The problem was spotted when the plane landed in Dubai for refuelling on Saturday morning. The aircraft is not expected to be ready for departure until Monday morning.
“We had initially hoped to get away again on Saturday evening but that turned out not to be possible,” said Kajsa Moström, a spokeswoman for tour operator Apollo.
“We are now flying in with a spare part, which will arrive on Sunday evening. If all goes according to plan, the plane will be able to lift off early on Monday morning,” said Moström.
The passengers have been provided with hotel accommodation until such time as the plane is ready to take them home.
