Keep cockpit windows closed to prevent rain from causing damage to electrical panels.

Mechanics, as long as you batten down the cockpit hatches, your Chinook is well protected from the weather.
The weather we’re talking about is rain. Your Chinook cockpit contains electrical equipment, including multi-functional displays. You should never leave the cockpit window open because a sudden rain shower and electricity don’t mix.
The right (pilot) and left (co-pilot) cockpit circuit breaker panels, generally referred to as the AC and DC electrical panels, sit next to the windows. If rain contacts the circuit breakers, you could be looking at fried breakers and wiring damage.
Water can damage electrical panels
If the cockpit windows are accidentally left open during a shower, let the breakers dry before you start your aircraft. Then if you turn on the aircraft and circuit breakers pop or nothing works, it’s time to call your electrician.
