G-TCCF, an Airbus 330-200 aircraft operated by Thomas Cook Airlines, was conducting Condor Airlines flight CFG116 from Frankfurt/Rhein-Main (EDDF), Germany to Cancún Intl (MMUN),
Mexico. During cruise flight, liquid was inadvertently spilled onto the number 1 Audio Control Panel (ACP), causing all lights on the unit to illuminate. Initially, the number 1 ACP, then the number 2 ACP became hot, and began to emit a burnt electrical odour. At approximate position 56°03’N/031°11’W, smoke started to come out from the number 1 ACP. The flight crew donned their oxygen masks, initiated a diversion to Shannon Intl (EINN), Ireland, and sent a MAYDAY message using ACARS. The flight crew jettisoned fuel in order to achieve maximum landing weight, and the aircraft landed at EINN without further incident. 1 passenger and 4 crew members were attended to by paramedics and sent to local medical facilities for a precautionary assessment before being released.
