An airline which twice abandoned take-off attempts when passengers said they saw fuel gushing from a plane's wing has suffered another safety scare.
Britons flying with Phuket Air out of the United Arab Emirates on Sunday were left stranded by the halted take-offs.
On Wednesday, a separate Phuket Air Boeing 747 had to return to Gatwick three hours into a flight to Bangkok because of a hydraulics fault.
UK officials have grounded the plane until repairs have been completed.
Engine shut down
It has emerged that an engine had to be shut down while the plane was airborne.
The plane, which had taken off from the Sussex airport at 0830 BST and landed back at 1137 BST, has been grounded by the Department of Transport.
A spokeswoman said it would not be permitted to leave the UK until the damaged engine had been repaired or replaced.
An airline spokeswoman said on Wednesday: "There were 82 people on today's flight, which flew into Gatwick from Sharjah last night and had suffered a hydraulics problem.
"Though it was thought the fault had been corrected, the plane suffered the same problem this morning."
