AAIB investigation to Beech B200, G-YVIP
Electrical arcing and smoke in the cockpit during final approach, Bournemouth Airport, 23 October 2020.
Summary:
The aircraft landed safely after an electrical fire and smoke in the cockpit during the final approach. The operator’s investigation found that the commander’s circuit breaker (CB) panel showed evidence of moisture ingress and the back-lighting circuit board was burned. They concluded that the most likely scenario is that rainwater entered the cockpit through the storm window, which is above the CB panel. Following this event, the operator took action to ensure that all their King Air aircraft have an improved storm window seal and that their aircraft are parked inside a hangar when they are not in use.
