DHC-8-402, G-JECG

Summary:

During flight in icing conditions, the flight crew experienced multiple flight instrument failures which were consistent with icing of the pitot/static probes. Recorded flight data indicated that the standby pitot/static probe heat switch had not been selected ON prior to flight, and the investigation concluded that, in all probability, the remaining two pitot/static probe heat switches had also not been selected ON. Non-standard checklist procedures and distractions may have created an environment in which the selection of the probe heat switches to ON was missed before takeoff, and not detected until after the icing encounter.
