The crew of the Learjet 6 reported ice accumulation and altitude swings exceeding 700 feet to air traffic control immediately before the crash. [^1]

Air traffic control had cleared the pilots to divert around the dangerous storm system. [^2] The crew notified controllers of icing and turbulence at 35000 feet. They requested to climb to 37000 feet before declaring an emergency. [^3]

The same aircraft, registration N722BD, received an air traffic control warning in May 2026 after crew reported inability to maintain altitude during turbulence. [^4]
