Narrative:AAIB investigation to Beech B200, G-YVIP: Electrical arcing and smoke in the cockpit during final approach, Bournemouth Airport, 23 October 2020. Although the aircraft sustained minor damage, the AAIB considered the incident as "serious", and the following is an exceprt from the AAIB report...
"The aircraft was on final approach to Bournemouth Airport in clear weather, at a height of approximately 1,200 ft. Very shortly after selecting approach flap, they noticed a yellow glow and smoke coming from behind the commander’s CB panel. They attempted to isolate the problem by operating the master switch gang bar, which switches off the battery and electrical generators, but this had no effect, so they declared a MAYDAY.
The first officer tried to reach the fire extinguisher under his seat but found this to be difficult because of his shoulder straps. After landing the crew evacuated the aircraft on the runway and the airport fire service attended but the smoke stopped without intervention when the aircraft was shut down.
=AAIB Conclusion=
The operator’s investigation found evidence of moisture ingress, overheat and burning damage in the commander’s CB panel, which is under the left storm window. They concluded that the most likely scenario is that moisture entered the cockpit through the window, eventually resulting in electrical breakdown of the CB panel back-lighting circuit board.
=Safety actions=
The operator has installed the improved window seal across their fleet of King Air aircraft, and whenever possible, their aircraft will be parked inside the hangar and only towed outside when required.
