracted. However, the aircraft failed to stop, leading the first officer to observe that the remaining runway was insufficient before the plane entered the snow. Prior to the approach, a Unicom broadcast had reported nil braking action, and a Notice to Airman was active for the airport, warning of an icy runway with nil braking action.
Findings
- The runway surface was contaminated with snow and/or ice.
- A Notice to Airman was in effect specifically warning of nil braking action due to icy conditions.
- The aircraft was unable to maintain directional control and stop within the remaining runway length during the go-around maneuver.
