What happened
The aircraft was moving along a taxiway covered with snow when it suddenly changed direction and struck an automobile. The car was stationary, positioned on the edge of the paved surface. At the time of the incident, the ambient temperature was approximately zero degrees Fahrenheit. The pilot later explained that loose snow had accumulated on the taxiway, creating hazardous conditions. Concerned that applying the brakes might cause them to freeze due to the cold weather, the pilot avoided using them in an attempt to maintain control and prevent swerving.
The investigation
Investigators examined the scene where the collision occurred. They noted the presence of snow on the taxiway and the freezing temperatures. The pilot's account of avoiding brake usage due to fear of mechanical failure from cold was recorded as part of the factual narrative regarding the loss of directional control.
Findings
The primary factor contributing to the accident was the pilot's decision-making process in adverse weather conditions. The combination of a snow-covered surface and sub-freezing temperatures created a high-risk environment for ground operations. The pilot's choice to refrain from using brakes, while intended to prevent mechanical issues, likely contributed to the inability to maintain a straight path on the slippery surface.
Safety message
Pilots operating in freezing conditions with snow on the ground should carefully evaluate the risks of taxiing. While brake freezing is a valid concern, alternative strategies for maintaining directional control and ensuring safety should be considered before proceeding onto contaminated surfaces.
