Final Report: Slush, crosswind factors in nosegear separation
Cessna 551 Citation II/SP, Coeur d’Alene, Idaho, Dec. 2, 2007–The Safety Board attributed the landing accident involving the CCM Aviation Citation to the pilot’s failure to maintain aircraft control during landing rollout. The slush-contaminated runway and the crosswind were factors. After the pilot touched down on Runway 23 at Coeur d’Alene Air Terminal, the airplane began hydroplaning to the right. He added power to the right engine but the airplane continued drifting right and struck a runway sign concrete pad.
The nosegear broke off and damaged the leading edge of the left wing.
The pilot had been told that there was three-quarters of an inch of snow on the runway, and the wind was from 170 to 190 degrees at 16 knots, gusting to 22 knots. After landing, he found that Runway 23 had 2.5 inches of slush on it. No one was injured in the accident.
