(CNN) – A transatlantic flight was forced to divert to the Republic of Ireland because a pilot spilled a cup of coffee on the aircraft's controls, it has emerged.
The 49-year-old pilot, who has over 13,000 hours of flying experience, had been given a cup of coffee without a member by cabin crew and accidentally knocked it over as the plane was flying over the North Atlantic Ocean, carrying 11 crew and 326 passengers.
Some of the liquid spilled onto the audio control panel, which became very hot and produced smoke and a burning smell. The damage caused "significant communication difficulty for the flight crew," and forced them to wear oxygen masks, the report said.

The Air Accidents Investigation Branch said there were no injuries and that the airline had since changed its procedures to ensure cup lids are provided for flights on all routes.

"After the aircraft was fully inspected and repaired by our team of engineers, the flight continued through Manchester due to the legal operatin g hours of the crew. As safety is always our top priority, we have comprehensively investigated this incident and reviewed the procedures of liquids in the cockpit. Our crews were reminded of careful handling as well as using appropriate containers for their water or coffee. We apologize for any inconveniences the diversion might have caused to our guests. "
