Raytheon 390 Premier I, G-FRYL

Summary:

During descent the crew reported experiencing the loss of airspeed information followed by the loss of all three electronic flight instrument system (EFIS) displays. The investigation concluded that the loss of air data information was due to a blockage in the right pitot system caused by moisture ingress which subsequently froze. However, despite exhaustive testing, it was not possible to determine the cause of the loss of all three EFIS displays. One Safety Recommendation is made.
