What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)Crew declared emergency during taxi for takeoff due to smoke in the cockpit. Aircraft taxied back to ramp without incident. Maintenance found the smoke was from the #1 generator control panel that maintenance suspects had been saturated with water that came from cargo pallets that had been loaded on the aircraft after the pallets had been on the ramp in the rain. The water is suspected to have seeped through the floor during pallet loading. The #1 generator control unit was removed and replaced, and the aircraft was returned to service.
